The Chicago 0,0 Riverwal AR experience provides a novel, interactive way for users to explore historical photographs sourced from museum archives. As users walk along the Chicago River, they are instructed to use their smartphone or tablet to view these photographs alongside the current views of the city. By matching location and view orientation the Riverwalk application creates an illusion of &ldquo;then and now&rdquo; co-extant. This superimposition of the historical photographer&rsquo;s view and the user view is the basis of educational engagement for the user and a key factor in curating the images and the narrative surrounding them, facilitating a meaningful museum experience in a public, outdoor context. 
As such, creating the AR experience involves a complex back-and-forth between 3D and 2D experiences of locations: the historical
images are 2D, taken from specific locations through specific optics and views; the user, present at the real-world 3D location is
orienting their own camera and 2D phone video screen in space in order to achieve the AR experience and illusion; and the ultimate experience of superimposition is one of seeing two integrated views simultaneously: the stream of data taken from a smartphone&rsquo; camera and the historic image. The site-specific nature of the publication makes it necessary to utilize a virtual 3D environment in which to place 2D augmented content that enhances the experience. This content needs to be placed in such a way so that the designer can accurately visualize what the user will see on screen from a particular location. 
The first episode of the Riverwalk AR experience focuses on a single block between N. LaSalle and Clark Streets; the site of
the Eastland Disaster in 1915. The site was selected because of the importance of this historical event - the sinking of the Eastland
cruise ship 100 years ago was the largest single loss of life in Chicago’s history - and because of the abundant media available
in the archive including extensive photographic documentation, newspapers and film reels. Moreover, the site potentially offers
natural way, finding characteristics that are amenable to developing our project, including a newly built pedestrian walkway along
the river with viewing platforms, views from pedestrian walks along the bridges, and historical markers. Additionally, the urban environment offers many features providing sufficient quality for robustly tracking user location based on their cameras from a variety of views and positions. This is a typical scenario in the creation of public outdoor AR experiences; the quality of content and narrative are the primary motivations for their creation.

Chicago 0,0 is a mobile application aimed at presenting 2D media content from archives of historical media through the use of augmented reality.

Riverwalk: Incorporating Historical Photographs in Public Outdoor Augmented Reality Experiences

MS candidate and Italian exchange student, Marco Cavallo presents his research in Augmented Reality (AR). His presentation will introduce a user-centered AR approach for publishing 2D media archives as AR content. Relevant technical considerations for developing an effective application in the Unity 3D game engine for public outdoor AR experiences that leverage context-specific elements in a challenging, real-world environment will be discussed. This research provides enabling technology for the the Riverwalk project - Chicago 0,0, a novel app-based AR experience that superimposes historical imagery onto matching views in downtown Chicago along the Chicago river Riverwalk pedestrian mile. Historical photographic and filmic views of the sites along the river are superimposed onto buildings, bridges, and other architectural features through image-based AR tracking, providing a striking experience of the city&rsquo;s history as rooted in extant locations within the community. 
This work is done in collaboration with Geoffrey Alan Rhodes, Assistant Professor at the School of The Art Institute of Chicago.

Riverwalk: Incorporating Historical Photography in Public Outdoor Augmented Reality Experiences

This paper presents a novel approach for the design of creative location-based mixed reality applications. We introduce a framework called DigitalQuest that simplifies adding geolocated virtual content on top of real-world camera input. Unlike previous work, which relies solely on markers or image pattern recognition, we define a &ldquo;mirror world&rdquo; that facilitates interactive mixed reality. DigitalQuest consists of an editor that allows users to easily add their own content as desired and a mobile application that loads content from a server based on the location of the device. Each piece of virtual content can be organized through the editor so that it appears only in certain circumstances, allowing a designer to determine when and where a virtual object is attached to a real-world location. We have used our editor to create a series of futuristic scavenger hunts in which participating teams must solve puzzles in order to access new virtual context appearing in a mixed reality environment via a mobile phone application. In this paper, we introduce our editor and present an example scavenger hunt game, Morimondo, that was built using it. Specifically, we describe our technique to utilize camera and motion sensors on the mobile phone to enable an appropriate level of user engagement within this game. We are able to obtain realistic augmentations with accurate positioning by leveraging sensor fusion and through the use of filters that compensate for sensor noise, using image processing only for error correction or in special situations. The initial success of this project leads us to believe that DigitalQuest could be used to design a wide range of creative multi-user mixed reality applications.

DigitalQuest: A Mixed Reality Approach to Scavenger Hunts

Despite much progress and increased interest, mixed reality applications are not yet in widespread use by the general public. Our framework, DigitalQuest, facilitates the creation of mixed reality applications, providing application designers with the ability to add custom virtual content to the real world. Specifically it supports the creation of futuristic &ldquo;scavenger hunts&rdquo;, where multiple users search for virtual objects positioned in the real world, and where each object is related to a riddle or a challenge to be solved. Each player can compete with the other participants by finding virtual objects and solving puzzles, thereby unlocking additional challenges. Virtual objects are represented by animated 3D meshes locked to a determined position in the real world. The objects are activated when a player gets within a proximity threshold and then taps the object on the screen of his or her mobile phone. In our demonstration application, configurable virtual content appears, followed bya question that must be answered in order to be pass to the next challenge. The displayed content may consist of images, video and audio streams, graphical effects, or a text message that provides hints on how to advance in the game. The editor makes it easy to create puzzles that can be solved by exploring the surroundings of the virtual object in order to discover clues and making use of location-specific knowledge. When a participant figures out the correct solution, he or she scores points related to the complexity of the challenge and also unlocks remaining puzzles that cause new virtual object to appear in the world. At the end of the event, the player with more points wins. 
DigitalQuest provides a general approach for adding user-defined virtual content to the real world, allowing the personalization of a &ldquo;mirror world&rdquo; that could be explored by anyone with a GPS-enabled mobile device simply by using our application. Though these Quests were originally meant for creative exploration and mixed reality scavenger hunts, our framework also could potentially support a wide range of applications, for example: team building and team-work enhancement events, tourism, virtual galleries, and cultural heritage. As we demonstrate in our case study, DigitalQuest can also be used to create augmented narratives, engaging users by telling an interactive story that makes use of real-world architecture. We also believe that our framework could be used to provide context-aware opportunities for learning. DigitalQuest could additionally be used for marketing purposes, allowing companies to organize events with customized content in order to make customers more attached to the brand. Ultimately, the framework is meant to provide a way for designers to flexibly express creative approaches to generating virtual content within the real-world.

Google Street View can be considered as an online browsable dataset consisting of billions of street-level panoramic images acquired all around the world. Since 2007, the company has continuously improved and updated its global image database, now collecting on average one panorama each 5-10m in urban environments. Google provides public APIs for requesting virtual camera views of a given panorama from its GPS position or unique identifier. These views are rectilinear projection of the spherical panorama with a user selected field of view, orientation and elevation angle. These views can be considered as undistorted images taken from pinhole cameras, free of distortion, and need to be partially overlapped in order to reconstruct the 360 degree panorama. 
Additionally, the speed with which Google&rsquo;s laser scanners get reflected by surfaces allows the company to calculate the distance from the camera to objects or buildings, allowing the creation of 3D models to be used in other applications such as Google Earth. Google API indeed provides a way to obtain the depth map corresponding to a specific panorama, information that we will exploit in order to reconstruct the 3D scene. Once decoded and visualized in space, this depth data and the models generated from it may turn out to be useful for many different applications like navigation and augmented reality, but also virtual reality oriented videogames.

3D City Reconstruction From Google Street View

Despite laser scan 3D point cloud acquisition has greatly improved over the next few years, the process of creating 3D large scale city models is still quite expensive and not straightforward. At the same time, nowadays services such as Google Street View provide a vast amount of geo-registered panoramic imagery, guaranteeing a decent resolution for dense locations at zero cost. Our idea is indeed to leverage this free information provided by Google Street View in order to obtain a cheap and automatizable 3D reconstruction of an urban area, by extracting the depth information related to the great number of panoramic images available online.

A range of platforms facilitate the design of virtual environments. Most commonly, game engines, such as Unity and Unreal, are used for developing and simulating virtual realities. However, such platforms are primarily oriented towards visual design and provide only limited audio functionality. Furthermore, these platforms utilize separate editing and rendering modes, and operate on desktop platforms. Making use of existing research into the development of interactive virtual soundscapes, we introduce a novel user interface that enables the rapid design of both virtual sonic environments, and the assets (i.e. sound objects and sound zones) contained within them. 
Specifically, our UI offers the following contributions: 
<ul>
<li>provides a 3D design environment specific to sonic virtual realities, with specialized components such as sound objects and sound zones;</li> 
<li>offers both interactive and parametric control over the attributes of such components, enabling a precise authoring of highly-detailed environments;</li> 
<li>introduces a multi-cone model for creating 3D sound objects with complex propagation characteristics;</li> 
<li>enables adding dynamism to objects via hand drawn motion trajectories that can be edited in 3D;</li> 
<li>makes it possible to design virtual sound fields at various scales using multiple view and attribute windows;</li> 
<li>offers a unified interface for the design and the simulation of such realities, allowing the user to modify a sound field in real-time;</li> 
<li>operates on the web-browser so that it supports mobile devices, which therefore makes it possible for the user to simultaneously explore and edit augmented sonic realities.</li>
</ul>

This research explores a novel approach to the design of Mixed Reality (MR) applications, which combines elements from markerless and location-based Augmented Reality in order to explore new types of interaction, leveraging a spatial representation of virtual content. In particular, a method is derived for developing both a mobile application, that can be used by people to see augmented content in the real world, and an editor application, which can be used to design and create MR experiences. Currently available mobile technologies needed to achieve these results are exploited, and the integration of sensors in order to improve tracking with a fully location-based approach, in which every content has a defined position in real space is explored. The advantages and the new interaction possibilities enabled by this method are weighed, in order to define the requirements for a custom MR authoring tool and its implementation. Particular emphasis is placed on the mapping between real-world and virtual coordinates and on the possibilities enabled by real-time editing, which allows the designer to preview the MR experience and also to interact with users.

This project&rsquo;s purpose was to investigate the ability of virtual reality to teach music. An application was developed for the CAVE2&trade; and Microsoft Hololens, and their ability to teach music effectively was analyzed. Both the applications teach the user how to play &rsquo;Mary Had a Little Lamb&rsquo;on the viola, and each virtual reality platform had itrsquo;s own benefits and drawbacks. An interface was created for both platforms that shows the user the correct bow direction, tempo, fingering, and sheet music. Additional features included adjustable tempo and a metronome that can be turned on and off. The application was helpful since the user could get visual cues from the graphics while still keeping an eye on his/her instrument. Future goals for the application include songs that can be uploaded by the user, microphone input, more instruments, and better graphics. The results of this research show that music instruction is a viable possibility in a virtual reality environment and will spark developers and musicians to work together to further explore this field.

This paper introduces a user-centered Augmented Reality (AR) approach for publishing 2D media archives as interactive content. We discuss the relevant technical considerations for developing an effective application for public outdoor AR experiences that leverage context-specific elements in a challenging, real-world environment. Specifically, we show how a classical marker-less approach can be combined with mobile sensors and geospatial information in order apply our knowledge of the surroundings to the experience itself. Our contributions provide the enabling technology for Chicago 0,0 Riverwalk, a novel app-based AR experience that superimposes historical imagery onto matching views in downtown Chicago, Illinois along an open, pedestrian waterfront located on the bank of the Chicago River. Historical photographs of sites along the river are superimposed onto buildings, bridges, and other architectural features through image-based AR tracking, providing a striking experience of the city’s history as rooted in extant locations along the river.

Node Kara is an audiovisual mixed reality installation by the artist Anıl Camci. It offers a body-based interaction using a 3D imaging of the exhibition space. With a blurred audiovisual scene in its steady-state, it invites visitors to interact with the multiplicity of layers it holds within. By moving in the exhibition space, the visitors can deblur both the sound and the visuals as they get immersed in the piece. Rather than a detection of discrete events or gestures, Node Kara relies on fluid interactions with continuous visual layers and stochastic audio. This way, the piece reacts to each visitor in a unique way. A video preview of Node Kara can be seen at <a href="https://vimeo.com/anilcamci/nodekara">https://vimeo.com/anilcamci/nodekara</a> (password: nodekara).

October 2016 - Augmented reality (AR) is being used in a very novel and compelling way to engage Chicago residents and tourists into learning more about the city&rsquo;s history. John Russick of the Chicago History Museum teamed with Geoffrey Alan Rhodes at the School of the Art Institute (SAIC) to create Chicago 0,0 Riverwalk, a mobile AR application that superimposes historical imagery onto matching views of Chicago&rsquo;s downtown riverwalk. The first project focuses on a single block between N. LaSalle and Clark Streets, the site of the Eastland Disaster in 1915, in which 844 people lost their lives on a pleasure boat when it rolled over in the Chicago River. On October 19, 2016, journalist Jay Shefsky told the story of how AR to being used to chronicle the tragedy of the <a href="http://chicagotonight.wttw.com/2016/10/19/augmented-reality-app-offers-new-look-eastland-disaster">S.S. Eastland on an episode of WTTW Chicago Tonight television</a>. 
During the development of this application, UIC Computer Science (CS) professor Angus Forbes and his MS student Marco Cavallo, both affiliated with the Electronic Visualization Laboratory (EVL), worked with the SAIC faculty and students on technical considerations that have since been incorporated into the second version of the application software. EVL&rsquo;s expertise enabled better tracking and feature detection of real-world objects; better registration and orientation of the real-world environment with historical photographs; the use of a smart, intuitive interface to help users navigate in the real world and locate historical images; and, better image contrast, even on overcast days with adverse lighting conditions. Together, these technical efforts have contributed to better user experiences. 
In the WTTW story, John Russick of the Chicago History Museum notes the value of this AR application: &ldquo;One of the biggest challenges in communicating history is finding human emotional connections to very old stories … that draw us in a deeper, more meaningful way.&rdquo; Rather than passively view photographs or documentary films, AR enables users to experience history firsthand, in its relevant surroundings.

Augmented Reality App Offers New Look at Eastland Disaster

Umwelt, the German word for environment, is a psychology term referring to the individual&rsquo;s mental image of the surrounding world. This subjective universe is shaped by an organism&rsquo;s unique perception of the environment around them and, therefore, differs from individual to individual. In other words, organisms experience the world through their senses, construct the mental model of their vicinity, and react upon it. Hence, this image never remains static - instead it is constantly refined, as a result of the dynamic nature of the world. Umwelt is closely related to the concept of Situation Awareness, that is the perception of environmental elements, comprehension of their nature, and projection of their near future status with respect to time and/or space. 
Sensory perception (exteroception) of the surrounding environment is, as a matter of fact, restricted to the limitations of biological senses. For example, although we consider humans with five fully developed senses (sight, hearing, touch, smell and taste) as able-bodied individuals, they are essentially blind to a multitude of information that constantly surrounds them. To put things into perspective, both human sight and hearing, can only perceive a fraction of information- part of the electromagnetic spectrum (light waves), and of the sound frequencies accordingly. However, as sensory systems differ among species, other creatures have an entirely different perceptual experience, as they are able to perceive a distinct spectrum of information. 
Despite the fact that our limited human senses restrict our Umwelt and, therefore, our Situation Awareness, Human Augmentics, referring to technologies that expand the capabilities and characteristics of humans, allows us to peek into an invisible &dlquo;other&drquo; world. Thus, some important questions arise: What would the consequences of an expanded perception of the
surrounding environment be, and how would that affect an individual&rsquo;s Situation Awareness? Since our Umwelt is limited by genetics, how would individuals attune with characteristics and capacities that lie beyond human range? Could Human Augmentics possibly expand an individual&rsquo;s Umwelt, leading to improved Situation Awareness? 
Jakob von Uexkull (1864 - 1944), a German biologist who worked on animal behavior studies, cybernetics of life, and muscular physiology, is attributed for coining the term Umwelt. Uexkull&rsquo;s Umwelt is the phenomenal world of a living animal, in which it exists and acts, and as a result is shaped according to the stimuli received from its senses. Due to the fact that individuals, even across the same species, sense the world differently, each animal creates its own unique Umwelt. 
Perception and, as a result, interaction with the world begins with the raw input of data from the environment through the sensory system. Anatomically, the sensory system is part of the nervous system and includes the sensory receptors that act as probes of the environment, parts of the brain that are used for sensory perception, and the neural pathways that connect the brain with the receptors. Notably, humans&rsquo; sensory system consists of five traditional senses: Sight, hearing, taste, smell and touch. The stimulation type and bandwidth of each sensory channel are limited to its characteristics, which in turn constrain the size of the Umwelt.
However not all living organisms possess the same qualitative or quantitative senses. Depending on the environment in which they have evolved, their sensory system may be entirely different than ours; some have more while others have less sensitive senses. Others have quite different ones. Bats and dolphins, for instance, have the ability to calculate orientation and position of other animals and objects through reflected beams of sound, an ability known as echolocation. Sharks and rays, on the other hand, can detect changes in the electric field of their vicinity, an ability known as electroreception. 
Situation Awareness 
It is a well-known fact that humans are capable of sensing only a small fraction of the data that constantly surrounds us. Magnetic fields, infrared light, ultrasound, cosmic rays, radiation are just a few of the things that are completely invisible to us. However, recent technological advances in specialized sensors, enable the detection of some of this information. For instance, geiger counters are used by hazmat personnel to assess radiation levels in nuclear accidents. These technologies provide feedback using one of our existing senses, usually visual or audio, in order to help workers safely perform daily tasks. 
Situation Awareness (SA) is the perception of environmental elements, comprehension of their nature, and projection of their near future status with respect to time and/or space. In other words, it is the awareness of the immediate vicinity, comprehension of the current state of the environment and ability to predict what may happen. Inputs from the sensory system are used by the individual in order to create and update their Situation Awareness state, and as a result, decisions depend on the accuracy of the perceived model. Situation Awareness is tightly associated with experience; somebody less experienced may miss information that a more experienced user will not. To put things into perspective, the hazmat personnel&rsquo;s (that we discussed above) Situation Awareness includes the geiger counter readings, comprehension of their meaning and ability to predict what will happen if they raise above a certain level. 
Despite the fact that sensory systems have been honed by millions of years of evolution, they are very limited to a multitude of data. We are blind to a plethora of information that exists around us, and fortunately most of it is harmless. We depend on our sensory system to interpret the world, and we use our Situation Awareness to comprehend the environment around us and act upon it. As a result, lack of information for a certain situation may lead to misjudgements and accidents. In fact 76% of aviation errors, happen because the pilot did not perceive one piece of the airplane&rsquo;s crucial information. To that end, another important question arises: Given that today&rsquo;s technology can sense some of this invisible information, can we expand the Umwelt and improve Situation Awareness? 
Research Questions 
Genetic defects, diseases or accidents can lead to sense disabilities or complete sense lose, which has been observed to both animals and humans. To that end, individuals learn over time to use the remaining of their senses in order to overcome a disability. Recent scientific discoveries have shown that while this new ability results in anatomical changes of the brain, the responsible regions remain the same. In other words, even though the sensory input channel has changed, the brain will still process the information in the same region|a phenomenon known as Sensory Substitution. 
As a result, Sensory Substitution devices use one or more of the remaining senses to increase an individual&rsquo;s Situation Awareness through a different sensory pathway. More specifically, tactile displays are able to translate external environmental information onto one&rsquo;s skin, through the use of haptics. While these systems are primarily designed for people with disabilities, their concepts can be extended to other sensory deprived individuals, who find themselves in no or limited visibility environments due to external, environmental reasons. For example, firefighters operating within smoky, low visibility hazardous environments or soldiers fighting in pitch black darkness, are more likely to have no Situation Awareness of their surrounding environment. 
The ever-dynamic nature of the world around us, however, makes navigating with a wearable tactile display, a quite challenging task. From feeling the vibrations onto one&rsquo;s skin, comprehending their meaning and correctly acting upon them, to getting inundated with tactile sensory overload, tactile displays have great potential, when communicating information in an eloquent
way. 
In this dissertation we will explore different environment-to-vibration mappings while assessing one&rsquo;s Situation Awareness. Furthermore, we seek to understand whether one's experience with a tactile display would have an effect on their Situation Awareness. Finally, we hypothesize that a one-size-fits-all wearable tactile display would not perform equally well in all environmental scenarios and therefore we are going to explore how different vibration configurations, patterns and environment-to-vibration mappings would affect one&rsquo;s navigation. All of the above are distilled into the following research questions: 
- Could tactile displays be used to increase Situation Awareness of visually deprived individuals? 
- To what extent would Situation Awareness be associated with experience when using a tactile display?

JANUARY 24, 2019 - Daria Tsoupikova, associate professor in the UIC School of Design and an affiliated faculty member of the UIC Electronic Visualization Laboratory (EVL) which is part of the Computer Science (CS) department, recently received a $150,000 grant from the University of Illinois (UI) System&rsquo;s Presidential Initiative to Celebrate the Impact of the Arts and the Humanities. Given how important the arts and humanities are to education, research, scholarship, and public engagement, this newly-created initiative supports the visibility and excellence of the arts and humanities at the UI System&rsquo;s sister campuses. 
Tsoupikova&rsquo;s &ldquo;Transforming Storytelling: Multi-User Virtual Reality Theater for Collaborative Tele-Immersive Exploration&rdquo; is a collaboration with EVL Director of Research and CS associate professor Andrew Johnson, CS/EVL Senior Research Programmer Lance Long, CS/EVL PhD student Arthur Nishimoto, and Chicago-based theater director Jo Cattell, who recently received the Goodman Theatre&rsquo;s 2018 Michael Maggio Directing Fellowship. They will partner with the Goodman Theatre&rsquo;s Alice Rapoport Center for Education and Engagement, whose youth program works with Chicago&rsquo;s diverse demographics of middle-grade and teenage kids (ages 11-18). 
&ldquo;Transforming Storytelling&rdquo; will demonstrate how virtual-reality technology can be both an artistic medium to further immerse participants in live theater experiences and a storytelling medium. Project collaborators will develop multi-user theatrical performances that merge real and virtual worlds with the goal of encouraging stronger theater engagement with tech-savvy younger audiences. Chicago youth will attend performances at the Goodman Theatre and at UIC/EVL&rsquo;s CAVE2&trade;, allowing for immersive participation in the plot lines through avatars, hand-held devices and 3D platforms. 
While non-profit theater groups have great interest in incorporating new technologies in live performances, they don&rsquo;t necessarily have the financial support to do so. UIC&rsquo;s collaboration with the Goodman Theatre can demonstrate that live performance combined with virtual reality is a viable option for immersive theater. 
The UI System&rsquo;s Presidential Initiative selected 14 faculty projects from 53 proposals, which will share nearly $2-Million in funding over the next two years. Of the 14 proposals, all but one was allocated $100,000 or more and eight will receive $150,000 or more. By comparison, the average grant award in 2016 by the National Endowment for the Arts (NEA) was $25,000 and fewer than 40 NEA grants totaled more than $100,000, according to Grantmakers in the Arts.

Abstract: 
Given the adoption of many variations of virtual and augmented reality devices such as CAVE/CAVE2, large virtual reality (VR) capable displays walls/domes, and a growing set of increasingly capable and affordable head-mounted displays (HMD) in both commercial and industrial applications, it has become apparent that not one platform will be appropriate for every use case scenario. HMDs are becoming increasingly more lightweight and powerful, but in collaborative settings there always will be a need for a shared display or environment to bring discussions together. 
The goal of this proposal is to leverage the best of current augmented reality head mounted display technologies: 360 degree field of regard visuals, rendering of graphics over the real world, and personalized views with the best of large display wall environments: high resolution and contrast, shared visual environment, and more accurate tracking. 
With fully immersive HMDs blocking our natural sense of communication and AR still limited by resolution and field of view, combining large VR display walls and AR may provide a middle ground to maximize the growing benefits of interacting together in virtual worlds.

Using Augmented Reality to Assist Seated Office Workers&rsquo; Data Entry Tasks

Two major form factors for virtual reality are head-mounted displays and large display environments such as CAVE&trade; and the LCD-based successor CAVE2&trade;. Each of these has distinct advantages and limitations based on how they&rsquo;re used. This work explores preserving the high resolution and sense of presence of CAVE2 environments in full stereoscopic mode by using a see-through augmented reality HMD to expand the user&rsquo;s field of regard beyond the physical display walls. In our explorative study, we found that in a visual search task in a stereoscopic CAVE2, the addition of the HoloLens to expand the field of regard did not hinder the performance or accuracy of the participant, but promoted more physical navigation which in post-study interviews participants felt aided in their spatial awareness of the virtual environment.

EVL alumna and Associate Professor in Interactive Systems at the Department of Informatics & Telecommunications, National and Kapodistrian University of Athens, Maria Roussou presents her research in immersive eXtended Reality (XR): 
Wednesday, May 3, 2023, 1:30PM 
EVL Continuum Room 2068 ERF 
Dr. Roussou&rsquo;s talk entitled &ldquo:Extending the virtual: the museum as a hybrid experience&rdquo; will discuss the use of advanced digital technologies, such as Virtual Reality, in the GLAM sector (e.g., galleries, libraries, archives, museums, etc.) to create immersive experiences for visitors has come of age. However, to date, the emphasis has been on reconstructing the real to transgress the built environment's limitations. Nowadays, the focus turns to integrating the physical and the virtual. The physical space is highlighted, complemented, and expanded through close coupling with the digital. Tangible objects are integrated and play a leading role in the digital experiences of visitors, creating a hybrid reality. Drawing from a range of high-end immersive eXtended Reality (XR) applications but also lower-end mobile tours created for cultural or informal educational purposes, this talk will explore how the future’s hybrid nature is shifting immersive presentation from the mainly didactic walkthroughs to experiences that are playful, emotive, social and shared, meaningfully interactive, and, ultimately, relevant and resonant to those they are designed for. 
Specifically, Roussou will present aspects of the BRIDGES project, a multi-user, multisensory XR experience set in informal learning contexts, and the EMOTIVE project, which aims to leverage interactive, social, and participatory capabilities. Both combine historical accuracy in representation with dramatic storytelling to enhance knowledge about the past, historical empathy, and resonance.

Abstract: 
Strategizing and sensemaking in immersive environments have predominantly been explored for training, learning, and recreational tasks. The ability to embed these concepts into the data analysis pipeline is recently emerging and has seen limited research. In our work, we present Personal Situated Analytics (PSA) that provides individuals the ability to embed themselves in recorded events in multiple degrees of immersion on the Reality-Virtuality spectrum, evaluate the benefits, and study their exploration patterns. With the increasing availability of sensors and capturing devices, we can now actively record and leverage data from our daily activities to gain valuable insights and make informed decisions. PSA at its core formulates a combination of embodied cognition, situated analytics, and conversation analysis while exploiting the benefits of strategic immersion and sensemaking in immersive environments. To that end, we first developed a framework for embedding the individuals in the environment where the conversation originally occurred. Secondly, we conducted a pilot user study (n=12, protocol #STUDY2023-0018), to compare user experiences while exploring recorded conversations in Mixed Reality through the HoloLens2 device, and in Virtual Reality through the Quest2 device. Our proposed framework encompasses various stages such as tracking, data capturing, data cleaning, data synchronization, prototype building, and deploying the final product to end-user hardware. In the first part of the experiment, we used datasets consisting of seated participants (protocol #2022-0354). In the future, we will record and analyze datasets with standing and non-stationary participants (protocol #STUDY2023-0509) in two settings that would employ various collaboration profiles among the participants. Drawing from our experience during the preliminary user study and the feedback we received from the participants, we catalog our lessons learned and insights which can potentially drive advancements in embodied situated analytics and thereby enhance the conversation analysis pipeline.

PSA is an immersive MR/VR framework for experiencing and analyzing recorded conversations and events. We see two participants represented as virtual avatars engaged in a conversation.

The National Science Foundation has awarded EVL a Major Research Instrumentation (MRI) grant to build the Data Observation and Computation Collaboratory (DOCC) in the new Computer Design Research and Learning Center (CDRBC) building. The Data Observation and Computation Collaboratory (DOCC, &rsquo;the dock&rsquo;) is a much-needed visual data science instrument for UIC science and engineering research and research training. DOCC provides high-performance computing, advanced networking, high-speed data storage, interactive high-resolution displays and software and services for Artificial Intelligence / Machine Learning (AI/ML), data analytics, data simulations, visualization, and virtual-reality requirements. Given how varied modern data-science application requirements can be, DOCC is designed as a configurable, heterogeneous computing environment that prioritizes real-time, interactive, collaborative applications and remote data streaming, but can be scheduled off-hours for large, batch-mode processing. 
DOCC will empower users to work with their data and their colleagues in real-time, test codes, view a &rsquo;window in the oven&rsquo;to watch large simulations run, and simultaneously view results along with related data and ensemble runs on large display walls. DOCC has a visual front end that enables users to easily access familiar collaboration tools, scientific notebooks, AI/ML workflows, and popular visualization software. 
Alternatively, users can add new AI/ML models or create them from scratch. And because DOCC will be connected to the campus research network, data and/or computer codes can be ported to remote computer and cloud resources located on campus, regionally, nationally, or internationally. 
A room-sized instrument, DOCC will be located in the high-trafficked atrium of the new CDRLC, home to the UIC Computer Science Department, part of the College of Engineering, situated across from an auditorium and multi-purpose event space. This location will promote UIC data-science research initiatives and the instrument&rsquo;s collaboration potential. DOCC will also be used to conduct campus research meetings, programs and training initiatives.

Applications in immersive environments have gained popularity for training, learning, and recreational tasks. Due to the increasing availability of sensors and data-capturing devices, research is extending the use of immersive environments to support visual analytics processes, including sensemaking and strategic immersion for interaction and task completion. In this work, we propose Personal Situated Analytics (PSA) framework to embed users into recorded meetings with support for multiple degrees of immersion in the Reality-Virtuality spectrum. Our proposed framework encompasses various stages such as tracking, data capturing, data cleaning, data synchronization, prototype building, and deploying the final product to end-user hardware. We evaluate this framework on a data analysis scenario between human subjects and a conversational AI agent. Our pilot study (n=12) using this framework compares user experiences when using two different devices: Hololens2 and Quest2.

Using Personal Situated Analytics (PSA) to Interpret Recorded Meetings

Using immersive environments for training, education, and recreation is becoming increasingly popular among individuals. In recent years these environments have also been used to facilitate data analytics processes involving interaction and task completion. In this work, we discuss Personal Situated Analytics (PSA) a cross-platform framework to embed users into recorded conversations with support for multiple degrees of immersion in the Reality-Virtuality spectrum. Our development pipeline consisted of several stages: tracking, data capturing, data cleaning, data synchronization, prototype building, and deploying the final product to end-user hardware. We evaluate PSA by analyzing data from a recorded meeting involving human participants and a visual conversational AI agent. Our pilot study (n = 12) using this framework compares user experiences for MR and VR environments.

Friday 10/25/24, 1pm 
EVL Continuum (Room 2068 Engineering Research Facility) 
Abstract: 
Augmented reality (AR) has the potential to fundamentally change the way we interact with information. Direct perception of computer-generated graphics atop physical reality can afford hands-free access to contextual information on the fly. However, as users must interact with not only information on the display but also environmental changes in the real world, the traditional User-Centered Design (UCD) approaches that focus on human-computer interaction, may not always adequately address the dynamic nature of human-environment interaction. This seminar will introduce, Ecological Interface Design (EID), a new approach to the design and evaluation of AR interfaces to complement UCD. EID is a framework for interface design that respects dynamic, environmental constraints imposed on users&rsquo; behavior. EID addresses two questions for interface design; what information should be displayed (the content and structure of information that represent the physical reality of the work environment), and how that information should be presented (the perceptual forms of interface elements compatible with human information processing). The talk will start with the theoretical background of EID and show how this approach can benefit AR user interface design and evaluation with an example of an AR head-up display for vehicle drivers.

September 2023 marks the 50th anniversary of the Electronic Visualization Laboratory (EVL) at University of Illinois Chicago (UIC). EVL&rsquo;s introduction of the CAVE Automatic Virtual Environment in 1992, the first widely replicated, projection-based, walk-in, virtual-reality (VR) system in the world, put EVL at the forefront of collaborative, immersive data exploration and analytics. However, the journey did not begin then. Since its founding in 1973, EVL has been developing tools and techniques for real-time, interactive visualizations - pillars of VR. But EVL&rsquo;s culture is also relevant to its successes, as it has always been an interdisciplinary lab that fosters teamwork, where each person&rsquo;s expertise contributes to the development of the necessary tools, hardware, system software, applications, and human interface models to solve problems. Over the years, as multidisciplinary collaborations evolved and advanced scientific instruments and data resources were distributed globally, the need to access and share data and visualizations while working with colleagues, local and remote, synchronous and asynchronous, also became important fields of study. This paper is a retrospective of EVL&rsquo;s past 50 years that surveys the many networked, immersive, collaborative visualization and VR systems and applications it developed and deployed, as well as lessons learned and future plans.

The Data Observation and Computation Collaboratory (DOCC, &rsquo;dock&rsquo;) is a visual data science instrument for University of Illinois Chicago (UIC) science and engineering research and research training. Many UIC researchers are part of multi-disciplinary teams investigating and contributing to solutions for societal issues, in such fields as biology, cybersecurity, healthcare, manufacturing, urban sustainability, and cyber-physical systems (e.g., autonomous cars). DOCC is a digital &rsquo;Project Room&rsquo; that enables domain scientists and computer scientists to collaborate on real-world problems by providing them with high-performance computing, high-resolution displays, and sophisticated Artificial Intelligence (AI), data analytic, data simulation, image processing, visualization, and virtual-reality software and services. 
Societal challenges can only be addressed by research teams, with each contributing expertise in complementary areas. DOCC&rsquo;s Intellectual Merit is two-fold: it provides onsite computing with adequate support, and it provides collaboration software services. With respect to the former, DOCC is a configurable computing environment that prioritizes real-time, interactive, collaborative, data-intensive applications, but can be scheduled off-hours for batch-mode processing. Users can execute codes faster, apply more sophisticated analytics to large-scale problems, gain greater insights, and open new avenues of research. With respect to the latter, DOCC&rsquo;s collaboration software lets researchers either sit around one of DOCC&rsquo;s large tables and display walls or video-teleconference in while simultaneously sharing and interacting with their data on the large displays – which remote viewers can access online. 
To encourage adoption and ensure Broader Impact, DOCC has a visual front end, enabling users to easily access familiar collaboration tools, scientific notebooks, AI workflows, and popular visualization software. Alternatively, users can add new AI models or create them from scratch. And because DOCC is connected to the UIC research network, data and/or computer codes can be ported to remote computer and cloud resources located on campus, regionally, nationally, or internationally. DOCC personnel can assist new users make their applications more robust, dynamic and configurable. DOCC can transform scientific research, data exploration and discovery, recruit and retain new faculty, make cyberinfrastructure more accessible to students, and help educate the next-generation workforce. UIC is a Minority Serving Institution, a Hispanic Serving Institution and an Asian American and Native American Pacific Islander Serving Institution. 
DOCC and its associated data will remain active for at least three years after the completion of this project, as demand dictates. Software will be stored and archived via EVL&rsquo;s storage servers, as well as code repositories.
