Abstract: 
When interacting with large displays, virtual reality, or augmented reality, people often use mid-air gestures. During these touchless interactions, they may need to alternate between hands or use both hands simultaneously. Most individuals have a hand preference, and preferred and non-preferred hands in lateralized individuals perform differently due to cerebral hemispheric specialization. For example, in right-handed individuals, the right hand is typically better at sequential motor tasks - those requiring (sensory) feedback control - whereas the left hand is better at parallel processing or open-loop behavior. In this thesis, we examine how lateral asymmetry impacts user performance in touchless input. My research provides an empirical investigation to characterize touchless performance when using preferred, non-preferred, and both hands. It explores binding the related tasks sequentially and in parallel, as well as different phrase structures, considering how much muscular tension is involved. 
In this work, we compared preferred and non-preferred hand performance in simple and compound tasks, such as pointing and select-and-dragging, respectively. In right-handed individuals, we did not find any significant performance differences between their preferred and non-preferred hands in touchless pointing or dragging. However, between-hand performance differences were significant when using mouse and stylus input. 
Additionally, we studied how phrasing with both hands can support volumetric multi-selection in touchless input. We present an empirical comparison of mid-air multi-selection techniques spanning dominant and non-dominant hand actions. The symmetric-synchronous and high-tension asymmetric-asynchronous bimanual techniques were not significantly different in terms of efficiency, and accuracy for within-reach targets. Furthermore, there were no significant differences between low and high-tension asymmetric-asynchronous bimanual techniques. The symmetric-synchronous bimanual technique was most preferred by users. 
Lastly, we explored how different phrase structures in bimanual phrasing impact compound task performance, such as touchless multi-selection and manipulation (e.g., drag-and-drop). Our findings revealed that while accuracy remained consistent across different tension levels, higher tension led to faster completion times through continuous gesture engagement. Interestingly, participants preferred half-tension phrasing for its ergonomic balance, as it minimized fatigue without compromising efficiency. These empirical findings can inform the design of future bimanual and multimodal interaction techniques involving touchless input.

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.

AI Impact Symposium

EVL undergraduate researcher Athena Angara discussed her summer internship project with Argonne Leadership Computing Facility (ALCF), &ldquo;Tele-robotics to Tele-autonomous Robotics for Isotope Production,&rdquo; during NVIDIA&rsquo;s weekly livestream, Community Spotlight: Unlocking Physical AI with Isaac Sim and OpenUSD. 
Angara is a senior studying data science. She spent her summer at the ALCF working on a DOE-funded project that leveraged virtual reality and augmented reality to create digital twins of critical components of robotic arms. Using Unreal Engine 5 and NVIDIA&rsquo;s Unity, Omniverse, and Isaac Sim, Angara developed an immersive display system with real-time, low latency, and high spatial resolution for remote control processes. She also converted data to ensure accurate representations between these digital platforms. 
NVIDIA&rsquo;s Omniverse is a real-time 3D graphics collaboration platform. It has been used for applications in the visual effects and &ldquo;digital twin&rdquo; industrial simulation industries. Omniverse makes extensive use of the Universal Scene Description format.

Abstract 
The potential of Immersive Analytics approaches to enhance how humans understand and interact with data has attracted the attention of visualization researchers for decades, as is well illustrated by the work done at the EVL. Quick technological advances in head-mounted displays over the last years led to devices such as Meta Quest 3 and Apple Vision Pro, bringing those techniques closer to widespread adoption. However, the design space for Immersive Analytics applications is vast, and it is crucial to understand the advantages and disadvantages of alternative designs. Over the last eight years, during the development of my Master&rsquo;s and PhD dissertations, I have studied the design of HMD-based environments for Immersive Analytics, investigating different data exploration metaphors, frames of reference, and modes of interaction. As a result, I have also proposed a series of ideas to reimagine existing visualization applications to take advantage of the benefits of immersion. In this talk, I will present an overview of my research work and my current ideas on this topic, with a deeper focus on my most recent paper, &ldquo;Reimagining TaxiVis,&rdquo; which I believe sets forth concepts that can be useful for other applications.

Andrew Wentzel presents his research entitled &ldquo;Digital Twins Visualization&rdquo; at the IEEE VIS2024 Conference at 3:30 (4:30 EDT) October 17, 2024. 
Abstract: 
Digital twin models are of high interest to Head and Neck Cancer (HNC) oncologists, who have to navigate a series of complex treatment decisions that weigh the efficacy of tumor control against toxicity and mortality risks. Evaluating individual risk profiles necessitates a deeper understanding of the interplay between different factors such as patient health, spatial tumor location and spread, and risk of subsequent toxicities that can not be adequately captured through simple heuristics. To support clinicians in better understanding tradeoffs when deciding on treatment courses, we developed DITTO, a digital-twin and visual computing system that allows clinicians to analyze detailed risk profiles for each patient, and decide on a treatment plan. DITTO relies on a sequential Deep Reinforcement Learning digital twin (DT) to deliver personalized risk of both long-term and short-term disease outcome and toxicity risk for HNC patients. Based on a participatory collaborative design alongside oncologists, we also implement several visual explainability methods to promote clinical trust and encourage healthy skepticism when using our system. We evaluate the efficacy of DITTO through quantitative evaluation of performance and case studies with qualitative feedback. Finally, we discuss design lessons for developing clinical visual XAI applications for clinical end users.
