TacTile is a multi-touch 52-inch LCD tabletop display design to support collaborative applications through a highly intuitive, multi-user touch interface. Users can pan, zoom, and interact with highly detailed imagery and applications, in real-time, and with improved resolution and accuracy over displays based on video projection. TacTile targets scientific researchers who require high resolution to gain insight into complex datasets, and address a broad range of e-science application areas, as well as public institutions such as museums, where such systems can appeal to a broad range of participants.
The user interface relies on touch to control application navigation. The technique used to detect the users’ fingertips is FTIR (frustrated total internal reflection), which uses infrared (IR) cameras and light refraction. Tracking the fingertips is achieved through a combination of established image processing software and EVL-developed custom software.
TacTile debuted at the SC08 Convention in Austin, TX the week of November 17th 2008.
