Enhancing a CAVE with Eye Tracking System for Human-Computer Interaction Research in 3D Visualization
Abstract
The objective of this award was to purchase and install two ISCAN Inc. Eye Tracking Systems and associated equipment to create a unique set-up for research in fully immersive virtual environments (VEs), specifically a CAVE. To our knowledge, the Virginia Tech installation is the first CAVE in the world to have eye-tracking technology incorporated into it We purchased two ISCAN Inc. Eye Tracking Systems, including calibrator, headband-mounted eye imaging system, dual video monitors, line of sight scene imaging system, magnetic head tracker, and appropriate software. The Eye Tracking Systems collect three-dimensional measurements of a user's eye inside the CAVE. These measurements are performed by calculating the direction of a line called the line-of-sight, which originates from a user's eye and extends into the environment in the direction of the pupil's gaze. Intersections between the line-of-sight and visible objects in the VE are computed, and the results are stored to a log file on disk. This work has the potential to lead to strong analytical assessment methodologies for VEs (see Conclusions above) that can reduce the effort and costs of usability evaluations of VEs.
