This project is designed to undertake an investigation of human eye movement within stereoscopic displays, with the goal of improving the perceptual effectiveness of these displays for visualization. While numerous studies have looked at eye motion for conventional displays, there has been very little work on stereo displays. The challenge and the opportunity for eye tracking in stereo displays is that both eyes can be tracked, yielding information on both gaze position on the screen and eye vergence. This will allow the estimation of where the subject is fixating in three dimensional space, not just in screen space. Three-dimensional eye tracking will illuminate how a stereoscopic display is scanned, allowing direct observation of strategies used to explore and interpret information in these displays. This in turn will provide important information to the designers of such displays to increase their effectiveness in transmitting information. Experiments are being done on a unique Wheatstone stereoscope augmented with eye trackers, on an autostereoscopic display, and on a conventional active stereo display.
