Students are introduced to the history, development, and design features of Eye Tracking. The lab will specifically focus on the application of eye tracking in assistive technology that helps people with physical limitations. Students will make a mechanical model of an eye to understand how the computer sees the eye when performing eye tracking. Students will also make sketches of the eye/eye tracker’s geometry and derive trigonometric equations used to measure the eye’s pointing direction. Finally, students will work through a series of mazes using eye gaze to apply the ideas behind Life Drive into the classroom.
