EyeTalk® is a software technology that integrates voice recognition and eye-tracking to control a computer interface without using the hands.

Eye-tracking, to compute the user’s point-of-gaze on a computer screen, is helpful in determining the object of interest such as a file or program. Voice commands provide additional context about what the user wishes to accomplish. For example, by visually acquiring a program icon, and then uttering “open” or “start,” the user can convey his/her intent to start a particular program. If this were to be accomplished by voice alone, it would be necessary to utter a very specific command, such as “open the word processing program.” Not only is such a command relatively difficult to remember, it may tax the speech recognition program’s ability to reliably parse the user’s command. Combining eye and voice simplifies the task of inferring a user’s intent to accomplish his/her goal.
