Hands-Free Point-and-Click Computer Control Device Within a Moving Vehicle

"The purpose of this project is to develop a novel human-computer interaction protocol called EvPac, a combined eye and voice-operated system to perform computer point-and-click operations in a moving vehicle. To point and click an icon with EvPac, theoperator simply performs the natural actions of looking at the icon he wishes to activate and speaking a key command word such as "click." An eyetracker measures the user's gazepoint on the computer screen and a speech recognition system detects theverbal commands. No hand activity is involved.EvPac will replace the mouse and trackball, which are unwieldy in a moving vehicle environment where it is difficult to maintain steady hand movements. EvPac also provides a simplified alternative to voice-only interfaces; EvPac uses only a small set ofgeneric command words that are applicable to all icons, while voice-only approaches in many cases require the user to memorize virtually hundreds of specific verbal commands for the application's different icons."
