Eye-based Human-Computer Interaction: HCI is developed in partcular for disabled and elderly persons. Users can key-in the key in concern to their computer by using only their eyes. Using Near Infared: NIR camera with NIR light source mounted on their glass, users' eye images are acquired. The line of sight vector, then can be estimated through image processing. Therefore, the location at which users is looking can be estimated. The moving keyboard proposed here can be moved to the right/left/above/below directions from the center of the enlarged key location when users are looking at the displayed enlarged right/left/above/below keys. It is easy to select the specific enlarged keys with 100% of success rate. It can be done within 0.7 second. Therefore, key-in can be done perfectly. This Eyes-based HCI can be applicable to Electric Wheel Chair: EWC control. When users on their EWC are looking at left and right, then EWC is turned left and right while EWC moves forward when users are looking forward (the center). It also is possible to phoning, watching TV, web search etc. with their eyes only when they use the proposed eye-based HCI. A variety of applications of the proposed eye-based HCI will be presented.
