EXPLORING EYE RESPONSIVE CONTROL - FROM A HEAD MOUNTED TO A REMOTE SYSTEM

摘要

The Attention Responsive Technology (ART) system is designed to enable control of the environment by individuals for whom movement is difficult or undesirable. This paper reports additional development of the ART system through replacing its initial head-mounted eye-tracking technology with a remotely mounted tracking system. The new system can release the user from the need to wear any head-mounted equipment, thus improving user comfort and acceptability. Instead, eye tracking cameras and the scene camera are situated in a fixed position some small distance from the user; these then allow tracking of the user's eye gaze and field of view, respectively. This system would suit many situations in which the user remains seated, for example, in a wheelchair or before a workstation onto which the cameras can be mounted.
