User Fatigue and Eye Controlled Technology
Computer Vision Syndrome (CVS), more commonly known as eye fatigue, is a problem often associated with regular computer use. For some users of eye controlled technology, the eye fatigue is an even greater problem. The eyes are used not only to observe and process information on screen and the user’s environment, but also to operate the computer instead of relying on a mouse, switch or keyboard. This can result in user fatigue, especially with new users of the technology. This research led to an analysis of several design elements through a series of surveys, interviews, and design prototype tests, coupled with literature reviews in both CVS and user interface design practices. This information was used to create a set of guidelines for user interface designers to refer to when developing applications for eye controlled technology.
