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.
