Abstract By linking a Micromeasurements binocular eye-tracker to an IBM-compatible PC we have developed a system to control computers by eye. Basically, 'mouse' commands are emulated: the cursor goes to where the person is looking on the screen and a menu-item is selected by either staring at it ('dwell') or by winking one eye ('wink'). In this study we have compared these two protocols by examining selection performance. Three subjects selected four different sized screen 'buttons' (representing the different sized targets of a 'Windows' interface) using three different dwell times and using a wink protocol. Performance was quantified in terms of selection speed and error rate. Learning effects were negligible after about 60 trials, by which time the number of incorrect selections had stabilised. Overall neither protocol was clearly superior, and we conclude that the appropriate selection method will be task-dependent.
