The usability of an eye-gaze input system to aid interaction with computers for older computer users was investigated. The eye-gaze input system was developed using an eye-tracking system An experiment using the developed eye-gaze input system was conducted while systematically manipulating experimental conditions such as the moving distance, size of a target, and direction of movement in a pointing task The usability of the eye-gaze input was compared among three age groups (young, middle-aged, and older adults) and with that of a traditional PC mouse. The eye-gaze input system led to a faster pointing time as compared with mouse input, especially for older adults. This result demonstrates that an eye-gaze input system may be able to compensate for the declined motor functions of older adults when using mouse input.
