Abstract:
Video eye-tracking appears to have great utility in the investigation and assessment of visuospatial neglect, and it may also have important benefits to intervention. Applications include the use of desktop eye-tracking to quantify neglect and its sensitivity to social cues, acquisition of eye-tracking data during performance of clinical and experimental assessment tasks, and trials of a wireless system to track the gaze of patients carrying out activities of daily living. Displays that provide differential feedback contingent on gaze locus may be particularly applicable to computer-aided training. If eye-tracking proves to be useful for monitoring and for automatic delivery of training, it can eventually be incorporated into telerehabilitation.
