Abstract: To improve the accuracy and efficiency of eye tracking on mobile device and to reduce the cost,a gaze recall method as a complementation for eye movement data computing on mobile device was proposed.In this method,crowdsourcing technique was applied to distribute gaze recall tasks in crowd sensing environment,and task recommendation algorithm based on context-aware service was used to improve the gaze recall accuracy.A prototype system for gaze recall on mobile device was implemented,and the result of user testing showed that the recalled gaze data were very similar to gaze data from real eye tracker,which could validate the feasibility and effect of the proposed method.

Key words: eye tracking;gaze recall, visual attention, crowdsourcing, context-aware service, human-computer interaction
