EyePrint: support of document browsing with eye gaze trace

Current digital documents provide few traces to help user browsing. This makes document browsing difficult, and we sometimes feel it is hard to keep track of all of the information. To overcome this problem, this paper proposes a method of creating traces on digital documents. The method, called EyePrint, generates a trace from the user's eye gaze in order to support the browsing of digital document. Traces are presented as highlighted areas on a document, which become visual cues for accessing previously visited documents. Traces also become document attributes that can be used to access and search the document. A prototype system that works with a gaze tracking system is developed. The result of a user study confirms the usefulness of the traces in digital document browsing.
