A real-world-oriented database that consists of one s view is constructed by one s implicit behavior of watching objects. Digital Reminder provides a user with WYSIWYR- what-you-see-is-what-you-retrieve- based interaction for view image retrieval. WYSIWYR is a new framework in information retrieval. In retrieving image data in a database we generally enter a query by specifying one or more image attributes such as color or shape with a keyboard and or a pointing device. Unlike former image retrieval WYSIWYR framework identifies the user s current view of watching as a query condition and the user s behavior of watching an object is regarded as a trigger for the retrieval. Since the context of watching that is the type of visual information and gaze duration is also recognized as a view frame attributes VFA a more appropriate result is presented to the user. The result of performance evaluation showed that the view images similar to one s current view of gazing were ranked higher in the result of retrieval compared with the retrieval without VFAs.
