1. A computer controlled method for assisting a user of a computer to reestablish a lost context;
- said computer having a display device, and a gaze-tracking device;
said gaze-tracking device for determining a gaze position on said display device;
said computer controlled method comprising the steps of;
(a) monitoring said gaze position to track a current context within an active area of said display device;
(b) detecting a break of attention from said active area and saving said current context at the time of said break of attention as said lost context;
(c) restoring said lost context; and
(d) indicating said lost context to said user by applying an indicator to said lost context.

8. An information presentation apparatus configured to assist a user of a computer to reestablish a lost context;
- said apparatus having a central processor unit, a memory, a display device, and a gaze-tracking device for determining a gaze position on said display device;
said apparatus comprising;a monitor mechanism configured to monitor said gaze position to track a current context within an active area of said display device; a first detection mechanism cooperating with said monitor mechanism, configured to detect a break of attention from said active area;
said first detection mechanism also configured to save said current context at the time of said break of attention as said lost context;a second detection mechanism also cooperating with said monitor mechanism configured to detect when said gaze position enters a target area on said display device;
said target area having said lost context;a restoration mechanism configured to restore said lost context in said target area responsive to said second detection mechanism; and an indication mechanism configured to indicate said lost context to said user by applying an indicator to said lost context on said display device. - View Dependent Claims (9, 10, 11, 12, 13)
