Intelligent user mode selection in an eye-tracking system
First Claim
1. A personal computer system comprising:
- a visual display;
an imaging device adapted to provide eye-tracking data by imaging at least one eye of a viewer of the visual display and to process said eye-tracking data; and
an identifying device adapted to recognize the viewer with reference to one of a plurality of predefined personal profiles and to sense a recognized viewer'"'"'s actual viewing condition,wherein the imaging device is selectively operable in one of a plurality of personalized active sub-modes associated with said personal profiles and further in one of a plurality of sub-profile modes, said plurality of sub-profile modes being hierarchically defined as children of a personalized sub-mode, and said one of a plurality of sub-profile modes being associated with said actual viewing condition.

Abstract
A personal computer system comprises a visual display, an imaging device adapted to provide eye-tracking data by imaging at least one eye of a viewer of the visual display, and identifying means for recognizing the viewer with reference to one of a plurality of predefined personal profiles. The personal computer system further comprises an eye-tracking processor for processing the eye-tracking data. According to the invention, the eye-tracking processor is selectively operable in one of a plurality of personalized active sub-modes associated with said personal profiles. The sub-modes may differ with regard to eye-tracking related or power-management related settings. Further, the identifying means may sense an identified viewer'"'"'s actual viewing condition (e.g., use of viewing aids or wearing of garments), wherein the imaging device is further operable in a sub profile mode associated with the determined actual viewing condition.

12. A method in a personal computer system comprising:
-
a visual display; an imaging device adapted to provide eye-tracking data by imaging at least one eye of a viewer of the visual display and to process said eye-tracking data, wherein the imaging device is selectively operable in one of a plurality of personalized active sub-modes and further in a sub-profile mode associated with said actual viewing condition; an identifying device for recognizing the viewer with reference to one of a plurality of predefined personal profiles, said method comprising; recognizing, using the first identifying device, a viewer by comparing viewer-related data with predefined personal profiles and selecting a best matching personal profile; sensing the recognized viewer'"'"'s actual viewing condition; and operating the imaging device in a sub-mode associated with said best matching personal profile and further in one of a plurality of sub-profile modes, said plurality of sub-profile modes being hierarchically defined as children of a personalized sub-mode, and said one of a plurality of sub-profile modes being associated with said actual viewing condition. - View Dependent Claims (13)
