Head Tracking Based Gesture Control Techniques For Head Mounted Displays

Abstract

A head gesture-based recognition system in Headset Computers (HSC) is disclosed. Notification dialogue boxes can be acknowledged by head nodding or ticking movement in the user interface. Question dialog boxes can be assured by head nods or head shakes in the user interface. Head swiping is also a recognizable form of user input through a head tracker of the HSC. Progress indicators and other visual display feedback are utilized.

What is claimed is: 
     
         1 . A headset computer system, comprising:
 a headworn display unit;   an interface configured to couple an external digital processor to the display unit; and   a head tracker operatively coupled to the display unit and processor, the processor configured to be responsive to any one of a set of predefined user head gestures detected by the head tracker for making user selections.
