Headset computer with head tracking input used for inertial control
First Claim
1. A method of controlling document navigation in a headset computer, the method comprising:
- overlaying a navigator tool on a subject document displayed on the headset computer being worn by a user;
indicating, at the navigator tool and in response to received head movement of the user at the headset computer, a representation of the received head movement; and
panning the subject document at a speed and in a direction based on the received head movement,wherein overlaying the navigator tool includes overlaying an inner boundary and an outer boundary, the inner boundary and outer boundary being concentric circles having different diameters and further overlaying a pointer configured to move within the inner boundary and the outer boundary;
wherein indicating the representation of the received head movement includes indicating the representation by positioning the pointer with respect to the origin of the two circles;
wherein panning the subject document includes panning the subject document at the speed based on a distance from the origin minus a radius of the inner boundary.

Abstract
A Head-tracker is built into a headset computer as a user input device. A user interface navigation tool utilizes the head tracking but with inertial control. The navigation tool is formed of two different sized circles concentrically depicted, and a pointer. The pointer is moveable within the two circles defining inner and outer boundaries. The pointer represents user'"'"'s head position and movement sensed by the head tracker. The HSC displays a document and pans (navigates) the document as a function of user head movement sensed by the head tracker and illustrated by the navigation tool. The direction of movement of the pointer depicted in the navigation tool defines pan direction of the displayed document. Pan speed of the displayed document is defined based on position of the pointer, with respect to the inner and outer circle boundaries in the navigation tool.
