Wearable display and methods for controlling same
First Claim
1. A device for assisting a computer user in interacting with a computer or like data processing device, comprising:
- a wearable display device coupled to said computer'"'"'s display output, said wearable display including an instantaneous viewing window;
a visual interface device resident on said computer, said visual interface device providing a virtual desktop whose size is larger than the instantaneous viewing window provided by said wearable display;
a tracking device for sensing motion of the wearable display device, converting said sensory input generated by said motion sensed into tracking data, and inputting said tracking data into said computer;
a magnification selection device responsive to said sensory input generated by said motion sensed into tracking data for selection of an enlargement factor applied to the enlarged data; and
,a signal processing device resident on said computer for interpreting said tracking data for purposes of determining which portion of the virtual desktop will be displayed within said instantaneous viewing window at a particular point in time,whereby the computer user can view any portion of the virtual desktop and control the magnification of the portion displayed in said instantaneous viewing window by controlling the position of the tracking device.

Abstract
A virtual computer monitor is described which enables instantaneous and intuitive visual access to large amounts of visual data by providing the user with a large display projected virtually in front of the user. The user wears a head-mounted display containing a head-tracker, which together allow the user to position an instantaneous viewport provided by the head-mounted display at any position within the large virtual display by turning to look in the desired direction. The instantaneous viewport further includes a mouse pointer, which may be positioned by turning the user'"'"'s head, and which may be further positioned using a mouse or analogous control device. A particular advantage of the virtual computer monitor is intuitive access to enlarged computer output for visually-impaired individuals.

17. A computer implemented method for assisting a user in the control and operation of a computer system having a wearable display device, the computer system being display driven in that a primary source of feedback for interacting with the computer system is visual feedback generated by the computer system, the visual feedback intended for display upon any display screen coupled with the computer system, the computer implemented method comprising the steps of:
-
equipping a user with a wearable display device coupled to a computer system; mapping visual feedback generated by the computer system into a virtual desktop suitable for display via the wearable display device; displaying a certain portion of the virtual desktop via the wearable display device; tracking movement of the wearable display device; and updating the displayed certain portion of the virtual desktop in a manner correlated to the tracked movement of the wearable display device, the updated characteristics including virtual position of the displayed certain portion and virtual magnification of the displayed certain portion. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
