Portable display and methods of controlling same
First Claim
1. A device for assisting a computer user in interacting with a computer or like data processing device, comprising:
- a portable display device coupled to said computer'"'"'s display output, said portable 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 portable display;
a tracking device for sensing motion of the portable display device, converting a sensory input generated by said motion sensed into tracking data, and inputting said tracking data into said computer;
a virtual desktop navigation device responsive to said sensory input generated by said motion sensed into tracking data, said virtual desktop navigation device useful for assisting said computer user in navigating said virtual desktop; 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.

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.

2. A computer implemented method for assisting a user in the control and operation of a computer system having a portable 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 portable display device coupled to a computer system;
mapping visual feedback generated by the computer system into a virtual desktop suitable for display via the portable display device;
displaying a certain portion of the virtual desktop via the portable display device;
tracking movement of the portable display device; and
updating the displayed certain portion of the virtual desktop in a manner correlated to the tracked movement of the portable display device, the updated characteristics including virtual position of the displayed certain portion.
-
-
3. A computer implemented method as recited in claim 2 wherein the step of tracking movement of the portable display device includes the sub-step of distinguishing a specific abrupt movement of the portable display device from other movements.
-
4. A computer implemented method as recited in claim 3 wherein step of tracking movement of the portable display device further includes the sub-step of performing a computer executable command corresponding to the specific abrupt movement of the portable device.
-
5. A computer implemented method as recited in claim 4 wherein the computer executable command corresponding to the specific abrupt movement of the portable device is a navigation command.
-
6. A computer implemented method as recited in claim 2 wherein the visual feedback generated by the computer system includes multiple application windows.
-
7. A computer implemented method as recited in claim 6 wherein a first window of the multiple application windows corresponds to a first application executing upon the computer system.
-
8. A computer implemented method as recited in claim 7 wherein the first application executing upon the computer system is a content providing application.
-
9. A computer implemented method as recited in claim 8 wherein the content providing application enables navigation through a content document via user movement of the portable display device.
-
10. A computer implemented method as recited in claim 7 further comprising the steps of:

receiving information from a remote source; and
displaying with in a first window of the multiple application windows at least a portion of the information received from a remote source.
-
-
11. A computer implemented method as recited in claim 10 wherein a second window of the multiple application windows corresponds to an application program executing upon the computer system.
-
12. A computer implemented method for assisting a user in the control and operation of a computer system having a portable 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 portable display device coupled to a computer system;
mapping visual feedback generated by the computer system into a virtual desktop suitable for display via the portable display device;
displaying a certain portion of the virtual desktop via the portable display device;
tracking movement of the portable display device;
updating the displayed certain portion of the virtual desktop in a manner correlated to the tracked movement of the portable display device;
receiving information from a remote source; and
displaying at least a portion of the information received from a remote source.
-
-
13. A computer implemented method as recited in claim 12 further comprising the step of displaying a pointer within the certain portion of the virtual desktop.
-
14. A computer implemented method as recited in claim 12 wherein the step of tracking movement of the portable display device includes the sub-step of distinguishing a specific abrupt movement of the portable display device from other movements.
-
15. A computer system particularly well-suited for portability, 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 a display screen coupled with the computer system, the computer system comprising:
