Abstract

This invention relates to a method and apparatus for viewing of a panorama or large portion thereof by selectively displaying a portion thereof on a video display device or other means and in a manner that forces the user to change his own orientation to vary the portion of the panorama viewed. Such a method and apparatus coordinates the user'"'"'s normal feedback responses associated with changing orientation to changes in the portion of the panorama viewed. In a preferred embodiment, a simple apparatus for allowing a user or users to view the recorded panorama is disclosed.

Claims

1. A system for viewing of a real panoramic image comprising:

frame buffer means for digitally storing the real panoramic image, and

means for viewing of a selected segment of the stored real panoramic image, said viewing means including user controlled movable viewing screen means, said movable viewing screen means displaying the selected segment of the stored real panoramic image, said viewing means having sensing means for sensing rotational movement of said viewing means and in accordance with the sensed rotational movement adjusting the selected segment of the stored real panoramic image stored in the frame buffer means, whereby the user selectively moves said viewing screen means to vary the selected segment of the stored real panoramic image displayed by said viewing screen means.

2. A system as claimed in claim 1 wherein said viewing screen means is a video display terminal mounted on a rotatable base and including handle means for rotating said rotatable base about a vertical axis, said rotatable base including means for sensing the rotational position of said base which forms part of said sensing means for sensing rotational movement of said viewing means.

3. A system as claimed in claim 1 wherein said user controlled viewing means is a pair of video glasses.

4. A system as claimed in claim 1 wherein said viewing screen means is suitable for viewing by a plurality of users simultaneously.

5. A system as claimed in claim 4 wherein said sensing means for sensing rotational movement of said viewing means includes an optical shaft encoder which is rotated with rotation of said base and produces an output signal for varying said selected segment of the real panoramic image viewed.

6. A video display viewing table comprising a base portion and a top section rotatable relative to said base portion and supported relative to said base portion by a shaft fixed to rotate with said top section and bearingly supported in said base portion, said shaft driving an optical shaft encoder whereby rotation of said top section relative to said base portion can be sensed and estimated by said optical shaft encoder.

7. A video display viewing table as claimed in claim 6 wherein said shaft includes a further pulley and belt driving a larger rotation limiting pulley having a stop surface thereon which cooperates with a fixed stop surface secured to said base portion whereby after a predetermined rotation of said top portion relative to said base portion further rotation in the same direction is opposed by engagement of said stop surfaces.

8. A video display viewing table as claimed in claim 7 wherein said shaft is hollow.

9. A video display viewing table as claimed in claim 8 including a tension idler disposed between said rotation limiting pulley and said shaft to tighten the pulley belt therebetween while allowing some slippage therebetween when said locking surfaces are in engagement.
