Abstract

The invention causes a panoramic view to be realistically displayed to a viewing audience. A fixed display device displays a portion of the panoramic view and a rotating support structure supports the viewing audience. The orientation of the portion of the panoramic view shown by the display device changes in coordination with the rotation of the support structure, while the viewing audience changes its viewing direction to continue looking at the display device. The characteristics of the system (in particular, the rotation of the support structure) are controlled so that the viewing audience is not conscious of the movement of the support structure, but thinks, instead, that the display device (and the displayed portion of the panoramic view) is moving about the support structure as the viewing audience changes its viewing direction. The invention can be implemented as a non-interactive system in which the system operates independently of the viewing audience. Alternatively, the invention can be implemented as an interactive system in which the orientation of the displayed portion of the panoramic view and the position of the support structure rotate in response to viewer input. The interactive system can be implemented either as a direct control system or a feedback control system.

Claims

1. A system for displaying a panoramic view to a viewing audience, comprising:

means for displaying a portion of the panoramic view that corresponds to a particular rotational orientation of the panoramic view, the means for displaying being fixed in position;

means for controlling the means for displaying so that various portions of the panoramic view can be displayed;

means for supporting the viewing audience so that the viewing audience can look at the means for displaying;

means for rotating the means for supporting so that the viewing audience must change viewing direction to continue looking at the means for displaying as the means for supporting rotates; and

means for synchronizing operation of the means for rotating and the means for controlling the means for displaying so that the means for supporting is rotated in a synchronous manner with the rotation of the orientation of the portion of the panoramic view displayed by the display device.

2. A system as in claim 1, wherein the means for rotating rotates the means for supporting with a rotational velocity having a magnitude such that, if the viewing audience continually changes its viewing direction so as to continually look at the means for displaying while the means for supporting is rotating, the viewing audience does not perceive the physical sensation of rotation of the means for supporting.

3. A system as in claim 2, wherein the rotational velocity is 1 rpm or less.

4. A system as in claim 1, wherein the means for supporting further comprises a platform for supporting one or more viewers.

5. A system as in claim 1, wherein the means for supporting further comprises a chair for supporting a viewer.

6. A system as in claim 1, wherein the means for supporting further comprises a support harness for supporting a viewer.
