Abstract
A method includes determining one or more controlled viewpoints of a multi-user display which includes a pixelated array and a directional multiplexer, and for each viewpoint of the one or more controlled viewpoints, determining first content to be displayed to the controlled viewpoint according to a visibility criterion. The method further includes, for each viewpoint of the one or more controlled viewpoints, determining a first subset of pixels of the pixelated array whose visibility from the controlled viewpoint satisfies the visibility criterion, and rendering the first content to be displayed on the first subset of pixels of the pixelated array.
Claims20
A method, comprising:
- at a multi-user display comprising a pixelated array and a directional multiplexer, determining one or more controlled viewpoints of the multi-user display;
- for each viewpoint of the one or more controlled viewpoints, determining first content to be displayed to the controlled viewpoint according to a visibility criterion;
- for each viewpoint of the one or more controlled viewpoints, determining a first subset of pixels of the pixelated array whose visibility from the controlled viewpoint satisfies the visibility criterion;
- and
- rendering the first content to be displayed on the first subset of pixels of the pixelated array,
- wherein each controlled viewpoint of the one or more controlled viewpoints comprises a point in a field of view of the multi-user display within a range of viewing angles and within a range of distances from the multi-user display.
A multi-user display comprising:
- a pixelated array;
- a directional multiplexer;
- and
- control logic configured to:
- determine one or more controlled viewpoints of the multi-user display,
- for each viewpoint of the one or more controlled viewpoints, determine first content to be displayed to the controlled viewpoint according to a visibility criterion,
- for each viewpoint of the one or more controlled viewpoints, determine a first subset of pixels of the pixelated array whose visibility from the controlled viewpoint satisfies the visibility criterion, and
- render the first content to be displayed on the first subset of pixels of the pixelated array,
- wherein each controlled viewpoint of the one or more controlled viewpoints comprises a point in a field of view of the multi-user display within a range of viewing angles and a range of distances from the multi-user display.
A non-transitory computer-readable medium containing instructions, which when executed by a processor, cause a multi-user display to:
- at the multi-user display comprising a pixelated array and a directional multiplexer, determine one or more controlled viewpoints of the multi-user display;
- for each viewpoint of the one or more controlled viewpoints, determine first content to be displayed to the controlled viewpoint according to a visibility criterion;
- for each viewpoint of the one or more controlled viewpoints, determine a first subset of pixels of the pixelated array whose visibility from the controlled viewpoint satisfies the visibility criterion;
- and
- render the first content to be displayed on the first subset of pixels of the pixelated array,
- wherein each controlled viewpoint of the one or more controlled viewpoints comprises a point in a field of view of the multi-user display within a range of viewing angles and within a range of distances from the multi-user display.
