Abstract: There is described a method for controlling, in a display, a virtual image of a displaying object for which displaying is controllable. The method comprises providing a curved mirrored surface opposing the displaying object to produce the virtual image. The location of an observer is determined, with respect to the curved mirrored surface. A position of the virtual image can then be determined for the observer at the location, wherein this virtual image provides at least one of parallax and a stereoscopic depth cue. The displaying object is controlled to produce the virtual image as determined.

Abstract: There is described a method for operating an immersive display. A plurality of objects are displayed to a viewer within an immersive environment. A computer system controls an image rendering of the immersive environment and a size, location and appearance of each one of the plurality of objects. The controls can be made by the operating system adapted to this task. Such controls provide a monocular psychological depth cue to the viewer for each one of the plurality of objects.

Abstract: A multi-sensor omnidirectional camera or cameras where the virtual center of projections of the cameras are controlled using movable reflective surfaces. The virtual center of projections can be placed in closer proximity to one another than would otherwise be possible due to physical space limitations. In addition, the reflective surfaces can be controlled in such a way as to offset or compensate for different camera displacements and rotations in order to achieve a configuration where high fidelity to a natural field-of-view is attained. This proves beneficial in virtual reality applications where a high level of visual fidelity is necessary for full immersion.

Abstract: There is described a display apparatus for producing an aerial image of an object. The display apparatus comprises a display acting as the object to be imaged. A first beam splitter or reflective polarizer receives light from the display and redirects at least a portion of the light to one or two retroreflectors. Lens arrays can be added onto the retroreflector(s) to reduce blur. A second beam splitter or reflective polarizer receives the light from the retroreflector(s) and produces the aerial image. The second beam splitter or reflective polarizer is aligned with a point of view of the viewer, thus defining a horizon of the field of view. An opaque surface extends below the horizon, and the first beam splitter or reflective polarizer, the first retroreflective sheeting and the display are located under the surface and therefore below the horizon, thus keeping the over-the-head space free of equipment.
