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

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.

• G02B 30/56 - Optical systems or apparatus for producing three-dimensional [3D] effects, e.g. stereoscopic images the image being built up from image elements distributed over a 3D volume, e.g. voxels by projecting aerial or floating images
