The present invention is a system that allows a user to physically rotate a three-dimensional volumetric display enclosure with a corresponding rotation of the display contents. The rotation of the enclosure is sampled with an encoder and the display is virtually rotated by a computer maintaining the scene by an amount corresponding to the physical rotation before being rendered. This allows the user to remain in one position while viewing different parts of the displayed scene corresponding to different viewpoints. The display contents can be rotated in direct correspondence with the display enclosure or with a gain (positive or negative) that accelerates the rotation of the contents with respect to the physical rotation of the enclosure. Any display widgets in the scene, such as a virtual keyboard, can be maintained stationary with respect to the user while scene contents rotate by applying a negative rotational gain to the widgets. The rotation can also be controlled by a time value such that the rotation continues until a specified time is reached or expires.

A method of producing multiple three-dimensional images to create an optical illusion of movement, comprising the steps of: (a) energizing particles suspended within a volumetric display sequentially along the length and width of the volumetric display through projection of electromagnetic energy of one or more wavelengths, the energized particles forming a two-dimensional image; b. intersecting the energized particles through projection of electromagnetic energy of one or more wavelengths along the depth of the volumetric display; c. synchronizing the projection of electromagnetic energy along the length and width of the volumetric display with the projection of electromagnetic energy along the depth of the volumetric display for a pre-determined length of time forming an illuminated three-dimensional image; and d. repeating steps a, b and c for each of the plurality of three-dimensional images using a predetermined scanning sequence to create the optical illusion of movement.

An improved method and/or system to generate depth data for a 2D image for subsequent display on an MLD or other volumetric display. A multi-layered display (MLD) includes first and second display layers with one said display layer overlapping the other said display layer. The first display layer displays a first image and a second display layer displays a second image. The second image is synchronised with said first image such that an alteration of at least one image property of said first age triggers an alteration of at least one image property of said second image.

The present invention is a system that creates a volumetric display and a user controllable volumetric pointer within the volumetric display. The user can point by aiming a beam which is vector, planar or tangent based, positioning a device in three-dimensions in association with the display, touching a digitizing surface of the display enclosure or otherwise inputting position coordinates. The cursor can take a number of different forms including a ray, a point, a volume and a plane. The ray can include a ring, a bead, a segmented wand, a cone and a cylinder. The user designates an input position and the system maps the input position to a 3D cursor position within the volumetric display. The system also determines whether any object has been designated by the cursor by determining whether the object is within a region of influence of the cursor. The system also performs any function activated in association with the designation.

The present invention is a system that allows a number of 3D volumetric display or output configurations, such as dome, cubical and cylindrical volumetric displays, to interact with a number of different input configurations, such as a three-dimensional position sensing system having a volume sensing field, a planar position sensing system having a digitizing tablet, and a non-planar position sensing system having a sensing grid formed on a dome. The user interacts via the input configurations, such as by moving a digitizing stylus on the sensing grid formed on the dome enclosure surface. This interaction affects the content of the volumetric display by mapping positions and corresponding vectors of the stylus to a moving cursor within the 3D display space of the volumetric display that is offset from a tip of the stylus along the vector.

The invention relates to a method of manipulating the visibility of image elements on the screens of a multi-screen display. In particular, methods of maximising the visibility of selected target image elements are identified.

The present invention is a system that places 2D user interface widgets in optimal positions in a 3D volumetric display where they can be easily used based on the knowledge user have about traditional 2D display systems. The widgets are placed on a shell or outer edge surface of a volumetric display, in a ring around the outside bottom of the display, in a vertical or horizontal plane within the display and/or responsive to the users focus of attention. Virtual 2D widgets are mapped to volumetric voxels of the 3D display system. This mapping includes any mapping between a 2D representation or virtual display map of the widget to the corresponding voxels. For example, a 2D texture map of the widget image may be mapped into voxels. Control actions in the 3D volume initiated by conventional control devices, such as a mouse or a touch sensitive dome enclosure surface, are mapped to controls of the widgets and appropriate control functions are performed.

A volumetric imaging apparatus has a volumetric image generator with a light source, a light modulator, and a display surface. The volumetric image generator is energizable to form, on the display surface, an image over a range of focal positions at the entrance pupil of an optical system. The optical system is disposed to direct light from the image to a one-dimensional pupil expander. A combiner surface is disposed in the path of output light from the pupil expander for displaying the volumetric image.
