  • Patent number: 7138963
    Abstract: The invention is a method for displaying otherwise unseen objects and other data using augmented reality (the mixing of real view with computer generated imagery). The method uses a motorized camera mount that can report the position of a camera on that mount back to a computer. With knowledge of where the camera is looking, and the size of its field of view, the computer can precisely overlay computer-generated imagery onto the video image produced by the camera. The method may be used to present to a user such items as existing weather conditions, hazards, or other data, and presents this information to the user by combining the computer generated images with the user's real environment. These images are presented in such a way as to display relevant location and properties of the object to the system user.

  • Patent number: 7119762
    Abstract: Alphanumeric images are displayed in common view in one color on a background of a different color using a liquid crystal projection device. The two colors are sufficiently similar so they are not distinguished by the unaided eye of the viewer. A color selective material in the form of glasses is provided to a subclass of the viewers in the audience to enable these viewers to distinguish the alphanumeric subtitles from the background. This material extinguishes either the alphanumeric images or the background, thereby either providing darkened letters on a light background or light letters on a darkened background. The projection and viewing apparatus can be utilized as a motion picture closed captioning system for a mixed audience of hearing impaired and non hearing impaired individuals to permit the hearing impaired to view the subtitles while those individuals not wearing such wavelength selective glasses would not see the subtitles.

  • Patent number: 7098872
    Abstract: A process and system for interactively displaying large (more than 1 million voxels) volumetric 3D images utilizing a sequence of helical slices of a 3D data set to generate a series of 2D images on a reflective surface of a light modulator. The series of 2D images generated on the light modulator are projected into a volumetric 3D-space display using an illumination light source and projection optics. Voxels in 3D space are illuminated for each 2D projected image, each voxel being located at its corresponding spatial location. A pulse from a wireless pulsed laser pointer forms a 3D bright voxel within the display volume. The pulse signal is synchronized with the rotating helix, and the orientation of the pointer and the phase of the pulse are controlled by the user to specify a 3D point in 3D space. A wireless receiver provides six degree-of-freedom (DOF) position of the spatial location of the pointer, as well as the phase signal.
