Abstract: A telepresence communications is provided at a virtual location between two or more participants at multiple locations (100, 200). First perspective data descriptive of the perspective of the virtual location environment experienced by a first participant at a first location and feature data extracted from features of a second participant at a second location (210, 220) are processed to generate a first virtual representation of the second participant in the virtual environment from the perspective of the first participant (250). Likewise, second perspective data descriptive of the perspective of the virtual location environment experienced by the second participant is processed to generate a second virtual representation of the first participant in the virtual environment from the perspective of the second participant (260). The first and second virtual representations are rendered and then displayed to the participants (260, 270).

Abstract: A dual mode display (100) includes a monochrome reflective direct view display (110) and a full color virtual display (150) located behind the monochrome reflective direct view display. The monochrome reflective direct view display includes a display panel (112) having a first pixel arrangement and a narrowband reflector (114) located behind the display panel. The virtual display has a second pixel arrangement, wherein each pixel emits light in one of three primary color bands through the monochrome reflective direct view display, and wherein the light emitted by each pixel, in combination with light emitted by other pixels of the virtual display, generates a full color virtual image from the dual mode display. In one embodiment the virtual display is a virtual high information content display and the three primary color bands (205, 210, 215) do not overlap a first color band of the narrowband reflector (220).

Abstract: A cell of a combination full color and monochromatic display comprises a first polarizer (102), a second polarizer (106) and an optical switching cell (104). The optical switching cell (104) is positioned between the first polarizer (102) and the second polarizer (106) and is operable to alter the polarization of transmitted light. A backlight (110) emits light that is incident upon the second polarizer (106). A hologram (108) positioned between the backlight elements (110) and the second polarizer (106) reflects a portion of an ambient light incident upon the hologram. The display may be operated in a first mode, for which the backlight elements emits light of a plurality of colors, and a second mode for which the backlight emits light of at most one color.

Abstract: A first language to second language translator (11) converts text comprising a message in a first language into text representing that message in a second language. A text to speech transducer (12) then synthesizes an audiblized version of the text in the second language. An animated display driver (14) creates a corresponding display (15) of an image (16) that includes a mouth (17) that moves appropriately and synchronously with respect to the audiblized second language. In other embodiments, other facial features can be animated as well. Such animation can be random and unrelated to the appearance of the original speaker. Or, such animation can accurately represent at least some alterations to facial features of the original speaker while speaking. In some embodiments, the facial features can be altered by correlating specific detected alterations with specific corresponding substantive content in the original message and the translated text.

Abstract: High quality epitaxial layers of monocrystalline materials (26) can be grown overlying monocrystalline substrates (22) such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer (24) comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer (28) of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline material layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. Electro-optic structures (232) may be integrally provided with such semiconductor structures, which semiconductor structures may also include light-emitting devices and control circuitry.

Abstract: A liquid crystal display device (10) includes a liquid crystal panel (12), a switchable holographic optical element (14), and a reflective holographic optical element (16). A front polarizer (18) polarizes ambient light and transmits the light to the liquid crystal cell (20), which receives the light and transmits polarized light to a back polarizer (22). The back polarizer (22) polarizes the light and transmits the light to the switchable holographic optical element (14), which, in a first mode, redirects the light within a first viewing cone (34). In a second mode, the switchable holographic optical element (14) is transparent and transmits the light to the reflective holographic optical element (16). The reflective holographic optical element (16) redirects the light in a second viewing cone (36). The second viewing cone (36) is preferably narrower than the first viewing cone (34), which increases the light intensity within the second viewing cone (36).

Abstract: The present invention provides a system for reducing the size of a projection display system. This is achieved by using an emissive imager that comprises a large number of emissive pixels. The emissive pixels provide both light output and light modulation functions. This eliminates the need for a separate illumination source. Each emissive pixel represents a pixel (or a sub- pixel for color projection) of an image to be projected. The light signals produced and modulated by the emissive imager are passed through a microlens array. The microlens array collects and reshapes the emitted light signals from the emissive pixels. Each microlens forms a light beam with a concentrated non-Lambertian radiation profile. The non-Lambertian radiation profile helps in effective collection of light at a projection lens. Finally, the projection lens collects this light and projects a magnified image on a projection screen.
