摘要： An apparatus, system and method for telepresence communications in an environment of a virtual location between two or more participants at multiple locations. 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 and/or otherwise captured from a second participant at a second location are processed to generate a first virtual representation of the second participant in the virtual environment from the perspective of the first participant. Likewise, second perspective data descriptive of the perspective of the virtual location environment experienced by the second participant and feature data extracted and/or otherwise captured from features of the first participant are processed to generate a second virtual representation of the first participant in the virtual environment from the perspective of the second participant. The first and second virtual representations are rendered and then displayed to the first and second participants, respectively. The first and second virtual representations are updated and redisplayed to the participants upon a change in one or more of the perspective data and feature data from which they are generated. The apparatus, system and method are scalable to two or more participants.

摘要： An electro-optic display device (10) includes an electro-optic cell (14), such as a liquid crystal cell, a reflector (16), and a transmission holographic optical element (12). The electro-optic cell (14) includes a cell front (56), a cell back (58) opposite the cell front (56), and at least one cell region having a transparent mode. The reflector (16, 46) receives light that traverses the cell region and reflects the light toward the cell front (56). The transmission holographic optical element (12) is optically coupled to the cell front (56) and includes a front face (24). The holographic optical element (12) receives a light ray (26) at a first angle (31) and a second reflected light ray and diffracts the reflected light ray, such that the reflected light ray is emitted from the front face (24) at a third angle (34) that is distinct from the first angle (31), thereby increasing the contrast and apparent brightness of the display device (10).

摘要： A liquid crystal display device (10) for forming a display includes a liquid crystal panel (12), a switchable holographic optical element (14), and a reflective holographic optical element (16). Ambient light illuminates a front polarizer (18), which polarizes the ambient light and transmits the polarized light to the liquid crystal cell (20). The liquid crystal cell (20) receives the polarized light and transmits polarized light derived from the incident 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). While in a first mode, the switchable holographic optical element (14) redirects the light back toward the liquid crystal panel (12) within a first viewing cone (34) to form the display. 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 back toward the liquid crystal panel (12) in a second viewing cone (36) to form the display. The second viewing cone (36) is preferably narrower than the first viewing cone (34), which increases the intensity of the light within the second viewing cone (36).

摘要： A liquid crystal display device (30) that is illuminatable by diffuse ambient light comprises a liquid crystal panel (32) and a reflective holographic optical element (34). Diffuse ambient light illuminating the front side (36) of the liquid crystal panel and traversing the liquid crystal panel is received at a reflection site (66) and is redirected with a reflection pattern (68) to retraverse the liquid crystal panel to form a bright pixel for a display. By concentrating diffuse light within a preferential reflection pattern, the reflective holographic optical element provides enhanced brightness for viewing the display under ambient light conditions. In one aspect, the reflective holographic optical element is a transflector (158, 208) and is combined with an internal light source (170, 220) for illuminating the display using either reflected ambient light or backlighting.
