    摘要: A system for controlling infrared (IR) enabled devices by projecting coded IR pulses from an active illumination depth camera is described. In some embodiments, a gesture recognition system includes an active illumination depth camera such as a depth camera that utilizes time-of-flight (TOF) or structured light techniques for obtaining depth information. The gesture recognition system may detect the performance of a particular gesture associated with a particular electronic device, determine a set of device instructions in response to detecting the particular gesture, and transmit the set of device instructions to the particular electronic device utilizing coded IR pulses. The coded IR pulses may imitate the IR pulses associated with a remote control protocol. In some cases, the coded IR pulses transmitted may also be used by the active illumination depth camera for determining depth information.

    摘要: A video projector device includes a visible light projector to project an image on a surface or object, and a visible light sensor, which can be used to obtain depth data regarding the object using a time-of-flight principle. The sensor can be a charge-coupled device which obtains color images as well as obtaining depth data. The projected light can be provided in successive frames. A frame can include a gated sub-frame of pulsed light followed by continuous light, while the sensor is gated, to obtain time of flight data, an ungated sub-frame of pulsed light followed by continuous light, while the sensor is ungated, to obtain reflectivity data and a background sub-frame of no light followed by continuous light, while the sensor is gated, to determine a level of background light. A color sub-frame projects continuous light, while the sensor is active.

    摘要: A method for encoding information that is encoded in spatial variations of the intensity of light characterized by a first wavelength in light characterized by a second wavelength, the method comprising: transmitting the first wavelength light through a photo-conducting material in which electron-hole pairs are generated by absorbing photons from the first wavelength light to generate a first density distribution of electrons homologous with the spatial variations in intensity of the first wavelength light; trapping electrons from the first electron density distributions in a trapping region to generate an electric field homologous with the density distribution in a material that modulates a characteristic of light that passes therethrough responsive to an electric field therein; transmitting a pulse of light having sufficient energy to generate electron-hole pairs in the photo-conducting material through the modulating material and thereafter through the photo-conducting layer to generate a second additional electron density homologous with the first electron density distribution; trapping electrons from the second electron density distribution in the trapping region; and transmitting the second wavelength light through the modulating material thereby modulating the second wavelength light in response to the electric field and encoding it with the information.
