    摘要： An interactive input system, a tool and a method for detecting the tool's identity in the interactive input system are provided, in which a touch location of the tool is detected. The system comprises a plurality of antennas. A set of selected antennas associated with the touch location are activated to generate electromagnetic field, thereby activating the tool to send out a unique identifier associated with an attribute of the pen tool. The unique identifier is received and detected by the interactive input system to determine the attribute of the pen tool. The pen tool comprise at least one coil, and at least one NFC transponder, wherein the at least one coil is activated by electromagnetic field to power the NFC transponder for transmitting the unique identifier.

    摘要： An interactive input system comprises an optical waveguide, a radiation source directing radiation into the optical waveguide, the radiation undergoing total internal reflection within the optical waveguide in response to at least one touch input on a surface of the optical waveguide. At least one imaging device is positioned adjacent to the waveguide, the at least one imaging device having a field of view looking inside the optical waveguide and capturing image frames thereof. Processing structure processes the image frames captured by the at least one imaging device to determine a location of the at least one touch input based on a frequency of reflections of the radiation appearing in the image frame.

    摘要： A three-dimensional (3D) interactive input system comprises a holographic image generator defining an enclosed space to accommodate a 3D object and configured to generate a holographic image of the 3D object that appears adjacent an input region of the holographic image generator. A projection unit is configured to project image data onto the 3D object, the image data projected onto the 3D object appearing on the holographic image. A sensing unit is configured to detect user proximity to the input region. Processing structure is configured to process sensing unit output and in response, update image data projected by the projection unit.

    摘要： A video conferencing display device a display panel, at least one imaging device and processing structure. The at least one imaging device has a field of view aimed at an inner surface of the display panel and captures images through the display panel such that when a user is positioned adjacent an outer surface of the display panel, the user appears in the captured images. The processing structure communicates with the at least one imaging device and processes the captured images to create a direct eye image for transmission to a remote device over a network.
