Abstract:
A method and apparatus is provided in which a digital image is transmitted to a presentation projector resource over a wireless transmission medium using a reduced amount of transmission bandwidth by transmitting a subset of the digital image data. The subset image data may be a delta subset that represents those areas of the image that have changed since the previous transmission. The subset image data may also be a scalable vector graphics representation of the subset of the digital image. Header data is provided to further describe the subset image data. A projector discovery logic selects a suitable projector resource based on the order or signal strength of the discovery replies. A wireless image transmission session is established with the selected projector resource during which the projector is unavailable to other devices. The subset image data may be compressed and transmission coordinated with the projector resource so that the data is sent only when it is ready to be received. A wireless to digital visual interface (DVI) graphics engine decompresses and renders the image for output to a DVI connector receptacle. The rendered image is projected by the projector resource in accordance with the associated header data so that the exact image that appears on the image generation device also appears on the projected display.

Abstract:
Optical filtered sensor-in-pixel technology for touch sensing, in which a waveguide receives infrared light emitted by a light source and causes at least some of the received infrared light to undergo total internal reflection within the waveguide. A frustrating layer is disposed relative to the waveguide so as to contact the waveguide when a touch input is provided. The frustrating layer causes frustration of the total internal reflection of the received infrared light within the waveguide at a contact point between the frustrating layer and the waveguide. A sensor-in-pixel display displays an image that is perceivable through the waveguide and the frustrating layer and includes photosensors. The photosensors have a photosensor corresponding to each pixel of the image and sense at least some of the infrared light that escapes from the waveguide at the contact point.

A touch-screen device includes a radiation source, a pliable waveguide configured to receive radiation emitted by the radiation source and to cause some of the received radiation to undergo total internal reflection within the pliable waveguide, a frustrating layer disposed relative to the pliable waveguide so as to enable the frustrating layer to contact the pliable waveguide when the pliable waveguide is physically deformed, the frustrating layer being configured to cause frustration of the total internal reflection of the received radiation within the pliable waveguide at a contact point between the frustrating layer and the pliable waveguide when the pliable waveguide is physically deformed to contact the frustrating layer such that some of the received radiation undergoing total internal reflection within the pliable waveguide escapes from the pliable waveguide at the contact point, and an imaging sensor configured to detect some of the radiation that escapes from the optical waveguide.

The interactive display system further including a display assembly and an optical layer interposed the touch sensor overlay and the display assembly.
Abstract:
A display and image-capture device comprises a plurality of image sensors and a plurality of light-emitting elements disposed on a substrate. A plurality of lenses is disposed on a light-incident side of the image sensors, and the lenses are configured to direct light toward the image sensors. The image sensors may be configured to detect directional information of incident light, enabling the device to function as a plenoptic camera. In some examples, the image sensors and lenses are integrated into a plurality of microcameras.
