Abstract:
Various embodiments provide a user device comprising a touch screen display having a touch screen input; a proximity detector arrangement comprising a plurality of sensors for detecting a location of an input device; and a control unit comprising a processor. The control unit is configured to receive data from the proximity detector to determine the location of the input device, including a value related to the distance of the input device to the display; and control the display to perform a zoom function to enlarge or reduce the size of content on a portion of the display based on the value related to the distance of the input device to the display. The proximity detector arrangement and control unit are configured to detect the location of the input device within a detection volume and to provide a gradual variation in enlargement or reduction of the size of content as the distance of the input device to the display varies. Providing a gradual variation in zoom allows for a more precise and enjoyable user experience.
Abstract:
Systems and methods are provided for presenting three-dimensional content on a display. An exemplary system for presenting a plurality of frames on a display comprises a first lens, a second lens, and an activation system. The activation system utilizes electromagnetic radiation to activate the first lens when a respective frame being presented on the display corresponds to the first lens, resulting in the first lens being substantially transparent and the second lens being substantially opaque, and to activate the second lens when a respective frame being presented on the display corresponds to the second lens, resulting in the second lens being substantially transparent and the first lens being substantially opaque.
Abstract:
Systems, devices and processes are described to transfer a media program from a media server to a playback device over a network. The media program is encoded in a multi-layer format having a plurality of layers comprising a base layer and at least one additional layer. The base layer supports playback of the entire media program at a lower resolution and each of the additional layers provides additional data that, when combined with the base layer, supports playback of the media program at a higher resolution. The base layer is initially transferred to allow playback of the media program at the lower resolution on the playback device. If sufficient resources remain after transfer of the base layer, then at least one of the additional layers may be subsequently transferred to allow playback of the media program at the higher resolution.
Abstract:
An active shutter device for use in securely displaying content from a display to a user. The secure content is encoded as a sequence of video frames interspersed within a set of video frames, at least some of the other frames within the set including obfuscating data. The device comprises a receiver for receiving a synchronisation signal, at least one shutter mechanism, and a processor. The processor, in response to the synchronisation signal, controls the shutter mechanism so as to synchronise the shutter mechanism with, for example, the refresh rate or the video frame display rate of the display. The processor is configured to receive a frame sequence corresponding to the sequence of video frames used of the secure content, and control the shutter mechanism, in response to the received frame sequence, to allow only the video frames in the secure sequence to pass through the shutter.
