    摘要： Disclosed is a method and apparatus for implementing a virtual mouse. In one embodiment, the functions implemented include activating the virtual mouse, determining a location of a cursor icon associated with the virtual mouse, and deactivating the virtual mouse. In various embodiments, the position of virtual mouse is determined by a processor based upon an orientation or position of a finger touching a touchscreen and a measured or calculated pressure applied by the finger to the touchscreen.

    摘要： Systems and methods are disclosed for determining a touch position from data received from a touch panel. In one implementation, an apparatus for processing a touch input signal includes a processor that may be configured for parallel processing, a touch device, a memory, operably connected to the processor, and configured to store processor instructions. The processor instructions can configure the processor to receive a plurality of data points corresponding to a plurality of touch events on the touch device, determine a center of mass estimate from the plurality of data points, determine a search radius of center of mass estimate, and determine an optimal touch point position based on the center of mass estimate and the search radius using the processor.

    摘要： A set of even interpolated sub-pixels is formed based on a pixel window and a tap coefficient register having a tap coefficient set, the pixel window is shifted and, applying the tap coefficient register a set of odd interpolated pixels is formed. The set of even interpolated sub-pixels and the set of odd interpolated sub-pixels are accumulated, repeatedly, until a termination condition is let. In the accumulating, the tap coefficient register is updated with another tap coefficient set, the pixel window is shifted, and the even interpolated pixels are incremented, the pixel window is then shifted again and the odd interpolated pixels are incremented.

    摘要： A method for performing texture decoding in a multi-threaded processor includes substantially simultaneously decoding, in multiple hardware threads, at least two macro-blocks of a VP8 frame. Each hardware thread decodes one macro-block at a time. The method may also include assigning a macro-block from the at least two macro-blocks of the VP8 frame to a hardware thread of the multi-threaded processor.

    摘要： Video encoding techniques are described. In one example, a video encoding technique includesidentifying a pixel location associated with a video block in a search space based on motion vectors associated with a set of video blocks within a video frame to be encoded, wherein the video blocks in the set are spatially located at defined locations relative to a current video block of the video frame to be encoded. A motion estimation routine can then be initialized for the current video block at the identified pixel location. By identifying a pixel location associated with a video block in a search space based on motion vectors associated with a set of video blocks within a video frame, the phenomenon of spatial redundancy can be more readily exploited to accelerate and improve the encoding process.

    摘要： Methods, devices, and computer program products for using touch orientation to distinguish between users are disclosed herein. In one aspect, a method of identifying a user of a touch device from a plurality of users of the touch device is described. The method includes receiving touch data from a touch panel of the touch device, the touch data indicating a user's touch on the touch screen. The method further includes determining an orientation of the user's touch based on the received touch data. Finally, the method includes identifying the user of the plurality of users which touched the device, based at least in part on the orientation of the touch.
