摘要： The present disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for providing virtual keyboards. In one aspect, a system includes a camera, a display, a video feature extraction module and a gesture pattern matching module. The camera captures a sequence of images containing a finger of a user, and the display displays each image combined with a virtual keyboard having a plurality of virtual keys. The video feature extraction module detects motion of the finger in the sequence of images relative to virtual sensors of the virtual keys, and determines sensor actuation data based on the detected motion relative to the virtual sensors. The gesture pattern matching module uses the sensor actuation data to recognize a gesture.

摘要： This disclosure describes techniques for modifying application program interface (API) calls in a manner that can cause a device to render native three dimensional (3D) graphics content in stereoscopic 3D. The techniques of this disclosure can be implemented in a manner where API calls themselves are modified, but the API itself and the GPU hardware are not modified. The techniques of the present disclosure include using the same viewing frustum defined by the original content to generate a left-eye image and a right-eye image and shifting the viewport offset of the left-eye image and the right-eye image.

摘要： An apparatus and method for displaying content is disclosed. A particular method includes determining a viewing orientation of a user relative to a display and providing a portion of content to the display based on the viewing orientation. The portion includes at least a first viewable element of the content and does not include at least one second viewable element of the content. The method also includes determining an updated viewing orientation of the user and updating the portion of the content based on the updated viewing orientation. The updated portion includes at least the second viewable element. A display difference between the portion and the updated portion is non-linearly related to an orientation difference between the viewing orientation and the updated viewing orientation.

摘要： A method and device for performing and processing user-defined clipping in object space to reduce the number of computations needed for the clipping operation. The method and device also combine the modelview transformation of the vertex coordinates with projection transform. The user-defined clipping in object space provides a higher performance and less power consumption by avoiding generation of eye coordinates if there is no lighting. The device includes a driver for the user-defined clipping in the object space to perform dual mode user-defined clipping in object space when a lighting function is disabled and in eye space when the lighting function is enabled.

摘要： This disclosure describes an apparatus, such as a wireless communication device, that applies a direct evaluation technique to render triangles for the 3D graphical environment. The apparatus includes a rendering engine that defines a rectangular area of pixels, referred to as a bounding box, that bounds the area to be rendered. The rendering engine evaluates coordinates associated with the pixels of the rectangular area to selectively render those pixels that fall within the triangular area. The direct evaluation triangle rendering algorithm may require fewer complex operations than the more computationally intensive interpolation process employed by other systems. As a result, the apparatus may present a 3D graphical environment while preserving as much as possible the available power.

摘要： An apparatus for accurate endpointing of speech in the presence of noise includes a processor and a software module. The processor executes the instructions of the software module to compare an utterance with a first signal-to-noise-ratio (SNR) threshold value to determine a first starting point and a first ending point of the utterance. The processor then compares with a second SNR threshold value a part of the utterance that predates the first starting point to determine a second starting point of the utterance. The processor also then compares with the second SNR threshold value a part of the utterance that postdates the first ending point to determine a second ending point of the utterance. The first and second SNR threshold values are recalculated periodically to reflect changing SNR conditions. The first SNR threshold value advantageously exceeds the second SNR threshold value.
