摘要： Display components (e.g., liquid crystal displays (LCDs)) are viewable at different viewing angles, for example, by a first user positioned directly in front of the display and by a second user positioned to one side of the display. Many displays present a consistent display across a wide range of viewing angles, but these displays may consume energy and/or compromise user privacy. Presented herein are configurations of backlights for display devices featuring an adjustable viewing angle, such that a user may select a narrower viewing angle in usage scenarios involving power consumption or privacy, and may select a wider viewing angle in usage scenarios involving plentiful power and fewer privacy concerns. Such configurations may include multiple banks of backlight lamps generating backlight at different viewing angles; an electrowetting electrode as an adjustable collimator; adjustable diffusers that may adjustably scatter light passing therethrough; and/or a combination of such adjustable elements.

摘要： A user may issue commands to a computing device by moving a pointer within a light field. Sensors may capture light reflected from the moving pointer. A virtual touch engine may analyze the reflected light captured as light portions in a sequence of images by the sensors to issue a command to a computing device in response to the movements. Analyzing the sequence of images may include finding the light portions in the sequence of images, determining a size of the light portions, and determining a location of the light portions.

摘要： Methods, computer systems, and computer-readable media for accelerating a learning-to-rank algorithm using a central processing unit (CPU) and a graphics processing unit (GPU) are provided. The GPU processes document pairs created by the CPU in parallel to generate a lambda-gradient value and a weight for each document. The CPU builds a regression tree for the documents. The GPU is utilized to accelerate this process by constructing histograms of feature values, wherein the address of bins collecting the same feature value are shifted during the construction of the histogram. The output of the regression tree is a score for each document which is used to rank or order the document on a search engine results page.

摘要： In an exemplary embodiment, an on-board camera is used as a controller for a hand-held game device. Control information is provided to a game application via video captured by the camera. As the hand-held device is moved, features of the captured video are tracked. The relative motion between the tracked features and the hand-held device is translated into control information for the game application. Aspects of the game application are rendered on a display of the hand-held game device in accordance with the control information. For example, from a third person perspective, viewing a game character from overhead, rotation of the hand-held game device can be translated into rotation of the character. From a first person perspective, seeing the game through the eyes of the game character, rotation of the hand-held game device can be translated into observing various challenges coming from different directions.
