Abstract: A controller bypasses processing raw image data captured by an image sensor at a wearable device and selects among modes of operation, to direct the raw image data to a light engine, to a transmitter, and/or to a computer vision engine. The light engine outputs display light based on the raw image data, the transmitter transmits the raw image data external to the wearable device, and the computer vision engine analyzes the raw image data to identify at least one feature represented in the raw image data and outputs computer vision data. The modes of operation selected by the controller reduce or eliminate intensive image signal processing operations performed by the wearable device on the raw image data.

Abstract: In order to manage power on a wearable computing device, a processor of the wearable computing device identifies one or more events. The processor determines a priority of each of the one or more events. Based on the priority of each of the one or more events, the processor determines whether to process the event. When the processor determines that the event is to be processed, the processor determines whether to defer processing of the event.

Abstract: A touch screen display of an electronic device is calibrated. The method includes receiving input comprising selections of features registered at the touch screen display, filtering the input based on characteristics determined during the receiving to determine if the input is to be used for calibrating, for each input used for calibrating, determining a difference between registered touch location and a respective target for the selection and subtracting an offset from the difference, thereby providing remainders of differences for the selections, and calibrating by adjusting a prior calibration based on the remainders if the input is determined to be used for calibrating.

Abstract: A system and a method for compositing graphics on a computing device are provided. The computing device includes one or more hardware layers. The method includes determining if the number of surfaces to be displayed by the computing device is more than the number of the hardware layers. If so, two or more of the surfaces are combined to form one or more pseudo surfaces. The combined number of the pseudo surfaces and the remaining ones of the surfaces is equal to or less than the number of the one or more hardware layers. This allows for each of the pseudo surfaces or the remaining ones of the surfaces to be assigned to separate hardware layers. The computational cost for combining the surfaces is also considered during the process.
