Abstract: Touch sensitive displays are disclosed that can include circuitry that is segmented into multiple portions that can be independently operated. Touch sensitive display circuitry can be split in half with an upper portion and a lower portion that can each be independently operated. The separate circuitry portions can be used for performing display operations and for performing touch sensing operations. Display operations can be performed in one portion of the display while touch sensing operations are simultaneously performed in another portion of the display. Periodically, the operation being performed in a given portion of the display can be switched so as to alternatingly update that portion of the display and sense touch events in that region.

Abstract: Object tracking for device input can be improved by utilizing various tracking parameters to correlate objects between analyzed image frames. In some embodiments, relatively low resolution infrared cameras can be used for object tracking, in order to conserve resources on the device. Intensity segmentation can be used to identify potential objects of interest to be analyzed in captured image data. One or more tracking parameters, such as size, shape, and/or distance, can be specified for each of the objects in order to correlate objects between images. The correlations can be ranked by confidence or other such metrics in order to improve overall accuracy. Tracking data can also be stored for a period of time such that objects that are not clearly distinguishable for a while but then reappear can again be correlated with objects from earlier images.
