Abstract: Techniques for determining whether touch-input gestures approximate straight lines and for animating a display with such gestures are described. The techniques determine a linear regression line for pixel locations comprising a gesture, determine distances of the pixel locations from the linear regression line, and render the set of pixel locations to the display based on the distances and a threshold.

Abstract: Motions or gestures can provide input to an electronic device by capturing images of a feature used to provide the motions or gestures, then analyzing the images. Conventional cameras have a limited field of view, creating a “dead zone” near the device that is outside the field of view. Various embodiments utilize an array of detectors positioned behind a display screen that are configured to operate as a large, low resolution camera. The array can resolve objects within a distance of the device sufficient to cover at least a portion of the dead zone. In some embodiments the device can include one or more infrared (IR) emitters to emit IR light that can be reflected by an object in the dead zone and detected by the detectors. The use of multiple emitters at different locations enables at least some depth information to be determined from the array images.
