Inspired by Shack Hartmann Wavefront Patterns, a device may obtain three dimensional images for use in authentication. Since such images can have high resolution, damage in, for instance, skin on a finger may be recorded and used as part of a temporary template image. In future authentication attempts, an aged version of the temporary template image may be used. Additionally, reference points on the damage may be employed when authenticating.

Obtaining a biometric image and handling damaged biometrics

A device and method to detect a gesture made by an object in touch-less communication with the device are described. The device includes two or more ambient light sensors arranged at respective surface locations of the device, each of the two or more ambient light sensors configured to measure light intensity at the respective surface location. The device also includes a processor configured to detect the gesture based on a comparison of the light intensity measured at each of the respective surface locations at two or more time instants or measurement cycles.

Gesture detection using ambient light sensors

A device and method to detect a gesture made by an object in touch-less communication with the device are described. The device includes a collection engine to collect light intensity measurements of light intensity at two or more measurement cycles from two or more ambient light sensors arranged at respective surface locations of the device. The device also includes a processor to identify the gesture based on the light intensity measurements at each of the two or more ambient light sensors at two or more of the two or more measurement cycles, and a memory device to store a gesture library that associates the gesture with an output signal.

A device for detecting a carrying case using orientation signatures, and method therefor, is provided. The device includes: at least one orientation sensor; a memory storing one or more carrying-case insertion signatures; and, a processor configured to: receive output from the at least one orientation sensor as a function of time; and place the device in a carrying case mode when a time-dependent pattern in the output matches the one or more carrying-case insertion signatures.

A stylus is used to modify the appearance of objects rendered on a touch-sensitive display. One of a plurality of objects on the display is selected by making contacting the object with the stylus. The stylus tilt and stylus contact pressure are determined. The appearance of the selected object is modified in response to the stylus tilt of the stylus and the stylus contact pressure.
