GESTURE RESPONSIVE USER INTERFACE FOR AN ELECTRONIC DEVICE

摘要

This disclosure provides systems methods and apparatus including computer programs encoded on computer storage media for providing a gesture responsive user interface for an electronic device. In one aspect an apparatus or electronic device has an interactive display that provides an input/output (I/O) interface to a user of the apparatus. The apparatus includes a processor a light emitting source and at least two light sensors. A secondary optical lens structures emitted light from the light emitting source into at least one lobe. Each light sensor outputs to the processor a signal representative of a characteristic of received light where the received light results from scattering of the structured emitted light by an object. The processor effectuates the I/O interface by recognizing from the output of the light sensors an instance of a user gesture and to control the interactive display and/or the apparatus in response to the user gesture.
