Abstract
Systems and methods are described for performing contactless gesture recognition for a computing device, such as a mobile computing device. An example technique for managing a gesture-based input mechanism for a computing device described herein includes identifying parameters of the computing device relating to accuracy of gesture classification performed by the gesture-based input mechanism and managing a power consumption level of at least an infrared (IR) light emitting diode (LED) or an IR proximity sensor of the gesture-based input mechanism based on the parameters of the computing device.
