摘要
Techniques are described for tracking and recognizing gestures performed within a field-of-view of a sensor. In one or more implementations, the techniques may be implemented within an electronic device that is configured to receive a signal from a sensor in response to the sensor detecting a gesture occurring within a field of view of the sensor. A lens is positioned over the sensor to collimate light incident on the lens and to pass the collimated light to the sensor. The electronic device is configured to generate one or more light intensity ratios based upon the signal. The electronic device is then configured to determine a type of gesture performed based upon the one or more light intensity ratios.
