Electronic Device with Sensing Assembly and Method for Interpreting Consecutive Gestures
First Claim
1. A method for interpreting at least two consecutive gestures, wherein each gesture is a specified pattern of movement of an external object relative to an electronic device, the method comprising:
- providing as part of the electronic device a sensing assembly including at least one photoreceiver and a plurality of phototransmitters, wherein each phototransmitter is positioned to emit infrared light away from the electronic device about a corresponding central transmission axis, wherein each central transmission axis is oriented in a different direction with respect to the others;
controlling emission of infrared light by each of the phototransmitters during each of a plurality of time periods;
for each of the plurality of phototransmitters and for each of the plurality of time periods, generating a corresponding measured signal indicative of a respective amount of infrared light which originated from that phototransmitter during that time period and was reflected by the external object prior to being received by a photoreceiver;
evaluating the measured signals to identify a first gesture;
controlling the electronic device in response to the identification of the first gesture according to a first mode of operation of the electronic device;
determining a parameter of a second gesture; and
controlling the electronic device in response to the determined parameter of the second gesture according to a second mode of operation.

Abstract
A method for interpreting at least two consecutive gestures includes providing a sensing assembly having at least one photoreceiver and a plurality of phototransmitters, wherein each phototransmitter is positioned to emit infrared light away from the electronic device about a corresponding central transmission axis, wherein each central transmission axis is oriented in a different direction with respect to the others, and controlling emission of infrared light by each of the phototransmitters during each of a plurality of time periods. During each of the plurality of phototransmitters and for each of the plurality of time periods, a corresponding measured signal is generated which is indicative of a respective amount of infrared light which originated from that phototransmitter during that time period and was reflected by the external object prior to being received by a photoreceiver. The measured signals are evaluated to identity a first gesture, and the electronic device is controlled in response to identification of the first gesture according to a first mode of operation. A parameter of a second gesture is also determined, and the electronic device is controlled in response to the determined parameter of the second gesture according to a second mode of operation.
