Electronic device with sensing assembly and method for interpreting offset gestures
First Claim
1. A method for controlling an electronic device, the method comprising:
- providing as part of the electronic device a display screen for displaying content and 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 as an external object moves in a first specified pattern of movement which is offset from a generally centered position with respect to the sensing assembly;
for each of the 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 the first specified pattern of movement of the object, and to detect a reference offset location corresponding to an end of the first specified pattern of movement of the object;
performing a centering operation in response to the identification of the first specified pattern of movement, wherein the centering operation moves an indicator to a predetermined reference location on the display screen, wherein the predetermined reference location is then associated with the reference offset location; and
subsequently controlling sequential locations of the indicator on the display screen in accordance with further determined locations of the object relative to the reference offset location.

Abstract
A method for controlling an electronic device includes providing a display screen and a sensing assembly including at least one photoreceiver and phototransmitters. Emission of infrared light by the phototransmitters is controlled as an object moves in a first specified pattern of movement and then moves in a second specified pattern of movement, and measured signals are generated. The measured signals are evaluated to identify the first specified pattern, to detect a reference offset location, and to determine, for each of a group of time periods when the object is moving in the second specified pattern, a corresponding location of the object during that period. A centering operation is performed in response to the identification, wherein the centering operation moves an indicator to an initial predetermined reference location on the display screen; and sequential locations of the indicator are controlled in accordance with the corresponding determined locations.
