Mobile device with user interaction capability and method of operating same
In one embodiment a method of operating a mobile device includes sensing either an orientation or a movement of the mobile device, determining a command based on the sensed orientation or sensed movement, sensing a proximity of an object in relation to at least a portion of the mobile device, and executing the command upon the proximity of the object being sensed. In another embodiment, a method of operating a mobile device governs a manner of interaction of the mobile device relative to one or more other mobile devices. In at least some embodiments, at least one of the mobile devices includes an accelerometer and an infrared proximity sensor, and operation of the mobile device is determined based upon signals from those components.
1. A mobile device comprising:
a processor;
a wireless transceiver coupled to the processor;
an accelerometer coupled to the processor to provide an accelerometer signal to the processor indicative of a first orientation, first movement, or first acceleration of the mobile device; and
an infrared proximity sensor, coupled to the processor, for providing an infrared proximity sensor signal indicative of a presence of an object in proximity to the infrared proximity sensor,
wherein the processor determines based at least in part upon the accelerometer signal whether a first criterion has been met and, upon determining that the first criterion has been met, enters a first state in which the processor is prepared to execute a command upon receiving the infrared proximity sensor signal, and
wherein the processor, upon receiving the infrared proximity sensor signal while in the first state, executes the command.
2. The mobile device of claim 1 , wherein the command relates to either (a) changing a display characteristic of a display on the mobile device, or (b) causing transmission of data from the mobile device to a remote location.
3. A system comprising the mobile device of claim 1 and further comprising an additional mobile device, wherein the processing determines whether the first criterion has been met based upon both the accelerometer signal and an additional signal received from the additional mobile device that is indicative of a second orientation of the additional mobile device, and wherein whether the first criterion is met depends upon a degree to which the first orientation is similar angularly to the second orientation.
4. The mobile device of claim 1 , wherein the processor causes repeated execution of the command upon receiving the infrared proximity sensor signal repeatedly.
5. The mobile device of claim 1 , further comprising an electronic compass coupled to the processor to provide a third signal to the processor.
6. The mobile device of claim 5 , wherein the third signal is further indicative of the first orientation of the mobile device; and wherein the processor determines based at least in part upon the accelerometer signal and the third signal whether the first criterion has been met.
7. A first mobile device comprising:
a processor;
a wireless transceiver coupled to the processor;
an accelerometer that is a component of the first mobile device and that is coupled to the processor to provide an accelerometer signal to the processor indicative of a first angular orientation of the first mobile device; and
an infrared proximity sensor, coupled to the processor, for providing an infrared proximity sensor signal indicative of a presence of an object in proximity to the infrared proximity sensor,
wherein the processor determines, based at least in part upon the accelerometer signal and an additional signal received from an additional mobile device that is indicative of an additional angular orientation of the additional mobile device, whether a first criterion has been met depending upon a degree to which the first angular orientation is similar to the additional angular orientation,
wherein the first mobile device and additional mobile device are paired with one another,
wherein, upon determining that the first criterion has been met, the processor enters a first state in which the processor is prepared to execute a command causing transmission of data from the first mobile device to the additional mobile device upon receiving the infrared proximity sensor signal, and
wherein the processor, upon receiving the infrared proximity sensor signal, executes the command.
8. The mobile device of claim 7 , wherein the transmission of data is to the additional mobile device because the additional mobile device has been identified as being substantially similarly orientated relative to the first mobile device, but not to a further mobile device that is substantially dissimilarly orientated relative to the first mobile device.
9. The mobile device of claim 8 , wherein the processor causes repeated execution of the command upon receiving the infrared proximity sensor signal repeatedly.
10. The mobile device of claim 9 , further comprising an electronic compass coupled to the processor to provide a third signal to the processor, wherein the third signal is further indicative of the orientation of the mobile device; and wherein the processor determines based at least in part upon the accelerometer signal and the third signal whether the first criterion has been met.
