1. A system comprising: a tilt sensor configured to automatically determine a neutral position of a device in relation to at least a first axis, to measure an angular displacement of the device about at least the first axis, and to detect shaking of the device; at least a first control located on the device; and a processor configured to receive a selection of the first control and further configured to output an output signal based at least upon the selection and the angular displacement or based upon detecting the shaking of the device, wherein the tilt sensor is configured to measure the angular displacement of the device with respect to at least one tilt region defined around the first axis and the processor is configured to, when the processor receives the selection of the first control at a time when the angular displacement of the device is outside of any defined tilt region, provide no output, provide output corresponding to a closest defined tilt region, or provide output corresponding to a most recent output.
