Abstract:
1. A device comprising: a tilt sensor configured to automatically determine a neutral position of a device in relation to at least a first axis, and further configured to measure an angular displacement of the device about at least the first axis; at least a first control associated with a first plurality of output signals; and a processor configured to receive a selection of the first control and further configured to output one of the first plurality of output signals based at least upon the selection and the angular displacement, wherein the neutral position of the device is determined in relation to at least a second axis, orthogonal to the first axis, wherein the angular displacement includes a first-axis component and a second-axis component, wherein the neutral position of the device is automatically determined in relation to at least a third axis orthogonal to the first axis and the second axis, and wherein the angular displacement includes a third-axis component.
