Abstract: An input device and methods for detecting user input using an input device. An example input device includes a multi-touch sensing display configured to detect multiple simultaneous triggers on a surface of the multi-touch sensing display as distinct input events. The input device also includes at least one mechanical control element arranged on the surface of the multi-touch sensing display. The at least one mechanical control element is configured to generate an input event. The input event is detected by the multi-touch sensing display in response to actuation of the at least one mechanical control element.

Abstract: A controller or adjustment device may adjust a value of a parameter for different functions. The adjustment device may include actuators, which may be associated with one or more functions. A light source in proximity to the adjustment device may identify the function of the device. Mixers and filters may automatically modify the hue and/or value of the color based on the selected function. A different color light may be used to identify different functions of the adjustment device.
