ADAPTABLE ACTUATED INPUT DEVICE WITH INTEGRATED PROXIMITY DETECTION

A hardware input device is disclosed in which at least two modes of manual user input can be provided within the same surface area of the device, including actuating or pressing multiple keys or buttons etc. as well as touch and/or gesturing by the user. A disclosed embodiment has actuated keys/buttons with associated sensors for detecting actuation; a second set of sensors for detecting proximity e.g. of a user's extremities is co-located on the input device. In one embodiment, infrared sensors for proximity detection are integrated with the traditional plastic keys/buttons of a computer keyboard or other personal electronics device. In some embodiments, the elevation of actuated input elements can be controlled by a processor, so that the physical configuration of keys/buttons available to the user can be dynamically reconfigured under program control. Methods are disclosed for using the input device to facilitate a heads-up style of interaction.
