Abstract:
1. A touch sensitive key based input device comprising: a plurality of keys, each key configured to generate a character output when depressed and released within a time threshold; a spacebar key with a touch sensitive surface area, wherein said touch sensitive surface area is enlarged relative to a surface area of each key of the plurality of keys to provide an emulated trackpad directly on said spacebar key; and a controller (i) generating a first output for entry of a space when said spacebar key is physically depressed and then released within a specified time duration, (ii) generating a second output directed to a first set of trackpad emulated functionality in response to a non-stationary touch over the touch sensitive surface area of the spacebar key when the spacebar key is not depressed, and (iii) generating, without output for continuous entry of a space, a third output directed to a second set of trackpad emulated functionality in response to a non-stationary touch over the touch sensitive surface area of the spacebar key while the spacebar key is depressed beyond the specified time duration.
