One embodiment includes an apparatus that receives gesture-based touch inputs from a user to provide keyboard functionality, via a limited number of input regions, to a separate digital device. The apparatus comprises: a touch-sensitive array; a processor; a communication module; and a casing. The touch-sensitive array defines a first zone with a plurality of radially-arranged touch regions, wherein the touch-sensitive array detects user touches at the regions of the first zone. The processor communicates with the touch-sensitive array, and distinguishes between various user input types for each region of the first zone. The processor generates an output that is a character associated with the input type. The communication module transmits the output to the separate digital device. The casing substantially houses the processor, the communication module and the touch-sensitive array.
