Abstract

A touch-based input device is disclosed providing a reconfigurable user interface. Said touch-based input device comprises an input receiving element having a touch sensitive contacting surface as part of a first configured user interface adapted to receive an applied force, a sensing element operable to detect and to determine at least a location of said applied force, and at least one static component removably disposed at a first location about said input receiving element, and adapted to at least partially define said first configured user interface. Said static component is movable to a second location about said input receiving element to reconfigure said user interface and to at least partially define a second configured user interface.
