Abstract
A touch-type keyboard with multiple functions associated with each key which functions are uniquely selected based on finger position. Each of a plurality of mechanical keys are associated with at least three functions. Each key has a surface area for actuation by a user's finger. The surface area is mapped to zones associated with each function. Function actuation is determined by detection of the finger position when the key is actuated. In the event of a finger overlapping multiple zones during actuation, unique function selection is determined at least in part from the pattern of finger overlap with the plural zones.
