Abstract
Abstract A user interface device for inputting and outputting information. The user interface device includes a plurality of keys slidably retained within a housing, each key being associated with a plurality of alphanumeric characters or functions. The keys are joined together to slide substantially in unison. The user interface device also includes a pressure sensor configured to detect pressure applied to one or more of the plurality of keys, a direction sensor configured to detect direction of motion of the plurality of keys, a selection component for selecting at least one of an alphanumeric character or function based on the sensed pressure and sensed direction of motion, and an output device for presenting the selected at least one alphanumeric character or function based on the sensed pressure and sensed direction of motion. The selected alphanumeric character or function is associated with the key where the pressure was sensed and with an associated direction closest to the sensed direction of motion. Each alphanumeric character and function associated with each key is further associated with a direction of motion of the plurality of keys.
