摘要

The present invention provides an apparatus for entering data into a computing device. The apparatus comprises at least two haptic keys having more than one state of activation, a graphical user interface for presenting hierarchically organised information to a user of the computing device, and a control means for controlling the generation of input data with respect to a haptic key selected, the current state of activation of the selected haptic key, and the information presented by the graphical user interface.
