A two-way communication apparatus has a user interface comprising a touchpad 10 and a controller 16 responsive to the touchpad 10. The touchpad 10 has a plurality of permanent images 26, 30 associated therewith. Selected ones of the permanent images 26, 30 are made visible and others are concealed based upon the operating mode of the two-way communication apparatus. Also mentioned is a method of inputting commands wherein the controller 16 recognizes a plurality of bi-directional strokes (gestures), including a first bi-directional stroke indicative of a first telephone command and a second bi-directional stroke indicative of a second telephone command, from the touchpad 10. Dialled digits may be input, using largely uni-directional strokes (fig7), whilst # and *keys are input using tri-directional strokes. |
