Abstract: AN INTERFACE FOR ALLOWING A USER TO SELECT AN INPUT FOR A COMPUTING DEVICE FROM A SET OF AVAILABLE INPUTS A system 1 for allowing a user 2 to select a text character from a set 3 of available text characters. System 1 includes a plurality of actuators 6 in the form of three separate spaced apart AAC switches 7, 8, and 9 that are available to user 2 to select by manually physically depressing the respective switches. The characters in set 3 are allocated to three mutually exclusive subsets 11, 12 and 13 which are associated with respective switches 7, 8 and 9. A processor 15 within a laptop computer 16 generates a display signal. The processor is responsive to user 2 selecting one of switches 7 and 8 for determining if the respective associated subset 11 and 12 includes a single character. If the respective associated subset does include a single character, processor 15 selects the single character. Alternatively if the associated subset does not include a single character, processor 15 includes the characters in that selected subset in mutually exclusive sub-subsets which are allocated to respective switches 7 and 8. An output device, in the form of a display 17 for computer 16, is responsive to the display signal for displaying the selected character. -.., '7.1I ................................................................................................................................................................................................... . . . . .
