Abstract
Fingertip-sized discrete areas are provided on a slate computer and have different tactile characteristics than the remainder of the surface on which they are disposed. The discrete areas are arranged to mimic home keys of a keyboard and each discrete area corresponds to a respective home key. In this way, a user is given tactile feedback of when fingers are properly placed in the home position, with home key finger placement triggering the presentation of a full keyboard on screen. Other embodiments do not use tactilely distinct keys, with simultaneous placement of two or more fingers on the computer triggering display of the virtual keyboard.
