A custom frequency keyboard for somebody using a joystick. Up and Down movement is easier than side to side movement for this user. The most frequent letters are in the centre column where possible. I have also tried to locate the most frequent digraphs close together so the joystick user has the shortest movement to transverse.
Space is put out of the way as the user prefers to use the prediction cells rather than the space.
The links are to link into the computer control user. However if you find this keyboard useful and want help to build these pages please do get in touch. firstname.lastname@example.org
