Joystick Text Entry with Date Stamp, Selection Keyboard, and EdgeWrite

are hit, not on the stroke path, so wiggle and jitter do not deter high recognition rates. Segmentation between letters is accomplished when the joystick snaps-to-center. EXPERIMENT We implemented joystick versions of date stamp, selection keyboard, and EdgeWrite for the Saitek P2500 game controller, which without modification has a square area bounding the stick. Date stamp is the roll-over method used on high-score screens in arcade games.

We compared these 3 methods in a single-factor withinsubjects study of 18 subjects who had never before used EdgeWrite. Entry method was fully counterbalanced across subjects. Subjects practiced for 5 minutes with the selectionbased methods and for 15 minutes with EdgeWrite, since they had to learn the gesture alphabet. We acknowledge that EdgeWrite takes long
