Evaluation of a Multi-Device Extension of Quikwriting
Poika Isokoski, Roope Raisamo · 2003
Several new text entry methods for mobile computers have been proposed recently. Many of these have not been tested to reveal whether they in fact perform as advertised. We report a longitudinal laboratory study on the use of a system known as Quikwriting. We have extended Quikwriting so that a stylus, a joystick, or a keyboard can be used as the input device. Twelve participants used the stylus and joystick modes of input in twenty 15-minute sessions. In the end their performance with the keyboard was tested to see if Quikwriting skill transfers to new devices easily. Quikwriting was found to be functional with all of the tested devices, but laborious to learn. The final text entry rates were 16.1 wpm with the stylus, 13.2 wpm with the joystick, and 6.1 wpm with the keyboard.
