a touchscreen, is supported by these studies. The first phase of the current experiment compares three monitor positions chosen based on previous research, 30”, 45”, and 75”f rom horizontal (75” is approximately the standard monitor position), for perceived fatigue and user preference.T he hypothesis is that the 30” angle wifl result in less fatigue and be preferred by users.

N2 - The study explored touchscreen keyboards using high precision touchscreen strategies. Phase one evaluated three possible monitor positions: 30°, 45°, and 75° from horizontal. Results indicate that the 75° angle, approximately the standard monitor position, resulted in more fatigue and lower preference ratings. Phase two collected touch bias and key size data for the 30° angle. Subjects consistently touched below targets, and touched to the left of targets on either side of the screen. Using these data, a touchscreen keyboard was designed. Phase three compared this keyboard with a mouse-activated keyboard, and the standard QWERTY keyboard for typing relatively short strings of 6,19, and 44 characters. Results indicate that users can type approximately 25 words/minute (wpm) with the touchscreen keyboard, compared to 17 wpm using the mouse, and 58 wpm when using the keyboard. Possible improvements to touchscreen keyboards are suggested.
