Abstract
This study was performed to determine how keyboard geometric differences at angles of 5°, 10°, 15°, and 25° affected user keyboard performance. Sixteen participants typed from hard copy stimulus material to an IBM Datamaster (System/23). One-way analysis of variance with repeated measures produced no significant performance differences. Participants reported the keyboard uncomfortable at 5° and 25°. Participants reported no difference between the 10° and 15° positions (p <.05). The authors recommend a range of 10° to 18° for fixed sloped keyboard and 10° to 25° adjustment range for a flexible keyboard.
