Comparison of Four-Cursor Buttons vs Joystick to Access Computerized Technical Information from an Integrated Maintenance Information System
Abstract
The purpose of this thesis was to evaluate the use of four-cursor buttons versus a joystick device to present technical order information on a portable maintenance aid computer for aircraft technicians in a maintenance environment. Studies to date have verified the superiority of computer-presented technical orders when compared to current paper-based systems; this research investigated the effectiveness of these computer-based systems when technicians used a joystick or four-cursor button to display desired technical information. A comparison was made as to technician performance using a portable maintenance aid at the 4950th Test Wing, WPAFB OH. A total of thirty-two maintenance technicians accessed and displayed technical information using a joystick device and the four-cursor keys. Results indicated no statistically significant difference in the performance of maintenance technicians when using either access device in a controlled environment. The major conclusion was that either access device may be a viable answer for use in the flight line environment. The chief recommendation is that further studies be performed using a different joystick device and computer software that supports the eight joystick functions....
