Deriving Cursor Control Device Expectations for the Orion Crew Exploration Vehicle

Given the proliferation of touch-sensitive screen technologies, the factors contributing to efficiency of cursor control device were examined to better inform choice and design of Graphical User Interfaces. Fitts' law can be used to describe the relative efficiency of these cursor control devices. Experiment One required 18 participants to move a cursor between targets depicted upon a WACOM PL400 display graphics tablet, over various amplitudes, using a computer mouse or stylus, examining the speed and accuracy of cursor placement. The touch sensitive screen allowed faster acquisition of targets than the mouse. Since the mouse has a higher control/display ratio (gain) than the touch sensitive screen, Experiment Two addressed manipulation of the gain settings on computer mouse performance. Low gain offered some accuracy benefits. Possible posture problems associated with the touch sensitive screen were explored in Experiment Three. Screen orientation had little effect upon cursor positioning performance, suggesting the benefits of the touch sensitive screen can be transferred to user-friendly postures.

And Task

The primary aim of training is to improve performance. Part-task training may be the more economical method, because full mission training simulators often cost more than the vehicles they simulate. However, the skills learned may not transfer effectively to performance of the complete task. This study investigated the effectiveness of Part-task training on the psychomotor portion of a supervisory control simulation. Twelve subjects were divided into Part-task and Whole-task groups and told to perform the task as quickly as possible. Part-task training was provided with the cursor-control device (a magnetic pen and pad), prior to transition to the Whole-task. Some distinct advantages of the Part-task training were: (1) The Part-task group learned the task faster; (2) The Part-task group's scores and task times continued to improve, while the Whole-task group's did not; and (3) A significant increase in speed of response for the Part-task group and almost no improvement in speed for the Whole-task group.
