Implementation of effective onboard computer technologies into commercial cockpits will alter the current role and actions taken by pilots. These new technologies will require precise and efficient input methods due to the unstable nature of a cockpit environment. The benefits of haptic force feedback input devices have been shown in previous research. The present study investigated the effects of force feedback distractors on movement time, movement path, and workload. Results demonstrated that in the presence of distractors, resistive spring force levels most strongly influenced all dependent variables. Attractive gravitational force levels had no impact on movement times and minimal impact on distractor navigation strategy. The mouse, which had no force feedback, consistently showed the fastest movement times. Since prior research has demonstrated the benefits of attractive gravitational force feedback, and participants preferred to avoid distractors with high resistive spring force, significant design implications are discussed.
