Future cockpits are going to require new onboard technologies (e.g., Cockpit Display of Traffic Information, CDTI) in order to accommodate the responsibilities likely to be delegated to pilots under NextGen. The current study investigated the effects of multiple levels of force feedback on operator performance in a task designed to approximate a CDTI environment. Participants were presented with two different types of force feedback (gravitational and spring force feedback), each with multiple levels of gain. Approach Time, Time Inside Target and Overall Movement Time were recorded. Results demonstrated that the two highest levels of gravitational force significantly reduced Overall Movement Times and Approach Times relative to the lowest level of gravitational force. The two highest levels of gravitational force, however, resulted in largely similar performance and were found to be comparable to performance with a computer mouse. Spring force level only had a main effect on Time Inside Target.
