| 摘要： | A considerable body of knowledge exists regarding the influence of whole-body motion on the control behavior and task performance of a vehicle operator required to compensate for the effects of unexpected external disturbances. The research described was conducted to determine whether similar effects would be observed if the motion information were tactually displayed through the seat pan, rather than in a whole-body motion environment. The experiment was designed such that the transfer of training from a tactual dynamic seat display to a whole-body motion environment could also be evaluated. The experimental task required subjects to regulate for a random-appearing, roll-axis disturbance in a simulated vehicle having aircraft-like dynamics. A centrally located compensatory display, subtending about nine degrees, provided visual roll error information. Control inputs were made via a right side-arm isometric controller. The two-phase experiment included a training phase and a criterion phase. During training, subjects tracked under conditions of either visual information only, visual plus tactual seat cues, or visual in the one-to-one motion environment. Following training, all subjects were transitioned into the criterion whole-body motion environment. The data clearly demonstrate that a dynamic seat pan can effectively impart motion information, but the device (as used in this experiment) did not effectively train subjects to properly interpret and use the motion information available in the whole-body motion environment. |
