Exposure of a driver to vehicle vibration is known to disrupt manual performances, and more specifically affect the speed and accuracy of reaching tasks associated with vehicle operation. The effects of whole body vibration (WBV) can be analyzed as a function of the vibration characteristics of each body link. This information can then be used to identify movement strategies and predict biodynamic responses. Conceptual principles derived from the understanding of human behavior in a vibratory environment can then be used for the design of controls or interfaces adapted for vehicle operation in this context. The transfer functions of individual upper body links were estimated to investigate their biodynamic properties as a function of vehicle vibration frequency and spatial location of targets to be reached. In the present study, fourteen seated participants performed pointing movements to eight targets distributed in the right hemisphere. WBV generated by a ride motion simulator (RMS) consisted of vertical and horizontal sinusoidal displacement of a vehicle cab at 2 Hz, 4 Hz, or 6 Hz. The results obtained for a subset of experimental conditions (vertical vibration, 5 selected targets) show that the transfer functions of the torso, upper arm, and lower arm-hand vary as a function of vibration frequency and target location.
