A Fundamental Study of Tool Embodiment for Human Dynamic Analysis Relating to Handling and Stability of Driving

Article of Honda R&D Technical Review Vol.27 No.1

Summary

In the course of formulating methods for evaluating the handling and stability of driving an automobile, attention was focused on embodiments of the size of the automobile and its movements, which the operator absorbs into his or her own sensorimotor system. An experiment was devised to clarify the relationship between embodiment and sensorimotor activity. The experiment involved cutting paper with scissors in a virtual reality environment, where that action would be considered equivalent to steering an automobile from the perspective of processing sensorimotor system information.
In a virtual reality environment, the sensory quantity that accompanies activity is provided to the operator as feedback information. When this information was changed in various ways, the corresponding changes that occurred in the cerebral blood flow clarified the relationship between the feeling of actual operation generated during operation and the activity of the central nervous system. It was also found that the feeling of actual operation requires an appropriate sensory quantity to be presented, and that time delay in presenting the sensory quantity alters the feeling of actual operation. This experimentation during the manipulation of tools produced results that led to new ideas regarding evaluation of the handling and stability of driving of automobiles from the perspective of embodiment. In other words, it led to the proposal that it is necessary to evaluate the sensory information generated during driving.
