Abstract
We propose the running repeat function for operation support of an electric wheelchair. When using an electric wheelchair indoors, forward movement operation is easy, however backward motion operation is difficult. In such a situation, a running repeat function is useful as the backward-motion operation support method. This function is how to carry out an autonomous running by recording the running data at the time of forward movement, and reverse-playing back the data. The control method of this function was established by our studies. However, passenger of the Autonomous Wheelchair is dangerous if there is no information presentation of the next operation. Therefore, in this paper, it verifies by experiment about the timing of information presentation.
