In the case of loss of sight sense due to the sight function trouble, user meets the difficulty for capturing surrounding information and doing self-walking. Up to now, our research group has enabled the indoor walking assistance by extracting distance information from a surrounding situation and converting it into the sense of touch signal. However, it was pointed out not to be able to understand a surrounding situation because a existing walking assistance system transmitted only distance information (obstacle contact information), and to give mental uneasiness to the user. This research proposes the system that feeds back and transmits information that classifies the situation and the object roughly by using the stereoscope as surrounding situations other than the distance. This presentation reports the technique for improving the estimated distance precision by setting error level that is included the fluctuation for the image noise in this presentation.
