Quantitative evaluation of body-sway caused by tactile apparent movement

The recognition of tactile apparent movement is normally a subjective sense. However, when applying tactile apparent movement to an engineering system, quantitative evaluation is necessary. In a previous study, we examined the body-sway caused by tactile apparent movement under fixed experimental conditions, but the body-sway characteristics were not fully investigated. In this study, we investigated the body-sway caused by tactile apparent movement under fixed experimental conditions. We focused on biological information and body-sway, and compared cases where the apparent motion was recognized and not recognized. Our findings will help to improve the performance of systems that use tactile apparent movement. © 2011 International Symposium on Artificial Life and Robotics (ISAROB).
