Estimation of anxiety at utilizing wheelchair by measuring brain waves in the case of going down slopes using wheelchair

Abstract

In this paper, we examine the anxiety at utilizing wheelchair. When the human use wheelchairs, from the influence of environment, the human feel a sense of unease. In particular, when the human go down slopes using wheelchair, the human feel anxiety if the angle of slope is greater than thresholds, which is different depending on the person. If thresholds can estimate, we have possibility to make wheelchairs using which no one feels the anxiety. However the problem to estimate the threshold of angle to feel the anxiety is difficult. In this paper, we propose an estimation method of angle of threshold to feel the anxiety by using brain waves of the human in the case of going down slopes using wheelchair.
