The purpose of my work was to limit the spread of the wheelchair accident by using the information and communication technology (ICT). This paper presents the changing situation of the seating pressure distribution on wheelchair users by variations in the gradient of the road surface. The measurement experimentation of seating pressure distribution was recording the traveling state of a wheelchair using both an acceleration sensor and an angular velocity sensor. To estimate the effect of changing the attitude of an occupant by a change in slope surface state and to cope with the improving safety. As a result, the traveling on the slope wasfound to have effects on the more than about average 7 times in the variation in pressure distribution from front-back direction in comparison to traveling on the flat road. In conclusion, the results of the study can be used to support maintenance of posture by wheelchair users.
