Abstract: This paper proposes a new methodology for identifying barriers encountered by wheelchair users in daily life spaces. Currently, barrier-free designs are required not only for newly constructed buildings, but also when renovating existing facilities and public spaces. It is often difficult for administrators to envisage the full reality of barriers in their facilities because potential obstacles can be created inadvertently by a variety of objects that have complicated three-dimensional (3D) geometries. Our approach aims to capture the overall dimensions of target spaces by collecting and combining depth images taken using a hand-held RGB-D camera (also commonly referred to as a ranging camera), and then to navigate a virtual wheelchair through the target space in a computer simulation to check out possible obstacles. Our simulation employs a motion planning technique, considering not only the size and the volume but also mobility of the wheelchair to detect potential obstacles. The experimental results of our method showed effective functionality in terms of practicality and usability.
