ABSTRACT

For people with disabilities, some everyday tasks and situations can present physical constraints very hard to be overcome by them. In this case, wheelchairs are standard devices that can help them increase their locomotion ability and life quality. However, it is very difficult for a

for People with

wheelchair user to plan the necessary movements in a place never visited before. These difficulties are mainly due to the lack of accessibility information [1] ensuring that there is a possible way for a wheelchair to go from the entrance to a desired location in a building. For outdoor navigation, a common solution [2] [3] [4] is the use of high-precision systems and databases like GPS (Global Positioning System) and GIS (Geographic Information System). The intention is to provide a navigation system to wheelchair users that could display, in real time, accessibility information that allows a safe motion between locations in open environments.
