A study on a ubiquitous system for collecting barrier-free information of evacuation centers for wheelchair users

摘要

In this short paper, we propose a ubiquitous system for automatically collecting information on the barrier-free level of evacuation centers and their access routes for wheelchair users by using a ubiquitous sensor node attached to the wheelchair. This sensor node uploads the data to a home server via a WiMAX network, and the home server infers the assessment level of the site. This information is associated with the location data in a cloud map service, and wheelchair users can access the information through their home server by using a handheld device.
