Mobile MultimediaAbstract
Faced with the rapidly aging population, shrinking number of caregivers, and the promise of economic returns, the growing demand to provide more service assistance to handicapped persons and the elderly is a challenging task. In Japan, there are about 560,000 people who are in wheelchairs but they are rarely seen in public. One reason is that, they lack the information on the available facilities that cater to their needs once they go out to their destination. Providing these people with information on barrier-free facilities and other related information along their route will help boost their morale, build self-confidence, and selfreliance. In this paper, we describe the development towards a real-time and lightweight location-aware navigation service, called NaviLite, with particular focus on people in wheelchairs. We utilized the readily available handheld PHS mobile phone devices to display the location map, obstacles and danger zones within the periphery, and the suggested route to their destinations. We conducted preliminary experiments and discussed its results. Key words: wireless mobile computing, location-aware, navigation service, barrier-free facilities
