| Outline of Research at the Start |
This research is to design and develop smartphone based personal disaster evacuation systems using LBS and AR on disaster maps, to protect people’s lives when disasters happen. The system will be able to work under harsh environment in disasters such as disconnection of the internet and black-out.
|
| Outline of Final Research Achievements |
The research succeeded in developing algorithms and mobile applications to combine analogue disaster maps with Location-based Services (LBS), which enables functions including positioning, searching and navigation on conventional analogue maps. This technology makes it more convenient for foreigners who does not understand Japanese for traveling and evacuation by local thematic analogue maps.
Beside outdoor positioning by GNSS, the research also explored solutions for indoor positioning, where GNSS cannot be used. The research succeeded in developing algorithms and applications which enable AR-enhanced indoor positioning. The research explored visual-based infra-free positioning technology, which achieved advantages of high positioning accuracy, low cost and user-friendly AR visualization. It is very useful in underground shopping streets and subway stations.
