Implementation of prototype mobile application operated on smartphones for micromedia service

Many people were injured or otherwise suffered during evacuation or on their way home in the Greater Tokyo Area during the 2011 East Japan (Tohoku) Earthquake. One lesson from this disaster was that they had to decide what was best based on their individual attribute. However, we have no supporting tool for them to decide their appropriate behavior, so we designed and developed an information provision system, based on a micromedia concept, that features (i) using logs of their location logs, and (ii) introducing spatial data mashup method to abstract information based on individual user needs. We then implemented our prototype application and got reviews from 64 users. As the result of evaluation to our system from 64 users, most of them accepted the concept of micromedia, but pointed out issues about spatial layers management, personal information treatment and how to express information.
