Abstract
Providing parents with information related to child's injury has been considered to be a useful method for preventing child's injuries for many years. However, statistics on child's injuries shows that conventional methods failed to reduce injuries. One cause lies in the lack of feedback loop for personalizing information. In this paper, the authors describe“an information circulation system, ”which collects information on parents' cognition on child's injuries through offering personalized information in parallel. This paper describes a new service which offers injury scene videos on the web for injury prevention as a concrete example of the information circulation system. The feasibility of the new service is confirmed by conducting experiments on web for over 13 months in cooperation with a company. This paper also proposes a new method for personalizing information by selecting optimal videos on the web content service based on feature values describing injuries. The effectiveness of the proposed method is proved by questionnaire survy for 20 parents.
