Development of the Estimation Method of Resident's Location Using Bioelectric Potential of Living Plants and Knowledge of Indoor Space

摘要

In Japan, an aging society is progressing rapidly, and the number of aged single-person households are also increasing. Therefore, to ensure residents' safety, a demand of monitoring is increasing. Generally, microphones or cameras are used for monitoring, however, it is hardly accepted to residents because their privacy will be violated by such devices. In this paper, we focused a living plant as a monitoring device. Living plants are easily accepted to residents. Furthermore, they have a property at bioelectric potential of a living plant will change affected by an activity of human around the plants. Moreover, according to the change of the potential, it is able to estimate a distance or a kind of activities of human. Therefore, we have studied to develop a method to use living plants for monitoring. However, we have found that monitoring by living plants has problems of an accuracy and a measuring distance. In this paper, we develop a monitoring method using living plans and a knowledge base of indoor space. The knowledge contains a layout structure of the space. Using both living plants and the knowledge base, we propose an improved monitoring method. And then, we report a result of experiment to confirm an accuracy of the method integrated content of the abstract in your paper should include the brief introduction of research intention, method, result and conclusion.
