Outline of Final Research Achievements

In this study, we are focusing on the realize an indoor monitoring using plants. Previous results have shown that the area which plants can detect human movement is narrow. Therefore, in this study, we investigated an algorithm for monitoring by using multiple plants. Estimating each plant installed in the room, and aggregating the results.
As a result of the study, it was found that CNN is effective as an estimation model and that it is better to estimate human movement by aggregating the measured data than by estimating individual plants. However, since aggregation has the disadvantage that it has problems on the increase of the number of plants or the computational cost. On the other hand, estimating individually has the advantage for such problems. However, it has the requirement to improve accuracy are needed in the future.

Academic Significance and Societal Importance of the Research Achievements

高齢者社会の進行により、室内モニタリングの需要は高まっているが、センサによって監視されることへの心理的抵抗は高い。本研究では、植物をセンサとして用いることで、心理的な抵抗を減らした室内モニタリングの実現を目指している。現時点では、植物センサの性能は不十分であるため、精度の高い学習手法や複数のセンサを有効に組み合わせて利用する方法の検討を行った。研究成果は、植物を用いた実用的な室内モニタリングの実現の指針となり、さらなる高齢化社会に対して有効であると言える。
