This paper proposes a method for predicting human posture by thermal array sensors. In our previous work, we studied a system for estimating human posture by the sensors. The system successfully estimated human posture for elderly people living in a nursing home. As a further step to our previous work, this paper presents a human posture prediction method using Bayesian inference with the sensors...
This paper describes a framework of blood pressure variation factor analysis. We design a system in order to support improving our lifestyle habit. The system classifies subjects into several variation groups in order to evaluate a personal characteristic of blood pressure change. Furthermore, we describe a blood pressure seasonal variation evaluation method by using normalized cross-correlation coefficient...
This paper proposes a human movement trajectory recording method by a thermopile array sensor. In the system, the sensor is attached to the ceiling and it acquires place-dependent temperatures, which is called thermal distribution. The system obtains 4 × 4 pixels thermal distributions from the sensor. The distributions are analyzed to extract human movement trajectory. First, human candidate pixels...
