Evaluation of a new sensor system for ambulatory monitoring of human posture and walking speed using accelerometers and gyroscope

Measurement of physical activity is one of the key subjects in the fields of rehabilitation and gerontology. From this point of view, we have been developing portable devices for monitoring human posture and walking speed in ambulatory subjects. In this paper, a new sensor system using three accelerometers and one gyroscope was developed, and its availability was evaluated.
