Wearable walking care checking gait device using the AHRS sensor

Abstract

This paper presents implementation of an attitude and heading reference system (AHRS) based on detachable gait detection device. Recent research has focused on measuring and taking feedback from the gait. However, there is a lack of research on the convenience of the user. So, a detachable gait detection device considering the user's view is proposed. Unlike, traditional insole type sensors, which are applied only to the running shoes. This study makes it possible to apply it, to various shoes other than specific purpose shoes. In particular, we have studied algorithms that can measure various values like gait type, number of steps. That values measured only by the sensors, built in insole, but now we can use detachable type outside the shoe. This algorithm can be used in a straight line as well as any type of pattern you encounter in everyday life. Experiments to prove the performance and accuracy of this algorithm were carried out like, for classifying different walking styles and measuring steps. It is possible to recognize unusual behavior of tread without going to the hospital through this device, and it will reduce the cost and psychological burden of consumers.
