Abstract
From the previous researches, it was found that there is a relationship between the body part motion and the body acceleration trend of crutch users. Based on the finding, an estimation method of the body acceleration trend was proposed. In this paper, the previously proposed estimation method was applied for several participants' crutch walks where a Kinect sensor and an accelerometer were used for measurements of the body part motion and the body acceleration of the participant, respectively. As a result, it was confirmed that the trend of the body acceleration can be estimated from the body part motions that were measured by the Kinect sensor. Finally, a prototype application software for an instruction for crutch users was developed, and it was achieved that the developed software could instruct the crutch users in proper crutch walk motions right after measurements.
