The purpose of this study is to develop an evaluation index for the lateral reaching motion of elderly people using a simple measurement system with RGB-D sensors. Physical therapists often evaluate the motor function of elderly people visually. Therefore, if we can quantitatively evaluate motor functions, it is expected to reduce the workload of physical therapists and to allow elderly people to measure their own motor functions. In this study, we use DTW to extract features from time series data of movements. We propose an index that focuses on whether a person is able to perform actions equivalent to those of a healthy person by making judgments using the MT method based on the actions of a healthy person from multiple motion features.
