Abstract: A method and a system for motion comparison, especially for functions of a multimode motion streaming comparison, are provided. The method includes: obtaining a streaming motion and nodes of a user according to images of the user; providing a streaming motion and nodes of a virtual coach; calculating relation values between coordinates of the nodes of the user and those of the virtual coach according to a streaming node comparison algorithm; obtaining weights via a weighting vector according to parts of body, exercise types and time information; generating a comparison result according to a result of the weights respectively multiplying the relation values; mapping the comparison result to a similarity value. Therefore, a continuous motion compliance of individual trained parts of body of the user is improved, and the correctness for the user to fathom postures is improved effectively.

Abstract: A rehabilitation coaching method and a rehabilitation coaching system are provided. The method includes setting an exercise rhythm according to personalized exercise rhythm data for the user, and outputting the exercise rhythm to coach the user to do a rehabilitation exercise. The method also includes obtaining a total oxygen consumption rate according to the profile of the user, the time of doing the rehabilitation exercise and the exercise rhythm, and obtaining an exercise intensity according to the resting heart rate of the user and an average heart rate of the user during the rehabilitation exercise. The method further includes obtaining a recommended exercise rhythm according to the exercise intensity and the total oxygen consumption rate, and updating the personalized exercise rhythm data for the user according to the recommended exercise rhythm.
