Abstract: A method is provided. The method comprises a first step of acquiring wrist exercise information including at least one of orientation information and motion information of a wrist of a user, a second step of acquiring upper body exercise information including at least one of orientation information and motion information of a torso of the user, a third step of calculating, using reference wrist exercise information and reference upper body exercise information corresponding to each of a plurality of exercise types, a first similarity degree between the reference wrist exercise information and the wrist exercise information and a second similarity degree between the reference upper body exercise information and the upper body exercise information for each of the exercise types, and a fourth step of determining an actual exercise type performed by the user, among the exercise types, based on the first similarity degree and the second similarity degree.

Abstract: A rigidifiable flexible device includes a flexible member having flexibility, a plurality of movable members arranged in a line on a path between one end and the other end of the flexible member along a longitudinal direction of the flexible member, the movable members being movable on the path, a stopper provided at the one end of the flexible member and configured to prevent the movable members from being removed from the path beyond the one end of the flexible member, and a blocking member configured to prevent the movable members from being removed from the path beyond the other end of the flexible member. The length of a portion of the path between the blocking member and the stopper is adjustable so that the movable members are brought into close contact with each other on the path to form an integrated support body.
