A FINGER MOTION MEASUREMENT SYSTEM AND MEASUREMENT METHOD OF FINGER MOTION

摘要

The present invention relates to a system and a method to measure a finger motion, the method capable of easily measuring a joint angle of a finger despite a limited space of the finger, and being small enough to avoid the interruption of the natural movement of a hand. To achieve the purpose, the method to measure a finger motion of a user wearing gloves includes a step of attaching an end of each of first and second flexible wires to a position on the gloves corresponding to each of middle and proximal phalanxes; a step of connecting the other end of each of the first and second flexible wires to a sensing module so that each of the first and second flexible wires is able to move forward and backward in accordance with finger motion while keeping tension; and a step of measuring a movement distance of each of the first and second flexible wires through the sensing module. A rotation angle of a corresponding joint in the finger is calculated based on the measured movement distance.
