  • Patent number: 10791963
    Abstract: A method for measuring motions of a thumb and fingers, which can relatively easily measure angles at joints of a thumb and fingers within a limited space of the thumb and fingers, using a system that may be lightweight and compact enough not to hinder a natural motion of a hand. To this end, the method measures motions of a thumb and fingers of a user who wears a glove, and includes: attaching first ends of first and second flexible wires to positions of the glove respectively corresponding to middle and proximal phalanxes of each finger; connecting second ends of the first and second flexible wires to a sensing module so that the first and second flexible wires can move forward and backward while maintaining tension thereof in accordance with a motion of the finger; and by the sensing module, measuring moved distances of the first and second flexible wires, wherein rotary angles at corresponding joints in the thumb and fingers are calculated based on the measured moved distances.
    Type: Grant
