Abstract: A method and apparatus for motion capture interface using multiple fingers are disclosed. The method includes measuring a position of an end of a middle finger of an actual hand in a state in which the actual hand is spread, deriving a starting reference position of the middle finger of the actual hand, and calculating a length of the middle finger of the actual hand. The method further includes recognizing a relationship between starting reference positions of a thumb, an index finger, a middle finger, and a wrist based on using a virtual hand reference model that models a virtual hand to be controlled.

Abstract: Provided is a three-dimensional magnetic sensor based finger motion capture interface device, including a back-of-hand fixing member; a finger wearing member; at least one link member which is disposed between the back-of-hand fixing member and the finger wearing member and includes at least one magnetic sensor; at least one fixing member which connects between a plurality of link members; and a controller which receives sensor coordinate values corresponding to the change of a magnetic line of force sensed by the at least one magnetic sensor, extracts pitch and yaw motions of each link member based on the received sensor coordinate values, and calculates a user's finger position based on the extracted pitch and yaw motion values.
