Abstract
A device, a method, and a system recognize a motion using a gripped object. The motion recognition device may estimate a state of a wrist of a user according to a writing action using the gripped object and may estimate a joint motion of a body part related to the wrist according to the writing action. The device may then estimate a state of the gripped object according to the state of the wrist and the joint motion. Additionally, the motion recognition device may control an external device by using a control signal generated by continuously tracking the state of the object.
Claims31
A method for recognizing a motion performed using a gripped object, comprising:
- estimating a state of a wrist of a user according to a writing action performed using the gripped object;
- estimating a joint motion of a body part of the user related to the wrist according to the writing action;
- and
- estimating a state of the gripped object according to the state of the wrist and the joint motion.
A device for recognizing a motion performed using a gripped object, comprising:
- a wrist state estimator configured to estimate a state of a wrist according to a writing action performed using the gripped object;
- a joint motion estimator configured to estimate a joint motion of a body part of the user related to the wrist according to the writing action;
- and
- an object state estimator configured to estimate a state of the gripped object according to the state of the wrist and the joint motion.
A system for recognizing a motion using a gripped object, comprising:
- a motion recognition device configured to estimate a state of a gripped object according to a state of a wrist of a user and a joint motion of a body part related to the wrist, and configured to transmit a control signal for controlling an external device, the control signal generated by continuously tracking the state of the gripped object;
- and
- the external device configured to perform a predetermined operation corresponding to the control signal when receiving the control signal.
A method for recognizing a motion using a gripped object, comprising:
- estimating a state of a gripped object according to a state of a wrist of a user and a joint motion of a body part related to the wrist;
- storing a shape generated by continuously tracking the state of the gripped object;
- recognizing the shape to identify an external device corresponding to the shape and to determine an operation to be performed by the external device;
- and
- transmitting a control signal to the external device to instruct the external device to perform the operation.
