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.
Claims22
A method for recognizing a motion performed using a gripped object, comprising:
- estimating a state of a wrist of a user, based on a first sensor configured to be disposed on the wrist of the user, according to a writing action performed using the gripped object;
- estimating a joint motion of a body part extending from the wrist of the user, based on a second sensor configured to be disposed on the wrist of the user, according to the writing action based on an electrical biomedical signal of the user;
- and
- estimating a state of the gripped object according to the joint motion and the state of the wrist,
- wherein the first sensor comprises an acceleration sensor and the second sensor comprises any one or any combination of any two or more of an electrocardiogram (ECG) sensor, electrooculogram (EOG) sensor, electromyogram (EMG) sensor, and electroencephalogram (EEG) sensor.
A motion recognition system performed using a gripped object, comprising:
- one or more processors configured to:
- estimate a state of a wrist, based on a first sensor configured to be disposed on the wrist of the user, according to a writing action performed using the gripped object;
- estimate a joint motion of a body part extending from the wrist of the user, based on a second sensor configured to be disposed on the wrist of the user, according to the writing action based on an electrical biomedical signal of the user;
- and
- determine a state of the gripped object according to the joint motion and the state of the wrist,
- wherein the first sensor comprises an acceleration sensor and the second sensor comprises any one or any combination of any two or more of an electrocardiogram (ECG) sensor, electrooculogram (EOG) sensor, electromyogram (EMG) sensor, and electroencephalogram (EEG) sensor.
