Tag device for recognizing motion, motion recognizer, and method of operating the tag device

A motion recognizer comprising:

• a memory storing a program;
• and
• at least one processor configured to execute the program to:
• receive time information of a tag device from a first sensor and generate first position data of the tag device, the first position data comprising position values at a plurality of points in time included in an operation period,
• receive first speed data of the tag device from a second sensor, the first speed data comprising acceleration values at the plurality of points in time and generates second position data of the operation period based on the position data and the first speed data,
• generate an image based on a path of movement of the tag device based on the second position data of the operation period, and
• classify the image into one of a plurality of movements by using a trained neural network model.

A method of operating a tag device, the method comprising:

• receiving time information of a tag device from a first sensor and generate first position data of the tag device, the first position data comprising position values at a plurality of points in time included in an operation period,
• receiving first speed data of the tag device from a second sensor, the first speed data comprising acceleration values at the plurality of points in time and generates second position data of the operation period based on the position data and the first speed data,
• generating an image based on a path of movement of the tag device based on the second position data of the operation period, and
• classifying the image into one of a plurality of movements by using a trained neural network model.
