Apparatus and a method for recognizing an activity of daily living
First Claim
Patent Images
1. An apparatus for identifying an activity of a moving subject, the apparatus comprising:
- a radio frequency identification (RFID) reader for identifying a motion object separate from the moving subject by reading an RFID tag attached to the motion object;
a motion detector attached to the moving subject for identifying a motion characteristic of the moving subject by detecting acceleration of the moving subject; and
a controller for identifying the activity of the moving subject based on an identity of the motion object received from the RFID reader and a type of motion of the moving subject, the controller configured to identify the activity by;
classifying the motion characteristic received from the motion detector into a motion type in predetermined motion type classes; and
recognizing the activity responsive to the classified motion type and the identified motion object satisfying a predetermined relationship.

Abstract
Provided is an apparatus for recognizing an activity of daily living (ADL). The apparatus includes a radio frequency identification (RFID) reader for reading the information of an RFID tag to recognize a motion object, a motion detector attached on a moving subject for acquiring acceleration information and recognizing a motion characteristic, and a controller for receiving information on the motion object from the RFID reader and information on the motion characteristic from the motion detector and then recognizing an ADL.

4. A method for identifying an activity of a moving subject, the method comprising the steps of:
-
identifying a characteristic of a motion by detecting acceleration of a moving subject, comprising; determining motion of a lower part of the moving subject; and determining motion of an upper part of the moving subject; identifying a motion object by reading information from an RFID tag attached to the motion object, the moving subject separate from the motion object; and identifying the activity of the moving subject based on the identified motion characteristic and the identified motion object, comprising; classifying the motion characteristic into a motion type in predetermined motion type classes; and recognizing the activity responsive to the classified motion type and the identified motion object satisfying a predetermined relationship. - View Dependent Claims (5)
