Abstract
There is provided a daily activity recognition system using sensors installed in required positions in a home to recognize daily activities of an old person, the system including: a radio frequency (RF) management unit receiving data measured by a plurality of sensors installed in required positions in a home, recognizing a corresponding sensor transmitting the received data, and converting the received data into a basic activity corresponding to the recognized sensor; a buffer management unit storing the basic activity received from the wireless processing manager in an internal buffer; and a daily activity recognition unit recognizing daily activities of an old person at each point in time previously set, based on the basic activity stored in the buffer. The daily activities of the old person are recognized and stored in a database, thereby providing various services related to the health of the old person.
