US 7,843,323 B2 · Method and system for recognizing daily activities using sensors

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.

A daily activity recognition system using sensors, the system comprising:

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,
wherein the daily activity recognition unit comprises:
a candidate daily activity recognizer checking contents of the basic activities stored in the buffer management unit for each point in time previously set and extracting candidate daily activities by using the checked contents;
and
a plurality of daily activity recognizers recognizing the daily activities of the old person, corresponding to the basic activities included in the extracted candidate daily activities.

receiving data measured by a plurality of sensors installed in required positions in a home in real time;
recognizing a corresponding sensor transmitting the received data and converting the received data into a basic activity corresponding to the recognized sensor;
storing the received basic activity received from a radio frequency (RF) management unit, in an internal buffer;
recognizing the daily activities of the old person based on the basic activity stored in the buffer for each present point in time;
and
storing the recognized daily activities in a database.
wherein the recognizing the daily activities of the old person for each preset point in time comprises:
checking contents of the basic activity stored in the buffer, for the each preset point in time;
extracting candidate daily activities by using the checked contents;
and
recognizing each of the daily activities of the old person, corresponding to a basic activity included in the extracted candidate daily activities.
