Abstract

The present invention relates to technology for realizing collaboration between bio-signal measurement devices used for personal health care. In a method of realizing collaboration between bio-signal measurement devices, connection to a plurality of bio-signal measurement devices for measuring bio-signals from a user is made, and a plurality of pieces of bio-signal data is received from the bio-signal measurement devices. First features are calculated from respective pieces of bio-signal data. Data required for calculation of second features is selectively received from the calculated first features, second features are calculated. The calculated first and second features are normalized, and the normalized first and second features are transmitted to at least one application program.
