Abstract:
1. A method for analyzing stress, the method comprising the steps of: generating bio-signal pattern information upon periodically receiving a bio-signal from a plurality of bio-signal measuring devices each connected to one of a plurality of unspecified individuals; receiving an answer to each of a plurality of questions for checking a stress level, said questions being provided to each of the unspecified individuals in accordance with at least one physical characteristic of the unspecified individuals; forming a reference information collection for stress analysis based on the bio-signal pattern information corresponding to the unspecified individuals and the answers received, wherein the reference information is classified according to criteria associated with characteristics of the unspecified individuals; receiving bio-signal pattern information from one of the plurality of bio-signal measuring devices connected to a specified user, wherein the bio-signal pattern information of the specified user is determined from a plurality of bio-signals obtained from the one of the plurality of bio-signal measuring devices over a predetermine period; determining, by a processor, a reference information from said reference information collection, said determined reference information substantially matching the bio-signal pattern information from the one of the plurality of bio-signal measuring devices connected to the specified user, said determined reference information being associated with at least one characteristic associated with the specified user; and determining, by the processor, a stress level corresponding to the bio-signal pattern information of the specified user based on the determined reference information, for display.
