Headset apparatus for detecting multi-biosignal
First Claim
1. A headset apparatus for detecting a multi bio-signal, comprising:
- a headset body configured to be mounted on a head of a user;
a plurality of electrodes which are exposed on an outer surface of the headset body so as to be in contact with a forehead of the user when the headset body is mounted on the head of the user;
a brainwave detection sensor embedded in the headset body, and configured to detect a brainwave signal based on a signal detected by the plurality of electrodes;
a heartbeat detection sensor extending from the headset body through a signal cable, and configured to be mounted on an ear of the user to detect a heartbeat signal; and
a headset controller configured toanalyze frequencies of the brainwave signal to extract an alpha wave and a beta wave,calculate a brainwave stress index based on the alpha wave and the beta wave,calculate a heartbeat stress index based on a variation of an R-peak interval of the heartbeat signal,respectively apply predetermined weight factors to the brainwave stress index and the heartbeat stress index to generate a weighted brainwave stress index and a weighted heartbeat stress index, andadd the weighted brainwave stress index and the weighted heartbeat stress index to calculate a complex stress index.

Abstract
The invention relates to a headset apparatus for detecting a multi bio-signal comprising: a headset body configured to be mounted on a user'"'"'s head; a plurality of electrodes which are exposed on an outer surface of the headset body so as to be in contact with a forehead of a user when the headset body is mounted on a user'"'"'s head; a brainwave detection unit which is embedded in the headset body and which detects a brainwave signal based on a signal detected by the plurality of electrodes; a heartbeat detection module which extends from the headset body through a signal cable and which is configured to be mounted on a user'"'"'s ear to detect a heartbeat signal; and a headset controller to determine a complex stress index based on the brainwave signal detected by the brainwave detection unit and the heartbeat signal detected by the heartbeat detection module. Accordingly, the apparatus can measure a user'"'"'s stress index accurately by measuring a multi bio-signal such as a brainwave and can be manufactured in the form of a wearable device.
