Abstract:
Technology for transmitting and receiving a biosignal based on a pattern related to the biosignal and a feature point included in the biosignal. A biosignal transmitter includes a biosignal obtaining unit configured to obtain a biosignal comprising a plurality of unit signals, a parsing unit configured to parse the biosignal to extract a first unit signal of the plurality of unit signals, a pattern obtaining unit configured to obtain a pattern related to the biosignal based on the first unit signal, and a transmitting unit configured to transmit information related to a feature point of the first unit signal based on the first unit signal and the pattern.
Abstract:
A headset device includes a headset body, a connection unit to move relative to the headset body, and a sensor unit having a light emitting element and a light receiving element to sense a biosignal, the sensor unit mounted to the connection unit to make contact with a human body. The sensor unit may measure a biosignal of a user, and the headset body and the sensor unit are indirectly connected by the connection unit. Accordingly, the sensor unit may be isolated from movement or vibration received through the headset body.
