Method, device, and non-transitory computer-readable recording medium for extracting biosignal data

A device for extracting biosignal data, the device comprising:

• a connection status determination unit configured to determine whether a data extraction device is connected to a data collection device;
• and
• a data path management unit configured to, in response to determining that the data extraction device is not connected to the data collection device, determine to establish a data storage path which allows biosignal data collected by the data collection device to be stored in a memory of the data collection device via a microcontroller (MCU) of the data collection device, and in response to determining that the data extraction device is connected to the data collection device, determine to establish a data extraction path which allows an interface of the data extraction device to directly connect to the memory of the data collection device not via the MCU of the data collection device.
