DIGITAL DEVICE AND METHOD FOR CONTROLLING THE SAME

摘要

A wearable device includes a bio signal sensor unit which senses a bio signal; a storage unit which stores data; and a processor which controls the bio signal sensor unit and the storage unit. The processor unit generates first reference data which includes the weight of the first reference object and the first bio signal in case of directing a first bio signal generated when a first reference object is held, generates measurement data which includes a second bio signal in case of directing the second bio signal generated when the measurement object is held, compares the measurement data with the first reference data, and obtains the weight of the measurement object.
