WEARABLE DEVICE AND METHOD FOR MEASURING BIOMETRIC INFORMATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17991214 titled 'WEARABLE DEVICE AND METHOD FOR MEASURING BIOMETRIC INFORMATION
Simplified Explanation
The abstract describes a wearable device that includes sensors and processors to acquire and analyze physiological signals from a user's body. The device uses a light-emitting and light-receiving sensor to acquire a photoplethysmography (PPG) signal and an electrode sensor to acquire an electrocardiography (ECG) signal. The device then compares the PPG and ECG signals to determine an inter-beat interval calculation model. Using this model, the device can measure the inter-beat interval of the user from subsequent PPG signal data.

Original Abstract Submitted
A wearable device is provided. The wearable device includes a first sensor having a light-emitting part and a light-receiving part, a second sensor having at least one electrode, and at least one processor electrically connected to the first sensor and the second sensor, wherein the at least one processor acquires PPG signal data by using the first sensor for a first time while the wearable device is worn on a user's body, acquires ECG signal data by using the second sensor for the first time for which the PPG signal is acquired, determines an inter-beat interval calculation model, based on the result of a comparison between the PPG signal data and the ECG signal data, and acquires, based on the determined inter-beat interval calculation model, an inter-beat interval of the user from PPG signal data measured for a second time after the first time.
