Embodiment Construction

[0026] The present invention relates to a wearable device, which is used to wear on a person's body, such as a wristband, a wrist watch or a sports bracelet. The wearable device includes sensors to sense health data, such as heart rate , breathing, steps, etc. Therefore, through the wearable device worn on the wrist of the person, it can be used to monitor heart rate, observe sleep status, record exercise data and other functions. A powerful wearable device can be used as a payment tool, where near-field communication chips (near-field communication, NFC), radio frequency identification chips (radio frequency identification, RFID) or others can be set to transmit payment information to another device to perform financial transactions. In another example, the wearable device can display payment credentials, such as a 1D barcode or a 2D barcode (such as QR Code), allowing a specific scanning tool to read the payment information to perform financial transactions.

Abstract

The invention relates to a wearable device and a method for performing a registration procedure therein. The wearable device comprises a light source, a light sensor and a microcontroller for performing the method. In the method, the light source is started to emit detection light, and then the light sensor senses reflected light. The light intensity of the reflected light is then calculated. At this time, a registration value is generated according to the light intensity, and particularly, detection light of a frequency is registered as the registration value as a basis for determining whether the wearable device is properly worn on the human body. For example, when a wearable device may be worn on a person's wrist, the registration value is used to detect whether the wearable device has been distanced from the person's wrist.

Description

technical field [0001] The present invention relates to a wearable device, and in particular to a method and a device for performing a registration process by generating a registration value of the wearable device according to the measured light intensity. Background technique [0002] As more and more people practice a health-conscious lifestyle, various wearable health monitoring devices are sold on the market to monitor people's health data on a regular basis. A wearable health monitoring device can be worn on a person's body, such as a person's wrist, so when the device is worn on the wrist, the device is used to sense the person's health data. [0003] For example, a wearable health monitoring device uses a light source to shine on the skin of a person's wrist, and then uses a light sensor to sense the reflected light reflected from the wrist to collect health data. Health data such as heart rate can be sensed by using the wearable health monitoring device to read the ...
