Abstract: A wearable device and a method for performing a registration process in the wearable device are provided. The wearable device includes a light source, a light sensor and a microcontroller that performs the method. In the method, the light source is activated to emit a detection light and the light sensor senses a reflected light. A light intensity of the reflected light is calculated. A registration value is produced based on the light intensity. Specifically, the detection light with a specific frequency to be registered in the registration value is used as a reference to detect whether the wearable device is properly worn by a person. For example, since the wearable device can be worn on the person's wrist, the registration value is used to detect whether the wearable device is away from the wrist.

The light source is disposed by the optical detecting component, and the packaging structure provides the waterproofing function to the optical detecting component and the light source. The packaging structure includes a main body, a light emitting unit, alight incoming unit and a waterproofing component. The main body covers the optical detecting component and the light source. The light emitting unit and the light incoming unit are disposed on the main body and respectively face the light source and the optical detecting component. The waterproofing component is filled into a gap formed between the main body and the housing, to prevent moisture from leaking into the gap to rust terminals of the optical detecting component and the light source.
