1. A wearable electronic device for measuring of physiological information of a user, comprising:
a main body configured to be at least partially worn on an index finger of a hand of the user;
a functional component coupled to the main body, comprising:
a first light emitter coupled to the main body for emitting a first light to the index finger of the user;
a second light emitter coupled to the main body for emitting a second light to the index finger;
a light detector coupled to the main body for detecting reflected first and second light from the index finger; and
a matching unit coupled to the main body and comprising an extending unit extending from the main body in an opposing direction to the functional component,
wherein the first and second light emitters are arranged substantially in a linear relationship with the light detector in a longitudinal direction of the index finger during measuring of physiological information of the user, and the extending unit is configured to be coupled with an adjacent finger to align the device and place the functional component toward the thumb of the hand when worn.
