Claim 0:
1. A wearable electronic device for measuring physiological information from a user, comprising:
a main body comprising a first loop configured to receive an index finger of the user;
a matching unit extending from the main body to a lateral side and comprising a first extending unit and a second extending unit;
an optical sensor including:
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 of the user;
and a light detector for receiving light emitted by the first and second light emitters to measure the physiological information from the user, wherein the light detector and the first light emitter are arranged along a first longitudinal direction, wherein longitudinal direction is a direction that extends substantially from finger root to fingertip;

wherein the first and second extending units are configured to couple with an adjacent finger to the index finger to reduce rotation of the electronic device about a longitudinal direction of the index finger when worn on the index finger of the user and the first direction is substantially parallel to the longitudinal direction.
