Claim 11:
12. A method of measuring physiological information from a user with a wearable electronic device, the method comprising:
coupling the electronic device with an index finger of the user through a first loop of the device,
coupling an adjacent finger to the index finger with a matching unit of the device, the matching unit extending from the main body to a lateral side and comprising a first extending unit and a second extending unit,
emitting a first light from a first emitter and a second light from a second emitter to the index finger, and receiving a reflected light with a light detector to measure the physiological information from the user,

wherein the light detector and the first light emitter are aligned along a first longitudinal direction wherein longitudinal direction is a direction that extends substantially from finger root to fingertip, and the first and second extending units are coupled with the adjacent finger to reduce rotation of the electronic device about the first direction wherein the first direction is substantially the longitudinal direction of the index finger.
