WEARABLE MOBILE TERMINAL
First Claim
1. A wearable terminal, comprising:
- a main body configured to contact a body part of a user;
a photo plethysmography comprising;
a transmitter located on one side of the main body and configured to output a signal; and
a receiver configured to detect a reflection signal that is reflection of the output signal;
a cover of the main body configured to cover the photo plethysmography, the cover comprising;
transparent units aligned with the transmitter and the receiver, the transparent units configured to pass the output signal and the reflection signal; and
a barrier unit positioned between the transparent units and configured to shield the output signal and the reflection signal; and
a controller configured to measure a heart rate based on the detected reflection signal.

Abstract
A wearable terminal can include a main body configured to be in contact with a body of a user using one side of the main body, a photo plethysmography including a transmitter combined with one side of the main body and outputs a output signal, and a receiver detecting a reflection signal corresponding to the output signal returned, a cover configured to cover the photo plethysmography and be combined with the main body and a controller configured to measure a heart rate based on a reflection signal measured by the photo plethysmography. The cover is combined with the main body and parts corresponding to the transmitter and the receiver of the photo plethysmography include transparent units through which the output signal and the reflection signal are passing and a barrier unit positioned between the transparent units and shielding the output signal and the reflection signal.

5. A wearable terminal, comprising:
-
a main body configured to contact a body part of a user; a photo plethysmography comprising; a transmitter located on one side of the main body and configured to output a signal, and a receiver configured to detect a reflection signal that is a reflection of the output signal from a blood cell in a blood vessel of the user; an acceleration sensor configured to detect movement of the main body; and a controller configured to; calculate reflection signal data based on a direction and a speed of the movement detected by the acceleration sensor by compensating the reflection signal; and calculate a heart rate based on a number of changes in the reflection signal data per reference time. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method for controlling a wearable terminal, the method comprising:
-
outputting a signal to a body part of a user; receiving a reflection signal that is a reflection of the output signal; detecting movement of a main body of the terminal; calculating reflection signal data based on the detected movement by compensating the received reflection signal; and calculating a heart rate based on a number of changes in the reflection signal data per reference time. - View Dependent Claims (19, 20)
