Classification: CPC A | IPC A

Claim 18:
19. An apparatus for estimating bio-information of a user, the apparatus comprising:
a pulse wave sensor configured to measure a pulse wave signal from an object of the user;
a sensor position sensor configured to obtain sensor position information of the pulse wave sensor with respect to the object;
a blood vessel position sensor configured to obtain the blood vessel position information of the object;
a processor configured to:
obtain sensor position information that identifies a position of the pulse wave sensor with respect to the object of the user;
obtain blood vessel position information that identifies a position of a blood vessel of the object of the user; and

estimate the bio-information of the user based on the pulse wave signal, the sensor position information, and the blood vessel position information, and
a display, wherein
the processor is further configured to control the display to guide a user to place the pulse wave sensor at a blood vessel position of the object based on the blood vessel position information of the object and the sensor position information.
