1. An apparatus for estimating bio-information, the apparatus comprising:
a pulse wave sensor configured to measure a pulse wave signal from an object;
a sensor position sensor configured to obtain sensor position information of the pulse wave sensor with respect to the object, based on the object being in contact with the pulse wave sensor;
a blood vessel position sensor configured to obtain blood vessel position information of the object;
a processor configured to estimate the bio-information based on the blood vessel position information of the object, the sensor position information, and the pulse wave signal; 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.
