Claim 11:
12. A method of estimating bio-information, the method comprising:
obtaining a bio-signal from an object;
obtaining a second-order differential signal of the bio-signal;
determining whether a first local minimum point of the second-order differential signal is stable or unstable;
based on determining that the first local minimum point of the second-order differential signal is stable, extracting a progressive wave component using the first local minimum point of the second-order differential signal,
based on determining that the first local minimum point of the second-order differential signal is unstable, extracting the progressive wave component from the bio-signal using a maximum amplitude point in a systolic portion of the bio-signal;
determining the estimated bio-information based on the extracted progressive wave component, the estimated bio-information representing an actual health condition of a user having the object; and
directing an output interface to provide the estimated bio-information to the user so as to monitor the actual health condition.
