1. A head mounted device (HMD) comprising:
- at least one camera configured to capture one or more partial region images of an iris;
an electrocardiogram (ECG) sensor configured to receive ECG signals; and
at least one processor configured to authenticate a user by acquiring at least one of the one or more partial region images, which are captured by the at least one camera, and the ECG signals, which are received through a plurality of electrodes,wherein the at least one processor is further configured to generate a normalized image to authenticate the user, by combining the one or more partial region images and by using a curvature of an inner contour line of the iris, which is included in the one or more partial region images.

Abstract
A head mounted device (HMD) includes an imaging unit configured to capture at least one image of a partial region of an iris, an electrocardiogram (ECG) sensor configured to receive an ECG signal, and a control unit configured to acquire at least one image of the partial region of the iris and ECG signals, and authenticate a user by using the acquired image(s) of the partial region of the iris and the ECG signals.

12. A head mounted device (HMD) comprising:
-
a plurality of electrodes configured to detect ECG signals disposed in the HMD; and at least one processor configured to; receive ECG signals through the plurality of electrodes, measure a signal-to-noise ratio (SNR) of the received ECG signals, compare the SNR of the received ECG signals to a threshold value, perform user authentication based on the received ECG signals when the SNR of the received ECG signals is greater than or equal to the threshold value, and perform the user authentication based on biometric information received from at least one biometric sensor when the SNR of the received ECG signals is less than the threshold value, wherein the at least one biometric sensor is different from an ECG sensor. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
