1. A method comprising:
- receiving an indication of an eye gesture from at least one proximity sensor in a head-mountable device (HMD) configured to generate sensor data indicative of light reflected from an eye area;
responsive to receiving the indication of the eye gesture, (i) vibrating a bone conduction transducer associated with the HMD near a bony portion of a head of a wearer of the HMD so as to transmit vibrations through the head of the wearer, and (ii) capturing biometric information indicative of a head vibration response pattern of the vibrations transmitted through the head of the wearer of the HMD, wherein the captured biometric information comprises one or more of vibration information from an accelerometer associated with the HMD and acoustic information from a microphone associated with the HMD; and
authenticating the wearer of the HMD based on a comparison of the head vibration response pattern indicated by the captured biometric information and a stored head vibration response profile.

Abstract
A head-mountable device configured to authenticate a wearer is disclosed. The head-mountable device can receive an indication of an eye gesture from at least one proximity sensor in the head-mountable device configured to generate sensor data indicative of light reflected from an eye area. The head-mountable device can capture biometric information indicative of one or more biometric identifiers of a wearer of the head-mountable device responsive to receiving the indication of the eye gesture. The head-mountable device can authenticate the wearer of the head-mountable device based on a comparison of the captured biometric information and a stored biometric profile.

5. A head-mountable device (HMD) comprising:
-
an eye gesture detection system including at least one light source configured to illuminate an eye area and at least one proximity sensor configured to generate sensor data indicative of light reflected from the eye area; a head vibration response pattern characterization system including a bone conduction transducer configured to vibrate near a bony portion of a head of a wearer of the HMD so as to transmit vibrations through the head of the wearer, and at least one sensor configured to generate data indicative of a head vibration response pattern of the vibrations transmitted through the head the wearer of the HMD, wherein the at least one sensor comprises one or more of an accelerometer associated with the HMD and configured to generate vibration data and a microphone associated with the HMD and configured to generate acoustic data; and a controller configured to;
(i) receive an indication of an eye gesture from the eye gesture detection system;
(ii) responsive to receiving the indication of the eye gesture, cause the head vibration response pattern characterization system to;
(a) vibrate the bone conduction transducer so as to transmit vibrations through the head of the wearer, and (b) capture biometric information indicative of the head vibration response pattern of the vibrations transmitted through the head of the wearer of the HMD; and
(iii) authenticate the wearer of the HMD based on a comparison of the head vibration response pattern indicated by the captured biometric information and a stored head vibration response profile. - View Dependent Claims (6, 7)
