Abstract:
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.
