New biometrics Ear-Eye Pitch (E2P)

We propose a new Ear-Eye Pitch (E2P) biometric parameter. This parameter is conceptually different from the typically used anthropometric parameters since it is defined and measured in angular units, while traditional parameters are measured in linear units. We present an inventive measurement technique by using a commercially available, see-through head-mounted-display (HMD), such as Google Glass. We provide an extensive analysis of the accuracy of our measurement procedure as well as statistical study of the subjects group measuring their E2P. The result of this study allows differentiating people according to their E2P, with such differentiation being practically orthogonal to prior known biometrics. Complementary to direct biometrics application, E2P parameter justifies an additional step in see-through HMD calibration for various augmented reality applications resulting in improved overlay registration.
