Abstract

A method of authenticating a user of a head mounted display (HMD) device includes measuring a characteristic value of a head shape of the user who wears the HMD device by using at least one sensor included in the HMD device, and authenticating a use authority of the user who wears the HMD device based on the measured characteristic value and a characteristic value registered in advance for a head shape of a user who has an authority to use the HMD device.

Background

To meet the lightweight and miniaturization trends of digital devices, various wearable devices are under development. A head mounted display (HMD) device, which is a kind of a wearable device, is a digital device worn by a user on the head to receive multimedia content or experience virtual reality (VR) or augmented reality (AR). The HMD device may have various forms to be worn on the head such as glasses or a part of a helmet.

When the HMD device is used, authenticating a use authority of a user who uses the HMD device is an important issue for protection of personal information, security, content providing, etc. A method of authenticating an HMD device may be implemented in various ways. For example, a method of authenticating the HMD device may be implemented via an iris authentication algorithm performed by an iris recognition scanner to recognize an iris of a user who wears the HMD device or an authentication algorithm for recognition of a user’s face.

Summary

Provided are methods of authenticating a use authority of a user who wears a head mounted display (HMD) device and an HMD device performing the method.

Provided are methods of identifying a specific user from among a plurality of users who use an HMD device and an HMD device performing the method.

An embodiment of present disclosure provides a convenient, accurate, and reliable biometric authentication method by obtaining a curvature curve for a head shape of a user who wears the HMD device via the plurality of sensors included in the HMD device, and authenticating a use authority of the user. Also, the authentication method according to the embodiment does not require an additional iris recognition sensor, face scanner, etc., so that additional costs may be saved and thus the authentication method is advantageous in an aspect of costs.
