Abstract
Augmented Reality and Virtual Reality (AR/VR) technologies are revolutionizing educational experiences, but their widespread adoption hinges on addressing critical security and usability challenges, particularly in the domain of user authentication. This research presents an investigation into the security landscape of AR/VR and explores a graphical authentication scheme called “Things” that enhances both security and usability in immersive learning environments. Through a systematic evaluation of popular AR/VR devices and applications, potential vulnerabilities and limitations were identified, such as high usage of pin/passwords which are susceptible to shoulder-surfing attacks, lack of multi-factor authentication, and unclear data-sharing practices. A review of existing knowledge-based authentication schemes revealed a scarcity of shoulder-surfing-resistant methods suitable for AR/VR. Subsequent technical evaluations and user studies validated the effectiveness, memorability, and user acceptance of the “Things” scheme, which employs familiar object images for authentication. The replication study conducted in AR and VR environments demonstrated the scheme’s superior performance on the Valve Index VR platform compared to the Microsoft HoloLens AR device. Interestingly, integrating the “Things” scheme into a VR classroom setting resulted in high authentication success rates, low perceived workload, and improved knowledge retention among participants. Our study aims to address the security and usability challenges of authentication in AR/VR, we contribute to the responsible development and adoption of immersive technologies in education, paving the way for secure and engaging learning experiences.
