On Authentication in Virtual Reality Environments for Rehabilitation and Psychotherapy Systems

Virtual and augmented reality techniques are increasingly used in medical recovery systems and for treating phobias or psychiatric disorders. Considering the specifics of the patients involved in these procedures, authentication in virtual environments raises challenges. This paper deals with some approaches for authentication based mainly on biometrics and coordinated 3D manipulation and pointing. The authentication solution based on ear identification has been integrated into a neuromotor recovery system. This approach was the most comfortable for patients, it was reliable and offered a very good response time.
