Suzuki-san presented a talk at EuroUSEC 2023, which is held in Copenhagen. We got excellent questions/comments from the audience. In this study, we introduce “PinchKey,” a novel VR authentication method leveraging the natural ‘pinch’ gesture. Here’s a snapshot:
Intuitive & User-Friendly: Replaces traditional methods like pattern locks or PINs, using the VR-familiar pinch gesture.
Technical Insight: Uses a supervised machine learning model to analyze the 3D trajectory of the pinch gesture for authentication.
Tested on Meta Quest 2: Our evaluation with 29 participants showed an impressive average AUC of 99.7% and a swift average authentication time of 1.65 seconds.
High Usability Score: Achieved a top-tier system usability scale (SUS) score of 86.25.
Real-World Ready: Demonstrated resilience against potential threats.
In essence, PinchKey offers a seamless, accurate, and rapid VR authentication experience. Watch out for its wider adoption in the VR realm!
