In this project, we are investigating the reasoning and factors behind the Privacy-Granting Decision (PGD) of the user in terms of mobile devices.

• Project 1 — Understanding the users' perception

• Project 2 — Understanding the context 

This project investigates how authentication methods can be designed and evaluated for enhanced usability within immersive virtual reality (VR) environments. Building on prior work with PINs and gestures, it explores broader interaction paradigms—such as spatial input and visual feedback—to support secure and user-friendly authentication in VR systems.

• Project 1 — Implicit Visual Cues for Seamless Authentication in Virtual Reality

This project investigates the use of subtle visual cues in VR enabling seamless and continuous user authentication without interrupting the immersive experience.
