Projects
-
EEG decodability of facial expressions and their stereoscopic depth cues in immersive virtual realityProject details
Summary: The study integrates immersive virtual reality with EEG and eye tracking to examine face perception under controlled stereoscopic depth conditions. Using time-resolved multivariate decoding, EEG signals recorded in fully immersive VR reliably differentiated facial expressions. Stereoscopic depth cues elicit distinct, decodable neural signatures, while expression decoding remains robust across depth conditions, demonstrating the feasibility of multimodal decoding in 3D environments.

Project 3DIL: Revolutionising Eyewitness Identification — The 3D Interactive LineupProject details
Summary: The 3D Interactive Lineups (3DIL) project is transforming eyewitness identification through the use of 3D virtual reality (VR). Traditional 2D photo lineups can often lead to mistaken identifications, contributing to wrongful convictions. Our innovative approach uses advanced 3D modeling and neural rendering to create lifelike, interactive facial models, allowing witnesses to view suspects from multiple angles in VR. This project brings together an international team of experts in psychology, computer science, and law enforcement to set a new standard in criminal justice procedures.
Time: 2024–ongoing

Scientific Eye Tracking Data Quality in immersive Virtual Reality: A Comparison of Tethered and Mobile VR HeadsetsProject details
Summary: This study evaluates the eye-tracking performance of five state-of-the-art virtual reality (VR) headsets to assess their suitability for scientific research. Using data from 24 participants, the authors compare three mobile devices (Meta Quest Pro, PICO 4 Enterprise, HTC Vive Focus 3) and two tethered headsets (HTC Vive Pro Eye, Varjo Aero) on key performance metrics: spatial accuracy, precision, and temporal latency. Eye tracking was measured during fixation and saccade tasks performed with and without head movements, and latency was estimated relative to concurrently recorded electrooculography (EOG).
