Identification parade in immersive virtual reality - A technical setup.

Area of Science:

• Forensic Science
• Virtual Reality Technology
• Human Identification

Background:

• Traditional suspect identification methods, like live lineups, present practical challenges including witness and suspect interaction and participant recruitment.
• Existing methods like paper-based identification have limitations, particularly regarding non-facial features such as body stature.
• Virtual Reality (VR) is emerging as a potential tool in forensic science, particularly for training and scenario visualization.

Purpose of the Study:

• To evaluate the technical feasibility of using Virtual Reality (VR) for conducting identification parades.
• To compare the effectiveness of VR-based identification with traditional paper-based methods.
• To explore VR's potential to address limitations of conventional identification procedures.

Main Methods:

• Fifteen subjects were 3D documented using the 'Photobox' multi-camera system.
• Participants viewed 3D models of individuals in a VR environment.
• Students were tasked with identifying a specific individual from a lecture within both VR and paper-based identification sets.

Main Results:

• Participants successfully identified the target individual in both the Virtual Reality (VR) and paper-based identification sets.
• The study demonstrated that VR technology is technically capable of supporting person identification.
• While successful, this preliminary study did not deeply analyze the similarity problem, which requires further investigation.

Conclusions:

• Virtual Reality (VR) presents a viable technological solution for suspect identification parades in forensic science.
• VR identification methods show promise in overcoming practical disadvantages associated with traditional lineups.
• Further research is needed to confirm the robustness of VR identification, particularly concerning the similarity of individuals presented.
