碩士 === 中央警察大學 === 刑事警察研究所 === 107 === Crime scene investigation is one of the most important steps for the investigation and trail process. The crime scene can provide lots of clues such as physical evidence, modus operandi, etc., that helps investigators to link to the potential suspect. Crime scene investigators’ ability to collect evidence and assess crime scene could assist detectives to solve crime efficiently and correctly. There are few studies exploring investigative thinking and decision making during crime scene investigation. The aim of this study is to compare investigative thinking of experts and novices through eye tracking data and interview. In this study we use omnidirectional camera to scan a stimulated criminal scene in order to construct the virtual reality. 48 participants were recruited from Central Police University and other forensic departments who were categorized as novices and experts groups. The expert and novice examiners wore the virtual reality glasses combined with the eye trackers, and compared the investigation strategies in the crime scenes from eye tracking data, hotspot gaze. The participants were interviewed for requiring their investigative thinking logic and VR experince during the stimulated crime scène investigation. The result shows the experts searched evidence more efficiently than the novices because of their prior experiences, while derived the crime scenes more conservatively. Finally, we suggest that VR could be a useful tool for crime scene investication training.
