“…Usually, 3D representations of crime scenes are inspected in ordinary monitors, however, the presentation in a virtual reality environment enhances the experience and permits immersive interactions. VR itself has been shown as an interesting modality able to engage non-experts for crime scene inspections [17,18]. Under these considerations, a line of works utilised VR in their pipelines.…”

A Study of 3D Digitisation Modalities for Crime Scene Investigation

A valuable aspect during crime scene investigation is the digital documentation of the scene. Traditional means of documentation include photography and in situ measurements from experts for further analysis. Although 3D reconstruction of pertinent scenes has already been explored as a complementary tool in investigation pipelines, such technology is considered unfamiliar and not yet widely adopted. This is explained by the expensive and specialised digitisation equipment that is available so far. However, the emergence of high-precision but low-cost devices capable of scanning scenes or objects in 3D has been proven as a reliable alternative to their counterparts. This paper summarises and analyses the state-of-the-art technologies in scene documentation using 3D digitisation and assesses the usefulness in typical police-related situations and the forensics domain in general. We present the methodology for acquiring data for 3D reconstruction of various types of scenes. Emphasis is placed on the applicability of each technique in a wide range of situations, ranging in type and size. The application of each reconstruction method is considered in this context and compared with respect to additional constraints, such as time availability and simplicity of operation of the corresponding scanning modality. To further support our findings, we release a multi-modal dataset obtained from a hypothetical indoor crime scene to the public.

“…However, the task of obtaining realistic results from the 3D scanning of a physical environment, particularly one that contains forensic elements such as blood droplets or wall marks, presents a significant challenge (Noghabaei et al 2019). Despite numerous endeavours to reconstruct interior crime scenes, the most formidable obstacle was capturing blind spots within confined spaces, leading to an incomplete representation of the scene (Wang et al 2019;Jani and Johnson 2022;Mach et al 2019). In light of these difficulties, a comprehensive review of techniques was conducted by exploring similar cases in the field of cultural heritage and through consultation with experts.…”

Police investigation in real-life crime scenes is an essential aspect of forensic science education. However, the practicality of bringing young investigators to actual crime scenes is often hindered by the costs and challenges involved. In order to overcome these obstacles, new technologies such as mixed reality (MR) are being explored as potential solutions. MR technology offers an interactive and cost-effective way to simulate real-life crime scenes, providing a valuable training experience for young investigators. This paper presents a novel design of a MR system using Microsoft HoloLens 2.0, which is tailored to work in a spatial 3D scanned and reconstructed crime scene using FARO point cloud 3D scanner X130 blended with photogrammetry techniques. The system was developed through the lens of Experiential Learning Theory and designed using a participatory approach, providing a cost-effective solution to help trained Kuwaiti police officers enhance their investigative skills. In order to evaluate the system’s user experience and user interaction, the Questionnaire of User Interaction Satisfaction and User Experience Questionnaire were utilised. Forty-four young police officers evaluated the system. Police students showed positive levels of satisfaction with user interaction and overall user experience with minimal negative feedback. Female students showed higher satisfaction with the overall impression compared to male students. Based on the positive feedback regarding the system expansion, the system will be taken into the commercialisation stage in the future to be provided as an essential tool for crime scene education and investigation practices.

“…One of these technologies is virtual reality technology, which is gradually building its place in the IRS. According to V. Mach [18], virtual reality can be defined as "an advanced user interface that includes a simulation of a real environment in real-time, where the user interacts through several sensory channels (sight, hearing, touch, smell, and taste)".…”

To successfully deal with emergent events or crises, it is necessary to have a fully planned integrated rescue system (IRS). The stages of the IRS are tested by exercises that aim to model rescue and clean-up operations as closely as possible. This article compares different software tools to support the creation and implementation of exercises of different stages of the IRS. The article aims to compare suitable software tools and evaluate their application in the individual phases of creating tactical exercises in the IRS and application to the implementation and evaluation phase. Methods of explanation, comparison, and modeling are used to achieve the goals. It was found that the investigated software programmes are all suitable for use in the organization of exercises. The results are shown in a comparison table and examples of individual model situations. The article presents possible implementation scenarios of software tools for creating and organizing exercises of stages of the IRS, which can make the preparation of both tactical and screening exercises more efficient.
