Seamless Crime Scene Reconstruction in Mixed Reality for Investigation Training: A Design and Evaluation Study

Investigation training in the real crime scene is a critical component of forensic science education. However, bringing young investigators to real crime scenes is costly and faces significant challenges. Mixed Reality (MR) is one of the most evolving technologies that provide unlimited possibilities for practical activities in the education sector. This paper aims to propose and evaluate a novel design of an MR system using Microsoft HoloLens 2.0 and it is tailored to work in a spatial 3D scanned and reconstructed crime scene. The system was designed to be a costly-effective experience that helps young Kuwait police officers to enhance their investigation skills. The proposed system has been evaluated through system usability, user interaction and performance metrics quantitatively via 44 young police officers, and qualitatively using the Think-aloud protocols via a group of experts. Both groups showed positive levels of usability, user interaction and overall satisfaction with minimal negative feedback. Based on the positive feedback, the system will be taken into the commercialisation stage in the future. Despite the high cost of the MR device, it was stated by experts that the system is needed to be provided as an essential tool for crime scene education and investigation practices

Collaboration in virtual and augmented reality : a systematic overview

This paper offers a systematic overview of collaboration in virtual and augmented reality, including an assessment of advantages and challenges unique to collaborating in these mediums. In an attempt to highlight the current landscape of augmented and virtual reality collaboration (AR and VR, respectively), our selected research is biased towards more recent papers (within the last 5 years), but older work has also been included when particularly relevant. Our findings identify a number of potentially under-explored collaboration types, such as asynchronous collaboration and collaboration that combines AR and VR. We finally provide our key takeaways, including overall trends and opportunities for further research

A Novel Classification of Lung Cancer into Molecular Subtypes

The remarkably heterogeneous nature of lung cancer has become more apparent over the last decade. In general, advanced lung cancer is an aggressive malignancy with a poor prognosis. The discovery of multiple molecular mechanisms underlying the development, progression, and prognosis of lung cancer, however, has created new opportunities for targeted therapy and improved outcome. In this paper, we define “molecular subtypes” of lung cancer based on specific actionable genetic aberrations. Each subtype is associated with molecular tests that define the subtype and drugs that may potentially treat it. We hope this paper will be a useful guide to clinicians and researchers alike by assisting in therapy decision making and acting as a platform for further study. In this new era of cancer treatment, the ‘one-size-fits-all’ paradigm is being forcibly pushed aside—allowing for more effective, personalized oncologic care to emerge

Real scale augmented reality. a novel paradigm for archaeological heritage fruition

none4no3D contents have great potential in improving the communication and fruition of Cultural Heritage (CH). The visiting experience on an archaeological site or historical building can be improved by digital contents that help visitors to discover and learn how they once appeared. Augmented Reality (AR) is one of the technologies nowadays used for CH exploitation and it has the great quality of superimposing digital contents on elements of the reality. This paper shows a new interactive application on the archaeological site of Forum Sempronii: thanks to SLAM technology it allows the visitors to see several virtual reconstructions superimposed on the ruins walking around the site, so that they can see how anciently the roman city was. Great attention has been given to the creation of 3D contents: after the creation of high poly models they have been decimated and optimized in terms of number of polygons and textures in order to be fluently managed on mobile devices. The fruition of real scale contents on the real context increases immersive users’ experiences.restrictedDragoni, Aldo F.; Quattrini, Ramona*; Sernani, Paolo; Ruggeri, LudovicoDragoni, Aldo F.; Quattrini, Ramona; Sernani, Paolo; Ruggeri, Ludovic
