Augmented Virtuality Systems as a Tool for Improving Numeracy Decision-Making Among Children

Young children depend on the non-symbolic representation of numbers for their numeracy understanding and decision-making. The objective of the current research was to examine whether the use of an augmented virtuality (AV) system to represent numbers as physical objects, compared to representing them only visually on a computer screen, will improve children’s numeracy decision-making. The question was evaluated by comparing children’s decisions to buy more profitable versus non-profitable products, as well as their total profit, when the coins and the coin machine are real (AV system group) compared to their decisions when using a system in which the coins and the coin machine are virtual (virtual system group). Two between-participants groups of children aged 6–8 participated in this study, with 30 children in each group. The results demonstrated that in the AV system group, the children invested more proportionately in the profitable versus non-profitable products, while in the virtual system group, the opposite occurred. As a result of their better decision-making, the total profits of the AV system group were higher than those of the virtual system group. The current findings are an interesting addition to the existing literature on the contribution of virtual reality and augmented reality systems in improving mathematical learning.

The Contribution of Virtual Reality to Social and Emotional Learning in Pre-Service Teachers

This research focused on pre-service teachers’ experiences in a virtual reality (VR) teaching unit that was included in a special course, “Educating for the Future,” designed to enhance skills needed in the twenty-first century. The study examined how the trainees’ experiences of working with VR affected their social and emotional learning. The research population included 176 students in their second year of a four-year training course to become teachers in the K-12 educational system. The research questions were whether teaching approaches employing VR have an impact on student teachers’ social and emotional learning (SEL); and, if so, how collaboration in VR classroom activities and projects fosters learners’ SEL. The study’s main findings demonstrated that VR learning environments helped student teachers increase their social and emotional involvement in their learning and enabled them to become more innovative and creative as they harnessed the powers of VR. VR challenges learners with active teaching and learning and transforms student teachers into active participants who create and innovate.

Contribution of virtual reality in clinical practice in ophthalmology

PurposeFeasibility study of a device allowing recording, transmission and viewing by another operator of a stereoscopic clinical examination at the slit lamp.MethodsTwo medical cameras (CM900, Haag‐Streit, Bern, Switzerland) were mounted on a slit lamp (BQ900, Haag‐Streit, Bern, Switzerland) equipped with a beam splitter allowing to record stereoscopic videos. The video footage associated with the patient's clinical data were then remotely transmitted to another examiner located in another room via a secure server dedicated to telemedicine. The data was then visualized through augmented reality glasses type Oculus Rift DK2 (Oculus VR, California) for stereoscopic viewing of the recorded consultation.ResultsFive patients consulting for diseases of the anterior and posterior segments were examined remotely and the diagnosis was consistent with that of the first examiner in all cases.ConclusionsThe success of this experience of telemedicine and augmented reality offers significant opportunities in the fields of education and remote consultation.

Radiofrequency ablation of hepatic tumors: simulation, planning, and contribution of virtual reality and haptics

For radiofrequency ablation (RFA) of liver tumors, evaluation of vascular architecture, post-RFA necrosis prediction, and the choice of a suitable needle placement strategy using conventional radiological techniques remain difficult. In an attempt to enhance the safety of RFA, a 3D simulator, treatment planning, and training tool, that simulates the insertion of the needle, the necrosis of the treated area, and proposes an optimal needle placement, has been developed. The 3D scenes are automatically reconstructed from enhanced spiral CT scans. The simulator takes into account the cooling effect of local vessels greater than 3 mm in diameter, making necrosis shapes more realistic. Optimal needle positioning can be automatically generated by the software to produce complete destruction of the tumor, with maximum respect of the healthy liver and of all major structures to avoid. We also studied how the use of virtual reality and haptic devices are valuable to make simulation and training realistic and effective.

Prototyping Manufacturing Systems. Contribution of Virtual Reality, Agents and Petri Nets

The necessity of low-cost and rapid prototyping tools is often arisen in the field of manufacturing system design. This work showed that virtual reality, combined with multi-agent systems was a very efficient method to perform such a prototype. Virtual reality offered an easy to understand representation of the future system and a powerful reactivity from end-users. Because Agent paradigm enforced local point of view, modularity and re-usability could be achieved. Applied on the KorSo case study, this method led to a fully distributed architecture without any centralized controller. Agent-orientness was also a very structuring approach, specially because behaviors were modeled by Petri nets
