Opportunities of Virtual Reality in the Therapy of Children and Adolescents

ZusammenfassungVirtuelle Realitäten (VR) werden seit Jahrzehnten erfolgreich in der Therapie von Angststörungen eingesetzt. Mit dem Aufkommen leistbarer Hardware (VR-Brillen) und der Zunahme kommerzieller Anbieter für entsprechende Softwareprogramme gewinnt die VR-Therapie auch abseits der klassischen Anwendungsbereiche an Bedeutung. Neben Erwachsenen rücken auch zusehends Kinder und Jugendliche in den Fokus. Dieser Artikel setzt sich daher zum Ziel, einen kursorischen Einblick in die Chancen von VR in der Pädiatrie wie auch Kinder- und Jugendpsychiatrie zu bieten. Die vorgestellten Anwendungsgebiete reichen von der Konfrontationstherapie mit VR, dem Einsatz bei Essstörungen und VR-basierten Trainings für Aufmerksamkeitsdefizit‑/Hyperaktivitätsstörung (ADHS) oder Autismus-Spektrum-Störungen (ASS) bis hin zu VR-basierten Biofeedbacksystemen und VR-Interventionen bei akuten Schmerzzuständen.

Şehir Planlaması İçin Sanal Gerçeklik

City planning as all kind of planning is about something unreal requiring much imagination capabilities by those involved in this process. Therefore, the traditional means to show the results of planning consisting mainly of lengthy reports and 2D maps are insufficient. Although research in the field of GIS based planning has dealt with a big number of visualization tools including glyph maps, heat map and traditional 2D graphics, research on the opportunities of Virtual Reality (VR) for simulating potential future states of our cities is missing. Such simulations would include exhibit the results of “what-if” scenarios to stakeholders like decision-makers and the general public.The purpose of this research was to develop a largely automated workflow from a 2D map of a city block to a 3D model and finally to a VR environment that can be used without expert knowledge. This will bring urban planning to a new level by visualization of big development projects on the spot. The development of this workflow has been explained in detail. Deficiencies in the current approach are discussed and directions for future research are given.

Cellular-Connected Wireless Virtual Reality: Requirements, Challenges, and Solutions

Cellular-connected wireless connectivity provides new opportunities for virtual reality(VR) to offer seamless user experience from anywhere at anytime. To realize this vision, the quality-of-service (QoS) for wireless VR needs to be carefully defined to reflect human perception requirements. In this paper, we first identify the primary drivers of VR systems, in terms of applications and use cases. We then map the human perception requirements to corresponding QoS requirements for four phases of VR technology development. To shed light on how to provide short/long-range mobility for VR services, we further list four main use cases for cellular-connected wireless VR and identify their unique research challenges along with their corresponding enabling technologies and solutions in 5G systems and beyond. Last but not least, we present a case study to demonstrate the effectiveness of our proposed solution and the unique QoS performance requirements of VR transmission compared with that of traditional video service in cellular networks.

A multiparametric magnetic resonance imaging-based virtual reality surgical navigation tool for robotic-assisted radical prostatectomy.

Increased computational power and improved visualization hardware have generated more opportunities for virtual reality (VR) applications in healthcare. In this study, we test the feasibility of a VR-assisted surgical navigation system for robotic-assisted radical prostatectomy. The prostate, all magnetic resonance imaging (MRI) visible tumors, and important anatomic structures like the neurovascular bundles, seminal vesicles, bladder, and rectum were contoured on a multiparametric MRI using an in-house segmentation software. Three-dimensional (3-D) VR models were rendered and evaluated in a side room of the operating room. While interacting with the VR platform, a real-time stereo video capture of the in situ prostate was obtained to render a second 3-D model. The MRI-based model was then overlaid on the real-time model by using an automated alignment algorithm. Ten patients were included in this study. All MRI-based VR models were examined by surgeons immediately prior to surgery and at important steps where visualization of the tumors and their proximity to surrounding anatomic structures were critical. This was mainly during the preparation of the prostatic pedicles, neurovascular plexus, the apex, and bladder neck. All participants found the system useful, especially for tumors with locally aggressive growth patterns. For small and centrally located tumors, the system was not considered beneficial due to lack of integration into the robotic console. A fully integrated system with real-time overlays within the robotic stereo viewer was found to be the ideal scenario. We deployed a preliminary VR-assisted surgical navigation tool for robotic-assisted radical prostatectomies.

The opportunities of virtual reality in the rehabilitation of children with attention deficit hyperactivity disorder: a literature review.

Attention deficit hyperactivity disorder (ADHD) is one of the most common psychiatric disorders in childhood. This disorder, in addition to its main symptoms, creates significant difficulties in education, social performance, and personal relationships. Given the importance of rehabilitation for these patients to combat the above issues, the use of virtual reality (VR) technology is helpful. The aim of this study was to highlight the opportunities for VR in the rehabilitation of children with ADHD. This narrative review was conducted by searching for articles in scientific databases and e-Journals, using keywords including VR, children, and ADHD. Various studies have shown that VR capabilities in the rehabilitation of children with ADHD include providing flexibility in accordance with the patients' requirements; removing distractions and creating an effective and safe environment away from real-life dangers; saving time and money; increasing patients' incentives based on their interests; providing suitable tools to perform different behavioral tests and increase ecological validity; facilitating better understanding of individuals' cognitive deficits and improving them; helping therapists with accurate diagnosis, assessment, and rehabilitation; and improving working memory, executive function, and cognitive processes such as attention in these children. Rehabilitation of children with ADHD is based on behavior and physical patterns and is thus suitable for VR interventions. This technology, by simulating and providing a virtual environment for diagnosis, training, monitoring, assessment and treatment, is effective in providing optimal rehabilitation of children with ADHD.
