Virtual reality is a computer-generated three-dimensional environment where seemingly real graphics are used to simulate an imaginary world. It is generally accessed by using a special VR helmet or spectacles which enable you to access this imaginary world. Virtual reality uses the concept of split-screen to project to different images to our eyes in a selected angle which makes our brain believe that we are viewing a three-dimensional image. This tricks the brain into thinking that the human is standing in a three-dimensional environment where they can move around. Over the years, virtual reality has been included in a lot of traditional fields to challenge the endless possibilities in those fields. It has been used in medical sciences to train doctors, the aerospace industry to train the pilots and astronauts, the architecture industry to obtain maximum efficiency in designing the structures, and many more fields. VR gaming is also becoming a huge market where people can interact with the game components to get a realistic experience of being in a game. VR is also being used by counselors and psychiatrists around the world to treat people with mental health problems. In this chapter, the authors use the concept of virtual reality in the live music industry to simulate realistic music concerts by designing and developing a platform to host virtual concerts using virtual reality.

Neurofeedback (NF) is a Brain-Computer Interface (BCI) application, in which the brain activity is fed back to the user in real-time enabling voluntary brain control. In this context, the significance of the feedback design is mainly unexplored. Highly immersive feedback scenarios using virtual reality (VR) technique are available. However, their effects on subjective user experience as well as on objective outcome measures remain open. In the present article, we discuss the general pros and cons of using VR as feedback modality in BCI applications. Furthermore, we report on the results of an empirical study, in which the effects of traditional two-dimensional and three-dimensional VR based feedback scenarios on NF training performance and user experience in healthy older individuals and neurologic patients were compared. In conclusion, we suggest indications and contraindications of immersive VR feedback designs in BCI applications. Our results show that findings in healthy individuals are not always transferable to patient populations having an impact on serious game and feedback design.

Boundary element (BE) analysis is well known as a tool for assessing the stiffness and strength of engineering components, but, along with finite element (FE) techniques, it is also finding new applications as a means of simulating the behaviour of deformable objects within virtual reality simulations since it exploits precisely the same kind of surface-only definition used for visual rendering of three-dimensional solid objects. This paper briefly reviews existing applications of BE and FE within virtual reality, and describes recent work on the BE-based simulation of aspects of surgical operations on the brain, making use of commercial hand-held force-feedback interfaces (haptic devices) to measure the positions of the virtual surgical tools and provide tactile feedback to the user. The paper presents an overview of the project then concentrates on recent developments, including the incorporation of simulated tumours in the virtual brain.

BACKGROUND Immersive virtual reality (VR) games are increasingly becoming part of everyday life. Several studies support immersive VR technology as a treatment method for mental health problems. There is however minimal research into the feasibility, prevalence, and quality of commercially available VR games on commercial platforms as tools for treatment or add on to treatment of mental health problems. OBJECTIVE The aim of this study was to explore the prevalence, feasibility and quality of commercially available games related to psychotherapy on a commercially available platform. METHODS We performed a search for keywords related to diagnosis and treatment strategies of mental health problems. The search was performed during March 27th on STEAM (VR content and gaming platform). A usability scale was used as a tool to look at the interaction and usability of the games, the VR-UI-UX-8. The tool contains 8 statements about usability scored 0-10, 0 indicating “Not at all” and 10 indicating “very much so”. The score ranges from 0-80 with a higher score indicating worse usability. RESULTS In total, 516 hits were found, 371 unique games. After the games were reviewed, 83 games passed the inclusion criteria, were purchased and played. Majority of the games which were excluded were either not connected to mental health, contained violence, adult content or were in other ways irrelevant or inappropriate. The mean score for the games on the VR-UI-UX-8 was 16.5 (standard deviation 15.8) with a range from 0-68. Most relevant and feasible games were found in the search words meditation, mindfulness, and LSD. CONCLUSIONS Commercial platforms hold great potential for VR games with psychotherapeutic components. The platforms are only at the beginning of the development towards serious games, e-learning and psychotherapeutic treatments. Currently the quality and usability for clinical and at home applicability are scarce, but hold great potential.

Abstract Aims Increased complexity in cardiac surgery over the last decades necessitates more precise preoperative planning to minimize operating time, to limit the risk of complications during surgery and to aim for the best possible patient outcome. Novel, more realistic, and more immersive techniques, such as three-dimensional (3D) virtual reality (VR) could potentially contribute to the preoperative planning phase. This study shows our initial experience on the implementation of immersive VR technology as a complementary research-based imaging tool for preoperative planning in cardiothoracic surgery. In addition, essentials to set up and implement a VR platform are described. Methods Six patients who underwent cardiac surgery at the Erasmus Medical Center, Rotterdam, The Netherlands, between March 2020 and August 2020, were included, based on request by the surgeon and availability of computed tomography images. After 3D VR rendering and 3D segmentation of specific structures, the reconstruction was analysed via a head mount display. All participating surgeons (n = 5) filled out a questionnaire to evaluate the use of VR as preoperative planning tool for surgery. Conclusion Our study demonstrates that immersive 3D VR visualization of anatomy might be beneficial as a supplementary preoperative planning tool for cardiothoracic surgery, and further research on this topic may be considered to implement this innovative tool in daily clinical practice. Lay summary Over the past decades, surgery on the heart and vessels is becoming more and more complex, necessitating more precise and accurate preoperative planning. Nowadays, operative planning is feasible on flat, two-dimensional computer screens, however, requiring a lot of spatial and three-dimensional (3D) thinking of the surgeon. Since immersive 3D virtual reality (VR) is an upcoming imaging technique with promising results in other fields of surgery, we aimed in this study to explore the additional value of this technique in heart surgery. Our surgeons planned six different heart operations by visualizing computed tomography scans with a dedicated VR headset, enabling them to visualize the patient’s anatomy in an immersive and 3D environment. The outcomes of this preliminary study are positive, with a much more reality-like simulation for the surgeon. In such, VR could potentially be beneficial as a preoperative planning tool for complex heart surgery.

AbstractThe selection and manipulation of objects in Virtual Reality face application developers with a substantial challenge as they need to ensure a seamless interaction in three-dimensional space. Assessing the advantages and disadvantages of selection and manipulation techniques in specific scenarios and regarding usability and user experience is a mandatory task to find suitable forms of interaction. In this article, we take a look at the most common issues arising in the interaction with objects in VR. We present a taxonomy allowing the classification of techniques regarding multiple dimensions. The issues are then associated with these dimensions. Furthermore, we analyze the results of a study comparing multiple selection techniques and present a tool allowing developers of VR applications to search for appropriate selection and manipulation techniques and to get scenario dependent suggestions based on the data of the executed study.
