“…CAVE iVR was favored in a few early studies because of higher reported levels of presence and stronger emotional responses in subjects, 96 , 97 whereas others found that participants rated HMD higher in terms of presence and showed better task performance 98 , 99 . Some studies suggested a minimal difference between the two systems regarding user attention, engagement, and comfort 95 , 100 , 101 . These inconsistencies might be partly attributed to the continuous evolution of iVR technologies, particularly the HMDs, which can dramatically impact user experiences.…”

. Immersive virtual reality (iVR) employs head-mounted displays or cave-like environments to create a sensory-rich virtual experience that simulates the physical presence of a user in a digital space. The technology holds immense promise in neuroscience research and therapy. In particular, virtual reality (VR) technologies facilitate the development of diverse tasks and scenarios closely mirroring real-life situations to stimulate the brain within a controlled and secure setting. It also offers a cost-effective solution in providing a similar sense of interaction to users when conventional stimulation methods are limited or unfeasible. Although combining iVR with traditional brain imaging techniques may be difficult due to signal interference or instrumental issues, recent work has proposed the use of functional near infrared spectroscopy (fNIRS) in conjunction with iVR for versatile brain stimulation paradigms and flexible examination of brain responses. We present a comprehensive review of current research studies employing an iVR-fNIRS setup, covering device types, stimulation approaches, data analysis methods, and major scientific findings. The literature demonstrates a high potential for iVR-fNIRS to explore various types of cognitive, behavioral, and motor functions in a fully immersive VR (iVR) environment. Such studies should set a foundation for adaptive iVR programs for both training (e.g., in novel environments) and clinical therapeutics (e.g., pain, motor and sensory disorders and other psychiatric conditions).

“…Many research activities have focused on virtual environments with cave like systems, where the user still sees his own body parts as well as the evaluated feedback devices (Giri et al, 2021). Nowadays, head mounted displays (HMDs) are increasingly represented, due to their expansion within the consumer market (Combe et al, 2021).This offers new possibilities for haptic feedback systems, because the user does not necessarily see any real surrounding. This article describes a tool replica which allows to simulate several hand-held tools.…”

Virtual reality offers new opportunities in production education and training. The simulation of haptic perception is, however, still an ongoing topic of research. This paper describes the development of a simple tool replica to simulate different hand-held tools out of the production. Different attributes like shape, weight and functionality of the replica are changed during a user study with 20 participants. The task within the virtual environment contains a simple screw driving scenario. The test runs compared on the resulting sense of presence, since it has already be shown that presence has an impact on the learning success. The results show significant effects especially in the subscale of experienced realism. The greatest effects are measured with all attributes integrated. However, an additional integration of a single attribute like realistic weight or functionality does not necessary lead to a significant increasing sense of presence.

“…Recently, with the advent of HMD (head-mounted display), VR began to be used in large numbers in all walks of life for professional use and in every household for personal use [1]. Many researches are interested in the difference in terms of visual perception in the two types of devices [2]. Another reason is the diversity and low cost of 3D application development platforms such as Unity3D, Unreal Engine, etc.…”

Virtual reality have advanced rapidly and are spreading in much of the world for huge numbers of application domains. However the cybersickness appears for many VR users and it is still a significant issue preventing them to feel free to use VR technology. In most of VR experience, the immersive display system can provoking much more self-motion perceived by eyes than the one given by vestibular systems. Through the sensory conflict theory, the mismatch in visual and vestibular sense causes sickness. In this paper a general framework for applying geometric simplification on the virtual scene is proposed with the aim of lowering the visually induced selfmotion that can be quantified by optic flow analyzed on the rendered images. The synthetized image that includes original scene at central part and simplified scene at peripheral part, are rendered to VR users. The analyzed optic flow on the synthetized images is much less than the one given by the original images.
