Despite virtual reality (VR) being initially marketed toward gaming, there are many potential and existing VR applications in various sectors and fields, including education, training, simulations, and even in exercise and healthcare. Unfortunately, there is still a lack of general understanding of the strengths and limitations of VR as a technology in various application domains. Therefore, the aim of this literature review is to contribute to the library of literature concerning VR technology, its applications in everyday use, and some of its existing drawbacks. Key VR applications were discussed in terms of how they are currently utilized or can be utilized in the future, spanning fields such as medicine, engineering, education, and entertainment. The main benefits of VR are expressed through the text, followed by a discussion of some of the main limitations of current VR technologies and how they can be mitigated or improved. Overall, this literature review shows how virtual reality technology has the potential to be a greatly beneficial tool in a multitude of applications and a wide variety of fields. VR as a technology is still in its early stages, but more people are becoming interested in it and are optimistic about seeing what kind of changes VR can make in their everyday lives. With how rapidly modern society has adapted to personal computers and smartphones, VR has the opportunity to become the next big technological turning point that will eventually become commonplace in most households.

Although Virtual Reality (VR) was first mentioned in the 60s, the research interest into the technology and its application are still gaining much attention globally. VR technology had evolved and had found niche application in many fields including entertainment, tourism, healthcare, manufacturing, education and more. A notable characteristic of the VR technology is that it seeks to immerse the user into the intended environment and narrative, allowing high user interaction and involvement. These qualities are very beneficial for engineering education. In the past, cost, hardware capabilities and availability, connectivity and other issues had hindered VR wider adoption and application. However, it is changing with the advent of more devices, the involvement of more consumer electronic players and the growth of digitization. This paper seeks to report on the research on virtual reality in engineering education over the past 26 years. The study conducts a bibliometric analysis to reflect the trend of VR in engineering education settings, thus identifying the possible emerging trends. An extensive literature search was conducted using the Scopus database and was analyzed using Vosviewer and Excel. There is an increasing trend of VR research related to the engineering education settings with an evident increase in the scope, the coverage and the citations figures. There is tremendous growth in the number of publications and citations in the recent past four years of the study. The most active author in the field is Sampaio, and the top universities where the publications are affiliated with are Purdue University and Clemson University. The majority of the publications were also found to be affiliated with the "ASEE Annual Conference and Exposition Conference Proceedings". The United States had the honor of being the country with the majority of publications from this study. There is a continuous shift of research interest observed through the publications keywords, and this provides an indication of the dynamic progression of research direction among researcher in the field of study. The findings of this study provide a good overview of the trend in research related to VR in engineering education and can serve as a guide to academics seeking to research or adapt the usage of VR in engineering settings.

This document presents a systematic review of Multimodal Human–Computer Interaction. It shows how different types of interaction technologies (virtual reality (VR) and augmented reality, force and vibration feedback devices (haptics), and tracking) are used in different domains (concepts, medicine, physics, human factors/user experience design, transportation, cultural heritage, and industry). A systematic literature search was conducted identifying 406 articles initially. From these articles, we selected 112 research works that we consider most relevant for the content of this article. The articles were analyzed in-depth from the viewpoint of temporal patterns, frequency of usage in types of technology in different domains, and cluster analysis. The analysis allowed us to answer relevant questions in searching for the next steps in work related to multimodal HCI. We looked at the typical technology type, how the technology type and frequency have changed in time over each domain, and how papers are grouped across metrics given their similarities. This analysis determined that VR and haptics are the most widely used in all domains. While VR is the most used, haptic interaction is presented in an increasing number of applications, suggesting future work on applications that configure VR and haptic together.

Modern society is increasingly permeated by realities parallel to the real one. The so-called virtual reality is now part of both current habits and many activities carried out during the day. Virtual reality (VR) is, in turn, related to the concept of augmented reality (AR). It represents a technology still in solid expansion but which was created and imagined several decades ago. This paper presents an overview of augmented reality, starting from its conception, passing through its main applications, and providing essential information. Part of the article will be devoted to hardware and software components used in AR systems. The last part of the paper highlights the limitations related to the design of these systems, the shortcomings in this area, and the possible future fields of application of this extraordinary technological innovation.

Virtual Reality (VR) sickness is common with symptoms such as headaches, nausea, and disorientation, and is a major barrier to using VR. We propose WalkingVibe, which applies unobtrusive vibrotactile feedback for VR walking experiences, and also reduces VR sickness and discomfort while improving realism. Feedback is delivered through two small vibration motors behind the ears at a frequency that strikes a balance in inducing vestibular response while minimizing annoyance. We conducted a 240-person study to explore how visual, audio, and various tactile feedback designs affect the locomotion experience of users walking passively in VR while seated statically in reality. Results showed timing and location for tactile feedback have significant effects on VR sickness and realism. With WalkingVibe, 2-sided step-synchronized design significantly reduces VR sickness and discomfort while significantly improving realism. Furthermore, its unobtrusiveness and ease of integration make WalkingVibe a practical approach for improving VR experiences with new and existing VR headsets.
