“…However, users felt that the TPD interface supporting passive haptic feedback could significantly improve the remote experts' user experience in VR. Webb et al [21] report on a study which designed and developed a multi-fingered haptic interface in conjunction with a threedimensional virtual model of a section of the cell membrane in order to enable students to work collaboratively to learn cell biology. Furthermore, the study investigated whether the addition of haptic feedback to the 3D VR simulation affected learning of key concepts in nanoscale cell biology for students aged 12 to 13.…”

Virtual Reality (VR) is gaining attention in various domains such as entertainment, industry, mental healthcare and VR training. Although most of these use-cases are still limited to single-user tasks, a lot of applications are heavily depending on multi-user collaboration. Existing multi-user VR systems are most often created in a classic server-client architecture, however, which induces unpredictable network behaviour which can affect the end-user's Qualityof-Experience (QoE) and performance. In addition, the interaction methods in these systems are often constrained to either traditional VR controllers or very use-case specific interaction methods, such that general purpose haptic gloves form a somewhat under-explored part of literature. Therefore, we (i) present a networked, distributed multi-user VR system with synchronization of environments over a low-bandwidth networked connection. In addition, we (ii) enhance the experience by adding haptic gloves to the system, which we compare to the traditional VR controllers in a subjective experiment. As a proof-of-concept, a use case is implemented in which two users have to prepare and bake a virtual pizza. The results show that high framerates (> 90 Frames Per Second (FPS)) can be obtained while keeping network throughput to a minimum (< 1 Mbps). The accompanying user study shows that haptic gloves are preferred when immersiveness is the main emphasis of the virtual environment, while controllers are more suited when performance is in the center of attention. In objective terms, the applicability of haptic feedback is highly dependent on the task at hand.

“…It saves time and cost of buying or building the equipment. Webb et al [17] simulated the nanoscale cell in 3D VR that helps biology students to understand the concepts in more depth and visualize it better as compared to 2D diagrams that are used traditionally. According to Edwards et al [18] haptic VR is very useful in the field of organic chemistry, because of its immersive learning ability.…”

In the past two decades, there has been a lot of work on computer vision technology that incorporates many tasks which implement basic filtering to image classification. The major research areas of this field include object detection and object recognition. Moreover, wireless communication technologies are presently adopted and they have impacted the way of education that has been changed. There are different phases of changes in the traditional system. Perception of three-dimensional (3D) from two-dimensional (2D) image is one of the demanding tasks. Because human can easily perceive but making 3D using software will take time manually. Firstly, the blackboard has been replaced by projectors and other digital screens so such that people can understand the concept better through visualization. Secondly, the computer labs in schools are now more common than ever. Thirdly, online classes have become a reality. However, transferring to online education or e-learning is not without challenges. Therefore, we propose a method for improving the efficiency of e-learning. Our proposed system consists of twoand-a-half dimensional (2.5D) features extraction using machine learning and image processing. Then, these features are utilized to generate 3D mesh using ellipsoidal deformation method. After that, 3D bounding box estimation is applied. Our results show that there is a need to move to 3D virtual reality (VR) with haptic sensors in the field of e-learning for a better understanding of real-world objects. Thus, people will have more information as compared to the traditional or simple online education tools. We compare our result with the ShapeNet dataset to check the accuracy of our proposed method. Our proposed system achieved an accuracy of 90.77% on plane class, 85.72% on chair class, and car class have 72.14%. Mean accuracy of our method is 70.89%.

“…This can be measured by means of the duration of the vibration, its frequency, and its amplitude [57]. A number of research studies conducted recently addressed the effect of haptic feedback in the form of vibration in the user's experience of the VRE [33,34,58,59]. The second decision is the form, type, and orientation of the sound originating from the objects and towards the user.…”

The application of Virtual Reality Environments (VRE) has been gaining momentum as a relatively new tool to assist with mitigating various difficulties including abstractness of concepts, lack of user engagement, perception of disconnection from other users. A VRE may offer both synchronous and asynchronous experiences, in addition to an immersive environment which promotes users’ engagement. Past research has shown that, in general, VRE do improve the experiences they try to enhance in many aspects of human activity. Terms like immersiveness and 3D representation of real life objects and environments are, as it appears, the two most obvious positive effects of Virtual Reality (VR) applications. However, despite these benefits it does not come without challenges. The main three concepts/challenges are the spatial design, the collaboration interaction between its members and the VRE, and the audio and video fidelity. Each of the three includes a number of other components that should be addressed for the total experience to be fine-tuned. These include mutual embodiment and shared perspectives, teleportation, gestural interaction, symmetric and asymmetric collaboration, physical and virtual co-location, inventory, and time and spatial synchronization. This paper comprises a survey of the literature, that identifies and explains the features introduced and the challenges involved with the VREs, and furthermore provides various interesting future research directions.
