“…Previous studies 3,5,30 regarding the interaction and user interface in immersive VR confirmed that the direct control of virtual environments and objects using hands improved presence. For more realistic representations of the hand, the direct capturing of the hand using an additional device, such as the hand tracking function of the Oculus Quest or the leap motion device, has been shown effective.…”

“…Studies are being performed on applications, such as user interfaces and haptic feedback, and various approaches are being taken toward this technology. [1][2][3] Immersive VR can improve the user's presence by providing a realistic experience regarding who and where the user is and how they behave. To do this, researchers are broadly studying displays that convey 3D visual information, methods for providing a sense of space using audio sources, interactions using hands, feet, gaze and haptic systems that use physical reactions as feedback.…”

This study proposes simple, highly immersive x-person asymmetric interactions that account for the experience type characteristics of asymmetric virtual environments, jointly experienced by virtual reality (VR) users and augmented reality (AR) users. The first person interactions for VR users are performed through the use of hand gestures, and they define a manipulation process that maps the gestures and object control scheme to provide intuitive interactions with the virtual environment and objects. The third person interaction for AR users is designed to view the overall virtual scene and recognize and judge situations to allow for intuitive communication and interactions among the virtual environment, objects, and users based on a touch interface. The core goal of this process is to provide all users who participate in asymmetric virtual environments with satisfying experiences and presence through individualized experience modes and roles. To this end, an application that uses the x-person asymmetric interactions was created. Furthermore, a survey experiment is performed to statistically analyze the interactions and verify that they provided users with a satisfactory experience, that is, a satisfactory sense of presence and social presence in each user's situation.

“…In addition, immersive interaction via hands was not considered. We aim to address the hand interaction issue in future work by incorporating a hand-tracking sensor similar to Leap Motion controller and a system for hand gripping [ 49 ]. In addition, the third-person viewpoint with a fixed position, which was used in this study, cannot be applied to large-scale scenes.…”

We propose a low-asymmetry interface to improve the presence of non-head-mounted-display (non-HMD) users in shared virtual reality (VR) experiences with HMD users. The low-asymmetry interface ensures that the HMD and non-HMD users’ perception of the VR environment is almost similar. That is, the point-of-view asymmetry and behavior asymmetry between HMD and non-HMD users are reduced. Our system comprises a portable mobile device as a visual display to provide a changing PoV for the non-HMD user and a walking simulator as an in-place walking detection sensor to enable the same level of realistic and unrestricted physical-walking-based locomotion for all users. Because this allows non-HMD users to experience the same level of visualization and free movement as HMD users, both of them can engage as the main actors in movement scenarios. Our user study revealed that the low-asymmetry interface enables non-HMD users to feel a presence similar to that of the HMD users when performing equivalent locomotion tasks in a virtual environment. Furthermore, our system can enable one HMD user and multiple non-HMD users to participate together in a virtual world; moreover, our experiments show that the non-HMD user satisfaction increases with the number of non-HMD participants owing to increased presence and enjoyment.

“…The EMG sensor is worn on the forearm, and when the user grasps, the degree of muscle exertion can be monitored when it is taken, and corresponding visual feedback is provided according to the magnitude of the force. The feedback includes the swing amplitude, expression, movement trajectory of the virtual avatar's hand, or the performance of the corresponding object when subjected to different forces in real life, and guide the user uses the appropriate force to interact with the virtual object [57]. Similarly, another researcher proposed that a similar EMG signal acquisition device can be used to compare the actual force used by the user with the weight of the target virtual object.…”

Virtual reality (VR) technology can provide users with an immersive experience as if they are in the real world, which can be applied in the fields of entertainment, education and scientific research, etc. In order to improve the sense of presence and immersion in VR, the design of multimodal feedback is an important component. In particular, the simulation of weight of virtual objects poses many challenges due to the limitations of hardware and software. Many researchers focused on this issue in various ways. These methods are mainly divided into two categories: device-based simulation and software-based simulation. This paper investigates the focus of software-based simulation, particularly for the virtual feedback methods proposed by researchers in recent years. We introduce the background of these proposed methods, technical implementation principles, application scenarios, the advantages and disadvantages of these simulation methods, and the evaluation criteria. We also propose the future challenges and the development of simulation methods for weight perception of virtual objects in VR.
