“…Furthermore, users preferred the controller interaction, and the feedback of the controller was more comfortable. Dalia Blaga et al (2021) investigated the implementation of natural fetching in VR environments. They used a virtual hand model to map the real hand, allowing the participants to grab 16 different virtual objects during the task.…”

Virtual reality (VR) technology is developing rapidly, and many 3D virtual simulation experiments on the web can be quickly ported to the VR environment to enhance user experience. The manner of interacting with a quickly ported two-dimensional user interface (2DUI) is a matter of preference. In this study, we focused on finding a more effective interaction scheme when a web 3D virtual simulation experiment is ported into the VR environment. When the development time is short, ray interaction and touch interaction can be easily and quickly ported while retaining the 2DUI of the original web-side experiment. We selected the architecture optics virtual simulation experiment for porting, divided the interactions into two levels, namely, L1 ray and L2 touch interactions, and recruited 30 volunteers to participate in the experiment in groups. The efficiency and user experience of L1 and L2 were compared by designing interactive tasks and collecting data. Overall, L1 was more efficient than L2. For the four common user interfaces, buttons, sliders, toggles, and dropdowns, L2 was only slightly better at interacting with the dropdown boxes than L1. However, both were slower than the web interface. L2 also received higher workload scores, based on user feedback and workload surveys. We also designed an interaction level, L3, for VR with reference to Worlds in Miniature and compared it with L1/L2/web by using the same interaction tasks. L3 was as efficient as the web. Finally, based on the experimental results, we provide suggestions for quick porting development.

“…For this, there is a need for complex physics-based simulations that infer object behavior from the position and properties of the individual fingers (Höll et al, 2018). As the contact points between fingers and surface change according to how the object moves within the hand, the adaption of the grasping pose must be determined dynamically, as previous work explored for freehand grasping (Dalia Blaga et al, 2021).…”

Some virtual reality (VR) applications require true-to-life object manipulation, such as for training or teleoperation. We investigate an interaction technique that replicates the variable grip strength applied to a held object when using force-feedback gloves in VR. We map the exerted finger pressure to the rotational freedom of the virtual object. With a firm grip, the object’s orientation is fixed to the hand. With a loose grip, the user can allow the object to rotate freely within the hand. A user study (N = 21) showed how challenging it was for participants to control the object’s rotation with our prototype employing the SenseGlove DK1. Despite high action fidelity, the grip variability led to poorer performance and increased task load compared to the default fixed rotation. We suspect low haptic fidelity as an explanation as only kinesthetic forces but no cutaneous cues are rendered. We discuss the system design limitations and how to overcome them in future haptic interfaces for physics-based multi-finger object manipulation.

“…To avoid the limitation of controller-based methods, we incorporate tracking-based techniques to achieve more natural and realistic free-hand perception [26], allowing for natural interactions with virtual objects. Our system enhances the user experience by providing highlighting hand avatars upon contact.…”
