“…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.

Grasping is the most natural and primary interaction paradigm people perform for every-day manual tasks in reality. However, while grasping real objects in Real Environments (RE) has been highly explored in literature, there is a recent emerging trend to explore the complications and nuances of hand interaction including grasping in Virtual Environments (VE). While this is leading towards a richer body of work to understand users' approach to grasping in VE, a direct comparison between grasping real objects in RE and grasping virtual representations of real objects in VE has not been explored before. To address this gap, we perform a user study (n=20) on 7 representative real objects and their virtual twins from the "Yale-Carnegie Mellon University-Berkeley Object and Model Set". We report on 840 grasp instances collected during a grasp and translate task across RE and VE. We present initial results on the observed differences between RE and VE grasping across the different objects using the grasp type metric from real grasping studies. We explore the rationale for any observed differences between the RE and VE and present indicative trends for VE grasping. Finally, we propose methods and approaches for furthering work within VE grasping for improving the natural grasping interface.
