“…Lastly, in a very recent study the so far positive relationship between ownership and performance was challenged by the notion of risk of danger in the context of VR-based machinery teleoperation (Shin et al, 2021). Participants performed pick and place tasks on a conveyor belt, during which a "raw material" had to be placed in a metal press machine for quick pressing (high risk) or slow pressing (low risk), using either a realistic hand or a robot hand.…”

“…For example, Grechuta et al found clear positive correlations between body ownership and performance in various tasks in VR (Grechuta et al, 2017;Grechuta et al, 2019). In contrast, Shin et al found that greater body ownership may cause an increased risk perception, which in turn leads to degraded performance in pick-and-place tasks in VR (Shin et al, 2021).…”

In teleoperations, robots are generally used because related tasks are too dangerous, uncomfortable or impossible for humans to perform. When using augmented reality to control robotic limbs in such teleoperations, it is essential to understand how these extra virtual limbs are experienced. In particular, the relationship between the embodiment experience of the user and relevant outcomes such as task performance must be examined. In this article, we study the relationship between experienced embodiment of a supernumerary virtual arm that acts alongside a user’s two real arms, and their task performance in augmented reality. Specifically, we compare how well users can trace a virtual half ring placed just outside of personal space using their virtual arm in a condition where there is expected to be low embodiment (a floating disconnected hand) and a condition where there is expected to be high embodiment (a connected arm and hand). Embodiment is measured quantitatively through skin conductance response and qualitatively through ownership, agency, and self-location questionnaires. Performance is measured in terms of tracing precision. The results show positive correlations between subjective ownership and agency, and agency and performance, but no correlation between subjective or objective ownership and performance. Also, ownership ratings were low overall, while the agency ratings were significantly higher for the disconnected hand condition than the connected arm condition, as was performance. Notably, the presence of the virtual arm evoked incorrect expectations of the movement capabilities of the arm, which may have contributed to an overall preference for the unrealistic disconnected hand over the more realistic connected arm in this particular task. Our results imply that methods to increase performance in various teleoperations can indeed be found in the experience of embodiment: not necessarily directly through ownership, but through ownership mediated by agency.

The interaction of user performance with three-dimensional (3D) objects has become an important issue in the recent development of virtual reality applications. Additionally, the basic conviction of current Virtual Reality (VR) supports the development of the viable interface between humans and machines. The research focuses on the user’s interaction technique by considering two approaches (direct and indirect interaction techniques) for the users while interacting with threedimensional objects. Numerous possible uses can benefit from virtual reality by considering a few fundamental visual and cognitive activities in the Virtual Environment (VE), such as the interpretation of space that users of clear and indirect perception are not well established. The experiment is performed in a stereoscopic environment using a reciprocal tapping task. Participants are expected to use direct pointing as well as indirect cursor techniques to select a stereoscopic spherical target. The results show that, in the sense of a direct interaction technique, user recognition of an object appears to converge in the center of a simulated area. Unfortunately, this convergence is not demonstrated in the indirect cursor situation. The pointing estimation from the users is more accurate when using the indirect interaction approach. The findings provide an understanding of the interaction characteristics done by the users in the stereoscopic environment. Importantly, developers of a virtual environment may use the result when developing effective user interface perception in specific interaction techniques.

“…The arm's visual human-likeness refers to the humanlikeness and appearance fidelity of the embodied objects such as a robotic hand. The more the object one is controlling is similar to the real body, the higher will be the operator's SoE (Mick et al, 2020;Shin et al, 2021).…”

A range of perceptual cues drive the Sense of Embodiment (SoE) with an external object, such as a virtual arm that looks like one's own or can be controlled like one's own. Since most experiments test one or two cues at a time, it is difficult to establish their relative contribution and possible interaction. This work aims at investigating the importance of five key perceptual cues (field of view, visuo-proprioceptive synchronicity, tactile feedback, visual human likeness, and connectedness) and their potential interaction in a single, full-factorial experiment. Participants touched a target dot, which changed position after a hit, for 1 min in a virtual environment seen through a head-mounted display. Participants' arm and hand motions were mapped to a virtual arm and hand. All perceptual cues had two levels: SoE supportive and SoE suppressive. Twenty-eight participants completed the task in all possible combinations. We recorded Task Performance and self-ratings of Sense of Ownership and Sense of Agency. Results showed that visuo-proprioceptive synchronicity had the largest effect on all three measures. The relative importance of the remaining four cues differed for the three dependent variables. The cues did not have significant interactive effects. We conclude that when designing an interface for maximum supportive embodiment, visuo-proprioceptive synchronicity is the most important perceptual cue. The extent to which other supportive cues can improve the embodiment experience depends on the considered variables, but generally, the more other supportive cues can be added, the better.
