“…We believe that this may have implications for further neurobehavioral work in experimental psychology, as well as with respect to designing more immersive and realistic tool-use experiences in other AR application contexts. For example, further work on this intersection could contribute to our understanding of challenging real-world use cases, such as requirements for BS malleability in the context of virtually operating theatres (see, e.g., Zaman et al 2019). Together, our findings thus substantially extend previous studies by demonstrating how even virtual tools become incorporated into the BS, while adding to our understanding of the respective roles of visual and haptic feedback in virtual tool-use training in general.…”

In this study we examined if training with a virtual tool in augmented reality (AR) affects the emergence of ownership and agency over the tool and whether this relates to changes in body schema (BS). 34 young adults learned controlling a virtual gripper to grasp a virtual object. In the visuo-tactile (VT) but not the vision-only (V) condition, vibro-tactile feedback was applied to the palm, thumb and index fingers through a CyberTouch II glove when the tool touched the object. Changes in the forearm BS were assessed with a tactile distance judgement task (TDJ) where participants judged distances between two tactile stimuli applied to their right forearm either in proximodistal or mediolateral orientation. Participants further rated their perceived ownership and agency after training. TDJ estimation errors were reduced after training for proximodistal orientations, suggesting that stimuli oriented along the arm axis were perceived as closer together. Higher ratings for ownership were associated with increasing performance level and more BS plasticity, i.e., stronger reduction in TDJ estimation error, and after training in the VT as compared to the V feedback condition, respectively. Agency over the tool was achieved independent of BS plasticity. We conclude that the emergence of a sense of ownership but not agency depends on performance level and the integration of the virtual tool into the arm representation.

“…To overcome these issues, a combination of physical mock-up and virtual reality (VR) hardware can be utilized to simulate MR interventions in virtual radiology suites [30,38]. This approach allows for testing of early prototypes, drawing valuable conclusions that can be applied in real-world scenarios without requiring access to an MR device [34,54]. Recent developments in VR technology enable compelling simulations and practice scenarios.…”
