“…Here, the walking movement corresponds to a different walking movement in VR due to spatial restrictions. Another example of visuomotor illusions is reach redirection, which allows targets to be reached that are beyond actual reach while maintaining some semblance of body ownership (Cohn et al 2020;Gonzalez et al 2022). Furthermore, discrepancies between perception and movement are intentionally built in as part of the VR experience.…”

Sensorimotor adaptation in virtual reality: Do instructions and body representation influence aftereffects?

Perturbations in virtual reality (VR) lead to sensorimotor adaptation during exposure, but also to aftereffects once the perturbation is no longer present. An experiment was conducted to investigate the impact of different task instructions and body representation on the magnitude and the persistence of these aftereffects. Participants completed the paradigm of sensorimotor adaptation in VR. They were assigned to one of three groups: control group, misinformation group or arrow group. The misinformation group and the arrow group were each compared to the control group to examine the effects of instruction and body representation. The misinformation group was given the incorrect instruction that in addition to the perturbation, a random error component was also built into the movement. The arrow group was presented a virtual arrow instead of a virtual hand. It was hypothesised that both would lead to a lower magnitude and persistence of the aftereffect because the object identity between hand and virtual representation would be reduced, and errors would be more strongly attributed to external causes. Misinformation led to lower persistence, while the arrow group showed no significant differences compared to the control group. The results suggest that information about the accuracy of the VR system can influence the aftereffects, which should be considered when developing VR instructions. No effects of body representation were found. One possible explanation is that the manipulated difference between abstract and realistic body representation was too small in terms of object identity.

“…Despite the various efforts described above, only a few studies [12,61,62] have considered combining user redirection with dynamic haptics. Examples include redirection techniques that provide constant haptic cues while walking using a tethered wheeled robot [61] or moving tables [62], but none of them have investigated the haptic cues of opening doors.…”

“…To improve this, the opening angle for each user could be individually learned over trials to increase the accuracy of the approximation process in Goal Determiner, which could save time for the subsequent fine-tuning process. Another consideration is that redirection with our system could be used to reduce the robot placement delay (i.e., by steering the user through redirection so that the robot can be in place at the right time), as in previous work [12].…”

“…E-mail: yukai.hoshikawa.r4@alumni.tohoku.ac.jp, k-fujita,takashima,kitamura@riec.tohoku.ac.jp. were studied in different contexts than the above-mentioned limitations of a physical play area; very few studies [12,61,62] have considered combining dynamic haptics with redirection. RedirectedDoors (RDD) [17,18], which is a redirection technique focusing on the door-opening motion in VR, is an approach that potentially address both challenges (i.e., limited physical play area and inadequate haptic feedback) simultaneously.…”

Wheel robot with a doorknob Redirected!! Opening door in VR Fig. 1: Overview of RedirectedDoors+. (a) The system provides the user with haptic feedback of opening doors in room-scale VR by adaptively controlling a small number of wheel robots with a doorknob prop. (b-c) During door opening, the system rotates the entire virtual environment by a specific amount, thus steering the user away from the boundary of the play area.

“…The solution is designed to ensure collision avoidance and communication topology, with experimental results verified in a VR environment. In [ 14 ], an illusion-based VR interaction technique is proposed where the virtual hand of a user is moved during a reach to guide their physical hand to a specific location. The proposed method is validated for developing a control approach to achieve redirection and desired point and path tracking.…”

In this article, we present a novel approach to performing engineering simulation in an interactive environment. A synesthetic design approach is employed, which enables the user to gather information about the system’s behaviour more holistically, at the same time as facilitating interaction with the simulated system. The system considered in this work is a snake robot moving on a flat surface. The dynamic simulation of the robot’s movement is realised in dedicated engineering software, whereas this software exchanges information with the 3D visualisation software and a Virtual Reality (VR) headset. Several simulation scenarios have been presented, comparing the proposed method with standard ways for visualising the robot’s motion, such as 2D plots and 3D animations on a computer screen. This illustrates how, in the engineering context, this more immersive experience, allowing the viewer to observe the simulation results and modify the simulation parameters within the VR environment, can facilitate the analysis and design of systems.
