“…Likewise, any locomotion technique that preserves the full set of body-based cues would also be considered concordant (note that most treadmills do not meet this criterion, as described below). Redirected walking [3], whereby users are steered away from physical obstacles by subtle separation between real and virtual rotation, could also be considered concordant in cases in which redirection is below perceptual thresholds for detection [16,37].…”

Virtual reality systems typically allow users to physically walk and turn, but virtual environments (VEs) often exceed the available walking space. Teleporting has become a common user interface, whereby the user aims a laser pointer to indicate the desired location, and sometimes orientation, in the VE before being transported without self-motion cues. This study evaluated the influence of rotational self-motion cues on spatial updating performance when teleporting, and whether the importance of rotational cues varies across movement scale and environment scale. Participants performed a triangle completion task by teleporting along two outbound path legs before pointing to the unmarked path origin. Rotational selfmotion reduced overall errors across all levels of movement scale and environment scale, though it also introduced a slight bias toward under-rotation. The importance of rotational self-motion was exaggerated when navigating large triangles and when the surrounding environment was large. Navigating a large triangle within a small VE brought participants closer to surrounding landmarks and boundaries, which led to greater reliance on piloting (landmark-based navigation) and therefore reduced-but did not eliminatethe impact of rotational self-motion cues. These results indicate that rotational self-motion cues are important when teleporting, and that navigation can be improved by enabling piloting.

“…In addition, Bachmann et al [5] used artificial potential fields to apply RDW and reset algorithms that consider physical obstacles and users. More recently, Williams et al [47] proposed an alignmentbased redirection controller called ARC, displaying the state-of-art performance of real-time, space-adaptive redirection technique that enables free movement.…”

“…Redirection controllers are algorithms that are used to compute the correct redirection that is applied to optimally steer the user away from physical objects [24]. The performance of controllers is typically evaluated by measuring the number of times the user is reset after getting too close to a physical object [4,23,38,43,44], the average distance the user is able to walk before initiating a reset [4,35,38,43], or the average strength of redirection during locomotion [4,22,43]. These performance metrics are useful, but they do not provide any information in terms of how similar is the user's proximity to obstacles in the PE and VE.…”

Figure 1: A visualization of our Environment Navigation Incompatibility (ENI) scores for physical environment paired with three different virtual environments with increasing environment area. Our metric is used to accurately quantify whether it is possible to compute a good mapping between the geometric layouts of these environment. We sample points across the virtual environment to represent the user's position (shown as colored circles) and compute the corresponding point in the physical environment based on comparing the local neighborhoods. Overall, our metric helps us to determine which regions or subsets of the VE are more compatible with the PE. Through this visualization, we can see which regions of the VE are more or less compatible with the PE.
