“…Redirection techniques have to date been investigated in many situations such as redirected walking [42], [43], [51], [52], hand remapping and redirected touching [1], [10], [25], [33], [63], jumping [17], [32] and head rotations [46], [51]. The main goal of these techniques is to overcome the problems of limited space or physical incapabilities [58].…”

Head tracking in head-mounted displays (HMDs) enables users to explore a 360-degree virtual scene with free head movements. However, for seated use of HMDs such as users sitting on a chair or a couch, physically turning around 360-degree is not possible. Redirection techniques decouple tracked physical motion and virtual motion, allowing users to explore virtual environments with more flexibility. In seated situations with only head movements available, the difference of stimulus might cause the detection thresholds of rotation gains to differ from that of redirected walking. Therefore we present an experiment with a two-alternative forced-choice (2AFC) design to compare the thresholds for seated and standing situations. Results indicate that users are unable to discriminate rotation gains between 0.89 and 1.28, a smaller range compared to the standing condition. We further treated head amplification as an interaction technique and found that a gain of 2.5, though not a hard threshold, was near the largest gain that users consider applicable. Overall, our work aims to better understand human perception of rotation gains in seated VR and the results provide guidance for future design choices of its applications.

“…Visuo-haptic illusions have been shown to improve presence and interactivity in VR [3,17,30], and appears as a viable way to reduce cost and complexity to set-up a virtual training environment. However, when motor skills are involved, they may induce a negative effect as suggested by studies in visuo-motor adaptation.…”

“…For instance, users can believe interacting with a large collection of physical objects while, in fact, they only interact with a unique physical prop [3]. This emerging approach has been shown to enrich user experience: It provides realistic haptics [3], expands the interaction space [37] or augment interactivity [30,52]. However, visuo-haptic illusions has not been investigated in the context of skill transfer.…”

In this article we investigate the potential of using visuo-haptic illusions in Virtual Reality environment to learn motor skills in a real environment. We report on an empirical study where 20 participants perform a multi-object pick-and-place task. The results show that although users do not perform the same motion trajectories in the virtual and real environments, skills acquired in VR augmented with visuo-haptic illusions can be successfully reused in a real environment: There is a high amount of skill transfer (78.5%), similar to the one obtained in an optimal real training environment (82.4%); Finally, participants did not notice the illusion and were enthusiastic about the VR environment. Our findings invite designers and researchers to consider visuo-haptic illusions to help operators to learn motor skills in a cost-effective environment.

“…Warping on planar surfaces would allow users to take advantage of a larger workspace in VR with a small tactile surface for haptic feedback. Although there are studies on bimanual retargeting [56] or unimanual redirected touching that used planar surfaces in their experiments [44,45], none studied the planar surface as a means of input method. Large displays are known to offer performance benefits on spatial tasks, spatial knowledge, and navigation [7,72,73].…”
