“…Passive haptic feedback has been found to increase performance on Fitts's law tasks [33,64]. Similarly, an electrovibration haptic interface/display was observed to improve performance on a Fitts's law task [79]. Though, passive haptic feedback and haptic displays are not preferred in VR, since VR applications require haptic devices with increased wearability and portability [16,45,47,49].…”

While user's perception and performance are predominantly examined independently in virtual reality, the Action-Specific Perception (ASP) theory postulates that the performance of an individual on a task modulates this individual's spatial and time perception pertinent to the task's components and procedures. This paper examines the association between performance and perception and the potential effects that tactile feedback modalities could generate. This paper reports a user study (N=24), in which participants performed a standardized Fitts's law target acquisition task by using three feedback modalities: visual, visuo-electrotactile, and visuo-vibrotactile. The users completed 3 Target Sizes × 2 Distances × 3 feedback modalities = 18 trials. The size perception, distance perception, and (movement) time perception were assessed at the end of each trial. Performance-wise, the results showed that electrotactile feedback facilitates a significantly better accuracy compared to vibrotactile and visual feedback, while vibrotactile provided the worst accuracy. Electrotactile and visual feedback enabled a comparable reaction time, while the vibrotactile offered a substantially slower reaction time than visual feedback. Although amongst feedback types the pattern of differences in perceptual aspects were comparable to performance differences, none of them was statistically significant. However, performance indeed modulated perception. Significant action-specific effects on spatial and time perception were detected. Changes in accuracy modulate both size perception and time perception, while changes in movement speed modulate distance perception. Also, the index of difficulty was found to modulate all three perceptual aspects. However, individual differences appear to affect the magnitude of action-specific effects. These outcomes highlighted the importance of haptic feedback on performance, and importantly the significance of action-specific effects on spatial and time perception in VR, which should be considered in future VR studies.

Over the last five years, virtual reality (VR) has become more popular in pediatric physiotherapy. In this study, we assessed the feasibility and acceptability of measuring upper-limb movements in typically-developing children and adolescents using an immersive virtual reality (iVR) headset. Thirty-six typically-developing children (age: 12 ± 2.1 y) were recruited and required to draw circles in a custom-built virtual environment using a Meta-Quest-2 headset. Outcomes were the System Usability Scale (SUS), Developmental Coordination Disorder-Questionnaire (DCD-Q), and three metrics of circle drawing performance (movement time, mean velocity and circle roundness). The mean score for the SUS was 74 ± 11, indicating good levels of acceptability and usability when the participants used the headset. No strong relationships were observed between the circle drawing metrics and DCD-Q scores (rho = < 0.3, p = > 0.05), but circle roundness ratios were positively and significantly correlated with SUS scores (rho = 0.5, p = 0.003). No adverse effects associated with iVR use were reported for any participants. This study showed that iVR is a viable method to measure upper-limb motor performance in children and adolescents, highlighting the potential value of this tool in pediatric physiotherapy practice.
