“…The recalibration hypothesis is that walking through the virtual environment with visual feedback modifies the perception-action coupling (Richardson & Waller, 2007;Waller & Richardson, 2008), such that recalibration changes the imagined rate of movement through the environment during subsequent blind walking. Recalibration of walking has been shown to transfer to other translational movements, such as crawling (Withagen & Michaels, 2002) and side-stepping (Rieser et al, 1995), but it does not transfer to different categories of responses, such as throwing (Rieser et al, 1995). Taken together, these findings support the functional account of recalibration (Rieser, 1999;Rieser et al, 1995), whereby recalibration transfers within a functional category of action, such as translation or rotation, but not across categories.…”

Egocentric distances in virtual environments are commonly underperceived by up to 50 % of the intended distance. However, a brief period of interaction in which participants walk through the virtual environment while receiving visual feedback can dramatically improve distance judgments. Two experiments were designed to explore whether the increase in postinteraction distance judgments is due to perception-action recalibration or the rescaling of perceived space. Perception-action recalibration as a result of walking interaction should only affect action-specific distance judgments, whereas rescaling of perceived space should affect all distance judgments based on the rescaled percept. Participants made blind-walking distance judgments and verbal size judgments in response to objects in a virtual environment before and after interacting with the environment through either walking (Experiment 1) or reaching (Experiment 2). Size judgments were used to infer perceived distance under the assumption of size-distance invariance, and these served as an implicit measure of perceived distance. Preinteraction walking and size-based distance judgments indicated an underperception of egocentric distance, whereas postinteraction walking and size-based distance judgments both increased as a result of the walking interaction, indicating that walking through the virtual environment with continuous visual feedback caused rescaling of the perceived space. However, interaction with the virtual environment through reaching had no effect on either type of distance judgment, indicating that physical translation through the virtual environment may be necessary for a rescaling of perceived space. Furthermore, the size-based distance and walking distance judgments were highly correlated, even across changes in perceived distance, providing support for the sizedistance invariance hypothesis.Keywords Visual perception . Distance perception . Virtual reality . Action Immersive virtual reality technology has numerous applications, including physical and psychological rehabilitation, education, training, entertainment, and human behavioral research. In order to be fully effective in these applications, virtual environments should be perceived as realistic representations of actual environments. One consistent challenge in creating realistic virtual environments is the tendency for underperception of distances, resulting in virtual environments that appear smaller than their real-world counterparts.In real environments under full-cue viewing, the perception of egocentric distance-the distance from oneself to an object -can be quite accurate. Perceived egocentric distance has been measured in multiple ways, including verbal numerical report (da Silva, 1985;Foley,

“…Withagen and Michaels's (2002) results, in which overshoot is simply larger after walking on a treadmill for 15 min at 6 km/h than it is at 3 km/h, are not good evidence that the CAVE played a role in moderating the aftereffect. Durgin and Pelah (1999) reported that supplying artificial optical flow to treadmill runners by means of a single (120°wide) wall display of expanding visual flow had no influence on the amount of resulting drift.…”

Do locomotor aftereffects depend specifically on visual feedback? In 7 experiments, 116 college students were tested, with closed eyes, at stationary running or at walking to a previewed target after adaptation, with closed eyes, to treadmill locomotion. Subjects showed faster inadvertent drift during stationary running and increased distance (overshoot) when walking to a target. Overshoot seemed to saturate (i.e., reach a ceiling) at 17% after as little as 1 min of adaptation. Sidestepping at test reduced overshoot, suggesting motor specificity. But inadvertent drift effects were decreased if the eyes were open and the treadmill was drawn through the environment during adaptation, indicating that these effects involve self-motion perception. Differences in expression of inadvertent drift and of overshoot after adaptation to treadmill locomotion may have been due to different sets of ancillary cues available for the 2 tasks. Self-motion perception is multimodal.

“…We take calibration to bear on the relation between the perceptual information exploited and the subsequent perception or action. More precisely, calibration is the process that establishes and maintains the appropriate relation between the informational variable and the perception or action (e.g., Jacobs & Michaels, 2006;Withagen & Michaels, 2002. In some places, we use the term recalibration to emphasize a change in existing calibration values.…”

“…Calibration in perception-action has received considerable attention lately (e.g., Adolph & Avolio, 2000;Bhalla & Proffitt, 1999;Bingham et al, 2000;Jacobs & Michaels, 2006;Mark, 1987;Pick et al, 1999;Redding & Wallace, 1997a;Wagman et al, 2001;Withagen & Michaels, 2002. Among the issues addressed is the organization of calibration.…”

“…Berry and Rieser (1999) found further evidence for a functional organization of calibration by showing that the recalibration of turning in place by using the legs partially transferred to turning in place by using the arms. Later, Withagen and Michaels (2002) showed that the calibration of walking without vision to a seen place generalized to crawling without vision to a seen place. And Bruggeman, Pick, and Rieser (2001) found that the directional calibration of underhand throwing generalized to the direction of overhand throwing but not to walking direction.…”
