“…One interpretation proposes that the participants might have felt trapped within the high density crowd once they were exposed to it. Thus, the participants may have decided to move with the flow of the crowd instead of attempting to free themselves from it, 32,43 as prior studies have shown that humans tend to coordinate with virtual characters when in their presence 46‐48 . Moreover, the direction and speed interaction effect suggests that our participants may have been more willing to follow the virtual crowd when it was moving at a low rather than a high speed.…”

“…Other studies have investigated the movement coordination of participants. Such studies have included real 40‐42 and virtual reality 43‐45 scenarios in which people coordinated their movements while crossing an intersection in the presence of either a human or virtual character. It has been found 46‐48 that two humans tend to become more sensitive to each other's presence and to simultaneously change their decisions or actions when crossing a road as part of a group, compared with when doing so on their own.…”

We investigated the movement behavior of participants walking within a virtual crowd in an immersive virtual environment. We investigated three different parameters that characterize a moving virtual crowd: density, speed, and direction. An immersive road-crossing scenario that took place in a virtual metropolitan city was created. In this scenario, the participants were instructed to walk toward the opposite sidewalk. Three measurements (speed, deviation, and trajectory length) were used to evaluate the impact of the parameters assigned to the virtual crowd on the movement behavior of the participants. Significant results were found for both the main and interaction effects. The results suggested that the high density, low speed, and diagonal direction situations associated with the virtual crowd had the greatest impacts on the speed, deviation, and trajectory lengths of participants when they walked in a virtual environment and were surrounded by a moving virtual population.

“…The results of this investigation also add to a growing body of literature on joint road crossing and joint action more generally Jiang et al, 2016;O'Neal, Jiang, Brown, Kearney, & Plumert, 2019). Judging gap affordances is more complicated when acting with another person because decisions must consider the action capabilities of both people.…”

Let’s Cross the Next One: Parental Scaffolding of Prospective Control Over Movement

This investigation examined parental scaffolding of children's prospective control over decisions and actions during a joint perception-action task. Parents and their 6-, 8-, 10-, and 12-year-old children (N = 128) repeatedly crossed a virtual roadway together. Guidance and control shifted from the parent to the child with increases in child age. Parents more often chose the gap that was crossed and prospectively communicated the gap choice with younger than older children. Greater use of an anticipatory gap selection strategy by parents predicted more precise timing of entry into the gap by children. This work suggests that social interaction may serve as an important experiential mechanism for the development of prospective control over decisions and actions in the perception-action domain.

The aim of our study was to investigate whether different tactile feedback conditions could affect the behavior of participants who were instructed to walk within a virtual reality environment surrounded by a virtual crowd of people. A road crossing scenario that takes place in a virtual metropolitan city was developed for this study. Participants were asked to walk toward the opposite sidewalk while wearing a tactile vest. At each road crossing, one of several tactile feedback conditions was generated, including No Tactile, Side Tactile, Back Tactile, Front Tactile, Accurate Tactile, and Random Tactile. During the virtual road crossing, the movement of the participants was captured, and movement‐related measurements were extracted and analyzed to evaluate the effects of tactile feedback on the participant's movement behavior. Additional data were collected through the distribution of a questionnaire to consider self‐reported ratings of the experimental conditions. The results revealed that tactile feedback conditions had significant effects on movement behavior, while the participants' ratings also indicated that they were affected by the tactile feedback conditions. We found that when the participants were immersed in a high‐density crowd simulation, they became sensitive to tactile feedback. However, they were not able to distinguish between the accurate feedback and the random feedback.
