“…It seems that angular velocity might have provided the necessary information for the prospective control of movement in the ball carrier (Bastin, Craig, & Montagne, 2006;Corrêa et al, 2012b;Fajen, Riley, & Turvey, 2009). These interpretations are in line with data outlining the influence of spatiotemporal measures, such as the time-to-contact and relative velocity information on decision-making in team games like basketball, football, futsal, and rugby union (see Correia & Araújo, 2009;Correia et al, 2011;Duarte et al, 2010a;Passos et al, 2008Passos et al, , 2009Travassos et al, 2012;Watson et al, 2011). Similar to those above cited information, angular velocity could supply the essential information for players to make decisions because it couples space and time constraints, which afford prospective guidance of movements.…”

The aim of this study was to investigate the influence of interpersonal interactions between players on the regulation of ball passing velocity in the team sport of futsal. For this purpose 28 sequences of play, in which passes were performed between outfield players, were selected from an elite futsal competition and analyzed using TACTO software. Relative angles between attackers and defenders were used to examine interpersonal coordination tendencies that emerged during performance. Results showed that ball passing velocity was constrained by the rate of change of the angle created by the following vectors: "ball carrier-ball receiver" and "ball carrier-ball receiver's nearest defender". Passing velocity remained the same when that angular value remained within a critical threshold range between −18.16˚/s to 11.26˚/s. Beyond those critical threshold values, angular relations between participants seemed to enter into a new critical state requiring the emergence of a new passing velocity for performance success. The findings of this study allowed us to conclude that passing velocity during competitive performance in futsal was regulated by the rate of change of an angle established by the interaction between the ball carrier to ball receiver vector with the ball carrier to ball receiver's nearest defender vector.

“…As this implies a gap (of constant size) moving at constant velocity, such an experimental design does not allow separating out the effects of local and global contributions. The same holds for studies in which the size of a (stationary) gap was changed during the course of a trial by equal and symmetrical lateral movement of the two gap boundaries, whether participants had to judge passability (Fajen & Matthis, 2011;Watson et al, 2011) or regulate approach speed so as to pass through the aperture (e.g., Montagne, Buekers, Camachon, De Rugy, & Laurent, 2003).…”

In real situations, analyzing the contribution of different parameters on sports performance is a difficult task. In a duel for example, an athlete needs to anticipate his opponent's actions to win. To evaluate the relationship between perception and action in such a duel, the parameters used to anticipate the opponent's action must then be determined. Only a fully standardized and controllable environment such as virtual reality can allow this analysis. Nevertheless, movement is inherent in sports and only a system providing a complete freedom of movements of the immersed subject (including displacements) would allow the study of the link between visual information uptake and action, that is related to performance. Two case studies are described to illustrate such use of virtual reality to better understand sports performance. Finally, we discuss how the introduction of new displacement devices can extend the range of applications in sports. IntroductionSport is gaining an increasing place in nowadays societies, not only as an entertainment but also as a socio-economical matter. There is now overwhelming evidence that regular physical activity has important and wide-ranging benefits on health [14]. Moreover, sport offers great pedagogical values for young people. It conveys moral values and requires appropriate behaviors in groups. As a consequence, studying sports becomes more and more important, not only to better understand performance
