“…In a different sporting context, the performance of handball goalkeeper was analyzed by making use of video and virtual reality, which showed a more effective, accurate and anticipated performance through virtual reality. According to Vignais et al [4], this may be due to the fact that by means of virtual reality more perceptual information is obtained compared to the two dimensions in a video. In our study, both the type of information demanded and the internal logic of the sport subject to the study may well explain the obtained results.…”

“…The reason for this is that the type and number of stimuli in collective sports is completely different from the ones in climbing. In this sense, Vignais et al [4], point out the importance of the effect of virtual reality on the perception of information and anticipation of the adversary (the latter being non-existent in escalation). This statement establishes that virtual reality is capable of simulating real situations to the maximum that add relevant information for the athlete to improve their performance in a real game situation.…”

“…In the same line, Vignais, Kulpa, Brault. Presse & Bideau [4], comment on the importance of virtual reality on the work of information perception and anticipation of the adversary's movement. Alongside this, they establish that the virtual reality is able to simulate real situations at their highest level while such situation is being controlled by the experimenter, who can modify them.…”

This paper analyses the effect of virtual reality visualization (VRV) on climbers, with respect to the traditional visualization methodology. The study sample was made up of 21 novel climbers: Control Group CG (N=7), Traditional Visualization Group TVG (N=7) and Virtual Reality Group VRG (N=7). In order to implement the mental imagery through virtual reality, a 360º Ricoh Theta S camera and a pair of Woxter Neo VR1 goggles were used. The data analysis was carried out with a simple ANOVA of three means. No statistically signifi cant differences were found. The results are discussed and future lines of research are established.

“…Due to this fact martial arts training becomes more and more popular in all group ages from preschool children to retiree. Because of the large popularity of that sport there is also a need of computer aided methods and applications that support training [67,69]. The second reason is that karate has a large group of well defined "standardized" attacking and defense techniques that are practiced by athletes.…”

In this paper we propose, describe and evaluate the novel motion capture (MoCap) data averaging framework. It incorporates hierarchical kinematic model, angle coordinates' preprocessing methods, that recalculate the original MoCap recording making it applicable for further averaging algorithms, and finally signals averaging processing. We have tested two signal averaging methods namely Kalman Filter (KF) and Dynamic Time Warping barycenter averaging (DBA). The propose methods have been tested on MoCap recordings of elite Karate athlete, multiple champion of Oyama karate knockdown kumite who performed 28 different karate techniques repeated 10 times each. The proposed methods proved to have not only high effectiveness measured with root-mean-square deviation (4.04 ± 5.03 degrees for KF and 5.57 ± 6.27 for DBA) and normalized Dynamic Time Warping distance (0.90 ± 1.58 degrees for KF and 0.93 ± 1.23 for DBA), but also the reconstruction and visualization of those recordings persists all crucial aspects of those complicated actions. The proposed methodology has many important applications in classification, clustering, kinematic analysis and coaching. Our approach generates an averaged full body motion template that can be practically used for example for human actions Multimed Tools Appl (2018) 77:30353-30380 recognition. In order to prove it we have evaluated templates generated by our method in human action classification tasks using DTW classifier. We have made two experiments. In first leave -one -out cross -validation we have obtained 100% correct recognitions. In second experiment when we classified recordings of one person using templates of another recognition rate 94.2% was obtained.

“…Kuo et al [3] proposed a framework, in which, the elements of the system were illustrated by highlighting the emotional impacts, which were followed by each feedback during training. Some researchers [4] studied the application of virtual technique in handball, the goal of this study is to determine which of these technologies may be preferentially utilized to analyze visual information uptake during a sport situation. These findings suggested that the analysis of visual information uptake for handball goalkeepers was better performed by using a 'virtual reality'-based methodology.…”

Abstract-this research designed simulation system of gymnastics automatic choreography software. To successfully design the gymnastics movements, experiment adopted solutions based on key frame spline interpolation calculation which managed to solve the problem of location deviation; quaternion interpolation algorithm was adopted to solve the rotation problem of the subject and the body, which made the modified action by computer auxiliary choreography system completely returned to virtual figure animation. In addition, for coordination of dance and audio, this paper established movement fragments library based on sentiment types, proposed viable approach of synchronized audio and video model. Teaching experience was conducted in the gymnastics course of physical education at the University and achieved good results.
