Exploratie van inzet mixed reality (AR en VR) voor sport skills training in de breedtesport. Vanuit de breedtesport wordt gekeken hoe technologie gebruikt kan worden ter ondersteuning en versterking van de sport, bijvoorbeeld door trainers te ondersteunen in het maken van motiverende oefeningen of voor blessurepreventie. Vanuit technologisch perspectief wordt het inzetten van mixed reality steeds eenvoudiger. De afgelopen jaren hebben wij daarom met studenten gekeken naar de inzet van virtual reality (VR) en Augmented Reality (AR) om sport skills training te ondersteunen. We bespreken hier vier projecten: twee over het gebruik van de Hololens (AR) voor indoor ski-training, één voor roeien op een ergometer in VR met persoonlijke feedback, en één voor het trainen van de ontvangst in volleybal in VR. De studenten, vaak zelf met sportervaring, hebben de verschillende toepassingen gemaakt met behulp van input en feedback van sporters, exploitanten en docentonderzoekers. Elk project heeft exploratieve user studies gedaan met medestudenten. Behalve een positief eerste ontvangst hebben we gereflecteerd op het spectrum van deze 4 projecten. Daar zien wij twee dingen er uit springen. De eerste is de rol van de trainer. We zien dat er vaak de krachtigste combinatie is als de technische tool een verlengstuk is van de trainer, maar dat dit niet noodzakelijk zo is voor elke oefeningsvorm, terugkijkend op dit werk relateert sterk aan de transformatie tips van Jesse Schell in zijn boek the Art of Game Design. Ten tweede zien we door het naast het elkaar zetten van de 4 oefeningen een verschil in hoe sport-specifiek en realistisch de VR/AR oefening moet zijn. Soms is het belangrijk dat de oefening zo dicht mogelijk bij een wedstrijduitvoering ligt, maar dat hoeft niet altijd. Dit relateert sterk aan het door Ishii et al. (1999) geïdentificeerde spectrum van “augmentation to transform”. Door het uiteenzetten deze twee dimensies en het tonen van de concepten hoop handvatten te leveren voor ontwikkeling en samenwerking tussen verschillende betrokken disciplines in de richting van technologie voor de sport.

- Injury prevention in general, and improvement, One aspect they found with interviewing their (lower level) trainers was the posture for recieving
- Two rounds of user tests were executed. The first round of user tests was done by 17 test participants. From this round it became clear that people did not realize that the red blocks were obstacles that needed to be avoided. Therefore, 4 of the test participants were invited to do a second round of user tests, in which the game was updated to the version that was shown on the previous slide. During the user tests, people were presented to questions from the simulator sickness questionnaire, the intrinsic motivation inventory, and some questions that were specifically related to the skiing game. For the SSQ questions people could indicate how much they were affected by cyber sickness symptoms directly after the experiment. For IMI, 3 categories were chosen which were measured: interest/enjoyment, perceived competence, and effort/impotance. People could rate statements on a scale from 1 to 7, where 1 is not true at all, and 7 is very true, with 4 being neutral. The other questions that were added were related to the multiplayer aspect of the game and if it is suitable for learning, and used the same scale from 1 to 7. The results indicated the following: No cyber sickness symptoms: all the scores for cyber sickness symptoms lie between 1 (none) and 2 (slight). No mean score actually reaches 2, out of which it can be concluded that cyber sickness does not appear with this game. High IMI scores: very high interest/enjoyment, slightly lower effort/importance, but still considerably high. Perceived competence not so high, but that is not seen as a problem. The game should not be too easy/too difficult, because that may cause boredom or an unsatisfying feeling of incompetence. Suitable for learning: overall people indicated that the skiing game is suitable for learning. However, only the least experienced group think they can actually increase their skiing skills with it. This might be due to the low pace at which the game was played. Fellow player is motivating: unfortunately, only 8 out of 17 participants of the 1st test round were presented to the multiplayer version of the game, due to the bad quality of the internet connection at the location of the experiments. Out of these 8 people, only 5 noticed the fellow player. However, those 5 people indicated that the fellow player motivated them and that they liked it. Preference of last version: every participant of the 2nd round of user tests indicated that they preferred the last version of the game over the first version. All of them indicated that the last version made them more aware of the things they did wrong in the game, which can be interpreted as that the last version of the game provided better feedback. However, these persons might have been biased since they also participated in the 1st round.

- Finally, the learning aspect of the game was evaluated very positively. The test participants indicated that they think that the skiing game is a useful tool for learning how to ski. The test participants who were moderately experienced at skiing also indicated that playing the game more regularly would help them increase their own skiing skills. The other two groups of test participants, the experienced skiers and the very experienced skiers, said that they did not think they can learn anything from the game. Some of them indicated that this was mainly due to the low pace that the game is being played at and that they might be able to increase their skiing skills by playing the game if the speed of the game would be increased. Again, these results do not have any statistical relevance since they are generated by a group of seventeen test participants.
- Probably Ergometer is for short-term lowest possible split test your rowing technique, one can improve the ergometer by combining the ergometer with a rowing boat, so that the technique which is used on the water, can also be applied on the ergometer. One of the interviewees mentioned another advantage of an ergometer training compared to a rowing boat training: “An advantage is that the coach is very close to you, and thus he can see the little things more easily” coach wants to test your rowing technique, one can improve the ergometer by combining the ergometer with a rowing boat
