Different sports require accuracy when throwing a ball (i.e. basketball, baseball, American football), but we only rely in our judgement to guide us or correct us when doing these tasks. As we are humans, these judgements are based on imprecise information that disappear immediately from our minds, but technology can help us by showing interactive guides based on exact calculations. This project created a prototype using Virtual Reality and Motion Capture to achieve this goal, and it was evaluated by 11 users. This helped us determine that the tool has potential to be a valid solution since the users did not feel high discomfort and they considered the guides useful. But improvements need to be done in the way the feedback of the performance is provided, and in the view by making it in Augmented Reality.
