For this paper, we created a virtual underwater experience to research the extent to which a user feels present in such an environment, when hand movements are redirected to mimic water resistance, and how this would affect the experience of beThis paper explores the effectiveness of different trajectory implementations in improving accuracy and learnability when throwing objects in Virtual Reality (VR). An experiment was conducted in which participants were asked to throw a virtual object at a target that changed position. Data were logged and analyzed to determine the accuracy and learnability of the throws, as well as the effects of different trajectory implementations. The results showed that the trajectory implementations significantly improved the accuracy of the throws, with the “live trajectory” technique outperforming the “simple trajectory” and baseline models. Furthermore, “live trajectory” was especially effective when the distance to the target board was increased. These results suggest that trajectories can be used to improve the accuracy of throwing in VR and can inspire further studies to test the many options that VR offers. This research has the potential to help those that wish to transfer learning from VR to the real world, as it could provide insight into how to improve the accuracy and learnability of throwing objects in VR.ing underwater. This effect was implemented using a movement opposing drag force and a gradually readjusting recovery force. The effect was tested using a questionnaire integrated into the virtual environment, to prevent breaks in the sense of presence. The experimental results were inconclusive due to large variation in data, but suggested possible improvement in presence.
