Adaptive Training in Virtual Reality Through Dynamic Alien Motion Support

Serious games in virtual reality showed promising results when applied to medical therapy, both improving the motivation of the patients, and the outcomes of the training processes. This technology allows operators to have full control over the virtual environment, as well as over the virtual bodies of the users. An alien motion, i.e. an alteration of the simulation response to the actions of the users, can be introduced to provide them with false feedback about their performance without them being aware of it. These modifications can be adjusted to support them during the training by making them believe they are performing better than they are in the physical world. The goal of this project is to investigate in which extent the support influences the outcomes of a virtual training. In this work, we present a ball throwing virtual scenario in which users are assisted through alien motion. Our findings show that dynamically supporting people can have a positive impact on the outcomes.
