T-Room springs from a pressing need to provide children with ASD and their families with an alternative for traditional assessment and, at the same time, it was used with the therapeutic training environment. For this goal we have used a Virtual Immersive Environment as a place to carry out non-intrusive a methodology that allows us to validate therapies based on implicit stimuli. We have researched in physiological measures for earlier and more effective detection. This project has been funded by CDti with project number IDI-20170912.
