The goal is to design and kick off a general system adaptive environment for users to experience to improve mental health. All to be used in a VR context. The concept entails what they call, an Emotional Labyrinth, a 3D maze procedural generated by the users decisions, with its look and features changing in accordance to the users emotional state

The maze above differs in size with difficulty. The user is hooked up to a real time Affective State Estimation module and monitored(Bermudez I Badia). Upon emotional state change the maze will display different images.
The results concluded that it was a positive experience and was quite healing.
