Aura is a project designed to analyse and visualise the emotions of pre-adolescent long-stay patients at Sant Joan de Déu Hospital. Using facial recognition technology and a physical interface, the system records the frequency and intensity of four basic emotions: joy, sadness, fear and anger. Each emotion is represented by a specific colour: yellow, blue, red and green, respectively.

Based on this data, Aura creates an emotional map through LED lights, offering a clear and accessible representation of the patient's emotional state. This visualisation can help patients recognise how they are feeling while also supporting medical staff in understanding their emotional development.

The project also includes an exploratory video game that encourages users to discover and understand the main emotions and their different nuances. The experience is divided into four abstract worlds built through colours, shapes and sounds, with each world representing a basic emotion.

Throughout the journey, players encounter questions and situations that encourage reflection and introspection. In this way, Aura combines technology, interactive design and emotional learning to transform entertainment into a tool for self-awareness, communication and support within the hospital environment.
