This application is an augmented reality environment which simulates a concert, developed for the Virtual and Augmented Reality course held for the Master in Innovation and Research in Informatics by Prof. Pelechano, Prof. Andujar and Prof. Fairen at Universitat Politècnica de Catalunya in the academic year 2021/2022.

The application was developed using Unity 2020.3 and Vuforia.

The registration of the environment is done via markers (stored in a custom Vuforia database). For this application, three diferent markers have been designed:

• One marker for the musician
• One marker for its instrument
• One marker for the music repairwoman.

The world reference system is defined by the device.

• The player can bring an instrument to the musician using two different interaction methods, either by dragging or moving the marker, and he will start playing.
• A bar indicates the health of the instrument, which decays over time.
• When the health of the instrument drops to zero, the musician stops playing and the instrument has to be repaired.
• A broken instrument glows red.
• The instrument can be repaired by bringing it to the repairwoman, that will approach the instrument when it is close enough and repair it.
• The repairwoman will then move back to her marker and the instrument can be brought back to the musician.
• The UI can also interact with the objects in the real world: by clicking on a flag, it is possible to move it around the musician.
• The flag cubes can be scaled with a pinch interaction, and the biggest one will glow green and determine the song being played.
