Immersive Bar

How might we create a joyful mixed reality experience which offers a recurring element of surprise? This question led Aditi, Laurin and Minatsu to develop Immersive Bar, a cocktail mixing game.

In this interactive game, the player chooses from three ingredients, represented by SenseHAT equipped Raspberry Pi boards, and pours them into a cocktail shaker. The ingredients are unknown, but by trial and error it is possible to find out what they are. In addition, the colors of the Sense HATs give a further indication of what the ingredients are.

While pouring the ingredients, an LED strip controlled by a fourth Raspberry Pi in the shaker visualizes the liquid level. Once the shaker is full, a computer running Unity mixes the cocktail and “drinks” it before giving a rating. The whole setup is recorded by a camera and displayed on a screen, enriched with a digital visualization of the liquid level, particles that show up while pouring the ingredients, and instructions.

In total, seven different drinks can be mixed, from pure Vodka to exotic cocktails such as the Astronaut. The rating is based on two factors:

  • The combination of the ingredients: while some of them complement each other very well, others lead to a nauseous creation.
  • The balance of the ingredients: is the ratio between alcoholic and non-alcoholic ingredients well balanced?
