Scalebridge VR: Immersive Proportional Reasoning Game for Children with Brain-Computer Interface for Difficulty Scaling

We present the design and evaluation of Scalebridge VR, an immersive educational game that teaches children the mathematical skill of proportional reasoning. The game uses brain-computer-interface-based adaptive level difficulty to modulate difficulty of the game based on the player’s attention and meditation state. The game is an adaptation of previously introduced Scalebridge game that did not use virtual reality, but was shown to be an effective tool for learning proportional reasoning.
