Scalebridge VR
Scalebridge VR is an educational game which adapts its difficulty based on the player’s attention and meditation state, while exercising the skill of proportional reasoning.
Summary
In collaboration with School of Health and Health Systems, University of Waterloo, using low-cost EEG Brain Computer Interface (BCI), this project aims at improving proportional reasoning of children. The game adapts the difficulty of the proportional reasoning, LEGO-balancing task based on the attention level of the player as provided by the BCI device.
In this project, we examine the use of low-cost brain computer interfaces and low-cost virtual reality headsets, to improve learning outcomes for children with Attention Deficit Hyperactivity Disorder who are learning the mathematical skill of proportional reasoning. An EEG attention/meditation readout is used to adapt the difficulty of each game level. This project is a collaboration of the Institute for IDEAS with George Washington University and the University of Waterloo. To date, the results have been disseminated into two conference papers and as an educational VR game. This project’s main area of focus is improve health and addresses social equity. This project benefits from, and contributes to, data science and analytics in the area of processing EEG signal from brain-computer interface.
In this work, students presented the version of the game programmed for virtual reality. After a tutorial, they asked players to evaluate the game based on mechanics, freehand spatial input, and the gameplay itself. We used the collected feedback to improve the game’s implementation. In general, players enjoy the VR version and experienced no difficulties in grabbing, positioning, and releasing the blocks. We concluded that the non-VR Scalebridge is an effective tool for teaching proportional reasoning.
