In the game, a sneaky virtual robot aims to predict a playerâs intentions to act based on their action history, muscle activity, or brain activity.
The game can be used to assess: 1. the accuracy of brain-based movement predictions, 2. the timing of these predictions relative to movement onset, 3. the potential benefit of brain-based over behavior-based predictions, and 4. the correlation between certain brain signals (e.g. the readiness potential and event-related desynchronization between 8-30Hz over the pre- and primary motor areas) and the experience of an intention to move.
Answering each of these questions may greatly benefit future applications in prosthetics and motor rehabilitation.
Flip-that-Bucket is made as an extension to the open-source buffer_bci toolbox, encouraging further development.
