At BrainBar Budapest 2018, OpenBCI demonstrated an application of the focus widget, harnessing Alpha and Beta brainwaves to direct a flying shark.
The Focus widget displays the visualized summation of Alpha and Beta waves, giving feedback on your focus. With concentration, you can keep the yellow lines in the range indicated by the narrow, vertical blue line, allowing you to control the path of the shark.
The Head Plot widget shows the concentration in the frontal cortex.
