Rather than a ball in a tube, those using the MindWave actually manipulate apps, and there are already more than 30 apps and games for the system at NeuroSky’s online store. One, Speed Math, measures a student’s ability to focus while he is learning.
Other apps for the MindWave encourage students to meditate or relax. And in doing so, they are able to change the outcome of games. One of the apps even allows users to change the outcome of a movie by adjusting your mental state.
The MindWave kit (store.neurosky.com/products/mindwave-1) costs about $100.
