Toyota developed the best social application of brain signals processing to help the people who are bound to wheelchairs. The user of the wheelchair just need to think about the commands of left, right turns or forward motion. All is thanks to real time fast calculations of one line EEG signals. The brain waves of the person is analyzed every 125 milliseconds and the results are translated into real mechanic movements. An accuracy of 95% was achieved.
Expect to see commercialized brain controlled wheelchairs in not very far future.
