The mind-reading device was taught to guess the intended number
Scientists have achieved encouraging success in direct communications between the brain and the computer. For the last time they managed with the help of the brain to operate a quadroopter , wheelchair and play video games. Now researchers from the Japanese university Toyohashi reached new horizons with a technology that is able to recognize individual words and even guess numbers to within 90%.
Technology scans brain waves with a cap for electroencephalograms. It is a set of electrodes that record electrical signals from the brain.
The main problem with previous developments was the limited amount of data that they could collect. A new approach to interpreting signals based on machine learning and holistic pattern recognition made it possible to achieve much higher performance.
Now the system copes with the recognition of a number from 0 to 9. The accuracy is an impressive 90%. Moreover, the machine can even guess words in Japanese from a small list with 61 percent accuracy.
Japanese scientists hope that one day their achievement will allow people who have problems with speech to speak. And perhaps it will be the basis for new revolutionary interfaces between human and computer.
