The sensor is said to have already been gone through a test run, which went pretty well. During the test, the tester had to concentrate on different actions, for example they had the aim to breathe continuously on the same frequency, or they also had to try singing a song inside their head. The error rate during this test was very low. In more than 99% of all cases the sensor worked flawlessly. Several sensors are usually used for those test, but in this case, only this one sensor on the headset was sufficient.
According to phys.org, it is possible to identify user through thoughts with the help of a headset, which does not cost too much - this might not be in the near future anymore, but becomes reality.
