Dr. Michael Tangermann from the Berlin Institute of Technology (Technische Universität Berlin) explain how the player can moves the chess pieces across a board by thinking only.
Out of the 64 electrodes in the cap, he activates 14 which measure brain activity in key areas which detects which piece the person intends to move. It’s an intricate task and the cap must be fitted precisely for accurate readings. As soon as the cap is fitted, a system calibrates the software in order to recognise the specific traits of the player’s brain activity. The brain chess computer is just the tip of the iceberg and the technology could have serious medical implications, improving patients’ lives for the TOBI project is all about helping patients with severe motor neurone diseases communicate with the outside world.
This project was launched in November 2008 with the help of a European Union fund of thousands of dollars called TOBI - “Tools for Brain controlled interaction” and it costed.
