CogniGame is a reinterpretation of a well-known video game from the 1970s. However, the action now takes place on a real playing field: with two players, a ball and two clubs, each mounted on a linear axis along the baseline. The club can be driven along the line to the left or right to fend off the sphere and keep it in play. One player moves his club with a joystick, the second controls his linear axis solely by thought power via the brain-computer interface (BCI).
As in electroencephalography (EEG), the brain-computer interface measures the voltage fluctuations on the surface of the head via electrodes mounted on the head. With the help of CogniWare software developed in-house, a connection between brain and hardware is established via the BCI without the user having to use speech or input devices. The software processes the signals from the brain computer interface and sends the command to the hardware, i.e. the clubs.
The BCI can be operated by measuring the so-called Mu rhythm. The Mu rhythm, a pattern of brain waves, is generated in the motor-sensory cortex and occurs with a physical movement or the mere idea of movement. So it is sufficient to imagine the movement of the left hand to get the axis to move to the left. A valve terminal with CPX terminal enables the exact control of both linear axes.
The brain-computer interface as the next generation of human-technology interfaces is also conceivable in industrial environments. With CogniGame we are therefore testing this new operating concept. Because the importance of human-machine interaction is also growing in production.
Despite the increasing complexity of the system concepts, the interfaces between user and hardware must become simpler and simpler. This calls for new operating concepts with which people can communicate faster, more directly and more simply with technology: from joystick solutions to voice input and perhaps in the future to the control of partial processes by thought.
