AN EEG MOBILE DEVICE AS A GAME CONTROLLER

Abstract

In this work the real-time control of computer games was explored by a single electrode mobile electroencephalography (EEG) device with a Bluetooth interface. The amplitude variation in the two frequency bands of 4-12 Hz and 60-200 Hz was selected as the real-time control parameter. The frequency-domain of a raw EEG signal was calculated using the discrete Fourier transform. The time-dependent signal samples equal to 512, 1024, and 2048 time points in size were used in our research. The well-known classic Pong game was used to try out our controller. The developed software handles communication with the device and real-time game rendering. The .NET Framework with the C# programming language was used as a development tool. 50 gameplay trials were made for each controller setup. The obtained results are promising for the possible use of the device in real-time communication with computer devices for people with hand disabilities.
