A realtime brain-computer interface based on PDA

A system that uses the human ability to control a portable video game device through some electroencephalographic (EEG) rhythms has been presented. The neural signals obtained by EEG recording equipment are sent through a Web Service technology connection to a PC that processes it in real time and sends it wirelessly to a mobile gaming device. Web Service has been used as a wireless technology for sending EEG signals to a PC and vice versa, the PDA gets the command from the PC though the Web Service technology, which has been proposed and furthers it showing that the system is reliable and robust enough to work in BCI systems. In this study we have investigated the human´s ability to play a video game by manipulating neuronal motor cortex activity in the presence of a visual feedback environment. This paper presents one of these solutions, which control games by BCI based on motor imagery. This type of BCI solution is translating the motor imagery EEG into three control signals: left, right or transmutation. And then use it as an input device of a simple game player to realize the function of operating games.
