Development of small device for the brain computer interface with transient VEP analysis

Recently, the input interfaces for the PC using the EEG have been studied. The visual evoked potential (VEP) caused by the blinking light is one of waveforms observed in the EEG signal. The brain computer interfaces which based on the transient VEP (TRVEP) analysis and realized the four choices also have been studied. However, now we have been using a large amplifier and AD board. Furthermore, these two devices are expensive. In this study, in order to solve this problem we developed a small and inexpensive device. In addition, we performed comparative experiments of the conventional device and performance.
