BCI (Brain Computer Interface) is a system that controls machines and devices by extracting neural information from human brain activity and inputting it to machines. BCI system can be used to feedback the brain activity level to users so that they can control their brain activity, which is called NFB (Neurofeedback). The NFB system is expected to make better condition for ASD (Autistic spectrum disorder) and ADHD (Attention deficit hyperactivity disorder) patients. The NIRS-NFB system measures the brain activity by using portable NIRS. The measured brain activity can be inputted to various machines and devices (display monitor, toy car and video game). To evaluate the effectiveness of the developed system, we conducted experiments of NFB training for ASD participants. It is shown that more brain activity can be observed after the NFB training for ASD participants. Those results show that the developed system is effective in the NFB training for ASD participants.
