On a 2m long green carpet, a pink dog guarding the goal, a white dog carrying football to the net. This would be nothing special if the behavior of the two dogs was not driven by two minded students through a brain computer interface system that experts from the Neuroscience Research Laboratory of Tsinghua University (China) has made successful research.

The system consists of an electrode cone, a brain wave transmitter and a computer data processor. According to Dr. Hong Ba, research team member, when people think, on the scalp there will be brain electrical activity that the scalp recorded is often called brain waves.

This type of brainwave wave is absorbed by the system and then filtered and classified automatically, judging the mind of man. Next, the computer analyzes the predicted state of thought into control commands and transmits it over the wireless network.

This type of system is currently being researched and applied in real life to help people with disabilities have poor mobility but brain normal can be through thinking directly control the wheelchair. , prosthetics and even typing, or can be applied in the fields of military, manufacturing and entertainment.

However, this system has limited speed, and when visual stimulation to a certain degree will increase the brain waves, so when entering the data will feel flickering flicker. In the future, it is possible to combine two brainwaves and news processors into a small box phone, with mass production costs of 2,000-3,000 yuan (4-6). VND million).

Currently in Germany and the United States also have a computer interface system, but the accuracy of the information processing system of the machine developed by Tsinghua University, according to Professor Hong Ba, "is the top. gender ". He said his research team has been conducting research in the field of psychiatric identification and treatment for nearly 20 years.
