A mind-reading chip that lets you control a computer by just thinking has been made public at a conference in China. Named Brain Talker, the chip could be used to control computers, smart phones and other devices, its creators say. It has been jointly developed by Tianjin University and China Electronics Corporation.

This kind of brain-computer interface (接口) is designed to let a person control a computer, a smartphone or other electronic devices using his/her brainwaves alone-without needing any forms of verbal orders, movements, or button pressing. Brain interfaces would not only allow for the faster operation of various technologies, but also be used to assist people with disabilities, for example by letting an individual drive an electric wheelchair just by thinking.

“Brain-computer interfaces hold a promising future,” said Dong Ming. "The Brain Talker chip advances brain-computer interface technology, allowing it to become more portable, wearable and accessible to the general public.

The brain decoding (解码) chip works by picking out minor neural (神经) electrical signals in the brain and rapidly translating them into a form that the computer can understand. “This brain-computer chip has the ability to identify minor neural electrical signals and decode their information efficiently, which can greatly enhance the speed and accuracy of brain-computer interfaces，” said Dr. Dong.

Recent technology advances have allowed researchers to develop the Brain Talker chip, so it is smaller and operates faster, more precisely and with greater efficiency than existing brain-computer interfaces. Although it is not clear exactly how the device will be worn, most brain-computer interface devices are worn on the outside of the body, rather than being fixed directly into the users’ brain. Cheng Longlong, a data scientist, said that the research team will attempt to improve the performance of the Brain Talker. One day brain-computer codec chips will contribute to medical treatment, education, self-discipline, security as well as games and entertainment.
