China-developed interface makes thought-controlled typing a reality.

ISLAMABAD -- Researchers in northern China's Tianjin have developed a brain-computer interface (BCI) that allows users to type words with their minds.

The device, independently developed by China, provides a direct communication channel between the human brain and the external world, according to a researcher with Tianjin University.

The cap can pick up electroencephalograph (EEC) signals and send them to the computer. Then, the brain patterns, which carry the user's intent, are decoded by an algorithm on the device. Eventually, the information is converted into instructions and triggers an action, People's Daily reported .

Using the BCI, a graduate student in Tianjin University...
