It has an online average information transmission rate of over 300 bits/minute and an average single command output time of only 1.2 seconds, "the highest of its kind in the world", the team claimed.

The BCI technology refers to building a direct connection between the human brain and external devices to allow the brain to "talk" with machines.

It is a core type of technology for the new generation of human-machine interaction and human-machine mixed intelligence.

The technology is a major improvement from the third WIC in Tianjin in May 2019 where a volunteer wearing BCI devices "typed" a complete sentence, "Welcome to the 3rd WIC", on a screen without moving her fingers or thumbs.

The chip the volunteer used was the world's first BCI chip successfully developed by the university — the Brain Talker.
