Facebook says it is working on technology to allow us to control computers directly with our brains.
It is developing “silent speech” software to allow people to type at a rate of 100 words per minute, it says.
The project, in its early stages, will require new technology to detect brainwaves without needing invasive surgery.
“We are not talking about decoding your random thoughts,” assured Facebook’s Regina Dugan.
“You have many thoughts, you choose to share some of them.
“We’re talking about decoding those words. A silent speech interface – one with all the speed and flexibility of voice.”
Ms Dugan is the company’s head of Building 8, the firm’s hardware research lab. The company said it intends to build both the hardware and software to achieve its goal, and has enlisted a team of more than 60 scientists and academics to work on the project.
On his Facebook page, Mark Zuckerberg added: “Our brains produce enough data to stream four HD movies every second.
“The problem is that the best way we have to get information out into the world – speech – can only transmit about the same amount of data as a 1980s modem.
“We’re working on a system that will let you type straight from your brain about five times faster than you can type on your phone today.
