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 operation. "We are not talking about monitoring your random thoughts,"
assured Facebook's Regina Dugan. "You have many thoughts, and you choose to
share some of them. We're talking about monitoring those words. A silent speech
interface(界面) — one with all the speed and flexibility(灵活) 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 employed 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(高清) movies every second. The problem is that the best way we have to get information out into the world-speech can only send 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. Finally, we want to turn it into a wearable technology that can be produced in quantity. "
Technology is going to have to
get a lot more advanced before we can share a pure thought or feeling, but this
is a first step. Other ideas detailed at the company's developers conference in
San Jose included work to allow people to "hear" through skin. The system,
comparable to Braille, uses pressure points on the skin to pass information. "One
day, not so far away, it may be possible for me to think in Chinese, and you to
feel it instantly in Spanish," Ms Dugan said.
