Facebook launched the research shop, called Building 8, last year to conduct long-term work that might lead to hardware products. In charge of the unit is Regina Dugan, who led a similar group at Alphabet Inc's Google and was previously director of the US Defense Department's Defense Advanced Research Projects Agency, or DARPA.

Dugan told software developers at Facebook's annual F8 conference that the company was modeling Building 8 after DARPA, a government office founded in the 1950s that gave the world the internet and the miniaturized GPS receivers used in consumer devices.

Any hardware rollouts are years away, Dugan said in a speech. Potential products could, if successful, be a way for Facebook to diversify beyond its heavy reliance on advertising revenue.

One example of Building 8's work so far, Dugan said, was an attempt to improve technology that allows people to type words using their minds.

"It sounds impossible, but it's closer than you may realize," Dugan said.
