Yiu pulled out a pair of Meta's recently launched Ray-Ban branded glasses, which use AI to translate speech from one language to another or describe images for the visually impaired.
"This is a profound and very human application of the technology, and it is slow to arrive in Europe because of the issues that we have around regulation," Yiu said.
Meta only began rolling out AI features for its Ray-Ban Meta glasses in some European countries in November, after a delay the firm claimed was caused by the need to reach compliance with Europe's "complex regulatory system."
