He says Meta can turn “any flat surface” into a virtual keyboard capable of 120WPM speeds. That’s fast! Meta’s 2020 “PinchType” averaged just 12WPM, though the company’s “surface touch typing” averaged 73WPM that same year. I’m not seeing a research paper for today’s brag yet.

My question: does this work without the fiducial (QR-code like thingy on the table) as a frame of reference?
