Update: Completely false rumor.
My colleague, Jacquelyn Erdman, writing on her website, Technolust & Loathing:
In Oct 2010, at the ACM SIGCHI conference in NYC, grad students presented on this technology and allowed people to demo it. See my conference notes at: http://technolustandloathing.wordpress.com/2010/10/15/acm-uist-notes-4-next-generation-touch-screens. They students mentioned that “someone” bought the rights to the technology, but wouldn’t say who. I then saw a very tiny blurb about Apple having the technology in the ACM Communications magazine several months back. I actually thought they would have this up and running for the iPad 3, (see prediction here), but I wasn’t sure how quickly it would roll out as I thought the iPad 3 was going to be out for last holiday season. So, enough of my rolling of the eyes on the release and self-congratulations and let’s talk about the technology! Jacquelyn goes on to describe what it was like to use it, and speculates on how Apple has probably improved it since then (if this all turns out to be true). She wrote this piece shortly after I shared the news from Apple Insider this morning about Apple using technology in the new iPad to be announced today from a company called Senseg. This could be huge.
Update: Apple patented this tech in 2010.
