Metaio is trying to make all physical objects touchable by recognizing (in future via HMDs) emitted heat of the human finger(s). So we can link every object with digital information or services. Unfortunately yet the idea needs a lot of work to be done.
Would be interesting to see if the concept operates as aspected with warm/hot objects when I, let’s say, want to play chess on a sun-exposed table in front of a coffee shop.
