i took "touchable" to mean you could literally feel the shape with your senses, but it appears what they are saying is it's a way to interact with it, via pass through in various ways, etc. still pretty cool though
There are touchable graphics at the expo in Osaka. I think they‘re created by sonic waves and feel „fluffy“.
