I intend to describe something possible to be held by hand.
I want to use the word in this fragment:
Flat 3-dimensions and grabbable 2-dimensions.
I'm trying to express in my paper that the dimension seems to be reversed because of the dominance of smartphones. Basically, a plane cannot be held by our hand. But because we have become so familiar with LCD monitors - even more than external reality - I think we understand virtual reality as 'flat 3-dimension' and reality as 'grabbable plane'.
I've found words like 'holdable', 'grippable', 'grabbable' and 'graspable' but I'm not sure which one would be best.
