its too small to work for TTRPGs at the moment but if we could get the capacitive pattern tech and expand that to work on digitiser layer on a tv sized screen, i would be really cool.
It depends on the size of your table, of course. The area looks no bigger than game's i've played that use a battlemap or like a little miniature scene with dungeon tiles. Bigger is certainly better as we age or if the physical table you play on is huge though.
