Not quite the first such product, Microsoft's original "Surface" advertised similar boardgame potential. But if it worked well, I don't know of anyone who was rich enough to try it!
Hopefully the technology has matured since then.

Detection technology on Board is much more robust. The MS Surface FTIR approach was lovely, but so over-featured no one could imagine a scoped-down (ie. cheaper) version of it.
It behaved very similar to the Board. It definitely had a "knob" that you placed on a screen could spin to make adjustments.
