MindPlay works by placing a set of 14 digital cameras around a specially built blackjack table tray. The optical equipment registers every card in play by reading special invisible ink printed on them.
But that isn't the only trick up MindPlay's sleeve. It can recognize the differences between a player's drink, a napkin, an ashtray, a stack of chips being held by a player and a pile of chips in play, Soltys said. And it tracks the location and value of chips by comparing 3-D models of them in a database to all objects on the table.
It will be interesting to see where that will go.
