MindPlay was a technology designed to monitor blackjack players' actions while playing in a casino, first released in 2003 and discontinued in 2007. Monitoring a person's play traditionally is done visually, by the dealer, floorperson, pitboss, and the ''eye in the sky'' (video surveillance). If one of these observers notices something unusual in a person's play, they will do what they can to either # determine if the person is a cheat or a card counter, or # change the game to turn the odds back in favor of the casino, through more frequent card-shuffling or other methods, or # casino personnel may bar a player they think is a card counter, even though the practice is legal. ==Operation== MindPlay utilizes a specially-designed blackjack tabletop that incorporates many features to monitor players' actions: * Specially encoded playing cards, using invisible ink and barcodes, see card marking. * 14 tiny cameras built into the dealer's chip tray (which is now slightly elevated to account for the cameras). These cameras can read every card in play by reading the invisible ink printed on them. * Special chips, so that sensors embedded in the table can automatically calculate each player's bet more accurately than a dealer or pitboss could visually. As MindPlay monitors every card that has been played along with players' betting habits, it is also counting cards just as a card counter would do while sitting at the table. If MindPlay notices that bets are changing dramatically at the same time that a card counter would typically make those bets, MindPlay will notify casino officials that they may want to investigate further. MindPlay tables cost around 20,000 USD. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MindPlay」の詳細全文を読む スポンサード リンク
