Guess tertiary education has gotten too expensive for some, which could be the reason why students studying pervasive computing and user interface engineering at the University Duisburg-Essen came up with the ‘Poker Surface’ as a way to hone their poker skills to win some money. We jest – this brilliant invention will merge the functionality of cellphones and a multi-touch surface, letting one play poker by directly interacting with objects on the table and by using a cellphone. The cellphone itself offers a tangible feeling of holding cards in your hands as well – best to get an anti-reflective display and privacy filter for your handset, and wearing contact lenses would bode your quest well, too.
