Pretty much every iOS game is played with fingers, but the (i)Pawn app from French studio Volumnique is trying to change that by employing a set of physical token that are each capable of being uniquely identified by the iPhone’s touchscreen. Click through for a video.
It’s a neat demonstration, but I’ll be honest with you: I’m not entirely sure how it works. Looking at the site, each token appears to be glued onto a different sized cell battery. Since the iPhone’s capacitive touchscreen works by using a layer of capacitive material to hold an electrical charge, and senses a touch when the amount of charge under your finger changes. If the bottom-loaded batteries on the tokens predictably change the amount of charge sensed by the touchscreen, this could conceivably work… but I’m not sure the iPhone’s touch software is that nuanced. Any developers out there who might be able to hand us their theories?
Either way, it’s a neat demonstration, an even if (i)Pawn looks like a pretty boring game, it could have some neat practical merits. The iPad’s a great size for a game board, after all: a Monopoly app with mail-away top hats, locomotives, irons and terrier tokens could be a pretty satisfying experience.
