Vita 'AR Hockey' works without cards

All right, so the existing Vita AR games aren't hits. But Sony's still trying, demonstrating a new AR game at GDC that's more impressive than the current lineup. It's Pong.

AR Hockey, which the Sony staff assured me was currently only a tech demo, is an air hockey game in which two players face off over a rectangular surface, each controlling their paddle by physically shifting left or right.

Unlike, say, Table Soccer, which uses six damn cards, AR Hockey can build a playing field out of any rectangular surface it detects -- basically, any corners the Vita can see. This is the "markerless" AR tech shown by Sony back at TGS, and it seems to work just fine, even if you move the Vita around to change your perspective on the game. Though, as one nearby attendee asked, "Why would you want to do that?"
