There's a big problem with video games on Apple's iPod Touch and iPhone. There's no joystick to control them with, no directional pad to press. Just glass to touch and a device to tilt. At last, there's a strange solution.
Prepare to welcome to the world the two-directional virtual joystick, a virtual slider rendered on the bottom left corner of a major upcoming iPhone game, Ubisoft's Assassin's Creed II Discovery. It is used to move the game's hero, the Renaissance Italy assassin Ezio de Auditore through his 2D, side-scrolling world. Under the player's thumb, the slider "moves" left, "moves" right and ... that is all. (We recently previewed the game, slider and all.)
