Gyro instead of IR aiming confirmed in World of Goo

[Peh]

I just don't understand why anyone is still surprised by it? The controllers have a gyroscope sensor and an acceleration meter build in. Those two are more than enough to make a pointer on any screen work. You don't even have to point at the screen. Wii Sports Resorts and Skyword Sword could do that already on the Wii with the Motion Plus controls.

You don't need IR for it.
