Tremors felt as Nintendo DS2 force feedback rumours begin to rumble

It'll be a while before Nintendo actually confirms anything about the DS2 rumours, but by then we'll undoubtedly have the full story - we just won't know which bits to believe, is all.

The latest addition to the rumour roster comes from an update that's been made to a force feedback system patent Nintendo filed in 2005, pertaining to a dynamic rumble effect in a handheld console.

The DS saw a poorly executed rumble pack add-on that no one used, but this patent seems a lot more specific than that. It refers to more of a haptic feedback technology that could apply varying levels of physical sensation to either on-screen actions, or the use of peripherals.

For example, the patent (loosely) describes the use of a small vibration in response to a stylus touch, or a minor rumble effect when a small amount of damage is applied to a character in contrast to a bigger vibration when a large amount of damage is dealt.

In itself this isn't massively exciting, but it does point toward Nintendo refreshing its tech for a possible GDC or E3 announcement. Watch (or feel) this space.
