Nintendo is apparently trying to knock Apple from its market by including a tilt sensor in its new DS.

Apple has been pushing into Nintendo's domain by pushing its iPhone as a games machine. Now a developer who claims he's laid hands on one of Nintendo's super-secret 'DS2' development kits said that it looks like the Wii maker is set to strike back.

According to CVG, the new machine has a 'tilt' function that's not dissimilar to iPhone, but does a lot more. The iPhone uses a basic accelerometer that's capable of tilt-sensing but little else.

This means that Nintendo's DS2 could add shock and vibration detection. Maybe there is a pedometer for sports related activities. Add in a bit of image stability to let you snap crisper pictures, Gesture or tap recognition higher-fidelity controls in racing or flying games, dual accelerometers and you could be onto a winner.
