Tap pressure strength detection using accelerometer

Question

Yesterday, in the presentation about the new Garageband for iPad 2, Apple demoed an interesting feature: The detection of the tap pressure by using the accelerometer. (See t

Answer 1

Try it yourself with the AccelerometerGraph sample app. The device and the tabletop have finite stiffness, so you might see little blips in the graph.

ADDED:

If you compile Apple's AccelerometerGraph graph sample from source code yourself, you can turn up the gain on the vertical axis and see blips for smaller accelerations.
