maximal acceleration of UIAccelerometer

Question

i want to track how fast my iPhone is moved.

i checked the AceelerometerGraph Example App, where the maximum Amount was about 2.0 (in this app)

i want to know how exactly i can track the speed of my moving iphone. in this example app the maximum amount is reached very fast. Is there a way to get better results ?

Sry for my bad english :( Comment me if you dont know exactly what i mean

Answer 1

I don't know what your question is. The subject doesn't really fit the rest of your "question". It is impossible to detect speed with an accelerometer. You can only measure acceleration. I heard the maximum acceleration that can be detected with the iPhone's accelerometer is approximately 2.5g, but I'm not sure.

Answer 2

Yeah, it's about 2.5G... Unfortunate, I really wanted to build the iphone version of E39. Oh well.
