uiaccelerometer

i have implemented following method in my application. - (void)accelerometer:(UIAccelerometer *)acel didAccelerate:(UIAcceleration *)aceler { if (fabsf(aceler.x) > 1.5 || fabsf(aceler.y) > 1.5 || fabsf(aceler.z) > 1.5 || fabsf(aceler.x) < -1.5 || fabsf(aceler.y) < -1.5 || fabsf(aceler.z) < -1.5 ) { self.navigationItem.rightBarButtonItem=nil; [self showImage:nil]; } } => I am eager to know " The range of aceler.x ". i.e. what would be the maximum value of aceler.x / y / z Same way the minimum ? ( I think, it should be zero ) Thanks in advance for helping me. A quick search shows that the iPhone

In my app I use the accelerometer to control the character in my game. Right now I only allow the portrait orientation so the user has to tilt the device to the right or left in order to move the character. That is working fine so far. What I am trying to accomplish now is to 'calibrate' the accelerometer to account for the current tilt the user is playing on. Lets say the user is laying on their side, the values will be skewed since it didn't account for that starting point so they won't be able to control the character. So I am trying to account for that initial tilt amount and then account

I want to count number of shake horizontally and vertically, I have referred to UIAcceleration I have also referred to Motion Events But couldn't come up with better approach. Any kind of help is highly appreciated , code , reference, or any type. i just want to count the number of shake user make by shaking the iphone device, the shake can be vertically or horizontally holding iphone in normal way(home key at the bottom) Try DiceShaker . You'll need to use the code for "Isolating Instantaneous Motion from Acceleration Data" given in Listing 4-6 of the motion events (also called high-pass
