aspect was his guiding light as he helped companies develop and introduce new technologies into the hands of consumers My Walks is a good example of an app Robert developed where he applied the ease-of-use principal to a GPS-based walking application This app only requires the user to tap a Start button to start the walk and the app will automatically detect the end of the user's walk should the user forget to tap the End button My Walks was featured in the Best Mobile Apps 2013 book by Jeremy J Warner and published by Portrait Health Publishing Inc Robert has also developed a version for

responds to changes on its three axes when the iPhone is tilted Under normal gravity, each of these values will be between -1 and +1 with a value of being the middle center point Moving the phone in a rapid motion will increase these values: +Y -Z -X +X +Z -Y The following table explains each of the method calls relating to the CMMotionManager class: CMMotionManager methods Description startGyroUpdates When this method is called, Core Motion kicks in and continuously updates the gyroData property of the CMMotionManager class with the latest measurement of activity startGyroUpdates ToQueue:withHandler Before calling this method, you need to ensure that you have set the update interval of the gyroUpdateInterval property When this method is called, it creates an NSOperationQueue event that queues the gyroscope event that then fires when the update interval has been reached, then calls the function and passes it the latest gyroscope data stopGyroUpdates This method turns off the Core Motion sensors and stops all updates of motion data It is a good idea to always stop gyro updates as this will save battery power 373 www.it-ebooks.info Exploring the MultiTouch Interface If you would like to find out more information about the CoreMotion class, you can refer to the Apple Developer documentation located on the link http://developer.apple.com/library/
