The gyroscope and the Core Motion framework

A session at iOS Sensors and External Hardware Masterclass

Monday 8th October, 2012

11:15am to 12:30pm (GMT)

In addition to an accelerometer and a magnetometer the iPhone 4, and latest generation iPod touch and the iPad, also have a vibrational gyroscope. While an accelerometer provides measurement of forces in the X, Y and Z-axes it cannot measure rotations. On the other hand a gyroscope is a rate of change device, as the phone rotates around an axis it allows you to measure the change in such rotations. By using both sensors in combination you can measure the movement of the device in a six degrees-of-freedom inertial system, allowing you to use dead reckoning to find the physical location (and orientation of the device) relative to an initial starting position. During this session we'll look at the Core Motion framework and build sample apps using the gyroscope and Core Motion.
