What really sets the iPhone apart from laptops and PCs is its use of onboard
sensors, including those that are location-enabled. This concise book takes
experienced iPhone and Mac developers on a detailed tour of iPhone and iPad
hardware by explaining how these sensors work, and what they're capable of
doing. With this book, you'll build sample applications for each sensor,
and learn hands-on how to take advantage of the data each sensor produces.
You'll gain valuable experience that you can immediately put to work inside
your own iOS applications for the iPhone, iPod touch, and iPad.

This book helps you focus on:

* Camera: learn how to take pictures and video, create video thumbnails,
customize video, and save media to the photo album
* Audio: use the media picker controller and access the iPod music library
in your own application, and enable your app to record and play sampled audio
* Accelerometer: write an application that uses this sensor to determine
device orientation
* Magnetometer: learn how this sensor verifies compass headings
* Core Motion: use this framework to receive motion data from both the
accelerometer and the vibrational gyroscope
