iOS 5 Sensor Programming: Augmented Reality and Location Embedded iPhone and iPad Apps

Although developers have covered a lot of topics and activities with more than 725,000 apps for iOS devices, they have yet to tap the riches of location-based and augmented reality applications. This book shows you how to use iPhone's sensors – the three-axis accelerometer, GPS, digital compass, and camera – to build cutting-edge location-aware apps that interact with the physical world. You can easily access iPhone's sensors, but interpreting the data you get back from them is tricky. Harder still is combining the input from several sensors with outside data sets.
