iOS Sensor Programming

Use iPhone's onboard sensors to build cutting-edge location-based and augmented reality apps. With this book, you'll learn how to combine input from the three-axis accelerometer, GPS, digital compass, and camera with outside data sets to create apps that interact with the physical world.

Although developers have covered a lot of topics and activities with nearly 200,000 apps for the iPhone, 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. This book shows you how to put it all together. It's ideal for experienced iPhone programmers, game programmers, augmented reality programmers, and geo hackers. * Get an introduction to the hot topic of programming iPhone's built-in sensors * Learn how to create sensor-aware apps that respond to a user's location * Understand the basics of augmented reality programming * Build apps that combine data from the accelerometer, GPS, digital compass, and camera
