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.

This book is still in progress, but you can get going on this technology through our Rough Cuts edition, which lets you read the manuscript as it's being written, either online or via PDF.
Alasdair Allan is a senior research fellow in Astronomy at the University of Exeter, where he is building an autonomous, distributed peer-to-peer network of telescopes that reactively schedule observations of time-critical events. He also runs a small technology consulting business writing bespoke software and building open hardware, and is currently developing a series of iPhone applications to monitor and manage cloud-based services and distributed sensor networks.
