Описание: Over the last few yea rs the new generation of smart phones, such as Apple's iPhone, has finally sta rted to live up to their name and have become the primary interface device for geographically tagged data. However not only do these devices know where they are, they can tell you how they're being held, they are sufficiently powerful to overlay data layers on the camera view, and record and interpret audio data, and they can do all this in real time. These are not just smart phones, these are computers that just happen to be able to make phone calls.

This book should provide a solid introduction to using the hardware features in the iPhone, iPod touch, and iPad.
