In a talk this morning at the O’Reilly Media Tools of Change for Publishing conference in New York, Inkling CEO Matt MacInnis, showed off Inkling Habitat, the company’s new software for creating interactive books for the iPad.

The has an “object-oriented content structure” meaning that it has moved the idea of designing books from a page-based model to a software-based model.

The tool lets publishers make interactive content including guided tours, 3-D exhibits, interactive quizzes and  high -def video. And it functions more like web software in that all of the content can be published and even updated instantly.

Habitat is available to select partners now and will be available more broadly later this year.
