Abstract
The Tangible Viewpoints project explores how physical objects and augmented surfaces can be used as tangible embodiments of different character perspectives in a multiple point-of-view interactive narrative. These graspable surrogates provide a more direct mode of navigation to the story world, bringing us closer to bridging the gap between the separate realms of bits and atoms within the field of digital storytelling.
