Physical hypermedia: augmenting physical material with hypermedia structures.

The article provides an insight to the notion of physical hypermedia. The "Augmented Reality" research area focuses on linking digital information to physical objects, places, and spaces. AR aims at bringing information technology capabilities out of the traditional computer and embodying them in the physical environment in which people work and live. Hypermedia research focuses on supporting organization of information through concepts like links, composites, hierarchies and groupings. Studies of the work practice of architects have revealed a plethora of diverging material organization demands. Organizing material and information is related to a whole host of different concerns that closely intertwine natural, material, and social concerns. A special kind of annotation often made by architects and designers are layered sketches. Architects often use transparent tracing paper to draw on top of previously produced drawings and sketches. Studying organization and management of physical material and information sets focus on a range of methods, and subsequently on the artifacts used for supporting this process.
