Review of building information encoded in construction documents is time consuming and cognitively challenging. The increasing use of computers for communications and building information modeling (BIM) means more and more information will be available digitally, but may not be explicitly included in the editing environment. A new over-the-shoulder multi-user interface paradigm, combining aspects of Tangible User Interfaces (TUIs) and Augmented Reality (AR) was developed in a prototype proof-of-concept application called CAPRI (Context Aware Paper-based Review Instrument). This paper reports on the rationale and development of the CAPRI system.
