Virtual Environments (VE) influence design processes increasingly. We investigate the outcome of creation, interpretation and communication of architectural design, by using a three-dimensional (3D) maze together with text-based communication in a series of collaborative design experiments. The goal of our study was to identify how designers use and communicate design ideas by using VEs versa conventional methods of two-dimensional representations such as paper and pen. We developed a 3D-maze tool and set-up a series of experiments, including navigation- and perception-challenges, transcription of design, remote communication between design partners and controlled observations. We discuss how architects collaborate with partners and communicate their proposals in VE compared to actions in paper environments.
