Developing an Augmented Reality (AR) application is usually a long and non-intuitive task. Few methodologies address this problem and tools implementing these are limited or non-existent. To date there is no efficient and easy development tool tailored to the needs of Mixed Reality (MR). We are presenting an initial taxonomy of MR applications, add...

We are presenting a software development framework called OSGART for Rapid Application Developement (RAD) in the domain of Mixed Reality (MR). This toolkit is being developed as an extension to OpenSceneGraph [3]. It implements a hierarchical, scenegraph based approach to marker based AR using the AR Toolkit [4]. Due to its’ tight integration with...

Traditionally urban design is perceived, communicated and created using physical and digital media. However, these realms are handled as separate entities, which hinder collaboration, understanding and communication. Collaborative Augmented Reality (AR) systems can integrate these tasks into one media type and allow a different conversation with co...

Sensorial richness is essential in the design process, yet digital design tools do not respond to this need. Tangible interfaces offer an opportunity for interaction with design computing systems to explore means of supporting a wider range of experiences. In this paper we look at implementations of tangible interfaces through a framework based on...

Ten years after Nielsen wrote about the “next generation interface” [1] we are still largely confined to WIMP [2] interfaces in design computing.

The problems of inspecting urban design proposals are different to that of architecture. The larger context is a crucial aspect in urban design. Generally the issues are not of detailed design but rather understanding space and spatial features. Discussions about proposals use plans and large urban design models. The models are cumbersome and acces...

Design technology simulates a variety of senses but on the other hand restricts them to audio and visual responses. What happens if technology can accommodate more senses in the creation process and how does it affect the way we approach design? This paper investigates the implication of tangible interfaces in design computing. The focal point is t...

The sketch is the embodiment of the architectural discussion. It incorporates rapidness and fuzziness and as this it is an object of interpretation. The interesting thing there is the question, if the usage of VR/AR already in the early phases of a design can have an impact for the quality of a design-process. Examples like VRAM (Regenbrecht et al....
