1 AR in architectural and urban planning. søren s. sørensen, architect / assistant professor the oslo school of architecture and design, norway.

2 AHO aho is an independent higher education institution within the Norwegian university system and one of the leading schools and research centres in the fields of architecture and urbanism in Scandinavia.

3 Architectural practice Urban planning and the design of large scale architectural projects today utilise traditional techniques as projections, perspectives, 2D data and 3D physical and digital models. These embody both the need for abstraction and interpretation and thus the subject matter is difficult to understand and can mislead those not trained in the field.

4 prevailing view on representation:...the notion or understanding that value-neutral representations as plan, section and details collectively constitutes the total idea...

5 Current representation of the man-made environment: Two dimensional: plans, sections, elevations Three dimensional: sketches, perspectives, models, virtual reality. The limitation of these types of representations is that viewers are always positioned outside the representation, they remain spectators rather than participants.

8 - one still has the problem of understanding space and the scale of proposed projects. interactive digital models can give a solution to this...

9 Sensorama Simulator, US Patent #3,050,870, : I. Sutherland's doctoral theses: Sketchpad. stereo HMD/ position tracking/ graphics engine. 1966: T. Furness: display systems for pilots 1967: Brooks: GROPE force feedback system 1977: Sandin and Sayre: bendsensing glove 1979: Raab et al: Polhemus tracking system 1989: Jaron Lanier coins the term virtual reality 1994: VR Society formed etc

10 In a VR model all parts of a scene has to be digitally constructed, which requires extensive work for the making of the model and highly specified and expensive hardware for the regeneration of them. Orientation in a VR model is not intuitive, the feeling of presence is hard to achieve and the problem of scale is still not solved in screen based systems. That is, even though one moves through digital models that closely resembles a reality, it is experienced as a scale model on a screen. Advantage with VR-models is that they can be easily shared and distributed.

11 Augmented Reality is a further development of the technology and is understood as a combination of digital models and the physical world. An AR system generates a composite view with a combination of a virtual model or scene and the physical, real life setting in which the viewer is located. The technology has until recently been expensive, resource demanding and requiring advanced knowledge in the field. Due to these factors the use has been limited mainly to military use, medical research and other highly specialised applications

14 examples on research on AR in urban planning:

15 example 1: Augmented Urban Planning Workbench: Overlaying Drawings, Physical Models and Digital Simulation Tangible Media Group, MIT Media Laboratory Department of Urban Studies and Planning/Department of Architecture, MIT School of Architecture and Planning IEEE & ACM ISMAR 2002 to solve the: "problem in the spatial and temporal separation between the varying forms of representation used in urban design"... they " propose an Augmented Reality Workbench... that attempts to address this issue by integrating multiple forms of physical and digital representations. 2D drawings, 3D physical models, and digital simulation are overlaid into a single information space in order to support the urban design process."

16 example 2: INTERACT 03 ARTHUR: A Collaborative Augmented Environment for Architectural Design and Urban Planning Fraunhofer Institute for Applied Information Technology, Germany The Bartlett, University College London, Linie 4 Architekten, Germany Human-Computer Interaction.."real collaborative approach to architectural design and urban planning is often limited to early paper-based sketches. In order to overcome these limitations, we designed... the ARTHUR system, an Augmented Reality enhanced round table to support complex design and planning decisions for architects.... our approach does not try to replace the use of CAD systems but rather integrates them seamlessly into the collaborative AR environment."

17 aho and ife

18 aho and ife - AHO and IFE has a strategic agreement on cooperation. - common areas of interest between the two institutions regarding the use of virtual- and augmented reality in planning processes. - completed one preliminary VR project funded by the Norwegian Research Council; designing for the disabled: The use of Virtual Reality in planning.

19 aho and ife AR projects: (syn)aesthetics; Diplomaproject by architectural student Halvor Høgset. church of St. Margareta; reconstruction of a mediaeval church north of oslo by means of augmented reality. ongoing development of research on the use of AR in architecture and planning of the built environment.

23 ar-lab, norway contributions: ife has developed augmented reality software and systems for use in the atomic energy and oil industries. aho has developed expertise in the area of visual representation applied to the built environment.

24 - AR has the potential of helping us to manage change in the man-made environment by improving the way in which we represent proposed architectural and urban change -
