The world disc

Research question

How can an cumulative and timeline based gestalt show a map of the history of the build environment in which the visitors’ activity is recorded as traces of connections between architectural typologies?


Architectural Biennale 2016 in Venice.  The setup consisted of three projectors displaying a seamless image onto a tryptic screen (total size: 3.60×6.0 m) The screen itself consisted of three canvases, each at an angle of 150◦ to each other. This CAVE-like installation—where also the user’s peripheral viewport was covered—allowed each visitor to “dive” into the shown environments and therefore enabled an immersive experience, and to create a bodily notion of that featured space. In parallel, the visitors were able to create their own spaces, as ‘ideal’, i.e. imagined environments based on archit. Parameters from the worlds presented in the cave: 


  • Ideal Spaces exhibition, explanation of the world disc 
  • Michael Johansson & Ulrich Gehmann: Ideal Spaces (book chapter). About our exhibition at the Venice Architectural Biennale 2016 Palazzo Mora, Venice Italy Springer Verlag 2018


  • Most frequent connections between arch. parameters /typologies
  • Based on visitor interaction, through visitors making their own worlds

Concept for 2016-exhibition Ideal Spaces (Biennale Venice): architectural typologies from the worlds shown as ideal spaces have been translated into types for interactive world-making, and the results of the latter got manifested in the world disc.
