Augented Reality and urban change
An Augmented Reality (AR) exhibit was designed by CASA and Polly Hudson Design for the 2013 English Heritage exhibition ' Almost Lost'. It explored the potential value of physical models and AR to communicate the complex history of areas, and to stimulate debate around the retention, adaptation and demolition of stock.
A wooden model of Woburn and Torrington Squares in Bloomsbury in 1840 was built by hand, incorporating detailed lasar cut facades, by Billy Dickinson of Central St Martin’s modelmaking department. (Click here for more information). The model was based on photographs supplied by English Heritage Archives and on historical and contemporary maps. It was commissioned by Andrew Byrne of the London 1840 project as a sample for a much larger model of Georgian London.
An AR app was built by Kostas Cheliotis, Daniel Lam, Balamurugan Soundararaj at CASA allowing the team to explore the use of AR on 3D surfaces . The app incorporated three layers of data which georeferenced to the model when a tablet was scanned across it. The first contained wartime RAF imagery from English Heritage Archives, providing an aerial view of the area with the Georgian layout intact. The second contained the 3D photorealistic Blom model, allowing visitors to view the 1960s/70s buildings which replaced demolished
Georgian stock. The third layer, produced by CASA. enabled the viewer to see people and carriages moving down the model’s streets and smoke billowing from the buildings' chimneys. A film of the app in use is shown above.
