A German research scientist has built an application that allows an i-phone user to digitally alter the appearance of a façade. Users simply aim their device at the building causing the viewfinder to show the façade on-screen which the user can then paint in different colours. This is then replicated on the actual building.
The 2nd video shows a similar approach using a higher definition OOH screen as a virtual blackboard which replicates what’s drawn on the i-phone screen.
