Sketching a set of desing principles <<<click me!!!
We are happy to announce our first physical prototype (aka. Rosie) within multi-touch technology.
Rosie is an interactive surface for multitouch interactions.
It was buildt with the intention to design applications and look for new ways of interaction.
Created by Andreas Göransson and Fernando Lbarrajón for Malmö university.
Fingers are seen as points of location, areas of contact. Based on these sensory inputs the interface tries to generate graphical widgets which behave along preconceived human notions of physical objects.
A projector, a camera and IR lighting are mounted behind a diffuser (aka projection surface). The camera picks up the infrared light reflected by objects behind the surface and a computer attached to the camera uses image processing to extract positional data from the images. In front of the projection surface, you can attach a transparent surface (we used hardened glass) to prevent damage to the projection surface itself.
