New: this project is also covered on d-touch.org.
In tangible interfaces physical objects are used for the control and representation of digital information. Where in a graphical user interface users interact with virtual objects represented on a screen trough mice and keyboard, in a tangible interface users physically place and move objects in the real space to achieve the same results.
My interest is in developing tangible interfaces that can be deployed in school and domestic environments. Focus is therefore on low cost technology and mapping strategies that are intuitive but flexible enough to be scalable.
