1. The Build-It Story Prof. dr. Matthias Rauterberg Faculty Industrial Design TU/e Eindhoven University of Technology

2. © M. Rauterberg, TU/e The Digital Desk from Pierre Wellner in 1991 Pierre Wellner The DigitalDesk is built around an ordinary physical desk and can be used as such, but it has extra capabilities. A video camera is mounted above the desk, pointing down at the work surface. This camera's output is fed through a system that can detect where the user is pointing (using an LED-tipped pen) and it can recognise the documents that are placed on it. The more advanced version also has a computer-driven projector mounted above the desk enabling electronic objects to be projected onto real paper documents -- removing the burden of having to switch attention between screen and paper and allowing additional user-interaction techniques.

Designed for individuals who demand mobility, this computer offers voice control and heads up display for complete, hands-free operation. Users can enter or retrieve information while going about their jobs, instead of constantly returning to the shop area to check a stationary computer, or stopping work to punch keys.

Rauterberg, TU/e Head-up Displays in Cars More information and less distraction Information on the state of the road, on the speed of the vehicle in front (supplied by the intelligent cruise control), on obstacles lying around the next bend in the road identified by the remote detection system, or direction arrows sent by the driver guidance system... drivers will be receiving more and more information from "intelligent" vehicle systems.
