== MTT-Construction ==
In principle the Multitouch Table (MTT) consists in a box with the multi-touch screen mounted on top in the shape of a cube. For more extensive service work the touch screen can be simply removed from the top.
All parts for side walls were manufactured using 16mm 3-layer-laminated sheets of wood and for bottom was using 19mm 3-layer-laminated sheets to guarantee maximum stiffness of the corpus. The only exceptions are the square-shaped timber pieces which serve as support for the bottom- and touch screen glass plate.
Four 20 cm long square-shaped timber pieces were glued to the four corners inside of the touch screen frame. They ensure primarily a tight fit of the touch screen with the lower frame, and secondly protect the circuit boards installed on its backside. The top cover frame is made out of stainless steel. It protects the LEDs and is secured in its place at the corners of the frame. This completes the project.
