The touch screen existed for many years. We can now see them in some restaurants and other businesses. Many phones also allow a simple touch of the screen to pick up, dialling, searching for a contact.
However, recently, an innovation will revolutionize the use of computers. This is the multi-touch interface (multi-touch) that you can experiment with the iPhone.
The single finger replied the mouse operation. The multi-touch to command the machine more rich and complex actions. For example the zoom of the iPhone, the shift to the next or previous page, rotating an image.
But more than this type of interface allows to consider a real collaborative work of several people on the same screen and thus on the same data. Everyone around the screen - in this case a table - can slip, modify data, together with other individuals.
Although Microsoft released since November 2008 table "surface", it is not now a common product. In addition, the price is prohibitive.
Yet a group of academics, handymen and users have experienced various construction methods such touch tables and put their knowledge and experience available to all via the Internet.
It is the result of their work in the book "Multi-Touch Technologies" and on the website NuiGroup (Natural User Interface).
Then you could get started in the realization of a touch table. The construction of such a table will be the theme of this article series. I invite you to monitor progress, pitfalls and results.
