Today’s desktop computers can be regarded as evolution of the typewriter. They are well suited for office applications but far from optimal for e. g. mechanical design, traditionally conducted on large drawing tables. Large screens are nowadays widely available for table-like computer workplaces. But their resolution is still too poor. To overcome this drawback the »fovea-approach« has been developed. A slim tablet PC (the so called Fovea-Tablett^®) can be put deliberately on top of a large table screen. The position of the tablet in relation to the table screen is tracked and the screen content of the table display just below the tablet is displayed on the Fovea-Tablett^®: just as if one would look through the tablet onto the table but with higher resolution. Whereas the table display is still good for overview, the Fovea-Tablett^® brings highest resolution to the region, one is just focusing on.
