I invented a solution for the problem that would allow you to fit a plastic
template between the keys without affection the size or shape of the normal
key tops. You could toggle between the normal and alternate keyboard
layout. You could replace the template and change the alternate keyboard
layout in less than a minute.
The problem was access to the keyboard drivers which are more embedded in
OSes than normal device drivers. A joined the ACCESS.bus working group to
develop hot plug & play standard that the entire industry would use. This
eventually led to the USB standard. Unfortunately Intel did not understand
the i18n portion of the A.b standard and implemented a worthless
accommodation in USB.
With the dramatic reduction on keyboard prices and the fact that you can hot
plug in two different keyboards on the same system I could not make money
with my patent. If you can not get a keyboard with the right layout you can
buy stickers for your alternate keyboard key tops.
There were LCD keyboards at about $4000 each that would only accommodate 7x9
LCDs which limited the vocabulary to languages with simple glyphs. There
was also a keyboard that projected the key images onto the key tops. The
keyboard had to be held ridged and was also expensive. IBM also had an
overlay keyboard but the keys were sort of like pegs.
Even though my keyboard would not be that expensive my market research told
me that the demand would be too small.
Use two USB keyboards.
