The problem with large character sets is not as great as might be thought. I remember reading about Chinese type setters having 'keyboards' with 5000 characters on them but only using a very limited subset of those characters. The paging of the character set could then be aranged so that the most commonly used characters are on page one and less commonly used characters on other pages. The other major points mentioned is that keys get dirty, you can't read the keys with you hands in the way, how would you connect the blocks of lcd ? Difficult certainly - dealing with the last point first : The blocks of lcd need not move. After talking with a physics graduate here it seems likely that if a prism were placed on top of the keyboard then the block could be fixed underneath this and the 'key' could move around the lcd display , this would remove the requirement for some sort of moving contact to the lcd, the prism could also offer some magnification. The other points : If you are aware of the layout of the keyboard (ie not looking at it) then you need not worry about your hands being in the way of the keys, you aren't looking anyway. The point about a re-configurable keyboard is that its main use is when the layout of the keyboard is unknown or likely to change. Personal hygene is a matter for the individual. Craig.
