 A
new trend in Personal Computing is to market PDA appliances: the so-called
Personal Digital Assistant. Important examples of these are: the Newton
of Apple and the Zoomer of Casio/Tandy. PDAs are characterized that they
do not have a keyboard but that they worked with a well developed graphical
interface in which handwriting recognizing a key function has. For this
there is developed a separate operating system: Pen-OS. With a (special)
pen one can use the machine, icons are touched in order to start a function.
Short notes can be made/written on the surface of the screen. The software
will recognize the handwriting and convert this to machine writing. This
recognition does not always work fool proof, sometimes even very bad.
