is the best interface for entering text into a pen computer? The
earliest pen computers used AI programs that tried to interpret
a user's natural handwiting. In 1993 paper, I argued that it would
be better to require users to learn a specific way of writing.
I will discuss the motivation of my proposal, and whether it still
makes sense even as handwriting recognition technology improves.
I will also report on developments since my original paper. This
will include some little known systems and some (relatively) well
known systems such as Dan Venolia's T-Cube, Ken Perlin's Quikwriting,
and the best known of all, the PalmPilot's Graffiti.
