It reminds me of the Palm handwriting recognition system. I liked there was no pretensions of natural handwriting recognition on the Palm. The awkward way you had to draw letters with the stylus was part of the UI, so little stroke order hints were displayed on the screen while you were writing. It made for a fairly efficient input system after a bit of practice, like txting on old phones.

I assume the Palm system worked on similar principles to GRAIL.
