TL;DR
Fifty years ago, the RAND Corporation developed GRAIL, a handwriting recognition system that allowed users to interact with computers using a pen and tablet. GRAIL's design prioritized natural user communication, making it a pioneering tool that remains relevant today.

Key Takeaways
How It Works
Groner's handwriting recognition scheme involves smoothing and thinning techniques. Smoothing averages new data points with previously smoothed points to reduce noise from the tablet's discrete grid.
Thinning removes unnecessary data points by discarding those within a defined proximity to the last accepted point, thus simplifying the input while maintaining essential stroke characteristics.
