The stylus strikes back
Back to the Future of Handwriting Recognition
1960s computer wizardry has commenters yelling “we already had this?!”
TLDR: RAND’s 1960s GRAIL system let people write directly to a computer with a pen and recognized much of it in real time, which still feels shockingly modern. Commenters turned the story into a mix of nostalgia, Palm Pilot jokes, and amazement that old-school visionaries were decades ahead of the machines built to support them.
A half-century-old computer project just swaggered back into the chat, and the crowd’s reaction is basically: wait, the future was already here in the 1960s? The article revisits GRAIL, a remarkably elegant system from RAND that let people write and draw directly on a tablet with a pen—no keyboard, no mouse, no button-mashing circus. If users wanted a box, they drew a box. If they wanted text, they wrote it by hand. And somehow, on the giant machines of the era, it could correctly recognize about 90% of symbols from first-time users. Yes, people in the Lyndon B. Johnson era were living out an early version of the touchscreen dream.
But the real fireworks are in the comments, where nostalgia, disbelief, and a little gadget-history snobbery collide. One old-school voice shrugs, essentially saying, kids, you don’t know how hard handwriting recognition used to be—a reminder that this was once one of computing’s trickiest puzzles. Another commenter instantly turned the whole thing into a retro-tech meme by declaring, “Oh hey, it’s Graffiti!”—a callback to Palm’s handwriting system that had readers mentally dusting off their styluses. And then came the big wow-factor comment: “That Alan Kay video is unreal,” with the spicy take that the dreamers were way ahead of the hardware makers.
So the mood is clear: part awe, part “history repeats,” and part comedy roast of modern computing for still not feeling as natural as a machine from 1966. The unspoken diss hanging over the whole thread? Sometimes the old ideas still look cooler than the new ones.
Key Points
- •The article revisits RAND Corporation’s 1960s GRAIL system, which used a pen and tablet instead of conventional input devices like a mouse or keyboard.
- •Gabriel Groner developed a handwriting-recognition program for GRAIL that recognized letters, numbers, punctuation marks, and geometric figures.
- •The article says Groner’s recognizer ran in real time on an IBM System/360 and correctly identified 90 percent of symbols drawn by first-time users.
- •The essay is designed as an interactive companion to Groner’s 1966 memorandum *Real-Time Recognition of Handprinted Text*, with a simplified implementation that recognizes uppercase letters and numbers.
- •The RAND tablet used with GRAIL measured 10.24 by 10.24 inches, had 100 lines per inch resolution, and reported stylus position every four milliseconds.
