There's obviously a rational explantion. And there MUST be some relationship between the book and pen somewhere.

I didn't bother to google it, this video is just to say I'm impressed, not stupid :)

Merry Christmas.

  • Hey There,

    I am a product designer at Leapfrog who makes this Tag pen. The pen has a camera inside that reads a semi-transparent dot matrix that is printed on the pages. Cool eh??

    Cheers,

    Joe

  • Hey Joe,

    Clever indeed, I think I made a video explaining it when I zoomed in with my usb microscope on the dots. I definitely made the vid, not sure if i uploaded it or not.

    Clever stuff, cool job.

  • Magnetic ink, its used in money too, thats so money counting machines can tell the differenc between £20s and £10s. The library in the Uni of Brighton stamps the books with magnetic ink and if you dont put the book on their system b4 taking it out the alarms go of at the door

  • Actually, it's a lot simpler than that. This wasn't a video asking how. Seems I was misinterperated, maybe I should do a video showing how. It's actually very clever.

  • Cool product. I think a good aid for learning.

    I'm gonna research this one.

    (You have kids!?- unbelievable!)

  • The sexual side of those womenfolk is most enlightening, you should try it sometime.
