Gesture Laser Pointer Control

After I linked his basic laser pointer webcam interface the other day, [mnt] sent me this excellent demo of his gesture based laser pointer control. This one works alot like graffiti on the old palm pilots. My question? What does he make when he’s not sick?

  1. These things are cool i just wish there were more about it up… I’d love to see how it was done and how much programming was needed. Maybe at least some programs i can play with to see where to start on one of these of my own.

  2. to #5, thanks, I was just wondering, if you think it’ll stop spammers, you’d best leave it off, (though if someone wanted to, it probly wouldnt be to hard to create some sort of auto varification mail server)

  3. This is rediculously kewl
    is it possible to program it to do kewler stuff than that
    i wanna see that thing eventuallty be used by the millitary to remotley fire weapons now thatd be a good use. keep rockinm


  4. The only thing thing with the password verification is that you have to remember that random password… I personally disregard it since my e-mail is only a click away…

    And, yes it is a shame that the code isn’t released. Who wants to bet that in a few months this is a piece of $20-ware?

    I also second the IR laser idea, you could make the tv the target and use a webcam with the ir filter replaced with an visible blocking filter. Would be prefect for projector screens :)

  5. I can see some real-world applications for this one. It could really simplify presentation controls, for example. You wouldn’t even need a remote; everybody has a laser pointer! Well, everybody with a dog or cat, plus 95% of the rest of everybody.

  6. Yeah, there is absolutly no information there, just about as much info was presented on HACKADAY link page. Bleh, I wanna learn something, not just oggle someone elses goods. We need more information damnit! How about an idea of what this mysterious image recogniztion software is. Where do we get it, how do we work with it, how do you interface blah blah blah.

    Maybe some one can comment with a good link?

  7. Hey, I have managed to replicate this project in Java using the Java Media Framework; however, the only thing i am having difficulty with is recognizing the image as a character. I am willing to share my source with anyone who has some ideas for how to recognize jpeg image as a character. I was also debating converting the image to a list of lines to determine the direction to aid in recognition. Any ideas would be appreciated, and i will share my source with anyone who asks


  8. I really like flight simulation and was thinking of purchasing a product called trackir which follows head movement and lets you look around the cockpit. but this could totally replace it and save lots of money

  9. hey this is a really cool thing you did right here. Iw ould like to see how you coded it. What did you code this in. Did you just use a standard webcam or something more powerful? This is a neat thing with many things you could do with this. If you could refine this and get a better camera it could be a very powerful presentation tool. Steve youor an idiot.

  10. hey i have been looking for projects like this for a while and finally wrote a program that can find a bright spot (laser) and draw it on the box below. I have one problem with it right now and that is it is kinda slow. It wouldent be very hard to add gesture recognition as well into my program. I have the source files for download here It is programed in Visual Studios 2005 in VB. the file download is the entire project folder.

    The iCam.vb file is the webcam class you can use this independently of the program for use with a webcam on Visual Basic .net 2005. More information is on this website.

  11. Tired of a competitor’s site? Hinder the enemy? Fed pioneers or copywriters?

    Kill their sites! How? We will help you in this!
    Obstructions of any site, portal, shop!

    Different types of attacks: Date-attack, Trash, Attack, Attack, etc. Intellectual
    You can work on schedule, as well as the simultaneous attack of several sites.

    On average the data, ordered the site falls within 5 minutes after the start. As a demonstration of our capabilities, allows screening.

    Our prices

    24 hours of attack – $ 70
    12 hours of the attack – $ 50
    1 hour attack – $ 25

  12. I believe there is another way of doing this. I don’t think I can code that much, but with someone helping me out, probably we could figure it out… First, we find a tablet pc handwritten text recognition software. Second, we will integrate this in a webcam tracker. Finally, we assign the commands to the specific keystrokes. (well, at least we can find these simple software “open sourced”, just compiling them together will be a little bit hard) Anyone ? :)
