VJ Fader faderTouch Processing – BeiJing studio 1 from VJFader on Vimeo.

Multi-touch projection is now easy to do with free software, a projector, and a projection surface. The trick is making a controller that is more portable. VJ Fader has a nice, home-built rig, seen here controlling Processing sketches. It uses a 10-lumen pico projector, and a mirror to shorten the throw distance required. I might be inclined to go slightly larger than the pico, as there are now ultra-compact projectors in the 100-lumen range (or even greater) that add only a little size but a lot of brightness. Here’s hoping for some Black Friday / Cyber Monday projector deals, eh? (That’s right, economy. You know you’re hurting. You business folks are just going to have to use white boards and give all your projectors to us.)


It seems there should be some ways to continue to refine the form factor to make this easier to carry. Of course, an even more compact setup would be one of the new laptops available with multitouch screens, from vendors like HP and Lenovo. But those machines aren’t yet paired with high-power GPUs, and unlike a projector, your audience can’t see what you’re doing. They’re also less suited to collaboration, whereas a screen like this can be easily shared with others. I think even if multitouch becomes more prevalent and Apple introduces the Tablet some of you are apparently awaiting, there will still be a case for the projector screen.

Processing users, if you’re looking for multi-touch control, I can wholeheartedly recommend the new MT4j “Multitouch for Java.” (An uncreative, but descriptive name.) It’s actually built in Processing:

    Yo Fader,
    Nice work, here is a idea to check out.

    Together this cost $500 bucks from Digi-Key.

    If Digi-Key keeps this price this would allow us to build
    real time video effect synthesize, like Freej in a box with midi controller and touch control and real time video input.

    This turnkey system could allow us to build low costing real-time effect systems with HDMI out.

    Roland watch out the Video Boss effect system is coming.

    Sorry, I forgot the prices-
    beagle board $150
    Pico projector developer kit $350

    for a video effect synthesize
    beagle board $150

    FreeJ or Processing $free

    I would love to for now have FreeJ or Processing on a running beagle board, dedicated system and out the box works a Korg Nano controller and/or multitouch to keep it simple.

    @djvideomycode wow, thanks for the link the B.B. looks amazing. It even has S-video out! Dear Santa…

    pretty cool idea!
    although i would debate the use of the word "mobile".

    maybe i could fit it my backpack next to my mobile grand steinway ;-)

    If you think the BeagleBoard is too big, you can look at the Gumstix Overo. Considering the BeagleBoard takes under 2W and the Pico is under 10W, you could use a pretty small battery source.

    here is a great resource for touch screen UI elements / sofware / components. BEWARE: it is a huuuuge list
