this seems like a pretty kool project and at just $50, thats awesome.

Wow, just wow, great idea and implementation. The responsiveness and pressure sensitivity when compared to visually done multi touch is daunting.

I’m going to go home from work today and glare at my multitouch system with geek shame.

Thats awsome! i love how it reacts to varying pressure. I can think of a heap of uses for this little beauty!

As The same kind of tool that the reactable do, that is very cool to see the 3D graphical at the same time of the user touch.

Awesome.

I’m amazed by the responsiveness of
this touch device.

Very impressive results. Are there any occlusion issues? It seems that if you used more than 2 fingers there are some cases a third press might get masked or worse incorrectly cause the other 2 points to show increased pressure.

this reminds me of the Unmousepad device I tried this fall, made by Ilya Rosenberg and Ken Perlin from NYU. (see http://www.youtube.com/watch?v=jxibIAHndl0)

$50 … plus $1000 DSP box for signal processing

@rasz
I think you can do the processing
on your computer instead.
It would not be resource intensive
AFAIK.

I would say that its almost innovative.

happypinguin there is 400KHz sampling mentioned in the vid, that means expensive sampling card for your computer (or 848 TV card if you know how to hack one), but you still need to write the DSP code. Looking at the link there is no code published (apart from some libs for the commercial touchpad called MSP)

@Raz

Granted this is also geared towards audio and instrument enthusiasts. not your standard instructables freak

Ok i understand how i could do this. i have creamware scope SDK(lots of DSP on a PCI card) and a spare fostex cheapo ADAT interface.

sending 10-20 khz audio waves, easy.

send the returns to the front end of a vocoder to get seperate control signal for each frequency.

after that is the “centeride function” im not so sure about that :p

It would be interesting to add some sort of display overlay to the device for visual cues/feedback, making an even more immersive, intimate controller.

how about a stringless guitar using 2 of these panels, one for where you pluck the strings and one for where you hold them down. use copper wire on top instead of copper strips.
