Multitouch builds are all the rage now, so it’s not surprising someone would come up with a multi-touchless interface sooner or later. [Hanspeter] did just that; his Multi-touchless ribbon controller, a.k.a. Polymagnetophonic Theremin is multi-touch without the touch.
[Hanspeter]’s touchless ribbon controller uses an array of 24 Hall effect sensors that activate whenever a magnet mounted on a thimble is placed near a build. These sensors go to an ARM-equipped Maple Mini to record multitouch events and send them out over Ethernet.
Even though [Hanspeter] is only using his “multi-touchless ribbon sensor” as a theremin, there’s no reason why it couldn’t be put to other uses. It’s entirely possible to place several of these magnetic sensors in an array and build a real Minority Report interface where the user interacts with a computer without touching anything.
After the break is a video demo showing off how much control [Hanspeter] can get with the thimble/magnet setup. There’s also a few demo songs made with SuperCollider showing off a trio of sitar/Moog/harpsichord synths.

good skill on playing at it :D
that sounds awesome….perfect for some dubstep wobble synth!
this is an amazing piece of kit!
cool sounds and what looks to be quite a “tactile” response.
im definately ordering some extra pcb’s with my next batch.
Or he could embed a magnet in his hand instead of using a thimble.
If you were going to make a touchless interface for text-entry, one possible layout might be a 6 (un) button touchless keyboard, like the ghost of a microwriter.
Much younger me used to use one at work and it’s a very intuitive system to learn, and would be very easy to implement.
The interface in Minority Report is not fictional. It in fact is real. http://oblong.com/ Used the movie to debut the technology. As for clear screens, look up HOLO Projection(similar tech to the tupac a while back). Since it was so out there and was in a movie people thought it was fiction. Well it is not and here is the place http://oblong.com/
Freespace control interfaces will be successful in CAD and similar applications.
Minority report style control interfaces will not, apart from sucking budget dollars into the “well, it seemed like a good idea at the time” zone.
To clarify: Free space gesture tracking is here to stay.
But if your application has a minority report style control interface, you just haven’t put enough thought into it. Remember the giant nuke plant/space command looking displays of the 1970’s? Pretty, but useless.
Yeah, it’s like that.
