"Leap Motion": high res 3D motion detection

https://www.leapmotion.com/product

10 finger motion detection to 1/100mm (!), at 290 fps, in 8 cu ft of
space. $70. WOW!

 

Could be a big hit once they start delivering in volume...

 

Pretty nice item... Thanks.

 

I'll bet you could easily write a "Theramin App" for that.

And considering the resolution, it would be quite precise.

I have "pad" apps for my iPad from Moog and Akai and other big names.

Really nice synth apps. The "pads' are similar in operation to the
theramin, only 2-D.

 

At the bottom of the page:
* The Leap Motion controller works with Leap-enabled software only.
Functionality may vary depending on software.

How useful it becomes depends on how widely accepted it is, though.

 

Its just another Kinect but optimised to recognize fingers. IOW it is
a simple infrared webcam. The heavy lifting is probably done by the
host CPU.

 

I wonder if the monitor's light is a requirement for it to
operate.

Not so much to add touch screen, maybe us$ 0.40 at assembly time. Maybe
us$ 10 at retail.

Volume baby, volume, > 1E7/year.

The case appears to be a hard IR-bandpass filter, making that
unlikely.

There are some really interesting ideas here about lensless optics:

which lead to addt'l interesting topics. Point being that a lens sums/
redirects many source rays onto one point on the imaging array. That
destroys position information. If you don't do that, you can compute
position from the image, re-focus after the fact, etc. Neat stuff.

 

It may not actually be that low, but the volume is at least that high.
Every bloody smart phone and tablet; and a bit more.
