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

Bob,
Neat!
The video here reminds me of a theremin.
That's $70 end-user price, which makes me wonder what the "innards" ( "line laser" plus linear photodiode array? ) would cost if integrated into another product.
I also wonder what effect the technology behind this will have on the touch-screen panel market. Even the full retail $70 sounds like less than the cost for adding resistive or capacitive touch-screen support to, say, an LCD panel.

"But America is a great, unwieldy Body. Its Progress must be
slow. It is like a large Fleet sailing under Convoy. The
fleetest Sailors must wait for the dullest and slowest. Like a
Coach and six--the swiftest Horses must be slackened and the
slowest quickened, that all may keep an even Pace."

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.
Failure does not prove something is impossible, failure simply
indicates you are not using the right tools...

A single webcam would not give you range. Probably 2 webcams?
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.

Joseph,
Thanks for the update. I hadn't realized that the extra cost for "touch" had fallen so low.

Is it not fair to ask the technologist, not only to provide arte-
facts which work, but also to provide beauty, even in the common
street, and, above all, to provide _fun_? Otherwise technology will
die of boredom. Let us have lots of ornament. Let there be figure-
heads on ships, gilded rosettes on the spandrels of bridges, statues
on buildings, crinolines on women, and, everywhere, lots and lots of
flags. Since we have created a whole menagerie of artefacts, motor
cars, refrigerators, wireless sets, and the Lord knows what, let us
sit down and think what fun we can have in devising new kinds of
decorations for them.

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.
