A No-Touching 3D Computer Interface

timothy posted more than 5 years ago | from the in-development dept.

Input Devices 123

Justin Schunick points out a video demonstration of a 3D input system which senses the user's hand position, but without requiring the user to touch a controller or wear a trackable position indicator. From the provided description: "Utilizing the theory of electrostatics, we have designed a low-cost human-computer interface device that has the ability to track the position of a user's hand in three dimensions. Physical contact is not required and the user does not need to hold a controller or attach markers to their body. To control the device, the user simply waves their hand above it in the air."

a 2d drawing application for a 3d interface? (4, Insightful)

Can't RTFA at work, but the obvious answer is "you make a gesture that signals you're detaching from the controller".

Re:a 3d I/O application for 1d data entry (2, Interesting)

MickLinux (579158) | more than 5 years ago | (#27747197)

Actually, I think a full-blown sign-language would be great, especially for use with cell phone cameras. There are a few obvious benefits, and some not-so-obvious ones:

(1) people learn international sign language, and it assists in international communication.
(2) The speed of data entry would be increased greatly.
(3) It seems to me probable that there would be decreased cost and possibly (if it was done by a designed/dedicated chip) decreased battery usage by using sign lanugage instead of other means
(4) Logon would be simplified, with simply flashing a thumbprint.

How to do it? I suspect that the way to do it might be as follows:
  (1) take an image, and subtract one image's RGB map from the previous image.
  (2) Run an FFT on the result, to get a motion map.
  (3) Track the motion of the various blocks of pixels.
  (4) From the motion of the various blocks, and moreover from what remains invariant and what adds on on one side (or disappears from the other), obtain a 3-D map of various objects. From the 3-D map, and how it morphs, obtain approximate rotation vectors.
  (5) Recognize hands by the digit lengths and connection combinations.
  (6) Plot the hand digit rotational and bending angles into a real-time motion map.
  (7) Translate #6 into specific signs, which in turn can be programmed to be equivalent to international sign language.

The above method would also allow very high levels of compression of video.

Jurily (900488) | more than 5 years ago | (#27747643)

I'm a Hungarian, living in the UK, posting on an American website. Don't tell me about international communication.

(2) The speed of data entry would be increased greatly.

Compared to a touchscreen, maybe. Assuming of course the software can translate SL into your native language. Compared to a keyboard, this is a joke. Try coding C in sign language, and report back when they let you out from the mental institute.

(3) It seems to me probable that there would be decreased cost and possibly (if it was done by a designed/dedicated chip) decreased battery usage by using sign lanugage instead of other means

You mean a high quality (especially considering #4) camera and a custom-designed and -manufactured chip or recognition software with the associated CPU load vs. a $10 keyboard?

(4) Logon would be simplified, with simply flashing a thumbprint.

Fingerprint is not a secret. Repeat that until it sinks in. (They use it to catch criminals because we leave them all over the place, you know.)

If my experience with a Theremin means anything... (5, Insightful)

nani popoki (594111) | more than 5 years ago | (#27745089)

... then maybe a no-touch interface is not going to work well for me. I found the Theremin to be almost impossible to play because there was no way to get my hand in exactly the same x-y-z coordinate and with the same roll-yaw-pitch attitude (all of which affected the frequency of the oscillator). YMMV, of course.

foniksonik (573572) | more than 5 years ago | (#27745261)

Just needed to turn down the sensitivity a little... like people who put their mouse on super slow tracking vs. those who prefer a quick twitch approach. Personally I'd like a trackpad replacement with this interface, I don't want to have to move my whole arm around. Make it plenty sensitive or rather make the sensor's grid scaled appropriately for the size of the input.

The only thing that affects the frequency of the oscillator is the distance of your hand - any part of your hand - from the antenna.

Re:If my experience with a Theremin means anything (1)

bughunter (10093) | more than 5 years ago | (#27747487)

Furthermore, there's a lack of precision. A useable touch-free interface must recognize hand gestures, even if just a state toggle ("active/inactive") and a binary command ("mouseup/mousedown") if not for a whole range of gestural commands. This appears to just detect limb position, which will inevitably lead to the kind of HHGTTG situations earning scads of +1 Funny mods ITT.

Re:So the reinvented the Theremin? (2, Informative)

artg (24127) | more than 5 years ago | (#27745937)

No, with USB instead of audio. The measurement is electrostatic either way, but in the Theremin the capacitance change alters the frequency of an RF oscillator. By mixing (ok, heterodyning) against a fixed oscillator, a varying audio tone is produced.

In this case, it's still measuring capacitance in some form, though with several sensor plates to provide more axes. But the result - however it influences the circuit - is generated as a stream of data over USB. It might even use a bunch of oscillators just like theremins to measure capacitance, but it would be hard to stop them affecting each other.

I don't know about everyone else, but holding my hands anywhere in free space takes quite a bit of energy unless they are hanging at my sides. The reason the keyboard and mouse or other touch surfaces work well is because they allow a person to rest their limbs in an unnatural position.

Though I do like the idea of having the mouse clicker on the thumb and forefinger as suggested by one of the other posters.

Most people use their keyboards and mice for about 5 hours a day. (IT related work) Hold your hands out in front of you for 5 hours. You wont be able to.

Please don't bring back the U-Force [i-mockery.com] ! It was the only peripheral worse than the Power Glove. Why don't you stay dead you bastard input device?

Man, this could be sweet. I for one cringe every time a colleague of mine comes to my office and touches my LCD screen to show me something. I really do. And when they leave, I pick up a towel to wipe it until I'm sure there's no trace left.
Yeah, I guess I'm weird...

Sub-etha radio! (1)

david.given (6740) | more than 5 years ago | (#27745923)

The master said it first:

A loud clatter of gunk music flooded through the Heart of Gold cabin as Zaphod searched the sub-etha radio wavebands for news of himself. The machine was rather difficult to operate. For years radios had been operated by means of pressing buttons and turning dials; then as the technology became more sophisticated the controls were made touch-sensitive --- you merely had to brush the panels with your fingers. Now all you had to do was wave your hand in the general direction of the components and hope. It saved a lot of muscular expenditure, of course, but meant that you had to sit infuriatingly still if you wanted to keep listening to the same programme.

Most people here don't realise that your arms don't get tired after 5 minutes of using this. If your arms DO get tired, don't blame the interface on your pathetic physical nature.

Secondly, since when is someone going to be using this non-stop for 12 hours? A lot of people here again, incorrectly, assume one will be using this machine for prolonged periods of time.

Do It Yourself (1)

I'm at work so I can't view the video, but I found something that might be similar that you can do yourself (if you have soldering/wiring/programming experience)

Pretty cool stuff.

I balked at the cloth as well, but stuck out the video to the last quarter, where they pulled it back and gave a short tour of the guts of the system.

Looks pretty simple. I don't think any new discoveries have been made, but rather the device is a clever bit of engineering using known electrical properties. Applied and scaled correctly, it holds some neat possibilities, though without some form of tactile feedback it might be awkward to manage information with one's hands in that manner. But who knows? Humans are good at adapting. The basic keyboard input seemed pretty impossible when I was a kid, but now my fingers are able to fly across the keys.

I think I would hate this possibly even more than touch screens (if that's possible). What's wrong with having buttons? Am I the only one who enjoys the feedback of a good clicky button?

I think this is an amazing project, especially for college seniors. Remember it's only a proof of concept, I'm sure it can be made smaller and more aesthetically pleasing.

3D Tracking for VR (1)

cowtamer (311087) | more than 5 years ago | (#27748459)

I was looking at this as a replacement for WAY more expensive systems like OptiTrack [naturalpoint.com] or the Flock of Birds. It's a bit limited in that it does not seem to let you "point" at a certain things...the video looked like it created a "bump" roughly where your hand is.

I wonder if you could refine such a system using electrostatic sensors alone to resolve individual fingers and hand orientation.

With some refinement and augmentation from a single camera, it could turn into a gesture recognition system for VR or a video game interface much better than the Wii. Of course, it still doesn't solve the head tracking problem... [Perhaps full-human body tracking with a bunch of these sensors behind a 3D projection screen?]
