ZCam 3D Camera Is Like Wii Without Wiimote and Minority Report Without Gloves
Posted by Jesus Diaz at 1:10 PM on December 16, 2007
The ZCam is the first low-cost, consumer videocamera that can capture video with depth information and probably the first real challenger to Nintendo's Wiimote: with its 3D capture abilities it will allow you to play Wii-style without using any controls whatsoever. In fact, it is so precise that it will even recognise your finger gestures to fire a weapon or manipulate your computer like in Minority Report, but without gloves or any other external device:
The camera has sensors that are able to measure the depth for each of the captured pixels using a principle called Time-Of-Flight. It gets 3D information "by emitting pulses of infra-red light to all objects in the scene and sensing the reflected light from the surface of each object." The objects in the scene are then ordered in layers in the Z axis, which gives you a grayscale depth map that a game or any software application can use.
According to manufacturer 3DV Systems, the depth resolution is quite good: it can detect 3D motion and volume down to 0.4 inches, capturing at the same time full color, 1.3 megapixel video at 60 frames per second. While there have been professional cameras with depth capture in the past, this is the first time that a device of such characteristics is cheap enough to be built into any game system or computer.
As you can see in the video, the ZCam is completely different from the EyeToy or any other normal 2D webcam. Even while it's not as precise and flexible as a real full 3D motion tracking system, the videos show that it can indeed provide with a new level of interactivity in video games and any application—like computer user interface manipulation.
While the results could be quite impressive, I'm not convinced about some of the applications. The flight simulator, for example, seems to work great. However, unlike boxing, I have the feeling that I wouldn't be able to control a plane without actually grabbing something. Of course, I can pick anything to give me that feeling, just like a Nintendo Wiimote. But then again, in flight simulator games you want an actual joystick, so the "phantom" feeling of not having force feedback is the same for the ZCam and the Wiimote. For any other game, like first person shooters, this kind of technology could be really good if it lives up to its promise and developers can fully exploit it.
Its virtues could be even easier to apply in computer applications. The demonstration in the video, with the guy manipulating Vista with hand gestures, gives you a very good idea. As I use my iMac 24 to type this, I wish I can just wave my hand in the air quickly to consult a PDF, like Minority Report's Tom Cruise but without jumping in the sofa and scaring Oprah. Or touching, moving and clicking the mouse.
Since the ZCam is a piece of circuitry that can be integrated anywhere, and without taxing the CPU, I don't see why companies like Apple or Dell wouldn't adopt them for future desktop and portables. However, the technology has just been officially announced this week and it's too soon too tell. Whatever happens, it's good to see such a device coming to the market. Hopefully, we will see it in action with real world applications soon. In the meantime:

Wasn't the ZCam originally developed for use in broadcast as an alternative to chromakey - giving a studio the ability to replace backgrounds without having to worry about having a blue screen and proper lighting - just using the depth information? If I recall, it was created by an Isreali firm and shown at NAB for a while and although people were impressed with the concept the overall "look" of it was still very rough and chunky, with hard jaggy edges. I'm wondering if this is the same product but just repurposed for the game/PC market? Curious.

I can see totally see this being used -especiallyu with a VR device or even trackir- for a completely real flight simulator experience, actually not for the joystick and throttle controls which can still be real physical objects, but rather for all the switches, radios etc.
In fact, I'm happy I haven't invested more than 100 dollars so far in my home cockpit :)

I'm far too cynical to believe that this is going to happen just because you've got some video.
It'd be even more awesome for boxing games than the Wii (which still hasn't released Fight Night Wii Edition, you stupid shits); there are definitely a lot of genres that I'd like to have something in my hand for.
Also, I'm waiting to see how FPS games are implemented. Basically, I'm waiting for something more than proof-of-concept.

This technology seems like something that could run parallel to the potential touchscreen technology has. That is, if there's something that could utilize this 3D cam techology the same way the iPhone/iTouch uses multi touch then happy happy joy joy.
Well, someone other then Nintendo that is, then again they seem to be doing something moreso in line with succeeding where the Power Glove failed.
And jesusdiaz: I thought it sounded more like they was saying "MASTER NINJA THEME SOOOOOONG!!".

Gaming to start with, but think about home theater setups. Be able to control your TIVO moving your hands. And I would to be able to casually wave my hand to have something happen in my computer.

0.4 inch eh, why not just say 1 centimeter.
I really like that this is possible now, and when they can increase precision you could use it as a 3D scanner for raytracing, or for simply putting your face on game characters too, this has lots of uses and potential.
I just hope and pray they specify in their rights the technology can't be used by cops/homeland security and such.
IF it is all real.
I guess the jpeg group has to start adding Z depth to their specifications now

Sorry, Jesus. I thought the music detracted from the video. Love MST3K, but it didn't fit here...
I would love this camera on a laptop to manipulate screen windows. I wonder if they could have one that can also see your hands near the keyboard so small movements could be translated on screen. Looking at my 24" monitor in front of me it seems like it would be too much work to use as a main interface device on a big screen.

Fantastic! The possibilities are endless, but I wonder what the ergonomic fatigue factors are? It could be quite challenging to come up with a virtual control scheme that might allow game consoles to pick this technology up... Especially with the considerable durations of time some gamers spend gaming. As an example hold your arms out in front of you, and see how long you can do it comfortably.

Ear-bleedingly bad music aside...
It's a clever method of detecting depth information about visible pixels in the frame, to separate foreground and background objects.
The information that the camera ends up with, though, is more like a topographic map, than actually mapping 3 D objects, since you can't see behind objects, you can only see the depth of visible pixels.
According to this, the original application was "video-keying" without a monochrome background. i.e. greenscreen without the green.
[www.3dvsystems.com]
If they could improve accuracy, they could use this for orthotics manufacture (4 mm is not good enough).
Actually though, if you put down multiple cameras though, (synched for time windows on their infra red pulses to not interfere with the other cameras) you could use tomography to do a fairly good 3D, real time motion capture (at only 60 fps for now) without the annoying ping pong balls.
In my own field of medicine, using multiple cameras, I can see how this could someday be used for high quality kinematic capture in a gait lab for a very cheap price.

Robbo, I think this zcam is the same thing you're talking about.
[www.3dvsystems.com]
Videomatting without a monochrome background. Greenscreen without the green. It doesn't really make a 3D model, so much as a topographic map of all the visible pixels, showing distance from camera of every pixel, based on the timing of reflected IR on your sensor pixels.
The real key to using this as a computer control is coming up with a reliable, intuitive, OS that incorporates gestures in the air, no mean task.
With a bit of cleverness, definitely could do some great things with it.
If you set up several cameras at different angles, you can crunch a little math to do tomography, and do true, realtime motion capture without the "pingpong balls".
I work in pediatric rehab, and this camera might be really good for tracking dyskinetic and spastic movements to pull out meaningful gestures for communication. Also could probably use something like this in the gait lab as well, when the frame rate gets higher. The resolution isn't high enough to manufacture orthotics, but maybe then next gen could.
-
What is the core price of the chip since it's not mass produced yet? I suspect the D-channel detector chip has a much lower resolution than 1.3 MP... but the data is then mapped onto the 1.3M RGB visible pixels (figure it's not necessary to be that high in the D channel, because objects of interest are not going to be only 1-2 pixels wide).

The PC manufacturers will never adopt and bundle it until there is a slew of software that supports it and the software developers will never support it until there is substantial market penetration that will not happen because the PC manufacturers will never bundle it. Sony and MS may be all over it though as they struggle to catch up to Nintendo in the interface innovation category in hopes of attracting those elusive new casual gamers that are flocking to the Wii.

this is all about the price. which i've not yet seen noted anywherrrreeee. if it's like 20 bucks, then it might show up in a console. if it's "merely" say 150 bucks then there's no chance.
has anyone heard of a price?
The tech is improved on eyetoy (and web cam motion sensing) of the past by mixing int he depth sensing. but depth sensing cameras have classically had a small range (like 3 feet where it's accurate, though you can set this 3 foot range to be out a certain place in the room - it doesn't necessarily mean their shit only works in the first 3 feet of their demo machine. that would of course be retarded for a living room gaming environment... curioussss.). The other problem classically has been the need to put out a lot of infra red light. like A LOT. And if you pump out a lot of infrared light, you don't want ot be staring into it for hours on end. it'd be like staring into a halogen bulb. except IR is invisible so you'd probably just get mysterious headaches every day.
still. i haven't used their zcam. fingers crossed that it is both improved on past tech and cheap. (a depth cam i experimented with a couple years ago, just black and white depth data mind you, ran more than 5,000 bucks). I'm nervous that they're planning to cheat on the zdepth by working in the color data as well (eye toy style). hmmmmmm.

"While there have been professional cameras with depth capture in the past, this is the first time that a device of such characteristics is cheap enough to be built into any game system or computer."
Any examples of these professional cameras? If I could find something like this, but usable with real lenses (and 1080i resolution) I would drop $10k without having to even think.
I've been doing greenscreen work as of late to support a media project. Green backdrop, green floors, lighting rigs, renting space, *tons* of manual post-processing, ... A true 3D camera would eliminate so much work for me! Record, apply a clip plane for depth and the floor, and I'm done. It'd even make it feasible for me to record out door scenes, which would be fantastic!
And I'm just imagining all the fun, fun experiments I can run with depth extracted from scenes, both for coding projects and robots applications! Robust depth exaction without stereographical guesswork? I could chuck all my computer vision books!
The console / gaming focus for this device seems... odd to me. I'm imagining a ton of more useful applications.

This will probably make PlayStation partisans cry if it's really a Wii killer, but Sony demoed something exactly like this in one of business sessions at E3 2004, billing it as a possible EyeToy 2. There was a lot of buzz around EyeToy back then because it was the most successful console peripheral ever at that point. (This was pre-Guitar Hero.)
The proposed EyeToy 2 even used the same tech - pulses of infra-red light. I remember because the "how does it work" question came from Will Wright, and I think the guy answered almost out of reflexive respect before he realized that he might be giving out important trade secrets to a room full of strangers who weren't on NDA and might work for their competitors.
For whatever reason, the PlayStation Eye didn't end up using this tech.
