Taking the Wii Controller to the Next Level 157

funfail writes "It's a Wii without the $250 console. It's virtual Pong and so much more. Any object is now an input device, even your fingers. Camspace is a pure software solution that allows nearly any ordinary PC webcam (95% are supported) to track up to four objects — even as small as 5mm — in real-time and with very high accuracy and reliability (Windows only). Techcrunch has an in-depth article and a video." Very neat idea, but it appears that it is in a limited beta only, and source doesn't appear likely.

          The eyeToy doesn't work on the PC, so there's no loss of market share.

          If their patents cover all of these style of input devices, and not just PlayStation versions, then the patent office has a serious case of cranio-rectal inversion.

          Also, the webcam + game thing isn't anything new. I remember buying a webcam back in 1999 and it had games as such included on it like this. you sit in the little outline it has on the screen and move your arms around to pop bubbles... or whatever have you. Nothing new. Sony has no grounds for a lawsuit, as it had happened LONG before their eyetoy was ever released.

    This certainly seems to be a very nice software, but the main issue with using webcams as input devices is the latency. Your average webcam can take quite some time between what it's filming and what the PC is actually getting at the other end. And this is a very bad thing when it comes to gaming. You can even see the latency in their video at around 1:30 when they have the players and the PC screen in the same frame.
    Nice for simple games I guess, but for serious gaming it would require special cameras with low latency.

      Yeah the video is hard to believe. I've done lots of work with image processing using webcams and they're usually pretty crap. You can get 30fps max, and then usually only at 320x240. If the lighting conditions aren't good, your framerate will drop (or everything goes unusably dark if you disable the automatic aperture adjustment).

      They show some latency, but overall the motion is incredibly smooth. Based on my experience that's impossible, but I'd love to be proven wrong. Gotta try that out.
      • Typical firewire webcams are now often hard to find, except sometimes very cheaply as discount surplus :) DV is an acceptable quality/resolution...
      • I've seen a bunch that tend to do between 22-35fps at 640x480. I guess the resolution would determine how small of a 'tracked' object you could use, but what do you need really high FPS/resolution for?

        High resolution=tracking smaller details, but most are probably going to be not too hard...

        At 30fps, that's about one frame every 33 milliseconds, which is a decent enough refresh for a lot of inputs, and less than some people get as a ping in online gaming.
    • Besides, the webcam may have a hard time tracking Z-axis direction, pitch, and acceleration in the same manner that the Wii provides. Perhaps if they let you track Wiimotes with this device it could yield greater accuracy, but then you are right about the latency issue. A neat trick, but for hard core games it won't do the trick.

        Well the genius of the wiimote is that it puts the camera in the controller, and the things the camera tracks are fixed points. This makes measuring Z-axis easy (distance between the points) as well as pitch (apparent angle), using only the small wiimote.

          Actually, the wiimote is somewhat limiting in it's tracking capabilities (but fortunately in a way that isn't usually apparent). The wiimote can't tell whether or not it's looking at the sensor bar from the side or not, when you move the wiimote left or right, the two lights appear to get closer together in the same way as if you'd moved it further away from the television.

      Open source = good
      close source = good

      freedom = good

      being forced to open or close one's source = bad

        Of course in reality it's easy to see that slavery is bad for society as a whole even though it makes some people better off. The same is true with software freedom. In both cases, the overall freedom of society is more important than the individual right to restrict or remove the freedom of others.
