Kinect Can Detect Clenched Fist 65
mikejuk writes "Microsoft Research is currently having a Techfest at Redmond where it is showing off a lot of new work. The latest work on the Kinect uses the same sort of machine-learning approach to distinguish between an open hand and a clenched fist. Although there are no details, its general method was to use a large number of images of people's hands and supervised training to distinguish between open and closed hands. The learning algorithm is based on a forest of decision trees, which is the same general method used to implement the skeleton tracking. Being able to detect an open or closed hand might not seem to be much of an advance, and certainly not as good as a multi-gesture touch screen interface, but it is enough to allow the user interface to distinguish a "pick up" or "grip" gesture. So you can move the hands within an image, close both hands to grip the image points and move apart to zoom. You can't get the software at the moment, but it has been promised for the next version of the Kinect SDK for Windows along with the long awaited 3D scanner Kinect Fusion."

What I don't get it why isn't there more noise about a wii remote-esque controller for the Xbox? Seems like that would complement the Kinect wonderfully, the one catches posture and absolute position, while the other catches the subtleties of acceleration and orientation of your hands and provides buttons for precision input. Throw in a VR helmet when the Occulus Rift hits the stores ad you'd have all the pieces to take the first steps into consumer-grade VR.

I get that this could be great for mimicking the mouse click/drag, or for interactive boxing games. But what about its law enforcement potential? How long until this is used to detect possible domestic violence?

You think most domestic violence is done by people who can afford a brand new console and peripherals?
If it ever was possible, people would just leave the room to do that sort of thing.

Years ago, I had a black dude come in with his kids and ask me about xbox at my college job, he was asking release dates or something, and I told him you could find that on the internet... guess what he didn't have. My point is never underestimate people's distortions of priorities.

Don't know if you realize that your statement comes off as having a secondary implication, but that same story works great without the skin color being mentioned:

Your Xbox isn't sentient, you know. But even if it were, why don't you just throw the controller against the wall.
Because Xbox controllers are expensive and fragile. With the NES I could vent my anger by swinging the controller by the cord and bouncing it off the (lino-covered plywood) floor as hard as I could, and then I could go back to playing...

It doesn't detect it because it assumes it is a penis. Don't wave it around, because then the software will interpret it as a penis helicopter, which will get you a perma-ban on Xbox Live.

Microsoft demoed at E3 this two years ago (Score:3)
The did it at E3 2011 where Kinect Fun Labs was showed.
The guy demoing it waved his fists around and it tracked them. When he put fingers out on one hand he was able to draw lines on the screen, it saw the finger out.
In that case and this one too it was clear that this was so close to the limits of what Kinect can resolve that it wasn't going to be reliable in normal use. But it did work on stage.

MS claimed they would ship this, even named it "Kinect Finger Tracking". But it didn't ship yet. It's likely the current hardware just isn't reliable enough at it.
Re: (Score:3)
The commercial Kinect cameras are 640x480. Even if that's decent for finger-level tracking close up, a method designed to measure the activities and placements of fingers close to the camera is not going to have enough data to work on hands further away.
That being said, it does appear that the demo in the video you linked has sufficient discriminatory power that a fist should be relatively easy—he's not exactly holding his hand right up to the lens.
