Kinect Can Detect Clenched Fist
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."
I hope the next Grand Theft Auto game is Kinect-enabled for pimpslapping.
We don't have a state-run media we have a media-run state.
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?
Cause that would speed up a lot of forum conversations.

a clenched ***** OMG!
Sega already beat them to the clentched sphincter http://www.retrojunk.com/commercial/show/10889/sega-saturn-commercial-the-theatre-of-the-eye

Can it detect middle finger though? I show it to Kinect all the time, and it seems to be ignoring it.
The dream of being able to punch someone through the internet took a step forward today.
Everything is better with chainsaws.
The biggest problem with Kinect controls is the lack of gesturing. This results in users needing to hold their cursor over a control for a couple seconds in order to simulate a click or button press. For obvious reasons, this makes the whole control scheme brutally slow. Even worse was the solution used in Child of Eden, where the user need to push their hand forward, thus making the Kinect controls much more difficult than using a normal controller. Just this one gesture to function like a mouse click will greatly improve the user experience for all OS/menu controls and many games.
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.

Do you still have to make a gun out of your hand and go "pew, pew" when you play FPS?
I haven't thought of anything clever to put here, but then again most of you haven't either.

Unless it can detect chairs (mid-flight of course), then I don't see it being much use for Microsoft!

So it knows when you are about to smash it?
Warning: this article may contain humor, sarcasm, parody, and perhaps even irony. Read at your own risk.
Such things have been speculated about as early as 2008 from what I can tell (http://www.wired.com/dangerroom/2008/07/wargames/)... I don't think it's actually the case quite frankly, it seems too far-fetched, but the kinds of science fiction that could be written about the idea -- an entertainment company batting advertisments about for their new video game technology, that can detect a closed fist, a concealed weapon, a facial expression that suggests aggression or a lie.
That same article linked to a picture from a British army TV advertisment in which a UAV was being piloted by a soldier...using an XBOX 360 controller. Now again, is MS hardware actually being used that way? Probably not -- but you know just by virtue of how sue-happy the U.S. is that Microsoft knew the controller would be on-screen, that its suggested use would be for piloting a drone...and they thought that, at the very least, it would be a good marketing opportunity? That's the kind of thing that makes most people say, "I wouldn't put anything past them."
ASL? That might be useful
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.

" long awaited 3D scanner Kinect Fusion"
There are already several open Source implementations in the PCL (pointclouds.org/) so there is no need to wait for Microsoft
to publish an SDK...
https://www.leapmotion.com/
And they just announced that they're shipping in May!
If you haven't heard of Leap Motion, check out this video: https://www.youtube.com/watch?feature=player_embedded&v=_d6KuiuteIA
Once you have that type of precision, I would imagine "learning" what a fist is wouldn't be quite as difficult...
We can finally actually punch someone in the face over the internet!

Next up; determining if that clenched fist is wrapped around something and is moving back and forth along the same mainly vertical path.
when, if the webcam sees a clenched fist and angry, set face, it reverts to Windows XP???
if this is supposed to be a new economy, how come they still want my old fashioned money?
What is so special about recognizing a fist that requires Kinect? A cheap camera with some visual recognition software can do the same and probably better and quicker. Just saying.
It's not easy to detect fingers at a distance with that type of resolution. I hear the Kinect 2 will have a higher resolution (made possibly by the greater bandwidth of USB 3.0) and lower latency. Kinect continues to rock!
I'm imagining the DLC for "Rock Band featuring Rihanna".
Dewey, what part of this looks like authorities should be involved?
