Wearable Inertial motion sensors

[eight]

Here is the download link for the CocoKinect.app.zip, which will stream OSC signal understood by RAMDanceToolkit, using either kinect or an oni recording.

Usage scenarios:

-- If you launch CocoKinect for RAMDanceToolkit with kinect attached, it should just work.

-- Launch CocoKinect for RAMDanceToolkit with no kinect attached: At this point you have an option to plug kinect in and hit Reset button, application should start reading from the kinect. Alternatively, drag and drop an *.oni file anywhere on the application window.

-- If, at the moment CocoKinect is playing an oni file, you can connect a kinect and hit a Reset button, the app should start streaming from the camera instead of file.

If you feel like minimizing the amount of graphics pushed into your graphics card (with CocoKinect, RAMDanceToolkit and Isadora running you may need to), hit the "Display" button.

All dependent libraries are shipped together with the application, so that there is no expectation of any previous installs of things like libusb and/or libOpenNI etc. It was compiled against SDK 10.7.5, tested on 10.7.5 and 10.8.4.

This is brill thank you.

[Michel]

Thank you very much for sharing.

[bruper]

@eight thanks but what OS are you using? it doesn't work on 10.6.8
no, I'm wrong it does work , well done, expect it's intermittent on Syphon...

[Michel]

I did not try it yet, when I find time I will. I am on 10.8.4.

Best

@bruper –– it is compiled against 10.7.5 (I don't have 10.6). Tested on 10.8.4 and 10.7.5.

this is the time that I'll have to upgrade... also 1 (perhaps stupid) question. How can I send OSC from kinect simultaneously to 2 applications?
Normally if I use 1 address OSC signals in one application, if I try to use the same address in OSCulator it will not accept it. Is there a kind of ... "splitter"?

thanks

[eight]

@bruper: Check this out. I haven't tried it, but it seems what you need.

Thanks for the link above @eight.

I was looking for something like this a while ago. Splitting OSC is not as easy as MIDI (or virtual MIDI)

[bruper]

@eight, thank you very much.it works with the Terminal, will have to investigate

[dbini]

hey @eight, thanks for building this. i got excited and tried it out with 10.6.8 but it didn't recognise the kinect. so i bit the bullet and upgraded to 10.8.4. fortunately everything seems to work fine on my mac, except Cocokinect still can't see my kinect. any ideas? Bruno - how did you get yours to work after your upgrade?

[Fred]

You can use a multicast address to broadcast OSC to multiple ips at once. If you are working on the same machine you cannot bind two apps to the same port so you have to code in that you send to 2 separate ports (sending two messages). You can do this with OSCulator.

Check the addressign section of this

same as dbini, doesnt recognize the kinect. I´m on 10.8.4

Guys, these are the sources for RAMDanceToolkit+Syphon and CocoKinect for RAMDanceToolkit (could be used for debugging or recompiling for other SDK's).

If CocoKinect does not see kinect:

-- if the app starts, it means that all the libraries (usb and openni) have loaded, and it's up to them to see the kinect;

-- if your kinect is not recognized, please keep in mind that openni version used is for older kinect models (not 1473).

-- if you have an older kinect and program still does not see it, check if an oni file can be played (I have used [these](http://people.cs.pitt.edu/~chang/1635/proj11/kinectRecord) ones for testing).

To see a more detailed output on the console, one can 

   -- open terminal

   -- cd to ../CocoKinect.app/Contents/MacOS

   -- execute ./CocoKinect 

   -- examine the messages

However, if kinect is not recognized, you will see something like "Device not found" –– which is produced by OpenNI library -- not very helpful, but at least it will confirm that the problem is not in CocoKinect, but in openni/libusb/hardware realm.

Lastly, confirm that your kinect is seeing by a regular Openni program, such as NiViewer, to exclude a hardware issue.

@Fred, thanks will investigate, what I would like to do is to send Kinect to CocoKinect and simultaneously to other application to produce sound for instance.... John, I haven't upgraded yet. With 10.6.8 I get intermittent visuals on Syphon... anybody experiencing the same with upgraded OS?

[dbini]

hey @eight: here's what's happening: CocoKinect opens and runs ok, asks to plug in kinect or drop *.oni file.

my kinect is of the older variety. it works fine with NI-Mate, so its not a hardware issue.

CocoKinect won't recognise when i've plugged in my kinect and reset, or if i drop an oni file from the resource you linked to.

[eight]

@dbini I found a spare mac and was able to reproduce what you are seeing: NiMate runs, CocoKinect don't. This is a pristine (in relation to OpenNi) computer, while my other ones have had openni and NITE installed numerous times. Unfortunately, this is where I have to stop: I have another project pressing. Bottom line: try to install Openni, SensorKinect and NITE if your version of CocoKinect does not render. I read somewhere on the Openni Forums that openni will silently try to load the libraries, and if it can't find them, it will simply bail out without giving the reason.

cheers @eight, thanks for all your help. i'll let you know if i get it to work, otherwise i'll wait for something else to turn up. i know the guys at Delicode are looking into integrating support for RAM into a future release of NI Mate.

[Fred]

There is an openniOSC app included with the ram dance toolkit, it is calibration pose free and works very well- is there something that your cocoa app does extra- the OpenNIOSC does not already do?

[bruper]

anybody else is experiencing intermittent video in RAM-Dance-Syphon?? (in all the Mac OS's)
