      Was just looking for it and can't find now. Will try n throw an example Izzy file up later this evening.

      NB: if it cuts out and fails to start, and you end up stuck with a beachball, generally it means unplug / replugin your kinect... a resource hasn’t been correctly freed. Or, you’ve forgot to plug in the kinect PSU.

        If all you're wanting is a ghost mask there are other ways that don't involve OpenNI / user / skeleton at all, so can accept waist up etc... and reduces USB bandwidth & CPU load. Will see what I've got in my toolbox and start a new thread for it once I've found it.

            Wow! Thanks so much. Am checking the other thread too.  Ideally wanted to use 3 or 4 instances of the ghost, and one of skeleton, as I had wanted to do something where it started in the axis centre (solar plexus) in the chest and spread from there. But will see where I get to with this first as anything approximating would be great, and I may be able to opt for bigger centralised blur etc instead for now.

            I would be more than happy with one scene with 2-3 adjust keys, so it can all be fired up in one sitting. 
            Great to have the mask IZZY set up pic too. 
            If I was to use separate scenes, for separate FX using the ghost or skeleton, does the signal take a while to load, and does it interfere with the process if I am not always in view of the Kinect IR sensor?
            As in is it better to have one complicated scene where the signal is established even if I move in and out of shot, rather than jump between scenes each of which has the set up active as needs to be, user actors etc.   
            Ideally I would have more complicated scenes, which a keyboard watcher can trigger between.  At the moment, having achieved skeleton, and being blown away by the possibilities of all the information received and relayed, my head nearly popped, but for this version with so little time, a ghost IR will be more than great.
            One issue I have is my costume - in one scene its a straightjacket, and its lighting up the IR sensor (like its alive - why I don't know!!!), but obviously my arms aren't available to provide skeleton info feed. So again I think I will have to use the ghost only feed.  I'm guessing your Kinect Ghost Mask is going to save my proverbial.  Thank you once again @Marci

              Anything reflective... Buckles etc ...will reflect and scatter the infrared pattern that the Kinect projects and then detects. Use talc to dull off reflective fabrics, Vaseline to dull off metals. My glasses always cause problems like this... have to wear contact lenses if I'm working with Kinect.

                Aah, smart thanks for the tip.  It may work in my favour if I can get it to read blob and use IR when I am not in it.  Thanks Dude.

                  Hi!

                  Thank you for great work you do!
                  Following the tutorial I ran into a problem running Processing file on Mac
                  Error says:
                  "The method enableUser(int) in the type SimpleOpenNI is not applicable for the arguments()"
                  What is the problem here?
                  Igor

                    Having trouble linking my kinect to my mac. After I hit run in processes this is what happens.
                    I'm very new to this. If anyone can help I would really appreciate it.

                      Dear @Bunker,

                      Are you using Processing v2.2? As noted in the tutorial, SimpleOpenNI only works with v2.2\. It does not work with version 3.
                      As for the error in the third picture, the it should be "!=" instead of "!=="
                      Best Wishes,

                        Last error (third picture) is now fixed in the repo (must’ve been doing a lot of JS work that day!)... however, it’ll still error in Processing3 regardless as per @Mark above.

                          Dear @Marci,

                          As it says in Step 2 of the second tutorial you cannot use Processing v3, you must use Processing v2.2.1\. To wit:
                          ![](http://troikatronix.com/tt-images/tutorials/common/caution.png) **IMPORTANT!** You must install Processing v2.2.1 because SimpleOpenNI has not been updated to support the latest version of Processing!
                          So please try v2.2.1 and let us know how it goes.
                          Best Wishes,

                            After doing the changes.. it worked, my mac recognizes now the kinect device. Thank you!!

                            Is not in this area of the forum but as it seems I'm enjoying this program. is there a site or a place where I can get more tutorials besides the basic 13 episode form youtube??

                            Once again thank you for your help and such prompt response.

                                I think the confusion is the word regardless. It sounds like regardless what Mark said. Better would have been: it’ll still error in Processing3 as per @Mark above.

                                  Sorry, I thought you were the original user who had the problem (i.e., @Bunker) That's why I addressed you in the way I did. Sorry for the confusion and thanks for the update to the code. ;-)

                                    Would someone mind giving me some guidance? I've followed the instructions in the tutorial to the letter and am still getting nothing showing up in my canvas when I run the setup and an error message I don't even begin to understand in Processing. I'm using the 1414 model Kinect with a MBP Retina 15, bought last year. I understand that the usb3 port may be an issue, is there a work around? Am I screwed?b4ae38-screen-shot-2016-04-28-at-11.18.41-am.png

                                      Dear @George_A,

                                      From what I can see, there is a crash in the Java runtime environment when attempting to get a list of USB Devices. The crash is happening in libusb, which is the open source USB input/output library, in a call named darwin_get_device_list.
                                      What version of Mac OS are you using?
                                      I am unsure how to guide you on this. Many users are using these tools successfully. The only thing I could suggest is to somehow update libusb. The way to do that would be to install Homebrew (see [here](http://brew.sh)) and then enter the command line in Apple's "Terminal" program:
                                      brew install libusb
                                      I guess that's the only thing I can suggest here as a possible solution.
                                      Best Wishes,
                                      Mark

                                        Wandering off on a tangent... a tip for Kinect concept development work based on some playing around this weekend: Get some Lego, some of these: https://www.ebay.co.uk/ulk/itm/121953917174, and apply some judicious use of gaffa tape and scalextric cars & track... ;) Start small scale in your studio / kitchen, then scale up. Much easier than leaping about in front of camera / directing small child or significant other... and you can map the whole 'stage' with a single Kinect and projector. Allows for small scale testing of scenarios. :D

                                          @george_a might also be worth removing and reinstalling latest JRE to see if it has any impact... I'm running v8... you look to still be on v7.
