Ive transformed into the superhero and made my "hat" fly, but I cannot shoot the two different lasers as seen in the youtube video. What do I need to do??

Please help.

Here's the hints. See FAQ in Wiki also for some tips to improve the accuracy of pose detection.

(1) Wide Shot: Form "L" by lower arms. (right arm upright & left arm level.) 

(2) Emerium Beam (Yellow): Place both hands right front of forehead. Elbows should be wide open. Don't cover your head too much by your hands because the camera needs to know where your head is.

(2) Emerium Beam (Green): Keep left lower arm level in front of chest, and place left hand close to neck. Keep right hand lower than left.

Hi, ive tried the poses you refere to on the picture. this video is me trying to get them to work (i know it is low qual!) http://www.youtube.com/watch?v=BiBfHvR5VUM  
Maybe you can say what I am doing wrong. Or is it my GPU?

Martin, if this video captures your screen fairly correctly, it seems the frame rate is too low. This software is designed to work on higher frame rate such as 15 frames/sec at least, but your frame rate looks about one or two per second which would make the pose detection difficult. Perhaps you need another PC at higher performance.

The resaon is you need to stay on the same pose for several frames to trigger a power. It would be less than a half second if you had enough frame rate, but it could be several seconds at a low frame rate.

I may be able to make some code change this weekend to make it a little easier at a low frame rate. However, note that the beams would not look very neat at this frame rate anyway.

No that is just because it is a low qual video! just 2 sec. and I will upload a much better video! belive me...the framerate is accelent!

Hmm, if so, it is difficult to say... I think your pose is fine. (Only one thing -- use your left arm, not right arm, to fire Emerium Beam Green.) Thanks for showing me another video that captures the frame rate more accurately. It may give me some more idea.

Now I have looked at your video and, yes, you are correct. The frame rate is not an issue here.

One possibility I can think of is the difference in the size of the body. I tuned the pose detection parameters (like "your hand and your head must be within this distance") based on the size of my body (160cm tall). If your are a person much bigger than me, those parameters could be too small (severe) for you. I'm not sure, but just a possibility.

p.s. Note the pose detection is left-right sensitive.

ok that could maybe be it, since im 190 cm tall. Dammit ;-) I was very much looking forward to try it.

I will create a more "generous" version later and upload here so that you can try and prove this hypothesis. Thanks for your help and patience.

Martin, I created a "trigger happy" version with looser (maybe a little too loose) pose detection parameters for the experimental purpose. Please download the attachment, place it in the same directory as kinect-ultra.exe, and try it. Does it work?

If yes, also let me know how you feel with the pose detection. (e.g. a kind of OK, too loose, still difficult, it's a fun!, etc.) If no unfortunately, I would need to investigate some more.

Thanks!

Thanks for your feedback. I plan to add a feature to adjust the sensitivity by hitting some key.

I noticed that I had made the detection of Wideshot more strict than intended, so I fixed it also in 0.1e.
