I am using hand detection of mit-ros-pkg. I have met 2 problems. My ubuntu 11.04 and ros electric.
1. The openni_kinect stacks of the ros installation works perfectly fine. But the demos doesn't. When launching hand_detector, I noticed that the process skeletal_tracker was always relaunching:

again and again! I have tried this method but doesn't work for me. http://answers.ros.org/question/9721/skeletal_tracker-crashes/
2.When I "roslaunch hand_interaction hand_detector.launch" . I can get the image in the Prime Sense User TRacker Viewer. But When I "rosrun rviz rviz -d $(rospack find hand_interaction)/config/handdetection.vcg" . The status of each list is OK except three "Point Cloud2" lists of which the topic is "camera/depth/points2", "/hand0_fullcloud" and "/hand1_fullcloud". Their status is warning! And there is no image showing on RViz. But when I changed "camera/depth/points2" to ""camera/depth/points". The status of that "Point Cloud2" become OK and I can get image on RViz exactly the image on Prime Sense. Is that just luck? And how can I solved the other two warnings! I want to realize the function of hand detection! I know maybe I explain the question not clearly, Some possible reasons cause this problem will be good enough! Thank you in advance! MORE INFORMATION: The Topics in all the three "warning" drop-down lists said "NO messages received" HELP!!!
Thank you in advance!!!!
