Hi everybody

1.-I have installed sudo apt-get install ros-groovy-openni-tracker

2.-I have also installed NiTE v1.5.2.21 Linux-x86, then I have extracted the file to my Downloads directory, and I did the following:

cd ~/Downloads/NITE-Bin-Dev-Linux-x64-v1.5.2.21

sudo ./install.sh

Then cd /Samples/Bin/x86-Release$ ./Sample-Players and works fine.

3.-Then I run rosrun openni_tracker openni_tracker

4.- I stand in front of the Xtion pro and I get the following

New User 1 Calibration started for user 1 Calibration complete, start tracking user 1

But I cannot see any image, nothing

Any ideas

As per OpenNI tracker package description: The tracker publishes the acquired poses of different joints like head, neck, ... to the tf tree.

From here, they can be accessed in different manners:

For visualization, you can view them e.g. in RViz as you pointed out in your answer.
If you want to access the transformations from code, have a look at the tf Tutorials.

Well, I found out that openni_tracker doesn't display anything. Instead, all the frames can be seen in rviz under the fixed frame /camera_link an a transform visualization.
