How to pick points in RVIZ with a joystick?
I'd like to pick points (publish points) in RVIZ by using a joystick as well as interact with markers. There are a lot of ubuntu hacks out there but I see a lot of restrictions like they need to run in XWindows, etc. Has anyone seen or tried to do something like this?
I'm running hydro on Ubuntu 12.04.
Cheers

I don't know anything direct, but have you considered writing a simple interactive markers node that is movable by a joystick?

My need to interact with markers is just with a button marker actually and not to move them. My goal is to use the joystick to select the proper button. My physical environment is one that is not good for a mouse.

Do you need anything specifi that is not achievable with subscribing to joy messages and sending markers depending on that? Maybe you can give a concrete example.

Thanks for the idea. I don't fully understand the capability of joy, so I will look into that now. I use RVIZ to visualize a 3D point cloud scene from the Kinect. I then need to pick 3 points from the scene that get used in another node with ICP.

Can you describe how you'd want to do that with a joystick?

I want the joystick to replace the mouse.

I´m trying to do exactly the same thing as you TFinleyosu (visualizing a 3D point cloud scene but from an Xtion) and I am also trying to replace the mouse with a joystick but I am not getting it to work. I am quite new to ROS. Would you please help me if you already got it work? Thanks.

It's been a while, but I did get it to work. The solution was not from Ros but with an Ubuntu package that turned a USB joystick into a mouse. I think it might simply be called Joy. Let me know if it works for you
