I am working in an industrial setting, where I would like to have a GUI application on a touch display, running under Ubuntu 22.04. I want users to interact with that GUI without having total access to the system. I am wondering, how this is typically handled.
The system runs a python script, which operates a machine. For manual operators working in the facility, the touch display should give some functionality to start and stop the system, adapt config, etc. What I do not want to allow is for operators to have full access to the operation system, as well as my python programs. My program includes a FastAPI, so external programs could communicate with my Python program.
Hence, I would like to figure out, how to have such interactive GUIs. I know that many machine manufacturers have such solutions, but they commonly don't use a "normal" PC.
I have done some search, but somehow struggle to find the right words to explain, what I need. I assume there is technical nomenclature for this topic.
Thanks in advance.
