Projector (interactive - with touch input) - card - software?

Question

Software and Internet Services

Please tell me the software for solving the following problem:
a) there is a projector with interactive input (there is a sensor above the projection area that monitors the touch of the projection surface).
b) the projection should not go to a rectangular window - but to a figured map (well, a map of the region, for example) - accordingly, mask processing is needed - so that it does not shine outside ....
c) by touching the map in a certain place - launching specific content - BUT - content should still be "cut off by the mask" - the projection goes only to the area of ​​the figured map.
d) when displaying content in point C. - if we touch the surface with our hands - rollback to point B.
I thought about the "simple" option - map in HTML in the browser - almost suitable for processing clicks, but with media content - difficulties - mask impose?!
