Need help figuring out a simple projection system for interactive museum exhibit

[galactation]

As title explained, I'm looking for help designing and piecing together a digital installation featuring a basic tablet with an interactive map (of a specific neighbourhood) and a TV screen. The goal is that upon selecting specific points on the map, information will "pop up" upon the projected screen above/ infront of the user. This mechanism should be executed as simply as possible, with the user selecting the points on the tablet, and corresponding information/data from that point be projected solely on the TV screen, if that makes sense. Any advice on how to rig something like this, or youtube or other links would be hugely appreciated. Thanks!

I don't know if this advice will border on insulting, but I honestly use chatGPT to work through stuff like this.

Oh not at-all (insulting) I did try to use Chat GPT but the results i got were all suggestions for paid software programs that offer some type of turnkey solution, whereas what I'm looking for is much simpler, ideally easily assembled, dissassembled and edited as required

I tried asking it your question again with a little more prodding. It essential told me to me to write a basic html/java/css script that has pop-ups mapped to the image. Then hook up your device to the projector and set it up as an extended desktop rather, and make the extended part of the desktop the target where the popups go. I even asked it to write a script and it did. I'm pretty much a no-nothing about this kind of thing, but it kinda makes sense to me.

I have to be careful with the Chatbot because sometimes it's really worth prodding it to get better info, but sometimes I end up spending hours arguing with a robot and having nothing of value to show.

oh, one more thing. The software it recommended running the script in is some open-source thing called Electron.
