Who develops software for ultra short throw projectors?

Question

Software and Internet Services

Tell me, please, if I need to develop a program for an ultra short throw projector, what specialists should I look for? Can he recognize what I write on the wall? And if I need, as if I click on some button or object on the image. I don't know the names of programmers who develop such software. That is, you need to develop an application that, when output through the projector, will be available for user interaction.
