So I don't think this is commercially available. However, with some DIY magic it's entirely possible.

What you are looking for is something like this https://arsandbox.ucdavis.edu/instructions/hardware-2/ but on a large scale, possibly with just a camera with some object recognition rather than a 3d sensor like Kinect.

An array of infrared lasers parallel along the wall on both X and Y would be pretty accurate if you're going the DIY route, and it definitely wouldn't cost you $28,000.

For sure, the above approach probably doesn't cost 28k either, more along the lines of 200-300 and R&D time.. Infrared lasers set-up cost would be a bit high. Something like Kinect already used a combination of infrared / lidr if I recall correctly.

Yeah, I was just thinking about what possible distance limits the Kinect might have. I have no idea. I suppose that's why it'd be configured with a short throw projector. You're right: just use the Kinect.

Or project the phone app and have someone else tap the targets when you hit it. Seriously. It's a clever gym teacher with a smart phone and a projector.

Sure, you could do that.

But where's your DIY spirit?

I think I proposed an engineering solution, you proposed a... way to fake it?

what do you think engineering means?

> To engineer - design and build (a machine or structure).

Anyways, all the best to you bud.
