But why would it cost hundreds or dollars? I can see why a DIY solution might, but if there's demand for it, surely it can be packaged as a plug-and-play device, and manufactured at scale for a lot less?
Camera + beefy computer + input device, maybe an external motor based thing if controllers are crypto locked by manufacturers in the console case.
Even if you made a specialized item it would still cost a lot mostly due to the ML requirements. Maybe smartphone + a specialized input device would reduce the 'cost', but you still need to buy a several hundred dollar cell phone.
I can't see that taking off at scale, but certainly in the semipro level it would be used.
Besides, I know like 90% of cheaters are 14 year old kids who used the first google result because it's so easy to. Any resistance and that'll stop a majority
