I remember being apart of the initial beta test for OnLive about a decade ago. At the time the idea of streaming games was pretty exciting, but at the end of the day the technology just wasn't there.

Clearly companies right now think it's the future, since Microsoft, Sony, and even Nintendo, in some aspects, are investing in it. The technology, however, is really still not where it needs to be and I'm not sure if it ever will be. Latency is just a facet of how the internet works right now and the laws of physics. People put up with it for online multiplayer games, but I'm not sure if anyone is willing to put up with it 100% of the time.

This might be a thing in the far flung future, maybe, but not now.

@KBFloYd: I agree will all of these. I'd also like to add that if you don't want to spend a lot of money for a pro controller (they are about $60 USD) then the HORIPAD for Nintendo Switch are a good alternative. They are wired and lack the RFID support but for under $20 USD they are in my opinion just as comfortable as the pro controller and they are licensed by Nintendo. They also have a cool swappable d-pad that can let you physically switch between connected and four separate buttons for the directional controls. If you really want wireless controllers, the PowerA series are also a good choice, slightly cheaper than the official Nintendo pro controllers, and have some pretty cool designs.

I'm not sure what the blue screen is, but the joystick on the right is an "AbleNet Rock Adapted Joy Stick" as seen at https://www.rehabmart.com/product/rock-adapted-joystick-34709.html. It is a pediatric assistance device intended for use with special needs children. It essentially emulates a mouse in a fashion suited for uses where physical exertion of an actual mouse would be too exhaustive.

If you purchased these products together, I think it would be safe to assume that the screen is also some form of pediatric device. I'm not sure though what it's functionality would be as it looks like a regular monitor to me. Do the devices work, can you power them on? That might be one way to tell what they are supposed to be used for.
