If you intend designing your own control system then best of luck as its extremely complex if you intend it to be in any way safe and controllable.

And its just easier to use say a complete r-net powerchair with an IO unit or a Omni device designed to accept external dc voltage swing input for alternate control Since that already exists with a decade of development work aleady done.
I'll buy that, and even brain controlled speech as long as there's a backup for when it isn't working. BUT a brain-controlled wheelchair (or any wheelchair control that depends on a PC operating system, or, heaven forbid, the cloud ---- NO. The safety issues with that are scary. Consider faults in two circumstances: going when you should be stopped (e.g. waiting for traffic to clear before crossing a street), and stopping when you should be going (e.g. half way across an intersection).Brain controlled doors, lights, heating, typing, etc would all be marvelous!

I completely agree with this, I'm amazed how many people use cloud based systems in home automation etc. My Home Assistant install does not require any cloud access though I can use a VPN to access it whilst away from home. You would have to be a bit soft in the head to rely on any system that needs on an internet connection to function without a local option ( in my opinion ). I'm even more concerned about the headlong dash to connect cars to the cloud, it's positively dystopian and as for drive by wire, don't get me started , pass my tin hat.

There is NO SUCH THING as "CLOUD"!
Phones have about 250GB of storage anyway.
I should let my students interact with wheelchair users and professionals who tailor wheelchairs to the user's needs.

I dont know who gavin is but I suspect the "professionals" and end users will get you nowhere fast.
