Controlling "Smart" appliances - advice on getting started?

I read the rules, and I think this is allowed, but i apologize if it is not.

I am not asking for you to do the work for me. I just hope someone can point me in the right direction.

I am an embedded HW/SW engineer, if that bit of info helps at all.

I want to make a tool (specifically for blind people) to replace the touchscreen with a physical button controller of sorts. I tried searching for similar projects, but I couldn't really find anything.

I dont want to exploit security vulnerabilities like buffer overflow or anything, I'm more interested in hardware modifications. But if push comes to shove... I might be interested in that.

If anyone knows the right tree for me to bark up, your input would be very appreciated.
