navigating with a controller and not screen topic

I would essentially like to buy an mhl cable and hook an old phone to the tv and use it as a media box. I would like to be able to sit on the bed and control everything. at minimum i'd like to be able to watch movies but I would also love to be able to do all the normal things i can do.

I've seen plenty of mouse and keyboard setups for android, but never a controller setup where they can navigate through everything.

It would be really cool to be able to usehttp://www.androidauthority.com/mad-catz-surfr-lynx3-controllers-mwc-2015-590340/ the one with the keyboard then I could actually type simple things with it if i wanted to watch youtube on the tv or something.

I guess I'm just asking is it possible to be able to leave the phone next to the tv and use the controller for all my input? does it put a mouse on screen that i can move with the control sticks/ d pad or does it do something else?? or does this option not even exist lol
