Depends on the mileage you get from it. I stopped using it quite quickly as I never found it to be as reliable as a button, more of a gimmick and I'm not short of buttons anyway. My experience: "Computer" -
Nothing. "Computer" -
Nothing. "COMMM-PPPUTTT-ERRRR" -
Yes Commander, "Gear Down" -
Nothing. "Gear Down" -
Landing Gear Deployed (about ruddy time....). Drove me nuts and no amount of speech recognition training helped, if anything it got worse the more I trained it. Who knows, it could very well have been my mic at fault (pre CV1) but no one ever complained about my mic quality in game.
I guess buttons once I get a stick. Hoping they add customizing screen positions!
I don't have a source but I'm sure I read the devs behind the UI placement in VR stated that the UI was positioned the way it was to make the best of what they had, moving the panels further away would cause clipping with the cockpit, making them larger was the same and moving them closer caused eye strain.
Personally, I think that if the 'disable UI Menus' button actually kept them disabled until you wanted to see them this wouldn't be a problem. Press a button, now your head tracked UI works, press it again and they stop appearing until you need them again. Unfortunately as soon as you enter or exit supercruise the UI returns to being on even if set to off - very annoying, although I did make a script to keep it off once.
The most reliable solution I found was to map the left & right UI panels to a rocker switch under my thumb on my throttle. Now they're off unless I want to see them and my view is uninterrupted in all craft but no 'look to activate' - to be honest I think I prefer it without 'look to activate' now and activating them is second nature just like looking at them, that's personal taste though.
