Night Vision Function
I don't know how much it might add to the production cost, and therefore the final product cost, but I like that Occulus Rift S doesn't use lasers, or mounted things, extra boxes, or whatever to track. I like that it is just the goggles and controllers, and poof tracking and working.
However, I hate that it complains there's not enough light to track properly. I understand why there isn't, it's using cameras to track, but I hate that it can't track with dim lighting, or no lights at all.
I tend to use my Rift S at night, and I don't like having to light up the whole house to use it. If the cameras had night vision, I'm sure it would also require adding in at least one night vision laser, if not a few, so that it could work without lights, it would be very nice.
