Well the OP talks about a fridge.

I think if anything it's even worse for tiny things with tiny screws.

What kind of floating hologram is there gonna be that's of any use, for something that has no schematic and the closest you have to a repair manual is some guy filming themselves taking apart some related product once?

It looks cool in a movie because it's a 20 second clip in which one connector gets plugged, and tens of person hours were spent on it by very talented people who know how to set up a scene that looks good and not just visually noisy.

I think he means repairs like washing machines, cars etc. It's all very well looking up videos or pics of how to repair stuff, but often the video isn't clear or fine quality enough

An overlaid graphic on whatever you were repairing would be fucking amazing for some of the stuff I do

Yes?

Having shit clearly labeled would be incredibly helpful.
