content: So if you read airframe you will get itWhat is a easy way to interface a instrument to some kind of heads up display?Other then doing alot of seriously complicated stuff, I thought one way would be to make a adapter that fits over a instrument and to put some kind of wireless camera on it (like a go pro connected to a scope-cam adapter of old) that connects to smart glasses so you can put a over lay of the instrument in the corner of your vision while you work so you can focus on holding the probes and reading the PCB in the interests of speed and safety (so you don't need complicated jigs or to hold steady while you look away).Is there a cheap system of some kind that you could set up this system in so that you can adjust the transparency of the video display, where the display is in your field of vision and still be able to work? Maybe with a voice activated command to take pictures of the HUD or even what your vision looks like?It should increase speed, safety and documentation all in one step. I don't follow the high end smart gadgets field at all because i always thought they were useless *unless its for land navigation, it was pretty cool in the new mission impossible movie*How would the various commercial options look like? It would be especially useful with an oscilloscope that has a short ground connection to eliminate ringing. (this seems like a two handed job where you use isolated tweezers to stabilize your ground bayonet lug and the other hand to hold the probe, otherwise you pretty much need to solder in a little coil adapter to stick your probe into or some kind of precise helping hands. Or if you are working upside down, on a ladder, etc.

content: i meant a commercial units that engineered. Can google glasses connect to a go pro or something like that?

content: I see. I thought about those transparent monitors, I think they could have interesting applications. Like attaching one to an articulated arm on your bench and using it between you and whatever you're working on. Feeding them with a video signal from any camera or computer.I don't know much about Google glasses, I actually thought they abandoned the project but I'm not too sure.This could work for you:https://www.vuzix.com/products/blade-smart-glassesSeems they have an app that allows to connect to a phone's camera. I don't know if you can feed them a video input directly (or if any AR glasses do for that matter), so you'd still be dependent on a smartphone or tablet for the video streaming I guess.

content: that would be cool for a bench top if you make a good arm for it but I think you would need a stream from a camera looking at an instrument display for it to be useful in most cases. But if you had a buncha GPIB hookups for old instruments to go into computers like a spectrum analyzer it would be cool.For older people an overlay over a benchtop magnifier might be useful too.But I expect the arm would need to be really good to make it work well. It would not be worth the money if it did not position exactly where you put it. I kind of wondered if you can make hydraulic cylinders that provide high friction with some kinda active system that increases friction or something after you position it and push a button...IMO otherwise its going to be a ware nightmare. and it needs to move soft to fit the theme of a electronics laboratory with high end equipment.

content: well if you have GPIB, / ethernet, most instruments will either let you pull screenshots, or relevant parameters,Its like checking a circuit, if you dont have to look down at the display every time, its much faster.Apparenetly a lot of hobbiests use a 0.54 inch OLED display and a mirror off a glasses arm, so you can see the reflectionMaybe not the exact model, but if I was going to try it, I would probably start with something like this.https://www.adafruit.com/product/661
