Hi
I am not sure if this is the right Place to ask this question, but there is no board here on exploratory engineering.
Laser pointers are great for pointing out something if the spectators know the general direction they should be looking at. Lasers are better when it's dark than light since then you can see the beam more easily. Heck, during night the viewers may not even need to be told beforehand in which direction they should be looking since the beam is visible.
However, let's say I want to point at something very far away, and it's during the day. Let's say I have to point out a specific mountain peak or a specific window on a building. Heck, my hand is probably not steady enough, so I'll need a machine to do it for me.
What can I use to make the pointer? A really strong laser is probably not a good solution in this case. An AR headset With something like a video game HUD could work. However, I want to know what else can be used. I am not asking about something that is available off the shelf right now; I am rather just curious about how physics and Technology can be used to solve this particular problem.
