i got laser-guided-bombed
From the receiving end, let me say that shining a laser pointer at a student is not an effective way to call him/her. It's not like shining a torchlight, a laser beam is narrow. Even if the lecturer was shining it onto my white shirt, I wouldn't have noticed it unless I lower my head and look at my own shirt. What for during a lecture do I look at my own shirt!? So now you know, those scenes in movies where someone realized he was being aimed left right centre, it's exaggerated.
Pointing at the eyes is a no-no, although it can catch the target's attention. Being a class 2 laser product, the beam from a laser pointer can still damage your retina. I hate it when lecturers sweep their laser pointer across the lecture theatre like spraying a machine gun.
Oh and in the military, special forces point laser beam at the target to guide the air strike.
I walked out of the lecture theatre in one piece.
