Exam 13 Question 8

Hi everyone,

I don’t understand the question 8 of the Exam 13 can anybody explain me for dummies?

That’s the question:


The best way to explain it would be to imagine you have a piece of glass with a dot in the center and you just stick it on the front of a camera and BAM you have a UI. Or the way the question is stating it imagine you have a laser pointer in the camera shooting out from where the camera is facing. The dot you get on the screen would be where the laser is hitting the glass.

Just sort of rambled there but I think it gets the point across or maybe not
