I am often asked about the relation of video technology and viewer position and typically in two forms. First, how far away can a viewer be before they see a good image on a screen/tile/display? Or the opposite, I have a room that is this 17′ (5.2m), so what resolution or image density should I use in the design?
Well, the answer is possible to calculate, but first, you have to understand what a pixel is, what parts make it up, and the math that allows all the parts to be calculated. I am going to start a mini-series leading up to an article released in February tying this into how to calculate viewing distance using a technology-agnostic formula set based on human vision. So stay tuned! This series is going to change the way you think of video in today’s modern environment.
