The graphic is interesting because it involves angles and lengths. It seems like there's a lot that kids could play with.
- If a couch is positioned at exactly 9 ft from the TV, what size TV should you buy?
- If your couch is positioned at a different distance, what size TV should you buy to keep the same ratio?
- If you own a TV of a given size, how far away should you place your couch? Does it matter if the given size refers to the diagonal or the width?
- When the article says "the TV should fill 40 degrees of your field of vision" what percentage of your field of vision is this (you'd need to think about your peripheral vision)?
- THX and SMPTE recommend 40 degrees and 30 degrees respectively. How does this change the size TV you should buy? Or where you should put your couch if you have a specific size TV?
- This could easily be connected to costs
- Does it matter where a person sits on their couch? The diagram works from a person sitting in the middle of the couch. Will other people on the couch still have the TV fill 40 degrees (or 30 degrees) of their vision? How much more or less of your vision will the TV fill at different points along the couch?
- What do these distances and angles mean about where you should (or shouldn't) sit in a movie theater?
The article also includes a link to a chart that accounts for pixel resolution. I haven't looked at it closely, but I'd be interested in exploring the patterns in the table:
