I work in a research lab which has me working with computer vision. I figured out how to track circles, then I just calculate the dimensions of the face that gives me a “guesstimate” on where their eyes are on the page.

How did you track your iris movements?

Perhaps, however when I am bored, i’ll just go to “speed reading mode.” Essentially, I just gather facts and move on. I don’t try to visualize the information and add it to my mental palace so to speak.

I think it’s subjective, which is why other factors to determine interest are VERY useful. It helps with individual classification.

As you can see there was a dip in the interest at around 135 seconds. This was when my girlfriend walked into the room and asked me a question.

It does seem as though the largest indicator of whether a person enjoys a book is how much time they spend on a page.

This seems counter intuitive. Subjectively, when I’m really interested in something, I can fly through it, while I’ll keep getting distracted from a boring page and it’ll take forever to get through.
