Ever caught a basketball? (Lot of basketball noise in the US right now.)
Or a baseball?
Played any other sport with a moving ball?
Your brain takes about 1/10 of a second to construct a perception of reality.
At 10 MPH, a ball moves 14.67 feet, while your brain creates a perception of its original location.
How did you catch the ball with your hands and not your face?
Mark Changizi has an answer to that question in: Why do we see illusions?.
The question Mark does not address: How does that relate to topic maps?
I can answer that with another question:
Does your topic map application communicate via telepathy or does it have an interface?
If you said it has an interface, understanding/experimenting with human perception is an avenue to create a useful and popular topic map interface.
You can also use the “works for our developers” approach but I wouldn’t recommend it.
About Mark Changizi:
Mark Changizi is a theoretical neurobiologist aiming to grasp the ultimate foundations underlying why we think, feel, and see as we do. His research focuses on “why” questions, and he has made important discoveries such as why we see in color, why we see illusions, why we have forward-facing eyes, why the brain is structured as it is, why animals have as many limbs and fingers as they do, why the dictionary is organized as it is, why fingers get pruney when wet, and how we acquired writing, language, and music.
