Question 1

What is multiple object tracking (MOT)?

Accepted Answer

Multiple Object Tracking (MOT) is a cognitive task in which observers simultaneously track several independently moving targets among identical distractors. First described by Pylyshyn & Storm (1988), MOT research shows humans can reliably track 3–5 objects simultaneously, a limit tied to visual attention capacity.

Question 2

What is the Boids flocking algorithm?

Accepted Answer

Boids is a flocking simulation algorithm created by Craig Reynolds in 1987. It uses three simple rules — Separation, Alignment, and Cohesion — applied to each agent locally. The result is realistic group movement that emerges without any central control, similar to how birds flock or fish school.

Question 3

How many objects can humans track at once?

Accepted Answer

Research by Cavanagh & Alvarez (2005) found that visual working memory saturates around 3–4 objects. Speed, density, and occlusion all reduce tracking accuracy. Professional athletes, pilots, and surgeons train MOT-like skills to push beyond these natural limits.

Question 4
