Follow the dot.
Smooth pursuit is the ability to track a moving object with steady, controlled eye movements — not head movement. This exercise gives you a target that glides along a path so you can practice keeping your eyes locked onto it.
Optional: press and hold the dot with your mouse or finger while your eyes track it, to see an engagement/tracking score at the end. Skip this and just follow along with your eyes if you prefer — that's the real exercise.

The science behind this
Smooth pursuit is the slow, continuous eye movement that keeps a moving target locked on the fovea — distinct from the jumps of saccades. It's driven by continuous visual-motion feedback and typically tracks smoothly up to about 30°/second before corrective "catch-up" saccades appear.
Well-controlled pursuit supports tracking moving objects in sport, driving, and daily life, and it's a common target in vision therapy and concussion or vestibular rehabilitation. Following a predictable path builds smooth, sustained control.
What it trains
- Smooth, continuous tracking of a moving target
- Reducing intrusive catch-up saccades
Limitations
- The optional cursor score is an engagement proxy — real pursuit needs no mouse and is graded by an examiner or eye tracker.
