Keep your mouse cursor as close as possible to the moving pink target for 20 seconds. Measures continuous visuomotor tracking accuracy.
Smooth pursuit is the name for the specific type of eye movement your eyes make when continuously tracking a moving object - distinct from the rapid, jumpy movements ("saccades") your eyes make when scanning a static scene. This free smooth pursuit tracking test measures how well your visual system coordinates with your motor system (moving the mouse) to keep pace with a continuously and unpredictably moving target.
Smooth pursuit ability is genuinely important in sports (following a ball through flight), driving (tracking a moving vehicle ahead), and any precision hand-eye task like surgery or piloting. Interestingly, smooth pursuit is also one of the few eye movements that's difficult to fake or perform without an actual moving target to follow - which makes it a useful clinical marker in some neurological assessments and a genuinely informative self-test of your visuomotor coordination.
Neurologists sometimes assess smooth pursuit quality as part of broader neurological exams, since disruptions to this eye movement pattern can indicate certain conditions. In sports science, smooth pursuit accuracy is studied in relation to batting, tennis returns, and goalkeeping performance - all tasks demanding continuous visual tracking of a fast-moving ball.
Jerky, oversized mouse movements overshoot the target - smooth, small adjustments track better.
Let your eyes lead the tracking, with your hand following - eye movement is naturally faster than hand movement.
Tennis, table tennis, and badminton all train this specific eye-hand coordination pathway.
Racquet sport players, gamers wanting to benchmark their tracking precision, and anyone curious about their baseline eye-hand coordination for tasks like driving, sports, or fine motor work will find this smooth pursuit test a quick, informative benchmark.
Smooth pursuit is generated by a completely different neural pathway than the eye movements used for reading or scanning. Where reading relies on quick jumps called saccades, tracking a moving object recruits the middle temporal (MT) and medial superior temporal (MST) areas of the visual cortex, which specialise in detecting motion direction and speed before feeding that signal to the muscles controlling your eyes. This is one of the few movements the human eye cannot perform accurately on command - try tracking an imaginary dot moving smoothly across a blank wall and your eyes will jump in small steps instead of gliding, because the system needs a genuine moving target to lock onto.
This test approximates that pathway using your mouse instead of your eyes, so the score reflects a combination of visual prediction and hand-motor execution rather than pure oculomotor control. That combination is actually closer to what real-world tasks demand: a batter tracking a pitch, a driver following the car ahead, or a surgeon guiding an instrument all rely on eye-hand coordination working together, not eye movement in isolation.
Unlike simple reaction time, smooth pursuit accuracy is sensitive to fatigue, screen distance, and even caffeine intake. Long sessions in front of a screen reduce blink rate and can cause the eyes to dry out, which measurably degrades tracking smoothness. If you notice your distance score creeping upward (worse) across repeated attempts in one sitting, it is often fatigue rather than a real skill decline - try resting for a minute and testing again on a fresh attempt to get a more representative baseline.
Outside of this benchmark, people improve real-world tracking with deliberately slow, repetitive drills - following a swinging pendulum, watching a slow-moving car from a stationary point, or the classic "pencil push-up" exercise used in vision therapy. If you enjoy this kind of continuous visual tracking, you may also want to try the Target Interception test, which swaps continuous following for a single precisely timed click, or Multi-Target Tracking, which adds divided attention on top of the tracking demand by asking you to follow several objects at once.
Smooth pursuit is continuous tracking of a moving object. Saccades are the rapid, discrete jumps your eyes make when scanning between fixed points - like reading a line of text.
Mouse-based tracking adds a small lag compared to pure eye tracking - the score is calibrated relative to typical mouse-tracking performance, not raw visual pursuit ability.
Yes, completely free with a 20-second test duration and instant scoring, no account needed.
Smooth pursuit is the ability of your eyes to continuously follow a moving object without jumping, unlike the rapid jumps (saccades) used to scan static scenes.
Smooth pursuit accuracy is used in clinical and even roadside sobriety assessments, since alcohol, fatigue, and certain neurological conditions disrupt it measurably.
Combining visual tracking with a synchronized mouse or finger movement, as this test does, closely mirrors the coordination needed in sports and precision tasks.
Yes, athletes who track fast-moving objects regularly, such as tennis or baseball players, tend to show superior smooth pursuit performance developed through practice.
