Motion Detector asks you to spot which element in a scene is moving, or when motion starts. Human vision has dedicated motion sensitivity that works faster than shape recognition — you often detect that something moved well before you can say what it was.
A scene appears, mostly static.
Watch for the element that starts moving.
Click it as soon as you detect the motion.
Both detection speed and accuracy are scored.
Motion gets subtler as rounds progress.
Motion detection in the visual periphery. Peripheral vision resolves detail poorly but detects movement well, which is why looking slightly away from where you expect movement can help.
Look at the centre and use peripheral vision. The periphery is genuinely better at motion than the fovea.
Soften your focus. Hard fixation suppresses the very sensitivity you need.
Do not scan around. Scanning creates self-generated motion that masks the real thing.
Stay still yourself. Head movement makes everything appear to move.
The retina's periphery is dominated by cells that respond to change rather than to detail. That is why something moving at the edge of vision grabs your attention before you can identify it.
No — fixating centrally and letting the periphery do the detecting is faster, which surprises most people.
Yes, the motion becomes slower and smaller.
They both use motion, but this is detection and that is tracking. Different tasks.
