The pursuit rotor task is a task used in common use in the mid 20th century which involved a participant trying to follow (pursue) a small disc on a rotating turntable. Original mechanical versions had typical rotation rates of 60 RPM, which is probably too fast for mouse-controlled versions. The PEBL version offers a simple version with multiple trials and controllable parameters that can be used as a test of hand-eye coordination.
