Successfully completing continuous tasks with manual or muscle interfaces is crucial for many tasks including cursor navigation. While a user may intend to follow a desired reference path (dotted red line) with user intent (dotted red arrows), unexpected disturbances (sudden change in cursor position between the two blue circles) introduce errors that must be corrected with error correction (solid blue arrows). The user input (mouse position) combines user intent and error correction and maps to the cursor position on the screen (blue solid line).
