1. A wearable system for eye tracking calibration, the wearable system comprising:
a display configured to display an eye calibration target to a user;
a hardware processor in communication with a non-transitory memory and a display system, the hardware processor programmed to:
cause the display to display the eye calibration target at a first target location;
identify a second target location different from the first target location;
determine a distance between the first target location and a second target location;
determine a total time to move the eye calibration target from the first target location to the second target location;
calculate a target movement speed curve based on the total time, the target movement speed curve being an S-curve; and
move the eye calibration target over the total time according to the target movement speed curve.
