1. A system comprising:
one or more processors; and
one or more non-transitory computer readable media comprising computer readable code executable by the one or more processors to:
present a user interface on a display of an electronic device;
detect, during presentation of the user interface, a calibration event;
in response to detecting the calibration event:
determine an interactive component displayed within the user interface, and
present a stimulus mark coincident with the interactive component;
determine a calibration pair comprising an uncalibrated gaze point at a screen location of the display and a screen location of the stimulus mark; and
modify a presentation of the stimulus mark.
