Systems and methods of eye tracking calibration

A non-transitory computer-readable storage medium comprising instructions executable by a processor, the instructions comprising instructions for:

• determining a sequence of characters, the determination of each character in the sequence comprising:
• displaying a plurality of moving objects on a display of a computing device, each of the moving objects moving along one of a plurality of object paths and corresponding to a respective single alphanumeric character,
• capturing images of at least one eye of a user while the plurality of moving objects are displayed,
• while the plurality of moving objects are displayed, determining, based on the images, eye movement information associated with the user, the eye movement information indicating eye movement of one or more eye features associated with at least one eye of the user,
• determining that a path of the plurality of object paths matches the eye movement information,
• identifying a moving object of the plurality of moving objects, the identified moving object moving along the matching object path, and
• appending a single alphanumeric character corresponding to the identified moving object to the sequence of characters;
• determining whether the sequence of characters matches a login sequence of the user;
• and
• responsive to a determination that the sequence of characters matches the login sequence of the user, granting access to an account of the user.

A system comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium comprising instructions executable by the processor, the instructions when executed by the processor causing the processor to perform steps including:
• determining a sequence of characters, the determination of each character in the sequence comprising:
• displaying a plurality of moving objects on a display of a computing device, each of the moving objects moving along one of a plurality of object paths and corresponding to a respective single alphanumeric character,
• capturing images of at least one eye of a user while the plurality of moving objects are displayed,
• while the plurality of moving objects are displayed, determining, based on the images, eye movement information associated with the user, the eye movement information indicating eye movement of one or more eye features associated with at least one eye of the user,
• determining that a path of the plurality of object paths matches the eye movement information,
• identifying a moving object of the plurality of moving objects, the identified moving object moving along the matching object path, and
• appending a single alphanumeric character corresponding to the identified moving object to the sequence of characters;
• determining whether the sequence of characters matches a login sequence of the user;
• and
• responsive to a determination that the sequence of characters matches the login sequence of the user, granting access to an account of the user.
