CONTEMPORANEOUSLY CALIBRATING A GAZE-TRACKING SYSTEM AND AUTHORIZING ACCESS TO ANOTHER SYSTEM

A system for contemporaneously calibrating a gaze-tracking system and authorizing access to a first other system can include a processor and a memory. The memory can store a preliminary operations module, an authorization module, and a gaze-tracking module. The preliminary operations module can include instructions to compare a trajectory, of a point of gaze of an eye, with a pattern associated both with a calibration of the gaze-tracking system and with a first authorization process, that excludes an iris recognition process, for the first other system. The authorization module can include instructions to cause an access to the first other system to be authorized. The gaze-tracking module can include instructions to: (1) cause the gaze-tracking system to be calibrated and (2) cause, in response to the gaze-tracking system being calibrated, the gaze-tracking system to be configured to be a user interface for a second other system.
