2.4.5 Record Screen
2.4.5.1 Record Screen Purpose
The Record screen allows users to initiate and observe data collection. The user
can choose either a Gaze Cursor View (see Figure 2-7) or Plot View (see Figure
2-8) by toggling the “Plot View” button, or by pressing the G key.
The Gaze Cursor View plots the current gaze position of the participant in the
calibrated screen pixel coordinates. Any graphics drawn on the screen can be
used as a reference for the real-time gaze-position cursor. The Gaze Cursor
View is only useful when the EyeLink system’s built-in calibration routines have
been used for gaze position calculation. The Plot View displays the x and y data
traces as a function of time.
