Calibrating MyTobii for each user is necessary in order to teach the system the characteristics of each user's eyes.
The settings for this can be found under the Calibration tab in the advanced settings.
This tab includes settings for size, speed and color of calibration dots as well as tools for inspecting and managing calibrations.
To a large extent, calibrating MyTobii is an automated process. By clicking the Calibrate button either in the eye controlled basic settings or under the calibration tab in the advanced settings, a calibration consisting of a pulsating circle moving over the screen is started. During calibration the user follows the circle across the screen focusing on the black dot in the middle of the circle.
