The method further envisages: implementing a roll-compensation of the gyroscope signal (Gyro) as a function of the gravity vector (g) to determine a roll-compensated gyroscope signal (Gyro'); and generating the screen-frame displacement data based on the roll-compensated gyroscope signal (Gyro').",
