Abstract: The movement of a phone in an environment with different brightness, makes the luminance prediction challenging. The
ambient light sensor takes time to modify the brightness of the screen based on the environment it is placed in. This
causes an unsatisfactory user experience and delays in adjustment of the screen brightness. In this research, a method is
proposed for enhancing the prediction of luminance using accelerometer, gyroscope and speed measurement technique.
The speed of the phone is identified using Sum-of-Sine parameters. The lux values are then fused with the accelerometer
and gyroscope data to present more accurate luminance values for the ALS based on the movement of the phone. An
investigation is made during the movement of the user in a standard lighting environment. This enhances the user
experience and improves the screen brightness precision. The accuracy has given an R-Square value of up to 0.97.
