INTRODUCTION
Another aspect that needs to be noticed is that children and teenagers alike spend quite a number of hours playing video games
Children may keep on going over their limit that could eventually post significant health issues.
Symptoms include mood shifts, sleep dysregulation, inability to concentrate, appetite lost and among others

Analysis methods
(Alpha + Theta) / Beta ratio as a figure to measure fatigue.
Three kinds of EEG energy ratios (index ratio) : (α+θ)/β: (fatigue and drowsiness level) θ/α: Relaxation level (relaxation level) β/α: Awakening of standards (alertness level)

System architecture
Therefore, the aim of this system is to study how determine the state of fatigue during gaming through measurement, recording and analyzing the players’ EEG.
The algorithm to measure and determine fatigue has gone through several tests and evaluation thus providing an improved method of measuring fatigue.
Results are then displayed through a user friendly and informative GUI.
