VISUAL FATIGUE MEASUREMENT DEVICE AND METHOD THROUGH BRAIN WAVE VARIATION ANALYSIS INCLUDING A BRAIN WAVE SENSOR MODULE ANALYSIS IS THE MEASUREMENT DEVICE AND METHOD INCLUDING THE BRAIN WAVE SENSOR MODULE

摘要

PURPOSE: Visual fatigue measurement device and method are provided to implement objective measurement by including a 3-D display.;CONSTITUTION: A brain wave measurement unit(120) measures brain wave. A fast Fourier transform unit(130) transforms the brain wave from a time domain to a frequency domain. A main control unit(110) extracts α-wave and β-wave in a specific frequency range from brain wave of the frequency range. The main control unit extracts power of the α-wave and power of the β-wave. A visual fatigue index calculation unit calculates a VFI(Visual Fatigue Index).;COPYRIGHT KIPO 2013;[Reference numerals] (100) Visual fatigue measurement device; (110) Main control unit; (120) Brain wave measurement unit; (130) Fast Fourier transform unit; (140) Α-wave rate calculating unit; (150) Β-wave rate calculating unit; (160) Visual fatigue index calculating unit; (170) Memory unit; (180) Display unit
