Abstract

Visual field luminance determines the optimum display luminance necessary for adequate visibility. In this study, we developed a method that estimates the luminance level of a driver's visual field using an illuminance sensor and investigated its actual characteristics. We then simulated the visual field of a driver's seat environment under experimental conditions. In our experiments, test subjects evaluated the optimum display luminance of a car-navigation system under static conditions, with variations added to simulate time of day and weather. As a result, we obtained an equation that predicts the adequate display luminance level based on driver's visual field luminance level.
