Visualization System for Experiencing Visual Functions of Elderly People by Image Processing

Abstract

In recent years, the use of display systems such as car navigation systems and in-car traffic information terminals has been increasing. Furthermore, the elderly population is also rapidly increasing. To improve visibility of in-car display systems for drivers, it is indispensable to design a display system from which young designers can experience the visual performance of older people. This paper describes a system to simulate the visual functions and aging of elderly people. The proposed system is composed of image input devices, a computer and a display device. The method of this system is implemented by image processing techniques, which are intended to visualize three human vision properties; spatial response, spectral transmittance of crystalline lens and accommodation. We have concluded that this system plays an important role in understanding the virtual driving view of elderly people.
