This paper presents a visual acuity measurement system, AQUIR, which provides the functionality to generate customized visual acuity charts quantitatively. Visual chart is the basic measure to evaluate the visual acuity. With low variability, the traditional visual chart is inflexible and the same chart is used repeatedly to conduct vision assessment. AQUIR system implements a real-time solution and it can customize the visual acuity test book with more flexibility. The process customizes the background, races and reading habits. The adjustability of font sizes and word sparsity subdivides the diagnostic result levels. Besides traditional printed text version, the codebook can be displayed on back-illuminated electronic devices. It widens the application areas for the AQUIR system and transforms the traditional style of the visual acuity measurement system. The dynamic visual acuity codebook will facilitate the operating procedures of visual acuity measurement and improve the accuracy of diagnosis. By breaking through traditional technology, the flexibility and accuracy of visual acuity measurement is improved and reproduction of the technology on multimedia can be performed.
