Určení vhodné pozorovací vzdálenosti pro displeje s ohledem na fyziologii oka

Abstract

The aim of this bachelor thesis is to determine suitable viewing distance for various display sizes and resolutions with respect to the physiology and optical properties of the eye. In the first part the physiology and optical eye system are described, including a description of the visual field and the most suitable viewing angles for watching displays. In the next part the principles of today the most used displays are described and also their properties and specifications. Mathematical calculations are made for three kinds of activities. The first activity includes processing of computer graphics in case of need to distinguish individual pixels. Further are made calculations for word processing. And the third part includes calculations for watching the television with the goal of determination minimal and maximal range of distances, so that the eye would not be able to distinguish individual pixels. The last part is focused on the comparison of calculated values to the values given by the producers and creation of a program to calculate the distance based on the input parameters of the display.
