Visual displays play the key-role in almost every human-controlled system. In the process of development of such systems industrial designers need to design legible visual displays in ergonomic sense.
Readability of visual display can be affected by many factors including its position, the size of graphic details and also by visual defects of a man. At recent time it is possible to get some of visual displays properties using a computational modelling. The modelling is applicable, for example, to used font size or to the speed of movable parts of display determination ([3], [8], [9]). But computational models cannot involve all the substantial factors, which have an indispensable effect to the readability of visual displays, especially more complex factors. Position of stimulus created by a visual display on the humane retina affects an ability of recognizing the shape, the colour and the movement, for example. This and similar factors can be taken into account by knowledge modelling, by an expert system. The intersection of these two types of modelling - the computational modelling and the knowledge modelling - can be termed as a hybrid modelling.
This paper is concerned with design of an expert system which is suitable for integration into the hybrid model. and Obsahuje seznam literatury
