Most of them have no concept of design basics such as visual balance or rhythm. In this paper, we attempt to synthesize the guidelines and empirical data related to the formatting of screen layouts into a well\-defined model. Fourteen aesthetic characteristics have been selected for that purpose. The results of our exercise suggest that these characteristics are important to prospective viewers."]
