We present the results of an experimental study towards modeling the reader�s emotional state variations induced by the\r\ntypographic elements in electronic documents. Based on the dimensional theory of emotions we investigate how typographic\r\nelements, like font style (bold, italics, bold-italics) and font (type, size, color and background color), affect the reader�s\r\nemotional states, namely, Pleasure, Arousal, and Dominance (PAD). An experimental procedure was implemented conforming to\r\nInternational Affective Picture System guidelines and incorporating the Self-AssessmentManikin test. Thirty students participated\r\nin the experiment. The stimulus was a short paragraph of text for which any content, emotion, and/or domain dependent\r\ninformation was excluded. The Analysis of Variance revealed the dependency of (a) all the three emotional dimensions on font\r\nsize and font/background color combinations and (b) the Pleasure dimension on font type and font style. We introduce a set of\r\nmapping rules showing how PAD vary on the discrete values of font style and font type elements. Moreover, we introduce a set of\r\nequations describing the PAD dimensions� dependency on font size. This novel model can contribute to the automated reader�s\r\nemotional state extraction in order, for example, to enhance the acoustic rendition of the documents, utilizing text-to-speech\r\nsynthesis.
