Paired comparison as a method for measuring emotions

Due to the growing complexity and functionality of multimedia systems, quality evaluation becomes a cross-disciplinary task, taking technology-centric assessment, as well as human factors into account. Undoubtedly, emotions induced during perception, have a reasonably high influence on the experienced quality. Therefore the assessment of users' affective state is of great interest for development and improvement of multimedia systems. In this work problems of common assessment methods as well as newly applied methods in emotional research will be displayed. Direct comparison of stimuli as a method intended for faster and easier assessment of emotions is investigated and compared to previous work. The results of the investigation showed that paired comparison seems inadequate to assess multidimensional items/problems, which often occur in multi-media applications.
