The fourth international workshop on Perceptual Quality of Systems aims to bring together leading professionals and scientists from different fields that are all related to perceptual quality. Supported by ISCA and the European COST action Qualinet, this event will serve as a forum for an interdisciplinary exchange of ideas between both academic and industrial researchers working on different aspects of perceptual quality of systems. Inaugurated in Herne/Mont Cenis (2003) and continued in Berlin (2006) and Bautzen (2010), PQS 2013 will be held in Vienna, Austria.

User perceived quality of technical systems is grounded on human experience and hence a highly complex and multidimensional phenomenon. Thus, any approach to quality assessment and prediction has to take the relevant human perception and judgment factors into account, an issue that has been addressed by a number of scientific disciplines including psychophysics, cognitive psychology, speech and audiovisual quality assessment, human computer interaction (HCI), usability and user experience research, and Quality of Experience (QoE).

Authors are invited to submit extended paper abstracts (1.5-2 pages) until April 11, 2013 (extended deadline) using the guidelines and tools available under the following link:
