Enabling computer systems to recognize human facial expressions is a challenging research problem with many applications in behavioral science, medicine, security, and human-machine interaction. Instead of being another approach to automatic detection of prototypic facial expressions of emotion, this work attempts to analyze subtle changes in facial behavior by recognizing facial action units (AU, i.e. atomic facial signals) that produce expressions. This work proposes AU recognition based upon multilevel motion history images (MMHI), which can be seen as an extension to temporal templates introduced by Bobick and Davis. By recording motion history at multiple time Intervals (i.e., multilevel MHI) instead of recording it once for the entire image sequence, we overcome the problem of self-occlusion which is inherent to temporal templates original definition. For automatic classification of an input MMHI-represented face video in terms of 21 AU classes, two approaches are compared: a sparse network of Winnows (SNoW) and a standard kNearest neighbour (kNN) classifier. The system was tested on two different databases, the MMI-Face-DB developed by the authors and the Cohn-Kanade face database.

Interviews of twenty-six Industrial Engineering students and graduates were conducted during the first year of a three year study of the unexpected attainment of gender parity in the School of Industrial Engineering at the University of Oklahoma (OU). An analysis of the pattern of participant responses gives insight into industrial engineering (IE) student perceptions of IE. The perceptions were grouped into three broad themes: Career Profile, Discipline Profile, and Discipline Meta-Profile. The Career Profile includes the availability of multiple career paths and flexible careers in this discipline in addition to the potential for the attainment of status through entry into management. People-oriented, broad, and systems-oriented are terms that were used to describe the Discipline Profile. Discipline Meta-Profile is used to describe the participant's perception of other people's perceptions of industrial engineering (i.e. what IE students think other people think). These participants felt that other engineers think of IE as easy, or "imaginary" engineering. The participants also thought that the discipline is invisible, even to other engineers. While the meta-perception of IE might seem to be problematic for the discipline, many of the participants reject the meta-perception. Some participants recognized that IE's focus on people and systems is simply different than other engineering disciplines, not necessarily easier. Other participants felt the potential to enter into management outweighed the discipline meta-perception. One student summarized the response particularly well when he noted that IE is "inviteful" engineering.

Interactive plush toys, such as ActiMates Barney, raise new ethical concerns that we as HCI professionals need to address and understand. This panel is designed to bring those concerns to the forefront and allow panelists and audience members to debate key issues. The panel includes people with expertise in creating interactive plush toys, creating software for children, and investigating ethical issues of technology.

Hybrid simulation includes both functional computer software models and actual hardware subsystems operating as an integrated whole. A ''hot test bed'' or a ''hybrid simulator-emulator'' enables design engineers to evaluate conceptual models in a more realistic real-lime context, but places increased cognitive demands on the designer. This paper describes an architecture, and results from a prototype implementation, for a design decision support system to allow a designer to make more productive and cost effective use of a test bed system.
User modeling means acquiring, representing and managing assumptions about users of software systems. Inference processes as part of the representation component can be used to extend the base of assumptions, thus sup...

Natural language generation (NLG) is a subfield of natural language processing (NLP) that is often characterized as the study of automatically converting non-linguistic representations (e.g., from databases or other knowledge sources) into coherent natural language text. In recent years the field has evolved substantially. Perhaps the most important new development is the current emphasis on data-oriented methods and empirical evaluation. Progress in related areas such as machine translation, dialogue system design and automatic text summarization and the resulting awareness of the importance of language generation, the increasing availability of suitable corpora in recent years, and the organization of shared tasks for NLG, where different teams of researchers develop and evaluate their algorithms on a shared, held out data set have had a considerable impact on the field, and this book offers the first comprehensive overview of recent empirically oriented NLG research.

This book constitutes the refereed proceedings of the Third International Conference on Social Robotics, ICSR 2011, held in Amsterdam, The Netherlands, in November 2011. The 23 revised full papers were carefully selected during two rounds of reviewing and improvement from 51 submissions. The papers are organized in topical sections on social interaction with robots; nonverbal interaction with social robots; robots in society; social robots in education; affective interaction with social robots; robots in the home.
