  • The Faces of Engagement: Automatic Recognition of Student Engagementfrom Facial ExpressionsJune 20, 2014 - 2:47 pm

    Student engagement is a key concept in contemporary education, where it is valued as a goal in its own right. In this paper we explore approaches for automatic recognition of engagement from students’ facial expressions. We studied whether human observers can reliably judge engagement from the face; analyzed the signals observers use to make these […]

  • Understanding online reading through the eyes of first and second language readers: An exploratory studyJanuary 14, 2014 - 1:34 pm

    Abstract Utilizing eye-tracking technology and focusing on the “rapid”, “purposeful” and “comprehending” attributes of fluent reading, this study investigated first language (L1) and second language (L2) readers’ online reading patterns and comprehension. Eye movement data from nine L1 readers and nine L2 readers were collected, analyzed and compared. Post-experiment interviews were conducted to obtain demographic […]

  • Home Alone: Social Robots for Digital Ethnography of Toddler BehaviorJune 5, 2013 - 4:00 pm

    Abstract We describe the results of a field study in which the social robot RUBI-5, was left alone for a 28 day period to interact autonomously with 16 toddlers at an Early Childhood Education Center. The study is part of the RUBI project, which started in 2004 with the goal of exploring the potential of […]

  • Towards social robots: Automatic evaluation of human-robot interaction by face detection and expression classificationJune 5, 2013 - 3:32 pm

    Abstract Computer animated agents and robots bring a social dimension to hu- man computer interaction and force us to think in new ways about how computers could be used in daily life. Face to face communication is a real-time process operating at a time scale of less than a second. In this paper we present […]

  • Automatic Recognition of Facial Actions in Spontaneous ExpressionsJune 5, 2013 - 2:59 pm

    Abstract Spontaneous facial expressions differ from posed expressions in both which muscles are moved, and in the dynamics of the movement. Advances in the field of automatic facial expression measurement will require development and assessment on spontaneous behavior. Here we present preliminary results on a task of facial action detection in spontaneous facial expressions. We […]

  • Inscrutable games? Facial expressions predict economic behaviorJune 1, 2013 - 1:10 pm

    Abstract Neuroscientific and behavioral evidence shows that when subjects are engaged in simple economic games, they pay attention to the face of their opponents. Is this a good idea? Does the face of a decision-maker contain information about his strategy space? We tested this hypothesis by modeling facial expressions of subjects playing the Ultimatum Game.

  • The Computer Expression Recognition Toolbox (CERT)June 1, 2013 - 1:05 pm

    Abstract We present the Computer Expression Recognition Toolbox (CERT), a software tool for fully automatic real-time facial expression recognition, and officially release it for free academic use. CERT can automatically code the intensity of 19 different facial actions from the Facial Action Unit Coding System (FACS) and 6 different protoypical facial expressions. It also estimates […]

  • Towards an Optimal Affect-Sensitive Instructional System of Cognitive SkillsJune 1, 2013 - 12:18 pm

    Abstract While great strides have been made in computer vision toward automatically recognizing human affective states, much less is known about how to utilize these state esti- mates in intelligent systems. For the case of intelligent tu- toring systems (ITS) in particular, there is yet no consen- sus whether responsiveness to students’ affect will result […]

  • Exploring the Facial Expression Perception-Production Link Using Real-time Automated Facial Expression RecognitionJune 1, 2013 - 12:14 pm

    Abstract Motor production may play an important role in learning to recognize facial expressions. The present study explores the influence of facial production training on the perception of facial expressions by em- ploying a novel production training intervention built on feedback from automated facial expression recognition. We hypothesized that produc- tion training using the automated […]
