Detecting Student Emotions in Computer-Enabled Classrooms
Abstract: Affect detection is a key component of intelligent educational interfaces that can respond to the affective states of students. We use computer vision, learning analytics, and machine learning to detect students’ affect in the real-world environment of a school computer lab that contained as many as thirty students at a time. Students moved around, […]
Shoppernomics: How to Shorten and Focus the Shoppers Routes to Purchase
Shoppernomics: How to Shorten and Focus the Shoppers’ Routes to Purchase is a book by Roddy Mullin and Colin Harper that aims to help sales and marketing professionals understand and influence the decision-making process of their customers. The book is based on research and case studies from US and UK, and provides a framework for […]
The Forensic Biometric Analysis of Emotions from Facial Expressions and Physiological Processes from the Heart and Skin
Abstract: Decision-making, perception, memory and social interactions are greatly driven by emotion. Emotions can be measured from facial expressions through the facial muscles. A group of four students were exposed to emotionally loaded stimuli (videos and images) in its full complexity to assess the valence of the emotional expression, the associated arousal, skin respiration and […]
Enhancing the Professional Vision of Teachers: A Physiological Study of Teaching Analytics Dashboards of Students’ Repertory Grid Exercises in Business Education
Abstract: This paper reports on a study of the design, development and evaluation of two teaching analytics dashboards that visualize students’ repertory grid exercise data. The technical objective of the dashboards is to support teachers to investigate and compare personal constructs and element ratings by students for given topics of study at the individual student, […]
Physiology-based recognition of Facial micro-expressions using EEG and identification of the relevant sensors by emotion
Abstract: In this paper, we present a novel work about predicting the facial expressions from physiological signals of the brain. The main contributions of this paper are twofold. a) Investigation of the predictability of facial micro-expressions from EEG. b) Identification of the relevant features to the prediction. To reach our objectives, an experiment was conducted […]
A survey of technologies on the rise for emotion-enhanced interaction
Abstract: Emotions are a major part of the human existence and social interactions. Some might say that emotions are one of the aspects that make us truly human. However, while we express emotions in various life settings, the world of computing seems to struggle with supporting and incorporating the emotional dimension. In the last decades, […]
Investigation of Facial Micro-expressions of Emotions in Psychopathy – A Case Study of an Individual in Detention
Abstract: This paper explores the relationship between emotional triggers and various types of (positive / negative) facially displayed emotions by a subject from custody, diagnosed with psychopathy. In this case study, FME were manually measured by using the Facial Action Coding System (FACS, Ekman, Friesen, Hager, 2002), which taxonomies human facial movements by their appearance. […]
Transdermal neuromodulation of noradrenergic activity suppresses psychophysiological and biochemical stress responses in humans
Abstract: We engineered a transdermal neuromodulation approach that targets peripheral (cranial and spinal) nerves and utilizes their afferent pathways as signaling conduits to influence brain function. We investigated the effects of this transdermal electrical neurosignaling (TEN) method on sympathetic physiology under different experimental conditions. The TEN method involved delivering high-frequency pulsed electrical currents to ophthalmic […]
Differential emotion attribution to neutral faces of own and other races
Abstract: Past research has demonstrated differential recognition of emotion on faces of different races. This paper reports the first study to explore differential emotion attribution to neutral faces of different races. Chinese and Caucasian adults viewed a series of Chinese and Caucasian neutral faces and judged their outward facial expression: neutral, positive, or negative. The […]
Anticipatory Gaze Shifts during Navigation in a Naturalistic Virtual Environment
Abstract: In the real world, coupled eye and head movements are used by humans and other animals to orient their gaze toward objects or scenes of interest. In virtual environments a mouse is often used as a proxy for head movements, orienting the camera towards a desired view direction. The mouse also controls body direction […]
