We have already proposed a chat system representing a facial expression corresponded to user’s emotion called JavaFaceChat. However it is difficult to use JavaFaceChat on mobile phone because it requires some complicated tasks, large databases, and natural language processing. Therefore, we construct a simple version of JavaFaceChat. The system calculates seven types of emotions (angry, disgust...

For the interaction among human and machine communication systems, extraction and understanding of Emotion is of high importance. The most expressive way to display the human’s emotion is through facial expression analysis. Facial expression is an important channel for human communication and can be applied in many real applications. This paper presents and implements the detection and recognit...

Research on the facial expression of emotion distinguishes between correlates of posed vs. spontaneous emotion expression. Similar research in the vocal domain is lacking. In this study, we compare changes in a range of vocal parameters between posed vs. spontaneous adult-directed (AD) and child–directed (CD) speech. CDS is a highly affectively charged speech register which lends itself well to...

In recent years, thermal image has extensively been used in many fields such as military (e.g., target acquisition, surveillance, night vision, homing and tracking) and civilian purposes (e.g., medical diagnosis, thermal efficiency analysis, environmental monitoring). It may be a promising alternative for investigation of facial expression and emotion. Currently there are very few database to s...

This study investigated the influence of emotion on toddlers’ prosocial behavior in instrumental helping tasks with an unfamiliar adult. The goals were to examine whether early prosocial behavior was affected by (1) the adult’s expressions of sadness (in contrast to a neutral expression) as a cue of need and (2) toddlers’ emotion understanding. Thirty-five 18to 20-month-olds participated in eig...

Emotion is a relatively new field of study, filled with assumptions and limited in previous research. In current studies, researchers know that emotions involve physiological and behavior responses somehow, but even the basic concept of ‘emotion’ is unclear. Further, few studies have looked at the intersection of auditory stimulus facial emotion recognition. This study conducts an experiment wh...
