Social network analysis is a popular topic in social science. However, it needs a lot of human labor to get the information in psychological analysis. In this paper, we propose a multi-camera based evaluation system which can automatically track and recognize the human activities in an environment, and then build the corresponding social network and personality graphs. The proposed system contains...
Emotion is an essential element of human behaviours. In this research, we investigated human behaviours related with the touch interface on a smartphone as a way to understand users' emotional states. As modern smartphones have various embedded sensors such as accelerometer and gyroscope, we aim to utilize data from these embedded sensors for recognizing human emotion and further finding emotional...
Psychologists found that human eye gaze direction has a very strong influence on facial expression. However, there exist few researches that took eye gaze direction into consideration while recognizing facial expressions. This paper makes use of the combination of eye gaze and facial expression information to detect human emotion. First, eye gaze direction is categorized into direct gaze and avert...
Recently, affective computing findings demonstrated that emotion processing and recognition is important in improving the quality of human computer interaction (HCI). In the present study, new data for a robust discrimination of three emotional states (negative, neutral and positive) employing two-channel facial electromyography (EMG) over zygomaticus major and corrugator supercilii will be presented...
Recent research in the field of Human Computer Interaction aims at recognizing the user's emotional state in order to provide a smooth interface between humans and computers. This would make life easier and can be used in vast applications involving areas such as education, medicine etc. Human emotions can be recognized by several approaches such as gesture, facial images, physiological signals and...
Humans have the ability to use a complex code of non-verbal behavior to communicate their internal states to others. Conversely, the understanding of intentions and emotions of others is a fundamental aspect of human social interaction. In the study presented here we investigate how people perceive the expression of emotional states based on the observation of different styles of locomotion. Our goal...
To test whether emotional feature has precedence in emotional prosody processing, the present study asks subjects to determine the change of the sentence via emotional feature or intensity while Event-related potentials (ERPs) were recorded. The result indicated that listeners are more accurate and faster at determining the changes of emotional feature than intensity, and the changes of emotional...
In this paper, we developed a procedure for producing head and face movements during speech by a virtual pedagogical agent by combining different voice recordings, different facial expressions and different head movement patterns. We then developed three experimental conditions to evaluate how the facial expressions and head movements contribute to learning experiences and outcomes. Results showed...
With gradual adoption of “multimedia” technologies on the curriculum designs in modern education, there are increasing needs for in-depth studies thoroughly exploring how different types of multimedia materials affecting learner's emotion and their learning performance. By the introduction of technological advancement on human physiological signals recognizing emotional variances, reliable emotion...
Human-Computer Interaction (HCI) research groups have recently attracted to the issue of emotion or affect especially in the examination of interaction and design. With recent technological advances, human users are able to interact with computers in ways which are almost impossible. New modalities for computer interaction with human emotion such as skin conductivity, heart rate, brain signals and...
Facial expressions and emotive voices are not processed independently, but interact implicitly. We investigated effects of facial expressions by 2-dimensional (2D) and 3-dimensional (3D) faces on perceived emotions of non-sense voices using psychophysical methods. We found that the perceived emotion of voices was facilitated with 3D faces, and was modulated in the direction of presented facial expressions...
In order to build the intelligent tutoring system, according to the basic theory of emotional psychology, the emotion mathematical model and the personality-moods-emotions multilayer model are used in this paper. By analyzing facial emotions, body emotions of the learner and the difficulty level of knowledge, we use the advantage of Credal networks to deal with uncertainty and ambiguity of data and...
With the approach of “eyeball” economy era, product animation is playing an increasingly role of cultural mediation in brand communication. Therefore, visual image becomes the guide of visual form, the communicator of brand information, the interpreter of aesthetic emotion in product animation gradually. This thesis starts with three aspects which are the nature of image, the cognitive basis of image...
Due to the essential features of music emotion, affective computing research in the field of music can accomplish much. And it is becoming a hot issue in the field of artificial intelligence and multimedia. This paper analyses the forms and contents of affective computing research, and focus on the content of the three specific researches: computer music emotion recognition, emotional semantic-driven...
Very little is know about how the patterns of collective experiences towards a Place can quantitatively as well as qualitatively be represented based on subjective data. Therefore, our research challenge is two-fold: (a) to define what Place is by pointing to ways in which emotion states can be observed and are bound together within a social network; and (b) to develop a visual representation that...
Affective computing has been investigated by many to allow computers to respond to or react to human or user emotion. In this paper, a model of personality and emotion was proposed based on the architecture of a cognitive system. Considering the external and internal factors of a virtual agent, formalized description of the emotional model was built. Experiment results indicated that the emotion generated...
This paper proposes an emotion recognition system based on the Mel Frequency Cepstral coefficient (MFCC) of the bio-signals. Using gathered data under psychological emotion stimulation experiments, 4 types of emotions, happy, fear, sad and calm are classified. MLP is used as the classifiers. Experimental results show potential of using this technique to verify emotion based on the EEG signals of accuracy...
To meet the real world challenges for speech emotion recognition, four emotions for practical use were studied for evaluation of work ability. Elicited speech corpus was collected in a psychology experiment to provide trustable emotion data, acoustic features related to arousal and valence dimensions were selected specially for the practical emotions and a re-compositive GMM method was used for the...
This paper presents a novel human-computer interaction in smart home healthcare, which is an interdisciplinary research project between computer science, social work and psychology, an integration of human, smart home environment and healthcare services is connected with the intelligent interface, which processes sensory modalities input via facial, vocal, eye-tracking, and physiological signals,...
Emotion and race are two major aspects of human mental life that are widely regarded as distinct. However, it is still under debate whether the race affects emotion processing or not. The studies based on Event-related potentials indicated many interesting results, but conflicting conclusions to some degree. This paper presents a study on how race influences emotion cognition during a cognitive task...
