The major clues for emotion recognition are the text pieces inputted by the learners. The semantic inference of the emotions is done by use of an ontology called OMCSNet. The system also incorporates an agent that provides feedback based on the inferred emotions. The SUS (System Usability Scale) evaluation results show that this system achieves positive usability so that the learners enjoy the interaction with the system.","PeriodicalId":319764,"journal":{"name":"2011 IEEE Workshop on Affective Computational Intelligence (WACI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117225355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study examined whether the knowledge of searchers' emotions can be used to predict their actions (and vise versa). We investigated associations between information retrieval behaviors (e.g., examination of search results) and patterns of emotional expressions around those behaviors, and found that individual search behaviors were associated with the certain types of emotional expressions. The findings can inform classification of emotions and search behaviors, and in turn lead to the development of affect-sensitive retrieval systems.","PeriodicalId":319764,"journal":{"name":"2011 IEEE Workshop on Affective Computational Intelligence (WACI)","volume":"132 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120865910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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. The facial EMG activities evoked upon viewing a standard set of pictures selected from the International Affective Picture System (IAPS) and additional self selected pictures revealed that positive pictures led to increased facial EMG activities over zygomaticus major (F (2, 471) = 4.23, p < 0.05), whereas negative pictures elicited greater facial EMG activities over corrugator supercilii (F (2, 476) = 3.06, p < 0.05). In addition, the correlation between facial EMG activities over these two sites and participants' ratings of stimuli pictures in dimension of valence measured by Self-Assessment Manikin (SAM) was significant (r = −0.63, p < 0.001, corrugator supercilii, r = 0.51, p < 0.05, zygomaticus major, respectively). Our results suggest that emotion inducing pictures elicit the intended emotions and that corrugator and zygomaticus EMG can effectively and reliably differentiate negative and positive emotions, respectively.","PeriodicalId":319764,"journal":{"name":"2011 IEEE Workshop on Affective Computational Intelligence (WACI)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122984966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, endowing virtual humans with the ability to empathize not only enhances their cooperative social skills, but also makes them more likeable, trustworthy, and caring. Supported by psychological models of empathy, we propose an approach to model empathy for EMMA — an Empathic MultiModal Agent — based on three processing steps: First, the Empathy Mechanism consists of an internal simulation of perceived emotional facial expressions and results in an internal emotional feedback that represents the empathic emotion. Second, the Empathy Modulation consists of modulating the empathic emotion through different predefined modulation factors. Third, the Expression of Empathy consists of triggering EMMA's multiple modalities like facial and verbal behaviors. In a conversational agent scenario involving the virtual humans MAX and EMMA, we illustrate our proposed model of empathy and we introduce a planned empirical evaluation of EMMA's empathic behavior.","PeriodicalId":319764,"journal":{"name":"2011 IEEE Workshop on Affective Computational Intelligence (WACI)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124565476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, this paper presents results of two online surveys designed to evaluate a female android's facial display of five basic emotions. We prepared both surveys in English, German, and Japanese language allowing us to analyze for inter-cultural differences. Accordingly, we not only found that our design of the emotional expressions “fearful” and “surprised” were often confused, but also that many Japanese participants seemed to confuse “angry” with “sad” in contrast to the German and English participants. Although similar facial displays portrayed by the model person of Geminoid F achieved higher recognition rates overall, portraying fearful has been similarly difficult for the model person. We conclude that improving the android's expressiveness especially around the eyes would be a useful next step in android design. In general, these results could be complemented by an evaluation of dynamic facial expressions of Geminoid F in future research.","PeriodicalId":319764,"journal":{"name":"2011 IEEE Workshop on Affective Computational Intelligence (WACI)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122672190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
