We analyze the differences in the timing structure for the listener and next speaker in turn-changing and turn-keeping. The results of analysis show that the listeners in turn-keeping tend to look at the speaker more often first before the speaker looks at the listeners than the next speaker in turn-changing looks at the speaker first before the speaker looks at the next speaker when the eye contact with the speaker happens. The listeners in turn-keeping tend to look away from the speaker more often later after the speaker looks away from the listener than listeners and the next speaker in turn-changing looks away from the speaker later when the eye contact with the speaker happens. In addition, the interval between the end of eye contact, the end of the speaker's utterance, and the start of next speaker's utterance is different between the listener in turn-keeping, the listener in turn-changing, and the next speaker in turn-changing.","PeriodicalId":230150,"journal":{"name":"GazeIn '14","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132225046","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}

Usually, the selection operation is performed using a manual input device like a mouse or a joystick. Due to the visually rich and dynamic input, the required high attention, the long working time, and the challenging manual selection of moving objects, it occurs that relevant events are missed. To alleviate this problem we propose adding another event selection process, using eye-brain input. Our approach is based on eye tracking and EEG, providing spatio-temporal event selection without any manual intervention. We report ongoing research, building on prior work where we showed the general feasibility of the approach. In this contribution, we extend our work testing the feasibility of the approach using more advanced and less artificial experimental paradigms simulating frequently occurring, basic types of real surveillance tasks. The paradigms are much closer to a real surveillance task in terms of the used visual stimuli, the more subtle cues for event indication, and the required viewing behavior. As a methodology we perform an experiment (N=10) with non-experts. The results confirm the feasibility of the approach for event selection in the advanced tasks. We achieve spatio-temporal event selection accuracy scores of up to 77% and 60% for different stages of event indication.","PeriodicalId":230150,"journal":{"name":"GazeIn '14","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126097113","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}

The method provides additional channels to EEG-based methods (e.g., [8]) for the study of user attention and emotions. In order to validate the proposed approach, two tour guide applications were created with an embodied conversational agent (ECA) that presents cultural content about a real-tourist attraction. The agent simulates two attention-grabbing mechanisms - humorous and serious to attract the users' attention. A formal study was conducted to compare two tour guide applications in the lab. The data collected from the facial expression analysis and eye-tracking helped to explain particularly good and bad performances in retention tests. In terms of the study results, strong quantitative and qualitative evidence was found that an ECA should not attract more attention to itself than necessary, to avoid becoming a distraction from the flow of the content. It was also found that the ECA had an inverse effect on the retention performance of participants with different gender and their use on computer interfaces is not a good idea for elderly users.","PeriodicalId":230150,"journal":{"name":"GazeIn '14","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131654480","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}
