Many of these technologies rely on a \"one-size fits all\" strategy -- self-monitoring -- to foster behavior change. However, individual's capacity to change their behaviors depends on their ability and motivation for self-regulation. We explore a different approach to persuasive technology design and investigate how subtle influences falling outside conscious awareness can instinctively motivate behaviors. Subliminal priming has the potential to influence people's attitudes and behaviors, without relying on people's will to engage with the process. Yet, little research has studied it effectiveness encouraging behavior change outside a laboratory setting. In this paper we explore the feasibility of subliminal priming on web-platforms. We present an in the wild study where 12 participants were exposed to subliminal cues to motivate water intake while they browsed on the web. This paper contributes with a practical application of subliminal priming in the field of behavior change as well as design implications for future research.","PeriodicalId":263115,"journal":{"name":"Proceedings of the 36th European Conference on Cognitive Ergonomics","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132573522","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}

Results show that the RPS stimulates debate about sociotechnical solutions, rules and rational criteria, in addition to sustainability values and ideological criteria. The RPS is thus a means for making sociotechnical solutions evolve and for identifying what is \"technically\", \"socially\" and \"ideologically\" necessary for acceptance and success of the future system.","PeriodicalId":263115,"journal":{"name":"Proceedings of the 36th European Conference on Cognitive Ergonomics","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121049140","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 end-user's state might be inferred by interactive timings, bodily movements or facial expressions. Problematic computerized stimuli are known to cause smiling during periods of frustration. Methods: Forty-four seated, healthy participants (age range 18-35, 18 male) used a handheld trackball to answer a computer-presented, formative, 3-way multiple choice geography quiz, with 9 questions, lasting a total of 175 seconds. Frontal facial videos (10 Hz) were collected with a webcam and processed for facial expressions by CrowdEmotion using a pattern recognition algorithm. Interactivity was recorded by a keystroke logger (Inputlog 5.2). Subjective responses were collected immediately after each quiz using a panel of visual analogue scales (VAS). Results: Smiling was five-fold enriched during the instantaneous feedback segments of the quiz, and this was correlated with VAS ratings for engagement but not with happiness or frustration. Nevertheless, smiling rate was significantly higher after wrong answers compared to correct ones, and frustration was correlated with the number of questions answered incorrectly. Conclusion: The apparent disconnect between the increased smiling during incorrect answers but the lack of correlation between VAS frustration and smiles suggests a trigger-substrate model where engagement is the permissive substrate, while the noises made by the quiz after wrong answers may be the trigger.","PeriodicalId":263115,"journal":{"name":"Proceedings of the 36th European Conference on Cognitive Ergonomics","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134181093","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}

Capitalizing on this ability, we developed a system that could help visually impaired people navigate by presenting them with sounds of lower or higher pitch according to their distance from objects that they gaze at. Eight blind-folded participants completed a Hebb-Williams Maze with the system and twelve blind-folded participants completed the maze without it. Both groups completed the maze five times. We found that participants completed the maze faster in the last three trials compared to the first trial. There were no differences between the groups in the pace of improvement and in the time to complete the maze. However, participants who used the system made less errors in the maze than participants who did not use it. Our findings indicate that the system can potentially assist visually impaired people navigate. The contribution of the system to navigation will be further investigated with larger number of participants and with more extensive training.","PeriodicalId":263115,"journal":{"name":"Proceedings of the 36th European Conference on Cognitive Ergonomics","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116675188","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}

Simulators have been used for training for decades and have evolved in different directions. To learn how applications evolve over time, it is important to understand what stimulates changes. There can be factors in the world external to the application, e.g. human, organizational and technological factors that stimulate changes and there can be factors internal to a software system, such as its structure and complexities.

The main contribution within this study is how a one-hour television drama can be measured in an applied research setting.
