These technologies leverage the ability of the virtual agents to engage in naturalistic social interactions with a user to elicit behavioural expressions which are indicative of depression and anxiety. Research efforts have focused on optimising the human-like expressive capabilities of the virtual human, but less attention has been given to investigating the effect of virtual human mediation on the expressivity of the user. In addition, it is still not clear what an optimal task is or what task characteristics are likely to sustain long term user engagement. To this end, this paper describes the design and evaluation of virtual human-mediated tasks in a user study of 56 participants. Half the participants complete tasks guided by a virtual human, while the other half are guided by text on screen. Self-reported PHQ9 scores, biosignals and participants' ratings of tasks are collected. Findings show that virtual-human mediation influences behavioural expressiveness and this observation differs for different depression severity levels. It further shows that virtual human mediation improves users' disposition towards tasks.","PeriodicalId":148152,"journal":{"name":"Proceedings of the 21st ACM International Conference on Intelligent Virtual Agents","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124984869","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}

Conversations in these fields are often emotionally charged. It is, therefore, necessary to handle the conversation with some degree of empathy to be effective. In this work, we leverage advances in the field of natural language processing to create a dialogue system that can convincingly generate empathic responses to text-based messages. To improve the system's ability to converse with empathy, we train the language model on empathic conversations and inject additional emotional information in the response generation. We propose two chatbots: a benchmark bot and an empathic bot. Additionally, we implement an emotion classifier that allows us to predict the emotional state of text-based messages. We evaluate both chatbots in quantitative studies and compare them with human responses in qualitative studies involving human judges. Our evaluation shows that our empathic chatbot outperforms the benchmark bot and even the human-generated responses in terms of perceived empathy. Additionally, we achieve state-of-the-art results in terms of response quality using transformer-based language models. Finally we report that we can double the initial performance of the emotion classifier using undersampling techniques, yielding a final F1-score of 0.81 in six basic emotions.","PeriodicalId":148152,"journal":{"name":"Proceedings of the 21st ACM International Conference on Intelligent Virtual Agents","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128640673","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}

KANOPEE is a smartphone application providing interactions with a virtual companion to screen and deliver personalized advices to deal with sleep problems. In this study we tried to highlight the factors associated with acceptance of this app, among factors including user characteristics, perceived trustworthiness of the virtual companion and context of use. 3,479 users answered the acceptance questionnaires, with a very positive attitude towards the app. Results indicate that age, education, familiarity with technologies, trustworthiness of the virtual agent and length of interaction are significantly associated with acceptance of the app. To conclude, this study is one of the first to measure acceptance of a virtual companion providing support during the COVID-19 crisis, and provide avenues of research for design and evaluation of intelligent virtual agents for health.","PeriodicalId":148152,"journal":{"name":"Proceedings of the 21st ACM International Conference on Intelligent Virtual Agents","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133533920","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}

This makes replication studies and comparisons between studies near to impossible. In turn, meta-analyses to determine which characteristics are important to create agents that the user experiences as being intelligent are difficult to conduct. As part of the attempt to battle this crisis, in this current paper, we suggest the use of a Theory of Mind task to measure the implicit social behaviour users exhibit towards a virtual agent. In a two-part study, we present findings that suggest that participants conduct this Theory of Mind task as expected: participants adapt towards our virtual agent more than when they conduct the task alone. We additionally present preliminary results correlating performance in the Theory of Mind task to validated constructs. Unfortunately, our current results do not correlate significantly to the existing constructs. Data-collection is ongoing and hence no firm conclusions can be made about this second set of results. However, our data suggest that it is important to become aware that the existing validated constructs used in HCI research may not be tapping into what the researchers assume, and hence provide a basis for important discussions about these implications.","PeriodicalId":148152,"journal":{"name":"Proceedings of the 21st ACM International Conference on Intelligent Virtual Agents","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125316644","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 an attempt to stimulate children's creativity, we present the design and evaluation of an interaction between a child and a social robot in a storytelling context. Using a software interface, children were asked to collaboratively create a story with the robot. We conducted a study with 38 children in two conditions. In one condition, the children interacted with a robot exhibiting creative behavior while in the other condition, they interacted with a robot exhibiting non creative behavior. The robot's creativity was defined as verbal and performance creativity. The robot's creative and non creative behaviors were extracted from a previously collected data set and were validated in an online survey with 100 participants. Contrary to our initial hypothesis, children's creativity measures were not higher in the creative condition than in the non creative condition. Our results suggest that merely the robot's creative behavior is insufficient to stimulate creativity in children in a child robot interaction. We further discuss other design factors that may facilitate sparking creativity in children in similar settings in the future.","PeriodicalId":148152,"journal":{"name":"Proceedings of the 21st ACM International Conference on Intelligent Virtual Agents","volume":"349 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132763273","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}
