Virtual human technologies are now being widely explored as therapy tools for mental health disorders including depression and anxiety. 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.

Conversational agents are getting increasingly popular and find applications in health and customer services. 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.

Access to healthcare advice is crucial to promote healthy societies. Many factors shape how access might be constrained, such as economic status, education or, as the COVID-19 pandemic has shown, remote consultations with health practitioners. Our work focuses on providing pre/post-natal advice to maternal women. A salient factor of our work concerns the design and deployment of embodied conversation agents (ECAs) which can sense the (health) literacy of users and adapt to scaffold user engagement in this setting. We present an account of a Wizard of Oz user study of 'ALTCAI', an ECA with three modes of interaction (i.e., adaptive speech and text, adaptive ECA, and non-adaptive ECA). We compare reported engagement with these modes from 44 maternal women who have differing levels of literacy. The study shows that a combination of embodiment and adaptivity scaffolds reported engagement, but matters of health-literacy and language introduce nuanced considerations for the design of ECAs.

The development of applications with intelligent virtual agents (IVA) often comes with integration of multiple complex components. In this article we present the Agents United Platform: an open source platform that researchers and developers can use as a starting point to setup their own multi-IVA applications. The new platform provides developers with a set of integrated components in a sense-remember-think-act architecture. Integrated components are a sensor framework, memory component, Topic Selection Engine, interaction manager (Flipper), two dialogue execution engines, and two behaviour realisers (ASAP and GRETA) of which the agents can seamlessly interact with each other. This article discusses the platform and its individual components. It also highlights some of the novelties that arise from the integration of components and elaborates on directions for future work.

In the context of mental wellness support, trust and intimacy between a counselor and a patient are necessary to converge healing processes positively. However, convincing students to trust a virtual human for topics regarding mental wellness is a complex problem that requires understanding students' experiences. Based on research that discusses mental health as a concerning topic regarding Computer Science (CS) students, this paper investigates how undergraduate computing-related students perceive virtual humans' expertise on mental wellness support based on demographic resemblance on spoken accent and gender. Four virtual human counselors were developed to conduct the study, as 58 undergraduate computing-related students from two North American universities were recruited and assessed. Our findings suggest that students were less inclined to interact with a male virtual human than a female one. Also, that spoken accents can impact students' perceptions of expertise under students' multilingualism.

Immersive virtual worlds are increasingly being used for education, training, and entertainment, and virtual humans that can interact with human users in these worlds play many important roles. Understating the emotional constructs of the user and generating multimodal forms of communications that are aligned with the user's needs and input is key to designing AI agents. Most virtual agents and communicative systems lack the ability to understand enthusiasm or generate multimodal enthusiastic communicative presentations. In this work, we argue for the importance of including enthusiasm in the design of human-AI collaboration and communication and review the existing datasets and models that can be used to bridge the gap in this area.

The COVID-19 crisis has generated an increase of sleep problems in the general population. Digital technologies can help dealing with mental health repercussions of COVID-19 but their acceptance by the population need to be better understood. 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.

There is a new crisis emerging in human-agent interaction research: Instead of using validated questionnaires, individual studies are creating new questionnaires that claim to measure identical constructs. 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.

Creativity is a vital inherent human trait. 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.

Non-verbal communication body cues are paramount to interact. In this preliminary work, we explore ways to let Intelligent Virtual Agents (IVAs) simulating nonverbal communication capabilities. We propose an approach to control IVAs' reactive behaviour from the analysis of other agents' apparent motions, in a situation of "observed" IVAs that act and "observers" that react. For that, first a viewpoint-driven analysis of the observed agent's motion is done, and then a synthesis of this analysis induces the observers' reaction.
