This article provides a comprehensive overview of artificial intelligence (AI) for serious games. Reporting about the work European flagship project on game technologies, it presents set advanced AI components that enable pedagogical affordances and can be easily reused across wide diversity engines platforms. Serious functionalities include player modelling (real-time facial emotion recognition, automated difficulty adaptation, stealth assessment), natural language processing (sentiment...
The utilization of game elements in a non-game context is currently used vast range different domains. However, research on elements’ effects cognitive tasks still sparse. Thus, this study we implemented three elements, namely, progress bar, level indicator, and thematic setting, working memory training task. We evaluated the impact user performance perceived state flow when compared to conventional version Participants interacting with showed higher scores task than participants from...
Providing social robots an internal model of emotions can help them guide their behaviour in a more humane manner by simulating the ability to feel empathy towards others. Furthermore, growing interest creating that are capable collaborating with other humans team settings provides opportunity explore another side human emotion, namely, group-based emotions. This paper contributes first on robotic partners. We defined for allowed us create two distinct characters express either individual or...
This Special Interest Group (SIG) explores the transformative impact of Generative Artificial Intelligence (GenAI) on Human-Computer Interaction (HCI) research processes. The theme here is to answer "question zero": when use and refrain from using AI tools during cycle? discussion guided by five phases commonly used in HCI: planning, prototyping, data collection, analysis synthesis, dissemination communication. We investigate how GenAI accelerates project cycles, enhances reproducibility,...
Humans have a tendency to consider media devices as social beings. Social agents and artificial opponents can be examined one instance of this effect. With today's technology it is already possible create that are perceived socially present. In paper, we start by identifying the factors influence perceptions presence in human-agent interactions. By taking these into account following previously defined guidelines for building present opponents, case study was created which robot plays Risk...
This paper explores the role of prosocial behaviour when people team up with robots in a collaborative game that presents social dilemma similar to public goods game. An experiment was conducted proposed which each participant joined robot and selfish robot. During 5 rounds game, player chooses between contributing goal (cooperate) or his individual (defect). The prosociality level only affects their strategies play as one always cooperates other defects. We user study at office large...
Effectiveness of Serious Games (SG) depends very much on their capacity to provide the right balance be- tween gaming and educational experience. This require- ment raises challenges regarding realization in- telligence personalization. We aim overcome problems research fragmentation identify some main issues by presenting a summary relevant contributions from Artificial Intelligence Personal- ization, together with discussion future direc- tions. In this paper, we summarize approaches user...
Play is a central aspect of childhood development, with games as vital tool to promote it. However, neurodivergent children, especially those in neurodiverse environments, are underserved by HCI research. Most existing work takes on top-down approach, disregarding interest for the majority design process. Co-design often proposed create truly accessible and inclusive gaming experiences. Nevertheless, co-designing children within groups brings about unique challenges, such different...
State of the art agent-modelling tools support creation powerful Socially Intelligent Agents (SIAs) capable engaging in social interactions with participants various roles and environments. However, their deployment demands a laborious authoring task as it is necessary to manually define behaviour rules create content for different interaction scenarios. While research has centered on user experience, we shift focus authors. To understand challenges faced by authors who these agents,...
The blooming growth of interest in Serious Games (SG) over the last decade spread its applicational areas into an extremely wide and fragmented domain. As a consequence, it is difficult to create complete panorama snapshot regarding application SGs. With this work we contribute de-fragmentation domain Personal Social Learning & Ethics(PSLE). We established shared vocabulary with creation detailed taxonomy based on which carried out two surveys analyze 1) current status, trends gaps 2)...
The theory, models and architectures of intelligent agents are based loosely on the theory intentions from Bratman resulting in so-called BDI agents. Although this functions well for single it has been long recognized that approach falls short multi-agent systems. It lacks appropriate social aspects to make natural interaction possible. original concept was a (simple) idea how people reason about actions. We propose we go back foundation acknowledge core beings. I.e. don't function as...
Although Science, Technology, Engineering, and Mathematics (STEM) are essential for the development of society, men hugely outnumber women in majority STEM fields higher education, a factor that hinders inclusion restricts possibility having different points-of-view. Previous studies indicate multiple causes low female motivation degrees careers, which inspired several initiatives to increase interest STEM. A proven way captivate an audience change its attitude is heroic narrative model,...
This work addresses the challenge of creating virtual agents that are able to portray culturally appropriate behavior when interacting with other or humans. Because culture influences how people perceive their social reality it is important have agent models explicitly consider elements, such as existing relational factors. We addressed this necessity by integrating into a novel model for simulating human behavior. With model, we operationalized particular dimension culture—individualism...
