    This special issue is about a research area which is developing rapidly. Pentland gave it a name which has become widely used, ‘Social Signal Processing’ (SSP for short), and his phrase provides the title of a European project, SSPnet, which has a brief to consolidate the area. The challenge that Pentland highlighted was understanding the nonlinguistic signals that serve as the basis for “subconscious discussions between humans about relationships, resources, risks, and rewards”. He identified it as an area where computational research had made interesting progress, and could usefully make more

    Consideration of persuasive technology on users acceptance of e-commerce: exploring perceived persuasiveness

    Get PDF
    Persuasive technologies, used within in the domain of interactive technology, are used broadly in social contexts to encourage customers towards positive behavior change. In the context of e-commerce, persuasive technologies have already been extensively applied in the area of marketing to enhancing system credibility, however the issue of ‘persuasiveness’, and its role on positive user acceptance of technology, has not been investigated in the technology acceptance literature. This paper reviews theories and models of users’ acceptance and use in relation with persuasive technology, and identifies their limitation when considering the impact of persuasive technology on users’ acceptance of technology; thus justifying a need to add consideration of ‘perceived persuasiveness’. We conclude by identifying variables associated with perceived persuasiveness, and suggest key research directions for future research

    Potential and effects of personalizing gameful fitness applications using behavior change intentions and Hexad user types

    Personalizing gameful applications is essential to account for interpersonal differences in the perception of gameful design elements. Considering that an increasing number of people lead sedentary lifestyles, using personalized gameful applications to encourage physical activity is a particularly relevant domain. In this article, we investigate behavior change intentions and Hexad user types as factors to personalize gameful fitness applications. We first explored the potential of these two factors by analyzing differences in the perceived persuasiveness of gameful design elements using a storyboards-based online study (N=178). Our results show several significant effects regarding both factors and thus support the usefulness of them in explaining perceptual differences. Based on these findings, we implemented “Endless Universe,” a personalized gameful application encouraging physical activity on a treadmill. We used the system in a laboratory study (N=20) to study actual effects of personalization on the users’ performance, enjoyment and affective experiences. While we did not find effects on the immediate performance of users, positive effects on user experience-related measures were found. The results of this study support the relevance of behavior change intentions and Hexad user types for personalizing gameful fitness systems further

    Digital Human Representations for Health Behavior Change: A Structured Literature Review

    Get PDF
    Organizations have increasingly begun using digital human representations (DHRs), such as avatars and embodied agents, to deliver health behavior change interventions (BCIs) that target modifiable risk factors in the smoking, nutrition, alcohol overconsumption, and physical inactivity (SNAP) domain. We conducted a structured literature review of 60 papers from the computing, health, and psychology literatures to investigate how DHRs’ social design affects whether BCIs succeed. Specifically, we analyzed how differences in social cues that DHRs use affect user psychology and how this can support or hinder different intervention functions. Building on established frameworks from the human-computer interaction and BCI literatures, we structure extant knowledge that can guide efforts to design future DHR-delivered BCIs. We conclude that we need more field studies to better understand the temporal dynamics and the mid-term and long-term effects of DHR social design on user perception and intervention outcomes

The definitive version was published in CHI PLAY '15 Proceedings of the 2015 Annual Symposium on Computer-Human Interaction in Play, https://doi.org/10.1145/2793107.2810260Serious and persuasive games and gamified interactions have become popular in the last years, especially in the realm of behavior change support systems. They have been used as tools to support and influence human behavior in a variety of fields, such as health, sustainability, education, and security. It has been shown that personalized serious and persuasive games and gamified interactions can increase effectivity of supporting behavior change compared to "one-size-fits all"-systems. However, how serious games and gamified interactions can be personalized, which factors can be used to personalize (e.g. personality, gender, persuadability, player types, gamification user types, states, contextual/situational variables), what effect personalization has (e.g. on player/user experience) and whether there is any return on investment is still largely unexplored. This full-day workshop aims at bringing together the academic and industrial community as well as the gaming and gamification community to jointly explore these topics and define a future roadmap.Österreichische ForschungsförderungsgesellschaftPeer-reviewe

    Argumentation Schemes for Events Suggestion in an e-Health Platform

    Get PDF
    In this work, we propose the introduction of persuasion techniques that guide the users into interacting with the Ambient Assisted Living framework iGenda. It is a cognitive assistant that manages active daily living activities, monitors user's health condition, and creates a social network between users via mobile devices. The objective is to be inserted in a healthcare environment and to provide features like adaptive interfaces, user profiling and machine learning processes that enhance the usage experience. The inclusion of a persuasive architecture (based on argumentation schemes) enables the system to provide recommendations to the users that fit their profile and interests, thus increases the chance of a positive interaction.A.

    Exploring Green Information Systems and Technologies as Persuasive Systems: A Systematic Review of Applications in Published Research

    Get PDF
    Adopting eco-friendly behaviors has gained attention in multiple scientific fields ranging from psychology to business, to information systems and computer science. Combining knowledge of creating software solutions with behavioral science studies can enhance research on sustainability and contribute to fostering green attitudes. Considering current state of Green Information Systems and Technologies (IS/IT), we suggest employing persuasive techniques to create “green” solutions. Bridging studies of Persuasive Technologies and Behavior Change Support Systems with the Green IS/IT, we suggest that Persuasive Systems Design principles are capable of enhancing performance of “green” applications as well as improving eco-oriented behaviors in both individual and organizational user contexts. Having reviewed and analyzed published articles on environmentally-oriented systems, we examined which persuasive design principles are currently used and which ones could be utilized better in contemporary and future applications

    The Art of Persuasion: International/Comparative Human Rights, The Supreme Court of Canada and the Reconstitution of the Canadian Security Certificate Regime

    Get PDF
    In this dissertation, the author explores the jurisprudential foundations of the “relevant and persuasive” doctrine, which authorizes Canadian judges to rely on international and comparative human rights when interpreting the Charter of Rights and Freedoms. Viewed in its best light, this doctrine improves respect for human rights in two distinct ways: securing Canada’s compliance with its international human rights obligations and enhancing the responsiveness of state law to the global and multicultural context of Canadian society. However, actual jurisprudence suggests that the doctrine has helped undermine principles of respect for constitutional supremacy and respect for international law, in part because it does not contain clear, objective criteria governing what counts as a relevant and persuasive norm. In the absence of such criteria, “result-oriented” judges are free to instrumentally pick norms that help rationalize decisions made entirely on the basis of political and ideological factors. Some would go so far as to argue that the doctrine enables judges to use the rhetoric of human rights to constitutionally entrench relations of domination; there is some empirical evidence to support this claim. Given the increasingly global context of contemporary judicial decision-making, it is surprising that judges have not yet offered a convincing justification for the relevant and persuasive doctrine. This dissertation attempts to offer such a justification. Weaving together a wide range of legal and moral philosophy, argumentation theory and international law/international relations theory, the author hypothesizes that judicial decisions about the relevance and persuasiveness of international and comparative human rights follow the contours of rhetorical and dialogical processes distinctive to law. With a view to testing this hypothesis, he develops analytical frameworks that help observers rationally identify, construct and evaluate “persuasive” international and comparative human rights arguments. Using the court-led reconstitution of the Canadian security certificate regime as a case study, he then attempts to demonstrate how the relevant and persuasive doctrine operates, how it coheres with principles of respect for constitutional supremacy and international law, and how it can improve respect for human rights among a wide range of globally-situated discursive communities
