HCI as a means to prosociality in the economy

HCI research often involves intervening in the economic lives of people, but researchers only rarely give explicit consideration to what actually constitutes prosociality in the economy. Much has been said previously regarding sustainability but this has largely focused on environmental rather than interpersonal relations. This paper provides an analysis of how prosocial HCI has been discussed and continues to be defined as a research field. Based on a corpus of published works, we describe a variety of genres of work relating to prosocial HCI. Key intellectual differences are explored, including the epistemological and ethical positions involved in designing for prosocial outcomes as well as how HCI researchers posit economic decision-making. Finally, emerging issues and opportunities for further debate and collaboration are discussed in turn

Designing and Using Carbon Management Systems to Promote Ecologically Responsible Behaviors

With the hope of mitigating the harmful impacts of climate change, many organizations are taking actions to reduce their carbon footprints. Carbon-reducing initiatives in organizations are varied: they range from green product innovations to encouraging behavioral changes by customers and employees. Green IS can play an important role in environmental sustainability by supporting a number of these strategies. Drawing on theories of persuasive systems design, this paper explores how one category of Green IS, carbon management systems (CMS), can be designed and used in order to persuade employees to perform ecologically responsible behaviors. The results from three organizational case studies suggest that CMS can be effective at changing employees’ environmental behaviors, demonstrate the extent to which persuasive system design principles (including an emergent category of Integration) are reflected in CMS, and highlight the importance of understanding the persuasion context. The findings of the study are used to inform the development of four propositions, which can serve as a foundation for further research in the Green IS domain

The ethical implications of HCI’s turn to the cultural

We explore the ethical implications of HCI’s turn to the ‘cultural’. This is motivated by an awareness of how cultural applications, in our case interactive performances, raise ethical issues that may challenge established research ethics processes. We review research ethics, HCI’s engagement with ethics and the ethics of theatrical performance. Following an approach grounded in Responsible Research Innovation, we present the findings from a workshop in which artists, curators, commissioners, and researchers explored ethical challenges revealed by four case studies. We identify six ethical challenges for HCI’s engagement with cultural applications: transgression, boundaries, consent, withdrawal, data, and integrity. We discuss two broader implications of these: managing tensions between multiple overlapping ethical frames; and the importance of managing ethical challenges during and after an experience as well as beforehand. Finally, we discuss how our findings extend previous discussions of Value Sensitive Design in HCI

Brand Community Interface Design: An Adapted Method for User Experience Research

As the field of user experience research grows, it is logical for its selection of methods to grow as well. This dissertation seeks to shed light on a research method traditionally used in other fields (namely, philosophy and more recently, marketing and consumer behavior) and how that method can be adapted and applied to user experience research. The goal is to investigate the method of existential phenomenology and the use of phenomenological interviews in order to determine if it is an appropriate research method for the constructivist approach to user experience. This dissertation begins by familiarizing the reader with three main areas of study that were employed to inform the research: usability and user experience, brand communities, and identity and the act of identification. Next, the method of existential phenomenology is addressed and the exact research process performed for the project is explained. Results from the interviews and their initial analysis via multiple coding strategies are described. Finally, analysis and application of the results are presented in an effort to demonstrate how designers can employ existential phenomenology and phenomenological interviews to inform interface design. Based on the findings of the project, this adapted method can be considered a constructivist approach to user experience research and it does provide actionable results that can be employed by designers to inform interpellative interfaces

Emerging policy problems related to ubiquitous computing

Peer-reviewed journal articleThis paper provides an overview of the human-centered vision of Ubiquitous Computing and draws on research examining slowly emerging problems over a long-term time frame in the emerging Ubiquitous Computing environment. A six-phase process employing scenario planning, electronic focus groups, and problem assessment surveys harnessed the insight of 165 individuals from diverse backgrounds and regions throughout the State of Hawaii. Distinct differences were found between the problem identification of specialists (policymakers and systems designers) and non-specialists (everyday citizens), and there were significant differences found in the problem assessment between groups. The greatest differences in both phases emerged from social and psychological issues related to the emerging Ubiquitous Computing environment. It is argued that in addition to enormous technical changes, Ubiquitous Computing will serve to blur sociotechnical boundaries throughout the environment, challenging existing distinctions between humans and machine intelligences. As the potential for extending human capabilities via computing and communications technology is actualized in coming decades, what it means to be human will be a major source of public policy conflicts, and the early identification of problems related to these changes is essential in order to mitigate their impacts and socially negotiate a more desirable future

Factors That Enhance Consumer Trust in Human-Computer Interaction: An Examination of Interface Factors and Moderating Influences

The Internet coupled with agent technology presents a unique setting to examine consumer trust. Since the Internet is a relatively new, technically complex environment where human-computer interaction (HCI) is the basic communication modality, there is greater perception of risk facing consumers and hence a greater need for trust. In this dissertation, the notion of consumer trust was revisited and conceptually redefined adopting an integrative perspective. A critical test of trust theory revealed its cognitive (i.e., competence, information credibility), affective (i.e., benevolence), and intentional (i.e., trusting intention) constructs. The theoretical relationships among these trust constructs were confirmed through confirmatory factor analysis and structural equation modeling. The primary purpose of this dissertation was to investigate antecedent and moderating factors affecting consumer trust in HCI. This dissertation focused on interface-based antecedents of trust in the agent-assisted shopping context aiming at discovering potential interface strategies as a means to enhance consumer trust in the computer agent. The effects of certain interface design factors including face human-likeliness, script social presence, information richness, and price increase associated with upgrade recommendation by the computer agent were examined for their usefulness in enhancing the affective and cognitive bases for consumer trust. In addition, the role of individual difference factors and situational factors in moderating the relationship between specific types of computer interfaces and consumer trust perceptions was examined. Two experiments were conducted employing a computer agent, Agent John, which was created using MacroMedia Authorware. The results of the two experiments showed that certain interface factors including face and script could affect the affective trust perception. Information richness did not enhance consumers’ cognitive trust perceptions; instead, the percentage of price increase associated with Agent John’s upgrade recommendation affected individuals’ cognitive trust perceptions. Interestingly, the moderating influence of consumer personality (especially feminine orientation) on trust perceptions was significant. The consequences of enhanced consumer trust included increased conversion behavior, satisfaction and retention, and to a lesser extent, self-disclosure behavior. Finally, theoretical and managerial implications as well as future research directions were discussed

21st century social work: reducing re-offending - key practice skills

This literature review was commissioned by the Scottish Executive’s Social Work Services Inspectorate in order to support the work of the 21st Century Social Work Review Group. Discussions in relation to the future arrangements for criminal justice social work raised issues about which disciplines might best encompass the requisite skills for reducing re-offending in the community. Rather than starting with what is known or understood about the skills of those professionals currently involved in such interventions, this study sought to start with the research evidence on effective work with offenders to reduce re-offending and then work its way back to the skills required to promote this outcome
