Using a Key Informant Focus Group, Formative User Testing, and Theory to Guide Design of a Sleep Health BCSS

Designing effective applications is an important goal for software development researchers as well as practitioners. Researchers in the field of Persuasive Technologies have contributed significant theories intended to guide software developers. Yet due to the comprehensive nature of these theories as well as their recency, many aspects have not received much study—especially aspects that require integration of multiple theoretical perspectives. This paper applies a design science research approach to develop a sleep health app for use by college students. We use this setting to demonstrate how requirements gathered via a key informant focus group and formative user testing can be mapped to both persuasive system design and behavior change support system theories with the result of producing clear guidance for subsequent app design and assessment

Gamification Strategies : A Characterization Using Formal Argumentation Theory

Gamified software applications are omnipresent in everyday life. The idea of using game design elements in non-game contexts to engage and motivate tasks has rapidly gained traction in the human–computer interaction and the psychology fields, but scarcely in the artificial intelligence (AI) research area. In this paper, we propose a software agent perspective of gamification elements to solve two specific problems: (1) a reactive perspective that gamification designers have for those gamified affordances, i.e. the visual cue (output) is only triggered by user interaction, and (2) a lack of formal treatment of gamified software, where strict characterization of software behavior as done in AI, guarantee that the information-based output follows the intended goal of the software. Our contributions presented in this paper are (1) two taxonomies of affordances based on the type of information that every element communicates, and the type of agency that is capable; (2) a framework to formalize the decision-making process for gamified software agents; and (3) a characterization of gamified stories using formal argumentation theory dialogues. We exemplify our contributions with two gamified platforms in the healthcare and financial literacy fields.© The Author(s) 2022.

Emotions in context: examining pervasive affective sensing systems, applications, and analyses

Pervasive sensing has opened up new opportunities for measuring our feelings and understanding our behavior by monitoring our affective states while mobile. This review paper surveys pervasive affect sensing by examining and considering three major elements of affective pervasive systems, namely; “sensing”, “analysis”, and “application”. Sensing investigates the different sensing modalities that are used in existing real-time affective applications, Analysis explores different approaches to emotion recognition and visualization based on different types of collected data, and Application investigates different leading areas of affective applications. For each of the three aspects, the paper includes an extensive survey of the literature and finally outlines some of challenges and future research opportunities of affective sensing in the context of pervasive computing

Designing, Developing, Evaluating, and Implementing a Smartphone-Delivered, Rule-Based Conversational Agent (DISCOVER): Development of a Conceptual Framework

Background: Conversational agents (CAs), also known as chatbots, are computer programs that simulate human conversations by using predetermined rule-based responses or artificial intelligence algorithms. They are increasingly used in health care, particularly via smartphones. There is, at present, no conceptual framework guiding the development of smartphone-based, rule-based CAs in health care. To fill this gap, we propose structured and tailored guidance for their design, development, evaluation, and implementation. Objective: The aim of this study was to develop a conceptual framework for the design, evaluation, and implementation of smartphone-delivered, rule-based, goal-oriented, and text-based CAs for health care. Methods: We followed the approach by Jabareen, which was based on the grounded theory method, to develop this conceptual framework. We performed 2 literature reviews focusing on health care CAs and conceptual frameworks for the development of mobile health interventions. We identified, named, categorized, integrated, and synthesized the information retrieved from the literature reviews to develop the conceptual framework. We then applied this framework by developing a CA and testing it in a feasibility study. Results: The Designing, Developing, Evaluating, and Implementing a Smartphone-Delivered, Rule-Based Conversational Agent (DISCOVER) conceptual framework includes 8 iterative steps grouped into 3 stages, as follows: design, comprising defining the goal, creating an identity, assembling the team, and selecting the delivery interface; development, including developing the content and building the conversation flow; and the evaluation and implementation of the CA. They were complemented by 2 cross-cutting considerations-user-centered design and privacy and security-that were relevant at all stages. This conceptual framework was successfully applied in the development of a CA to support lifestyle changes and prevent type 2 diabetes. Conclusions: Drawing on published evidence, the DISCOVER conceptual framework provides a step-by-step guide for developing rule-based, smartphone-delivered CAs. Further evaluation of this framework in diverse health care areas and settings and for a variety of users is needed to demonstrate its validity. Future research should aim to explore the use of CAs to deliver health care interventions, including behavior change and potential privacy and safety concerns.

Changing environmental behaviors through smartphone-based augmented experiences

Dissertação para obtenção do Grau de Mestrado em Engenharia de InformáticaThe use of persuasive technologies can induce changes in attitudes or behaviours, even in individuals that other strategies of persuasion can not reach effectively. In addition, this type of technology can be applied in numerous areas such as health, education, finance, e-business, among others. Although persuasion can be seen as something negative, being used to serve the interests of the persuader rather than the interests of the persuaded, this work aims to achieve a common and shared goal: to change people's behaviour towards the environment. A significant part of the population is still not aware of the sustainability problems that our planet is facing, so it is important to inform people about the theme while persuading them to change their behaviour and acquire proenvironmental attitudes. In this dissertation, work was conducted to alert citizens to this issue in a fun and immersive way using mobile devices, more specifically smartphones, and augmented reality technology that was used to create an environmental scanner. This scanner provided the user with informative insight about the surrounding environment, while highlighting the environmental threats. In addition to augmented reality, pro-environmental actions were positively reinforced using a reward system and a virtual character that interacted and motivated the user. A form of rapid spread through social networks was also created, allowing the persuasive effect to quickly reach a large number of users. Finally was performed a study to assess the success of the work done in changing behaviour towards environmental issues, and to study the influence of augmented reality and positive reinforcement in the changing of behaviours and acquisition of pro-environmental attitudes

MASELTOV Deliverable D7.1.1: Incidental Learning Framework

This is the first steps towards creating an ‘Incidental learning framework’, and it is a work in progress. It is intended that the Incidental learning framework will facilitate the creation of technology rich learning opportunities for immigrants within cities. The framework will be a descriptive mechanism that permits analysis, a generative tool to support software system design, and it will facilitate the communication of learning design ideas both visually and textually. The framework focuses on incidental learning i.e. learning that is spontaneous and unplanned, in the knowledge domains of interest to the MASELTOV project including health care, culture, and language and information access. However, it provides links and triggers to structured and reflective learning to back up and deepen learning that happens incidentally. This document describes the initial version of the Incidental Learning Framework, presents a few examples of its use, and describes some conclusions and recommendations for work towards the next version of the framework including • Using the framework to develop it, • Extending the literature review, • Gathering evidence about immigrants day-to-day lives, • Running design workshop(s) using the framework

An aesthetics of touch: investigating the language of design relating to form

How well can designers communicate qualities of touch? This paper presents evidence that they have some capability to do so, much of which appears to have been learned, but at present make limited use of such language. Interviews with graduate designer-makers suggest that they are aware of and value the importance of touch and materiality in their work, but lack a vocabulary to fully relate to their detailed explanations of other aspects such as their intent or selection of materials. We believe that more attention should be paid to the verbal dialogue that happens in the design process, particularly as other researchers show that even making-based learning also has a strong verbal element to it. However, verbal language alone does not appear to be adequate for a comprehensive language of touch. Graduate designers-makers’ descriptive practices combined non-verbal manipulation within verbal accounts. We thus argue that haptic vocabularies do not simply describe material qualities, but rather are situated competences that physically demonstrate the presence of haptic qualities. Such competencies are more important than groups of verbal vocabularies in isolation. Design support for developing and extending haptic competences must take this wide range of considerations into account to comprehensively improve designers’ capabilities

Design and wellbeing: Bridging the empathy gap between neurotypical designers and autistic adults

This paper is focused on the wellbeing of people with autism spectrum disorders, who are often excluded from design research. Drawing upon on-going design research collaboration between The Helen Hamlyn Centre for Design and the autism charity The Kingwood Trust, this paper reflects upon a neurotypical (i.e. not on the autism spectrum) designer’s experience of working with adults with autism who have limited verbal speech and additional learning disabilities. The hypothesis under investigation is that, by interacting with and observing a person in conjunction with his or her physical environment, the designer can unravel clues and insights to develop empathy and better understanding of a person with autism’s everyday experiences, which can thereby inform empathic designs that enhance and sustain a state of wellbeing. The conclusion explores how the inclusion of autistic people within the design process creates a shared experience, which helps to develop trust and empathy between the designer and the person with autism, enabling the designer to understand and appreciate different ways of being in the world

Quantifying the Impact of Making and Breaking Interface Habits

The frequency with which people interact with technology means that users may develop interface habits, i.e. fast, automatic responses to stable interface cues. Design guidelines often assume that interface habits are beneficial. However, we lack quantitative evidence of how the development of habits actually affect user performance and an understanding of how changes in the interface design may affect habit development. Our work quantifies the effect of habit formation and disruption on user performance in interaction. Through a forced choice lab study task (n=19) and in the wild deployment (n=18) of a notification dialog experiment on smartphones, we show that people become more accurate and faster at option selection as they develop an interface habit. Crucially this performance gain is entirely eliminated once the habit is disrupted. We discuss reasons for this performance shift and analyse some disadvantages of interface habits, outlining general design patterns on how to both support and disrupt them
