THE EFFECTS OF ANTHROPOMORPHISM AND AFFECTIVE DESIGN PRINCIPLES ON THE ADOPTION OF M-HEALTH APPLICATIONS

Published ThesisPrevious research has found that M-Health initiatives have not been adopted and used effectively in many cases, especially in rural communal locations. Based on this, the researcher has surmised that factors contributing to the non-use of such initiative could be the resulted of a lack of knowledge with regard to the use of technology, literacy challenges, possible fear of technology and a lack of information regarding interventions that have the potential to improve quality of life. Consequently, an initiative that has usability as its core function may play a critical role in the use and adoption of such technologies. The researcher wondered if and how anthropomorphic and affective design principles which aspire to extract an emotional or positively reinforced sub-conscious reaction from users may influence the adoption and use of M-Health initiatives when applied to said interventions. This study therefore set out to investigate the effects of anthropomorphism and affective design principles on the adoption of M-Health applications, with the Sethakeng rural community in the Northern Cape province of South Africa research population after consent was obtained from the relevant community leaders. The researcher wanted first to ascertain whether anthropomorphism and affective design could influence the adoption of Mobile-Health applications, then to identify which was the more effective method to design Mobile-Health applications and finally, to provide guidelines and recommendations about the most effective design theory, as identified in the study, when designing applications. This study predominantly employed a mixed approach research methodology which included action research cycles and quantitative data in the form of usage statistics, obtained from CloudWare, in the final report. A case study was conducted in a rural South African setting to explore and eventually understand the relation between the case community and the intervention. A qualitative research design best allowed the researcher to get a better understanding of the research problem identified and the obstacles facing the relevant rural community and quantitative data assisted with better understanding the relevant usage trends in terms of the M-Health intervention. The objectives of the case study were to observe the phenomenon and describe it with regards to the case community, document the reactions of the case community to different instances and variations of the phenomenon and, lastly, to report on the design principle that yielded the most positive reaction from the community from a usage perspective; thereby indicating the adoption of the design methodology employed. The research contributed towards the successful development, placement and scrutiny of two emotion-driven interfaces for the same M-Health intervention. A distinctive perspective was provided with regard to affective and anthropomorphic design to identify the better design model for improved application acceptance in a rural community context. At the conclusion of the study, evidence suggested that community members found the anthropomorphic interface design superior. The researcher was thus able to explore, identify, develop and list a set of guidelines that can be used in the area of emotional design. Each guideline was based on what worked in practice and was applied successfully throughout this study. The researcher would like these guidelines be implemented and utilised by other designers in the field of interaction design for future designers

Coping with the inheritance of COVID-19: the role of new interactive technologies to enhance user experience in different contexts of use

The COVID-19 pandemic has upset the habits of people and various sectors of society, including training, entertainment, and retail. These sectors have been forced to adapt to abnormal situations such as social distancing, remote work, and online entertainment. The pandemic has significantly transformed the training field, leading to the closure of many in-person instruction centers and a shift toward online education courses, which can be less effective. In addition, the entertainment industry has been heavily transformed by social distancing, resulting in the cancellation of many live events and the closure of several cinemas. This has increased demand for online entertainment options, such as streaming services and virtual events. Finally, the restrictions imposed by the COVID-19 pandemic substantially impacted physical stores and fairs, suspending exhibitions for more than two years. This has further driven consumers to rely on e-commerce to fulfill their purchasing and companies to increasingly take advantage of new technologies such as augmented reality. In this suddenly disrupted scenario, new technologies have the potential to fill the gap generated by the pandemic, functioning as an interactive bridge to connect people. This Ph.D. thesis explored the potential of interactive technologies in mitigating the challenges posed by the COVID-19 pandemic in various contexts of use in the above-mentioned areas. Specifically, three lines of research were investigated by conducting different studies using a mixed approach in the Human-Computer Interaction field. The first research line focused on the study of immersive virtual reality training, with a particular interest in flood emergencies, a growing phenomenon. The goal was to implement engaging and efficient training for citizens that live near rivers through a human-centric design approach. The second line of research explored innovative ways to improve social interaction and collaboration in the entertainment sector, highlighting guidelines for the design of shared streaming experiences. In particular, three different communication modalities were studied during group viewing of an interactive film on a streaming platform. Finally, the third research line focused on the retail sector. On the one hand, the focus consisted of understanding which aspects of the 3D web and AR technology are helpful for supporting small businesses and trade fairs. On the other hand, the focus was to investigate how to support consumers during an AR shopping experience when interacting with 3D virtual products of different sizes. Overall, this project provides suggestions and guidelines for designing systems that can both increasingly connect people at a distance and offer new hybrid worlds. In addition, this project expands state-of-the-art related to interactive technologies and offers generalizable results outside the crisis created by COVID-19. These technologies, now increasingly integrated into everyday life, can be a tool for empowerment and resilience, improving people's lives.The COVID-19 pandemic has upset the habits of people and various sectors of society, including training, entertainment, and retail.

VIL: A Visual Inter Lingua

As the world becomes smaller through advances in telecommunications, the need for communication between speakers of different languages becomes greater. Concerns about cultural and economic hegemony argue against the use of any natural language, and machine translation is not yet perfected and available to speakers of all languages. With the technological developments of the last decade, such as powerful computers, graphical interfaces, and the World Wide Web, an excellent opportunity has been created for a computer-mediated visual interlingua to meet this need. An iconic language could be designed to take advantage of the technology. People would be able to communicate with an iconic language without the need to draw pictures themselves, since they could choose these pictures from the screen. This dissertation describes VIL, an iconic visual interlingua based on the notion of simplified speech. Similar to pidgins, languages arising from the prolonged contact between people speaking two or more languages, VIL utilizes features that are in the \u27greatest common denominator\u27 of features in different languages. This allows its complexity to be significantly reduced; for example, it has no inflection, no number, gender, or tense markers, and no articles. VIL has no linear order. This is possible because it was designed as a visual language, in contrast to written languages which are the result of a transfer to visual modality of spoken language, which evolved in the context of auditory modality where sequencing and ordering is critical. After reviewing previous research on universal languages that are artificial, non-artificial, and visual, VIL is described in detail, including its parts of speech, its grammar, and its organization for verbs, nouns, and adjectives. Throughout the discussion a set of principles is proposed, some of which are relevant to any universal language, others specific to visual or iconic languages. The development of a set of icons is also presented. Finally, the evaluations of the icons, language, and the system itself are described

Development and Usability Evaluation of an mHealth Application for Symptom Self-Management in Underserved Persons Living with HIV

Effective symptom management is essential to decrease symptom severity and improve health-related quality of life for persons living with HIV (PLWH). A mobile health (mHealth) application (app) has the potential to be an effective delivery mode of an existing paper-based symptom management manual with self-management strategies for underserved PLWH. The quality of the mHealth app requires a thorough understanding of the needs of the intended end-users and ensuring the app’s usability. The purpose of this study was to translate paper-based health information into an mHealth app for symptom self-management in underserved PLWH, entitled mVIP (mobile Video Information Provider), and assess its usability. To achieve this goal, usability was evaluated rigorously throughout the development process of mVIP. Based on a stratified view of health information technology (IT) usability evaluation framework, usability evaluation was sequentially conducted with the following three levels: 1) user-task, 2) user-task-system, and 3) user-task-system-environment. At level 1 (user-task), we applied a user-centered design method to guide the information architecture of mVIP. Using a reverse in-person card sorting technique, symptoms and self-management strategies from a paper-based HIV/AIDS symptom management manual were ranked. The rank order of the 13 symptoms and 151 self-management strategies determined the order of appearance to end-users of the mVIP app, with higher-ranked symptoms and strategies appearing first. Based on the findings, we developed a prototype of mVIP as following: 1) once users log in, they are guided by an avatar through a series of 13 symptom questions ascertaining the nature and severity of their symptoms, and 2) the avatar recommends three self-management strategies for each symptom reported. At level 2 (user-task-system), we conducted a usability evaluation of the mVIP prototype in a laboratory setting through end-user usability testing and heuristic evaluation. In end-user usability testing, we used an eye-tracking and retrospective think-aloud method to examine task performance by 20 PLWH. For the heuristic evaluation, five usability experts in informatics assessed the user interface. In the two usability evaluations conducted in a laboratory setting, we found strong user acceptance of the mVIP prototype while identifying a number of usability issues with this prototype. Based on the recommendations from the end-users and heuristic evaluators, we iteratively refined the app’s content, functionality, and interface. We then inserted videos of the finalized symptom self-management strategies into the refined mVIP prototype. At level 3 (user-task-system-environment), the usability of the refined mVIP prototype was evaluated in a real-world setting. Through 10 in-depth interviews and four focus groups conducted at the conclusion of a three-month randomized controlled trial, we explored in-depth understandings of users’ experiences, perceptions, and satisfaction of mVIP use. Findings from the study showed that first, mVIP is useful for HIV-related symptom self-management and has the potential for being used as a communication tool with healthcare providers; and second, mVIP is easy to use to monitor symptom experience over time. At the same time, participants suggested mVIP be more sensitively tailored based on years from initial diagnosis of HIV, an individuals’ age, and conditions. The overall user satisfaction with the mVIP prototype was high, which reflects strong user acceptance of mVIP. Integral to the findings from the three-level usability evaluation, we assessed the quality of the mVIP prototype in use and found the prototype was highly accepted by PLWH with high user satisfaction. This study will add to the body of literature on translation of evidence-based health information into an mHealth app and its usability assessment, which highlights the importance of the use of mobile technology for PLWH, specifically racial and ethnic minorities and those from low-socioeconomic groups who have limited health literacy and low level of education

Acceptance of Assistive Technology by Users with Motor Disabilities Due to Spinal Cord or Acquired Brain Injuries: A Systematic Review

: Acquired motor limits can be provoked by neurological lesions. Independently of the aetiologies, the lesions require patients to develop new coping strategies and adapt to the changed motor functionalities. In all of these occasions, what is defined as an assistive technology (AT) may represent a promising solution. The present work is a systematic review of the scientific AT-related literature published in the PubMed, Cinahl, and Psychinfo databases up to September 2022. This review was undertaken to summarise how the acceptance of AT is assessed in people with motor deficits due to neurological lesions. We review papers that (1) dealt with adults (≥18 years old) with motor deficits due to spinal cord or acquired brain injuries and (2) concerned user acceptance of hard AT. A total of 615 studies emerged, and 18 articles were reviewed according to the criteria. The constructs used to assess users' acceptance mainly entail people's satisfaction, ease of use, safety and comfort. Moreover, the acceptance constructs varied as a function of participants' injury severity. Despite the heterogeneity, acceptability was mainly ascertained through pilot and usability studies in laboratory settings. Furthermore, ad-hoc questionnaires and qualitative methods were preferred to unstandardized protocols of measurement. This review highlights the way in which people living with acquired motor limits greatly appreciate ATs. On the other hand, methodological heterogeneity indicates that evaluation protocols should be systematized and finely tuned

INTEGRATING IPTV AND SOCIAL NETWORKING WITH VOICE INPUT

Elderly people comprise the highest proportion of television viewers. Elderly people often struggle with new technology and reject it due to complexity. We propose a system to help people keep up with certain new technologies, such as IPTV and social networks with reduced efforts. We specifically propose a system to integrate IPTV with Twitter, a social networking website with an aid of a mobile phone. The system uses speech to text technology on mobile phone, as input to reduce the difficulty involved in the interaction with Twitter, while viewing television. As speech is a more convenient and natural way of expression than text, we anticipate that people from other age groups can also benefit from the system

It Goes Beyond Product - Business Innovativeness and Consumer's New Values Adoption

The concept of consumer behavior in today’s trend of competitiveness has been enriched by the study on consumer’s adaptation to new values. More specifically in this new era of digital technology business has been able to creatively promote values in which consumer’s loyalty is systematically developed. Business sells beyond product. Hierarchical regression and One-way Anova were employed to show the dynamic process of new values adoption. The respondents were Generation Z in Palembang – Indonesia. Within this scheme the process of new values adoption is conditioned by the innovative capacity of the business ie. innovativeness that attracts the market to learn newness. Consequently, consumer has become more advanced in his involvement to adapt with the innovativeness of the business. This conceptual research intends to rationalize the dynamic of consumer’s new values adoption within the frame of business innovativeness

Learnability makes things click : a grounded theory approach to the software product evaluation

The aim of this doctoral dissertation is to investigate the phenomenon of learnability more deeply in order to better understand the learnability process. Grounded theory was used to determine the ground concepts based on fifteen users’ (N=15) actions (N=1836) in the WebCT Campus Edition’s virtual environment. Based on this study, the phenomenon of learnability and the learnability process is understood in greater detail and defined from the human centric of view, where the human being is the key actor. This doctoral dissertation answers the following research problem: 1. How learnable is the WebCT Campus Edition’s virtual environment? 2. How can the phenomenon of learnability be defined in a new way? The WebCT Campus Edition virtual environment’s learnability was measured with performance time and directions of action. In addition, the traditional learnability metrics of performance time and direction of users’ actions was used to verify the theoretical model of learnability and its nonlinearity. The result of this study showed that the variety of the WebCT Campus Edition’s learnability was higher between the individual users than it was between the different tasks. Therefore, the variety of task difficulty, i.e. the complexity or easiness of the different part of the user interface, have less influence on learnability in the WebCT Campus Edition than do the individual users’characteristics. Thus, the research results confirm the results found in earlier studies, where two important issues for usability evaluation and therefore evaluation on learnability, are the tasks and users individual characteristics. The theoretical model of learnability with following phases of information search, data collection, knowledge management, knowledge form, knowledge build and the result of action were determined from data. The theoretical model of learnability and its main patterns of a) data collection-information search, b)knowledge build-knowledge form and c) information searchknowledge management proves that learnability is a non-linear process. Therefore, the phenomenon of learnability cannot purely be defined by the separate properties of learnability, i.e. the properties of a user interface and a progressively enhanced linear process illustrated with learning curves. The theoretical model of learnability is one of the rare models of learnability that is based on empirical data. The use of grounded theory methodology means that the phenomenon of learnability is studied through tacit knowledge, i.e. through users’ real actions and though explicit knowledge, the users cognitive processes during interaction i.e. the phenomenon of learnability is approached from the holistic point of view, where the phenomenon of learnability is seen as one holistic process. Thus triangulation, where the phenomenon is interpreted through several split case studies are therefore unnecessary in this research setting. In conclusion, too many studies are still conducted in a laboratory situation using traditional methodological paradigms. More learnability studies with new methodological approaches in the natural environments are needed were the human, learning and non-linear process of learnability are in focus. It is important to understand more deeply the process of learnability and investigate more in greater detail the key elements that enhance learnability and on the other hand, cause learnability problems for users. Finally, based on the theoretical models of learnability, we can develop tools for the commercial user interface world in order to measure and test the learnability process more precisely and better understand how skills are actually learnt and how “to click” learnability

Kodinportti Mobile user interface usability research and redesign

Abstract. Usability is described as follows “The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use”. Usability plays a crucial role in the success of interactive products and services. With good usability can be achieved an important competitive advantage in an ever-growing market if it is involved in software products development life cycle. User experience (UX) is based on people’s expectations and the following emotions and it involves extensively everything that happens outside the screen. UX design aims to emphasize features that are bringing pleasure in addition to practicality. Usability evaluation is easy and very cost-effective way to analyze user interface and find possible usability problems. In general, the empirical methods like heuristic evaluation and usability testing are the most used and principal means to evaluate user interfaces. This thesis focuses on exploring the usability of Kodinportti Mobile application. The motivation for the study is to improve its user interface (UI) more user-friendly using usability research methods that include heuristic evaluation, usability testing, and user experience research. The practical work in the study is responsible by the University of Oulu usability testing course student group and the group also reports the results of research. The goal of the study is to redesign the app’s UI. Kodinportti Mobile is designed to meet the needs of the residents of the housing association and serves as a supplement to the electronic bulletin board for the residents. Mobile application UI design applies the same basic guidelines as any other UI design process and in mobile application UI design, it is often recommended to keep it simple as possible and cut out as much as possible. The results of usability research revealed several flaws in the apps usability and user experience. In the final phase of the thesis, the concept plan of new UI was designed based on the research results. There was also a perception during the process that it would be recommendable that designers are involved in all stages of the process. That would improve the process and minimize the possibility of misunderstandings during the process, which will certainly have a positive impact on the result

Assistive Technology in Occupational Therapy

In this chapter, occupational therapists from leading specialists exploring ways they can collaborate with assistive technology (AT) users to help them get the most out of these devices. By gratefully acknowledging the advances in technology of the last century, people with disabilities can live independent lives, contribute to their communities, attend regular schools, and work in a career. This technological development means medically switching to a social model of technology presentation, where users are as much focused on social reintegration as their physical abilities. This change means that field workers will not be able to focus on delivering technology on their own but will have to go one step further and partner with consumers and communities to ensure that the aids are used in the best possible way
