Connecting Couples in Long-Distance Relationships : Towards Unconventional Computer-Mediated Emotional Communication Systems

The number of couples who find themselves in a long-distance relationship (LDR) is increasing for a wide range of reasons, such as overseas employment, academic pursuits, military duty, and similar circumstances. With the myriad of communication channels enabled by the low cost and ubiquity of computer-mediated communication technologies, couples in LDRs are able to stay in touch with each other around the globe. However, recent studies have revealed that the mainstream communication tools are inadequate to support the full spectrum of communication needed in intimate relationships. Emotional communication is one of the fundamental needs in close relationships, as it forms an important part of intimacy. This dissertation argues that there is a gap between what is known about LDR couples’ needs in research and what has been implemented for them in practice. The aim of this work is to bridge this gap by mediating emotional communication through unconventional user interfaces that use interaction solutions outside of the scope of their conventional use, with a particular focus on couples who sustain a committed LDR. Here, taking research through design as a core approach, a variety of qualitative methods were employed to seek answers to the research questions. This dissertation includes eight case studies, each of which is dedicated to answering its corresponding research question(s). Study I presents a systematic literature review which explored the current state of the art and identified the design opportunities. Study II introduces a series of co-design activities with five couples in LDRs to reveal the needs and challenges of users in an LDR. Studies III and IV propose two functional prototypes for unconventional communication systems to connect couples in LDRs. Study V showcases 12 design concepts of wearables created by the participants to support their own LDR. Study VI describes how four low-resolution prototypes created for mediating LDRs by the participants in the workshop would be used in real-world contexts. Studies VII and VIII each present a novel design tool to be used as a scaffold when designing communication systems for supporting LDRs: specifically, a conceptual design framework and a card-based design toolkit. This dissertation contributes new knowledge to the field of human-computer interaction through design interventions. It showcases a spectrum of practices which can be seen as a first step towards mediating emotional communication for couples in LDRs using unconventional communication systems. The findings comprise theoretical and empirical insights—derived from the eight case studies in which the author identified design opportunities and design considerations—relating to how couples in LDRs can be better supported by unconventional computer-mediated emotional communication systems

Investigations of collaborative design environments: A framework for real-time collaborative 3D CAD

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This research investigates computer-based collaborative design environments, in particular issues of real-time collaborative 3D CAD. The thesis first presents a broad perspective of collaborative design environments with a preliminary case study of team design activities in a conventional and a computer mediated setting. This study identifies the impact and the feasibility of computer support for collaborative design and suggests four kinds of essential technologies for a successful collaborative design environment: information-sharing systems, synchronous and asynchronous co- working tools, project management systems, and communication systems. A new conceptual framework for a real-time collaborative 3D design tool, Shared Stage, is proposed based upon the preliminary study. The Shared Stage is defined as a shared 3D design workspace aiming to smoothly incorporate shared 3D workspaces into existing individual 3D workspaces. The addition of a Shared Stage allows collaborating designers to interact in real-time and to have a dynamic and interactive exchange of intermediate 3D design data. The acceptability of collaborative features is maximised by maintaining consistency of the user interface between 3D CAD systems. The framework is subsequently implemented as a software prototype using a new software development environment, customised by integrating related real-time and 3D graphic software development tools. Two main components of the Shared Stage module in the prototype, the Synchronised Stage View (SSV) and the Data Structure Diagram (DSD), provide essential collaborative features for real-time collaborative 3D CAD. These features include synchronised shared 3D representation, dynamic data exchange and awareness support in 3D workspaces. The software prototype is subsequently evaluated to examine the usefulness and usability. A range of quantitative and qualitative methods is used to evaluate the impact of the Shared Stage. The results, including the analysis of collaborative interactions and user perception, illustrate that the Shared Stage is a feasible and valuable addition for real-time collaborative 3D CAD. This research identifies the issues to be addressed for collaborative design environments and also provides a new framework and development strategy of a novel real-time collaborative 3D CAD system. The framework is successfully demonstrated through prototype implementation and an analytical usability evaluation.Financial support from the Department and from the UK government through the Overseas Research Studentship Awards

Language Learning Effectiveness (Outcome) of an Online Synchronous EFL Program Compared to an ESL Face-to-Face Program

Abstract To provide English learning opportunities to International students while in their home countries, I designed an English as a Foreign Language (EFL) synchronous online program delivered via videoconferences. The purpose of this study was to evaluate the efficacy of an Online EFL program when compared to a regular in-person Intensive English Program (IEP) where students are immersed in the American culture. The control group was composed of 88 students from Spanish and Portuguese-speaking countries in South America that took the IEP offered by a private university in Kentucky in the past five years. Students in the control group had eight weeks of in-person English classes. The experimental group was composed of 88 students who participated in the EFL pilot course offered to Spanish and Portuguese-speaking students. The course was offered free of charge via zoom conferences twice a week for 8 eight weeks. The students were recruited over Facebook and WhatsApp. The study\u27s premise was to have students engaged in meaningful English language interactions with their peers and instructors to verify if there were significant differences between the pre and post-tests gains in both groups (Control and Experimental Group) of treatment (in-person and online English instruction). The results indicated a language gain in listening, grammar, and vocabulary for both groups, suggesting that both treatments produced similar language skills improvements. In virtue of the results, the author recognizes that the implementation of EFL programs delivered 100% online via videoconferences is a viable solution to problems of cost and mobility for English Language Learners (ELL), particularly in times of global crisis, such as the COVID-19 pandemic.

The Coconut Tree and the Computer Tiger: Information Technology in Traditional Pacific Societies

This literature review explores the extent to which Information Technology (IT) has affected the cultures of small traditional Pacific societies, with the South Pacific region as the point of focus. The assumption is that the educational systems of Pacific nations are in the developmental stage with the associated sophisticated technological applications. The thesis asks what if any, cultural challenges of adopting information technology have arisen? The review finds that traditional culture and information technology are in competition in the power stakes of human consideration, reflected in South Pacific indigenous academics seeking independence as researchers and acceptance in their own right. The realisation that culture and technology need to function together requires attaining academic freedom in the aftermath of post-colonial restrictions placed on the indigenous sociological and anthropological imagination. The first part examines the history of information technology generally, and the significance of work already done, providing a perspective of how the subject has developed and become established, assisting in the development and acquisition of the appropriate vocabulary. The review explains and describes the occurrence of information technology in the South Pacific, the effect of globalisation and shared knowledge through ethno-methodology, every day culture in action, describing the ways in which people make the sense they do and through the ways they communicate. In the second part the focus is on the detail of the commonsense character of everyday life and the practices by which they make their actions understandable by others. Scrutiny of how people do what they do provides an explanation of what those people do and why they do it in the way they do. Western form of governance is a reality, with nation building based on Western models of development. National independence and sovereignty with a wave of neo-colonialism and aid dependency led to economic globalisation, with resentment against value systems that erode indigenous values, producing a wave of re-indigenisation facilitated by the revolution known as information technology . There is a coherent body of Pacific thought, with a shared philosophy and ethic on the public agenda. In the material covered, elements standing out are the awareness among growing numbers of Pacific academics of the need for a genuine and far-reaching contextualisation, acknowledging the relevance and applicability of indigenous cultural values in contemporary settings. Second is the success of communities whose initiatives have followed familiar traditional ways they know and understand, reaping rewards. The region has development and governance failures in Papua New Guinea, Solomon Islands and Fiji to name a few; the national state of affairs in some countries is not encouraging. Where good development and governance are occurring, it is usually through the direct initiative of local communities using their knowledge base. The information upheaval is creating new opportunities in the lives of people from small traditional societies. Information Technology expands throughout the social structure of the Pacific in direct proportion to personal computer access literally at one's finger tips

ECSCW 2011 Conference Supplement: European Conference on Computer-Supported Cooperative Work Aarhus, 24.-28. September 2011

Dual eye-tracking (DUET) is a promising methodology to study and support collaborative work. The method consists of simultaneously recording the gaze of two collaborators working on a common task. The main themes addressed in the workshop are eye-tracking methodology (how to translate gaze measures into descriptions of joint action, how to measure and model gaze alignment between collaborators, how to address task specificity inherent to eye-tracking data) and more generally future applications of dual eye-tracking in CSCW. The DUET workshop will bring together scholars who currently develop the approach as well as a larger audience interested in applications of eye-tracking in collaborative situations. The workshop format will combine paper presentations and discussions. The papers are available online as PDF documents at http://www.dualeyetracking.org/DUET2011/

Activity Theory as Theoretical Framework for Analyzing and Designing Global K-12 Collaborations in Engineering: A Case Study of a Thai-U.S. Elementary Engineering Project

The American engineering pipeline requires future workers to possess a unique skill set, comprised of content knowledge and 21st century skills, to recruit highly skilled, globally competitive engineers. Generally, 21st century skills are defined as the ability to think critically, communicate, collaborate in teams, and creatively solve problems. These skills are pertinent in training future engineers provided engineering utilizes the application of scientific knowledge within an inherently collaborative modality (the engineering design process). One component of developing 21st century skills and engineering competencies is the need for students to broaden their global awareness. Hence, American K-12 teachers are actively seeking opportunities for their students to collaborate with their international peers in an engineering context. One emergent pedagogical strategy is engaging in global K-12 collaborations in engineering in which K-12 students collaborate with international counterparts (another K-12 classroom/s or engineering expert/s), using the engineering design process, to create collaborative engineering solutions (projects). Because of the social complexity of global K-12 collaborations in engineering, the efficacy of these endeavors varies. This paper proposes Activity theory (AT) as a theoretical framework to analyze global K-12 collaborations in engineering. The authors use AT, in the context of an elementary-level U.S./Thai global collaboration, to document the experience and describe the activity. Using student, teacher, and expert created documents from the collaboration, the efficacy of the activity (student learning outcomes) were evaluated and then applied to AT. The rules, division of labor and community were found as areas that presented challenges to achieving successful outcomes within the activity system. This paper provides classroom teachers a roadmap for designing more successful global collaborations for K-12 engineering and 21st century skill development

Patient Sociotechnical Assemblages: The Distributed Cognition of Health Information Management

Personal health records (PHR) are shifting the capabilities and responsibilities of both patients and providers. Influenced by health IT, concepts like patient-centered care, meaningful use, and patient empowerment are commonplace in the healthcare system. As the popularity of personal health records increases, medical providers, healthcare organizations, and health information system stakeholders require a thorough understanding of how patients use these patient facing information portals in conjunction with other artifacts, objects, and practices to manage and maintain their health. Exploring health information management as a distributed sociotechnical assemblage is the conceptual approach of this research. A distributed cognition perspective lends insight to drawing boundaries and establishing connections of personal health information management practices in conjunction with PHR use. The Department of Veterans Affairs provides a unique setting to further understand PHR use and personal health information management practice through the observation of U.S. military veterans enrolled in the My HealtheVet PHR. This context and conceptual framework lead to the research questions for the proposed study: RQ1a: What are the personal health information management practices of veterans who use a personal health record? RQ1b: What health information management practices become distributed beyond the veteran patient? RQ2a: What health information management assemblages emerge from the distributed work of Veterans that use a personal health record? RQ2b: What are key functions of the health information management assemblages of veterans? Through the use of semi-structured in depth interviews, observations, and surveys, data were collected on 22 patients along with their primary care providers and caretakers. Results from a two cycle qualitative coding analysis and analytical cognitive mapping technique reveal bundles of practices for creating reminders, organizing information, and creating information for asking questions and working with primary care providers. Distributed practices emerged that detail the managing of medication, information that is socially distributed, and patient-provider communication through secure messaging. Three health information management assemblage components emerged from the analysis: health events and experiential information, information techniques, and technology and material practices. Each of these components is understood by the ways they become stabilized or destabilized. This research contributes to implications for the design of patient-focused personal health records and informs clinical practice of patient-centered care. The research also makes conceptual and empirical contributions to the practice of health information management and a patient-centered care model of healthcare delivery
