Applying a User-centred Approach to Interactive Visualization Design

Analysing users in their context of work and finding out how and why they use different information resources is essential to provide interactive visualisation systems that match their goals and needs. Designers should actively involve the intended users throughout the whole process. This chapter presents a user-centered approach for the design of interactive visualisation systems. We describe three phases of the iterative visualisation design process: the early envisioning phase, the global specification hase, and the detailed specification phase. The whole design cycle is repeated until some criterion of success is reached. We discuss different techniques for the analysis of users, their tasks and domain. Subsequently, the design of prototypes and evaluation methods in visualisation practice are presented. Finally, we discuss the practical challenges in design and evaluation of collaborative visualisation environments. Our own case studies and those of others are used throughout the whole chapter to illustrate various approaches

Creating Reusable Educational Components: Lessons from DLESE

Reuse of educational materials is integral to many educator tasks, from designing a course to preparing for a lab or class. This article describes a study on the reuse of educational materials in the context of the Digital Library for Earth System Education (DLESE), a community-owned and governed facility offering high-quality teaching and learning resources for Earth system education. The study noted that educational resource designers often do not develop components with reuse in mind, making it more difficult or impossible for other educators to find and use their material, and that the 'findability' and reusability of community-created digital educational resources is highly dependent on the presentational and structural design of the resources themselves. The authors recommend that all resources clearly state the creator's name and contact information, relevant copyright restrictions, the most significant date for the resource (specifying creation or revision), and the intended grade level.

An investigation into the perspectives of providers and learners on MOOC accessibility

An effective open eLearning environment should consider the target learner’s abilities, learning goals, where learning takes place, and which specific device(s) the learner uses. MOOC platforms struggle to take these factors into account and typically are not accessible, inhibiting access to environments that are intended to be open to all. A series of research initiatives are described that are intended to benefit MOOC providers in achieving greater accessibility and disabled learners to improve their lifelong learning and re-skilling. In this paper, we first outline the rationale, the research questions, and the methodology. The research approach includes interviews, online surveys and a MOOC accessibility audit; we also include factors such the risk management of the research programme and ethical considerations when conducting research with vulnerable learners. Preliminary results are presented from interviews with providers and experts and from analysis of surveys of learners. Finally, we outline the future research opportunities. This paper is framed within the context of the Doctoral Consortium organised at the TEEM'17 conference

Towards the design of a kid’s music organizer

In this paper, we investigate how young children aged 2 to 5 interact with music and their family's music collections. By going into their homes, interviewing them and their parents and observing the children performing a range of music-related tasks, we explore the way that pre-school children select, interact with, and organize music. Additionally, drawing tasks were included in the visits to engage the children and allow them to demonstrate their thoughts in a concrete manner. Insights into the children's' music behaviours suggest design features for a music organizer / player for very young children

Information systems evaluation methodologies

Due to the prevalent use of Information Systems (IS) in modern organisations nowadays, evaluation research in this field is becoming more and more important. In light of this, a set of rigorous methodologies were developed and used by IS researchers and practitioners to evaluate the increasingly complex IS implementation used. Moreover, different types of IS and different focusing perspectives of the evaluation require the selection and use of different evaluation approaches and methodologies. This paper aims to identify, explore, investigate and discuss the various key methodologies that can be used in IS evaluation from different perspectives, namely in nature (e.g. summative vs. formative evaluation) and in strategy (e.g. goal-based, goal-free and criteria-based evaluation). The paper concludes that evaluation methodologies should be selected depending on the nature of the IS and the specific goals and objectives of the evaluation. Nonetheless, it is also proposed that formative criteria-based evaluation and summative criteria-based evaluation are currently among the most and more widely used in IS research. The authors suggest that the combines used of one or more of these approaches can be applied at different stages of the IS life cycle in order to generate more rigorous and reliable evaluation outcomes

A framework for the adoption and diffusion of Personal Learning Environments in commercial organisations: an exploratory study in the learning and development sector in the UK

This study presents an exploratory approach to identify the main factors of Personal Learning Environment (PLE) adoption and diffusion within commercial organisations. Utilising an inductive investigative approach via the use of Grounded Theory methodology, relevant adoption factors were identified and their resulting influence during various stages of the innovation diffusion process were proposed. Data was collected using semi-structured interviews followed by systematic analysis using a three-staged coding process. The results revealed 10 factors affecting the adoption of PLEs influencing the innovation diffusion process at various stages. Informed by the Technology Acceptance Model and Innovation Diffusion Theory, the proposed model could have important implications for key decision makers within commercial organisations, while adopting, rejecting and assimilating new technological innovations (e.g. PLE) for learning delivery

Characterizing the Application of Design Ethnography Techniques to Improve Novice Human-Centered Design Processes.

Design is a central, distinguishing feature of engineering, requiring the development of technical solutions to societal problems. Successful design solutions must not only be technically sound, but also well-adapted to the context and culture in which they will be used. However, the most commonly used methods for eliciting and characterizing stakeholder preferences do not typically reveal critical stakeholder and contextual information. Through the studies described in this dissertation, I explore the use of design ethnography during front-end engineering design phases to capture both stakeholder preferences and contextual knowledge to inform engineering design decision making. Design ethnography is a set of primarily qualitative data collection and analysis techniques that have been adapted from the field of anthropology to augment the engineering design process. Studies from the fields of human-computer interaction and product development have demonstrated that design ethnography techniques are cost-effective and lead to more successful products. However, the design ethnography literature lacks critical understanding of the major barriers and factors that influence design ethnography success, methodologies for synthesizing and applying design ethnography data, best practices to engage with stakeholders, developmental trajectories of novice to expert skill acquisition, and case studies of how design ethnography has been implemented in diverse settings. The studies detailed in this dissertation employ a mixture of quantitative and qualitative research methods to address these gaps in the literature. Through this research, I have characterized novice design ethnography implementation strategies and identified internal and external factors that affect design ethnography execution; investigated correlations between information processing ability and the quality of product requirements developed; established a framework for evaluating and directing design ethnography stakeholder interviews; developed a case study within a global health design context; and interpreted the findings within a theoretically grounded model to represent novice to expert development. This body of work informs strategies and processes for engaging with stakeholders and understanding broader contexts in design work to improve design decision making within both design professional practice and engineering education.PhDMechanical EngineeringUniversity of Michigan, Horace H.
