    No full text
    A Technology Enhanced Interaction Framework has been developed to support designers and developers design and develop technology enhanced interactions for complex scenarios involving disabled people. Issues of motivation, time, and understanding when validating and evaluating the Technology Enhanced Interaction Framework were identified through a literature review and questionnaires and interviews with experts. Changes to content, system, and approach were made in order to address the identified issues. Future work will involve detailed analysis of the expert review and validation findings and the implementation of a motivating approach to user evaluation

    To address the question on how to enhance the design of user-artefact interaction at the initial stages of the design process, this study focuses on exploring the differences between designers and users in regard to their concepts of an artefact usage. It also considers that human experience determines people’s knowledge and concepts of the artefacts they interact with, and broadens or limits their concept of context of use. In this exploratory study visual representation of concepts is used to elicit information from designers and users, and to explore how these concepts are influenced by their individual experience. Observation, concurrent verbal and retrospective protocols and thematic interviews are employed to access more in depth information about users’ and designers’ concepts. The experiment was conducted with designers and users who were asked about their concepts of an everyday product. Three types of data were produced in each session: sketches, transcriptions from retrospectives verbal reports and observations. Through an iterative process, references about context, use and experience were identified in the data collected; this led to the definition of a coding system of categories that was applied for the interpretation of visuals and texts. The methodology was tested through preliminary studies. Their initial outcomes indicate that the main differences between designers’ and users’ concepts come from their knowledge domain, while main similarities are related to human experience as source that drives concept formulation. Cultural background has been found to influence concepts about product usability and its context of use. The use of visual representation of concepts with retrospective reports and interviews allowed access to insightful information on how human experience influence people’s knowledge about product usability and its context of use. It is expected that this knowledge contributes to the enhancement of the design of product usability

    Designerly Tools

    An assumption behind this paper is that research aimed at improving interaction design practice is not as successful as it could be. We will argue that one reason for this is that the understanding of what constitutes designerly tools is not enough recognized among those who propose new tools for interaction design. We define designerly tools as methods, tools, techniques, and approaches that support design activity in way that is appreciated by practicing interaction designers. Based on a two empirical studies, we have developed a framework and a way of studying designers and their tools. We discuss some insights about what characterizes designerly tools and what kind of implications these insights might have for the further development of tools aimed at supporting design practice.

    Building a Common Ground – The Use of Design Representation Cards for Enhancing Collaboration between Industrial Designers and Engineering Designers

    Get PDF
    To achieve success in today’s commercial environment, manufacturers have progressively adopted collaboration strategies. Industrial design has been increasingly used with engineering design to enhance competitiveness. Research between the two fields has been limited and existing collaboration methods have not achieved desired results. This PhD research project investigated the level of collaboration between industrial designers and engineering designers. The aim is to develop an integration tool for enhanced collaboration, where a common language would improve communication and create shared knowledge. An empirical research using questionnaires and observations identified 61 issues between industrial designers and engineering designers. The results were grouped and coded based on recurrence and importance, outlining 3 distinct problem categories in collaborative activity: conflicts in values and principles, differences in design representation, and education differences. A taxonomy further helped categorise design representations into sketches, drawings, models and prototypes. This knowledge was indexed into cards to provide uniform definition of design representations with key information. They should benefit practitioners and educators by serving as a decision-making guide and support a collaborative working environment. A pilot study first refined the layout and improved information access. The final validation involving interviews with practitioners revealed most respondents to be convinced that the tool would provide a common ground in design representations, contributing to enhanced collaboration. Additional interviews were sought from groups of final-year industrial design and engineering design students working together. Following their inter-disciplinary experience, nearly all respondents were certain that the cards would provide mutual understanding for greater product success. Lastly, a case study approach tested the cards in an industry-based project. A design diary captured and analysed the researchers’ activities and observations on a daily basis. It revealed positive feedback, reinforcing the benefits of the cards for successful collaboration in a multi-disciplinary environment.

    Design Research on Robotic Products for School Environments

    Get PDF
    Advancements in robotic research have led to the design of a number of robotic products that can interact with people. In this research, a school environment was selected for a practical test of robotic products. For this, the robot “Tiro” was built, with the aim of supporting the learning activities of children. The possibility of applying robotic products was then tested through example lessons using Tiro. To do this, the robot design process and user-centred HRI evaluation framework were studied, and observations of robotic products were made via a field study on the basis of these understandings. Three different field studies were conducted, and interactions between children and robotic products were investigated. As a result, it was possible to understand how emotional interaction and verbal interaction affect the development of social relationships. Early results regarding this and coding schemes for video protocol analysis were gained. In this preliminary study, the findings are summarized and several design implications from insight grouping are suggested. These will help robot designers grasp how various factors of robotic products may be adopted in the everyday lives of people. Keywords: Robotic Products Design, HRI Evaluation, User-Centered HRI.</p

    Participatory Scenario Generation: Communicating Usability Issues in Product Design through User Involvement in Scenario Generation\ud

    Get PDF
    Scenarios have proven to be a valuable tool in evaluating and communicating usability issues in consumer product design. Scenarios are explicit descriptions of hypothetical use situations. Realistic scenarios can serve as a valuable frame of reference to evaluate design solutions with regard to usability. To be able to achieve this required level of realism, involving users in scenario generation is essential. In this presentation we discuss how and where users can be involved in a scenario based product design process by means of examples of design projects that were executed by master students Industrial Design Engineering of the University of Twente. \ud \ud We distinguish direct and indirect scenario generation. In direct scenario generation the user is actively involved in a participatory scenario generation session: the scenarios are created together with users. Indirect scenario generation is an approach in which scenarios are created by designers based on common analysis techniques like observations and interviews. These scenarios are then offered to users for confirmation. Both types of user involvement in scenario generation can be aimed at either current use scenarios which describe the current situation or future use scenarios which include a new product design. \ud \ud The examples show that all strategies can be applied successfully to create realistic scenarios. Which strategy to choose depends among others upon risks and privacy issues, occurrence of infrequent events and availability of users. Furthermore, the variety of approaches shows that there is still a lot to explore with regard to benefits and limitations of the many techniques that can be applied in generating scenarios for consumer product design. We hope to contribute to this field by means of the research in our group and the work of students in the SBPD course\u

    Reflecting on the usability of research on culture in designing interaction

    Get PDF
    The concept of culture has been attractive to producers of interactive\ud systems who are willing to design useful and relevant solutions to users\ud increasingly located in culturally diverse contexts. Despite a substantial body of\ud research on culture and technology, interaction designers have not always been\ud able to apply these research outputs to effectively define requirements for\ud culturally diverse users. This paper frames this issue as one of understanding of\ud the different paradigms underpinning the cultural models being applied to\ud interface development and research. Drawing on different social science theories,\ud the authors discuss top-down and bottom-up perspectives in the study of users‟\ud cultural differences and discuss the extent to which each provides usable design\ud knowledge. The case is made for combining bottom-up and top-down perspectives\ud into a sociotechnical approach that can produce knowledge useful and usable by\ud interaction designers. This is illustrated with a case study about the design of\ud interactive systems for farmers in rural Kenya

    A Study of the Role of Visual Information in Supporting Ideation in Graphic Design

    Get PDF
    Existing computer technologies poorly support the ideation phase common to graphic design practice. Finding and indexing visual material to assist the process of ideation often fall on the designer, leading to user experiences that are less than ideal. To inform development of computer systems to assist graphic designers in the ideation phase of the design process, we conducted interviews with 15 professional graphic designers about their design process and visual information needs. Based on the study, we propose a set of requirements for an ideation-support system for graphic design
