    This is a multidisciplinary information systems thesis with a strong sociological focus. Theoretically it uses the technical concerns of human-computer interaction as the background to consider the separate theories of consumer decision-making and the diffusion of innovations. Emphasis is placed on understanding how consumers make sense of the Internet and come to define the role and use of the Internet in their lives. A practical framework for hermeneutic investigation was created to access the unreflective thoughts and actions driving online consumer decision-making. Implicit within hermeneutics is the prospect of transcendental interpretations and the ability to investigate in situ new avenues of research that emerge as a result of anomalous comments or findings. Hence, this thesis presents two different, but inter-related, research inquiries and their associated findings. Initial interest was centred on consumer behaviour and interface design. Specifically, can a dedicated 'consumer interface' be designed using principles based on consumer perceptions of online convenience. The resulting data analysis created a framework of advice that interface designers can use to improve their understanding of the nature and limitations of convenient interfaces and associated consumer decision-support technologies. A second research theme emerged from the data analysis which broadened the focus into a consideration of online consumer behaviour as a distinct issue. Specifically, a new from of interactive behaviour prevalent in electronic retail markets was identified and, following a second literature review, labeled "surrogacy". Related in form to the personal shoppers found in traditional marketplaces, surrogacy differs from electronic intermediaries with regard to (i) the motivations of use and (ii) the symbolic and functional benefits of usage. The emergence of this phenomenon suggests that interactions between individuals (as consumers) and Web-based systems are maturing, albeit in a non-predictable manner. Together, the methodological refinements presented here with the accompanying research findings provide a reference point for further work in the following three areas: interface design for electronic marketplaces; Web-based consumer decision support technologies; and the development of interpretive approaches suitable for socio-technical investigations.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

    VAST: A Human-Centered, Domain-Independent Video Analysis Support Tool

    Providing computer-aided support for human analysis of videos has been a battle of extremes. Powerful solutions exist, but they tend to be domain-specific and complex. The user-friendly, simple systems provide little analysis support beyond basic media player functionality. We propose a human-centered, domain-independent solution between these two points. Our proposed model and system, VAST, is based on our experience in two diverse video analysis domains: science and athletics. Multiple-perspective location metadata is used to group related video clips together. Users interact with these clip groups through a novel interaction paradigm ? views. Each view provides a different context by which users can judge and evaluate the events that are captured by the video. Easy conversion between views allows the user to quickly switch between contexts. The model is designed to support a variety of user goals and expertise with minimal producer overhead. To evaluate our model, we developed a system prototype and conducted several rounds of user testing requiring the analysis of volleyball practice videos. The user tasks included: foreground analysis, ambiguous identification, background analysis, and planning. Both domain novices and experts participated in the study. User feedback, participant performance, and system logs were used to evaluate the system. VAST successfully supported a variety of problem solving strategies employed by participants during the course of the study. Participants had no difficulty handling multiple views (and resulting multiple video clips) simultaneously opened in the workspace. The capability to view multiple related clips at one time was highly regarded. In all tasks, except the open-ended portion of the background analysis, participants performed well. However, performance was not significantly influenced by domain expertise. Participants had a favorable opinion of the system?s intuitiveness, ease of use, enjoyability, and aesthetics. The majority of participants stated a desire to use VAST outside of the study, given the opportunity

    Die Arbeit nimmt sich der textuellen Dimension des E-Commerce an. Grundlegende Hypothese ist die textuelle Gebundenheit von Information und Transaktion im Bereich des elektronischen Handels. Überall dort, wo Produkte und Dienstleistungen angeboten, nachgefragt, wahrgenommen und bewertet werden, kommen natürlichsprachige Ausdrücke zum Einsatz. Daraus resultiert ist zum einen, wie bedeutsam es ist, die Varianz textueller Beschreibungen im E-Commerce zu erfassen, zum anderen können die umfangreichen textuellen Ressourcen, die bei E-Commerce-Interaktionen anfallen, im Hinblick auf ein besseres Verständnis natürlicher Sprache herangezogen werden

    Beyond the Feed and Board: Holistic Principles for Expressive Web Curation

    Get PDF
    We develop holistic principles for expressive web curation through the iterative design and study of a new medium and system, IdeaMâché. Web curation is the process of gathering and assembling content into online exhibits. The linear organization of the feed - e.g., Facebook and Twitter - and board - e.g., Pinterest - constrains authors in expressing themselves. We conducted a field study of IdeaMâché with 472 undergraduate student users. Quantitative, qualitative, and visual data show how students expressed themselves and developed ideas. Interaction logs show how students utilized expressive operations. We analyze students' creative works with ideation metrics of curation. Interviews expose users' underlying motivations and experiences. Visual data is compelling. While iteratively designing IdeaMâché features in conjunction with the mixed methods data, we derive holistic design principles for media and systems supporting expressive web curation: direct clipping with context, diverse and heterogeneous media, freeform non-linear medium of assemblage, multi-scale organization, sketching as annotation, and novice-friendly direct manipulation command selection and parameter adjustment

    Re-examining and re-conceptualising enterprise search and discovery capability: towards a model for the factors and generative mechanisms for search task outcomes.

    Many organizations are trying to re-create the Google experience, to find and exploit their own corporate information. However, there is evidence that finding information in the workplace using search engine technology has remained difficult, with socio-technical elements largely neglected in the literature. Explication of the factors and generative mechanisms (ultimate causes) to effective search task outcomes (user satisfaction, search task performance and serendipitous encountering) may provide a first step in making improvements. A transdisciplinary (holistic) lens was applied to Enterprise Search and Discovery capability, combining critical realism and activity theory with complexity theories to one of the worlds largest corporations. Data collection included an in-situ exploratory search experiment with 26 participants, focus groups with 53 participants and interviews with 87 business professionals. Thousands of user feedback comments and search transactions were analysed. Transferability of findings was assessed through interviews with eight industry informants and ten organizations from a range of industries. A wide range of informational needs were identified for search filters, including a need to be intrigued. Search term word co-occurrence algorithms facilitated serendipity to a greater extent than existing methods deployed in the organization surveyed. No association was found between user satisfaction (or self assessed search expertise) with search task performance and overall performance was poor, although most participants had been satisfied with their performance. Eighteen factors were identified that influence search task outcomes ranging from user and task factors, informational and technological artefacts, through to a wide range of organizational norms. Modality Theory (Cybersearch culture, Simplicity and Loss Aversion bias) was developed to explain the study observations. This proposes that at all organizational levels there are tendencies for reductionist (unimodal) mind-sets towards search capability leading to fixes that fail. The factors and mechanisms were identified in other industry organizations suggesting some theory generalizability. This is the first socio-technical analysis of Enterprise Search and Discovery capability. The findings challenge existing orthodoxy, such as the criticality of search literacy (agency) which has been neglected in the practitioner literature in favour of structure. The resulting multifactorial causal model and strategic framework for improvement present opportunities to update existing academic models in the IR, LIS and IS literature, such as the DeLone and McLean model for information system success. There are encouraging signs that Modality Theory may enable a reconfiguration of organizational mind-sets that could transform search task outcomes and ultimately business performance

    Integrated Internet Marketing Communications for the Global Market: An Empirical Examination

    Strategy formulation, strategy implementation, and performance of Internet (online) marketing communications (IOMC) by companies when they attempt to target, reach, and communicate with the global market (i.e., both domestic and foreign markets) in order to promote and sell products to the members of that market was the broad phenomenon examined. The specific focus was on the use of a globally integrated marketing communications (GIMC) approach with IOMC and the creation of the global Internet integrated marketing communications (GI-IMC) concept. Relevant theories and theoretical models were identified and leveraged to serve as the theoretical foundation for the general theoretical framework, the research program framework, and/or the hypothesized conceptual model created and/or empirically examined at least partially. They included: industrial organization theory, the resource-based view, and the strategic fit paradigm (environment-strategy coalignment). In addition, various relevant research streams and concepts were described and examined in detail. They included: IOMC, international Internet marketing, integrated marketing communications, GIMC, and Internet integrated marketing communications. The Market Orientation construct was the lone independent variable or construct included in the initial four-construct model empirically examined. There were three stages of data collection: (1) pre-test, (2) pilot test, and (3) main test. A convenience sample of 73 academics or industry practitioners was utilized for the pre-test in order to make modifications to the survey instrument for subsequent rounds of data collection. Samples of qualified industry practitioners were then obtained for the pilot test (n=70) and main test (n=400) from online respondent panels provided by third-party vendors. Results included the creation of two new theoretical constructs (i.e., Global Internet Integrated Marketing Communications and Global Internet Marketing Communications Performance) and the formulation and preliminary validation of their measurement scales (though the hypothesized measurement model lacked discriminant validity, which prevented testing of the hypothesized structural model). In addition, a statistically significant positive relationship was found to exist between the Global Internet Integrated Marketing Communications construct and the Global Internet Marketing Communications Performance construct in a final two-construct model proposed and examined through post-hoc analysis. Implications of this research for researchers and practitioners are provided, as are future research directions

    Design Research For Personal Information Management Systems To Support Undergraduate Students

    This dissertation investigated the personal information management (PIM) behaviors and practices of undergraduate college students during a four month academic semester period. Qualitative data on the day-to-day PIM practices for 15 students enrolled in an honors biology class were collected through in-depth observations and interviews. Four students experimented with MyLifeBits--a next-generation PIM system developed at Microsoft Research. A participatory design session involving six students explored and identified new directions for PIM design. Analysis of the field data revealed that students engage regularly in project management activities, and their work is often highly collaborative. Students were observed to have difficulty with core PIM activities, such as managing tasks and reminders (and both PIM and technical skills vary widely among students). Students were observed to manage a diverse array of information formats, applications, and media, which are rarely integrated. Gaps in understanding and awareness among students and instructors were also noted. MyLifeBits was found to be intuitive and effective for visual browsing and refinding, although specific elements of the MyLifeBits user interface could likely be improved to support efficient task completion. The MyLifeBits system includes annotation, collection building, and other features that may support new approaches for making order and stimulating reflection. Observations of student usage suggested further design modifications to improve these features and supporting user interfaces. Implications for future research and design include: Incorporating social awareness and communication into PIM systems to help reduce gaps in understanding and facilitate reflection; integrating collaboration technologies into PIM systems to support students' highly collaborative work practices; providing tools to stimulate reflection (e.g., personal analytics) and create reflective artifacts (e.g., journals, multimedia scrapbooks); shifting the focus of design to outcomes (such as, "getting my assignment done on time, and in the way the teacher expects") that PIM supports rather than the PIM process itself; and developing ways to scaffold students' learning of PIM skills, such as metadata creation, project analysis and management, collaboration, and reflection
