  • End-user programming in time : implementation and empirical studies

    Creator:
    Arredondo-Castro, Miguel A.
    Abstract:
    The temporal behavior in applications involving visual data can be critical for the correctness of some programs. Forms/3 allows the user to specify temporal behaviors in an independent way, without introducing extraneous code in the original spreadsheet, whereas some other languages define new language devices specific to time. In this...

  • End-user assertions : propagating their implications

    Creator:
    Summet, Jay W.
    Abstract:
    Spreadsheet languages are the most commonly used end-user programming paradigm, yet spreadsheets commonly contain errors. Research shows that a significant number of spreadsheets (20%-40%) created by end users contain errors. In an attempt to reduce this error rate, this work presents an assertion propagation system for an end-user spreadsheet programming...

  • Temporal programming in grid-oriented visual programming languages

    Creator:
    Cao, Nanyu
    Abstract:
    Specifying varying speeds and temporal relationships is necessary when programming graphical animations, but support for temporal programming has usually been done by adding new language features to a Visual Programming Language (VPL), and these features must be mastered over and above the other aspects of the VPL. However, some researchers...

  • Personalizing machine learning systems with explanatory debugging

    Creator:
    Kulesza, Todd
    Abstract:
    How can end users efficiently influence the predictions that machine learning systems make on their behalf? Traditional systems rely on users to provide examples of how they want the learning system to behave, but this is not always practical for the user, nor efficient for the learning system. This dissertation...

  • Similarity inheritance : a model of inheritance for declarative visual programming languages

    Creator:
    Djang, Rebecca W. (Rebecca Walpole)
    Abstract:
    Declarative visual programming languages (VPLs), including spreadsheets, make up a large portion of both research and commercial VPLs. Spreadsheets in particular enjoy a wide audience, including end users. Unfortunately, spreadsheets and most other declarative VPLs still suffer from some of the problems that have been solved in other languages, such...

  • Generalizing abstractions in form-based visual programming languages : from direct manipulation to static representation

    Creator:
    Yang, Sherry
    Abstract:
    We believe concreteness, direct manipulation and responsiveness in a visual programming language increase its usefulness. However, these characteristics present a challenge in generalizing programs for reuse, especially when concrete examples are used as one way of achieving concreteness. In this thesis, we present a technique to solve this problem by...
