  • Understanding and supporting end-user debugging strategies

    Creator:
    Grigoreanu, Valentina I.
    Abstract:
    End users' programs are fraught with errors, costing companies millions of dollars. One reason may be that researchers and tool designers have not yet focused on end-user debugging strategies. To investigate this possibility, this dissertation presents eight empirical studies and a new strategy-based end-user debugging tool for Excel, called StratCel....

  • 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...

  • 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...

  • 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...

  • A methodology for testing spreadsheet grids

    Creator:
    Sheretov, Andrei
    Abstract:
    Although there has been research into ways to design spreadsheet systems to improve the processes of creating new spreadsheets and of understanding existing ones, little attention has been given to helping users of these environments test their spreadsheets. To help address this need, we introduce two visual approaches to testing...

  • 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...

  • Graphical definitions : expanding spreadsheet languages through direct manipulation and gestures

    Creator:
    Gottfried, Herkimer John
    Abstract:
    Until now, attempts to extend the one-way constraint evaluation model of the spreadsheet paradigm to support complex objects, such as colored circles or user-defined types, have led to approaches featuring either a direct way of creating objects graphically or strong compatibility with the spreadsheet paradigm, but not both. This inability...

  • Version Control Systems: An Information Foraging Perspective

    Creator:
    Srinivasa Ragavan, Sruti
    Abstract:
    Software history and version control systems (VCS) are an important source of information for developers. This entails the need for a principled understanding of developers’ information seeking in VCS, both for improving existing tools as well as understanding requirements for new tools. However, it is only recently that researchers have...

  • 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...

  • The InclusiveMag Method: A Start Towards More Inclusive Software for Diverse Populations

    Creator:
    Mendez, Christopher
    Abstract:
    How can software practitioners assess whether their software supports diverse users? Although there are empirical processes that can be used to find “inclusivity bugs” piecemeal, what is often needed is a systematic inspection method to assess software’s support for diverse populations. To help fill this gap, this thesis introduces InclusiveMag,...
