    21st Century Liberal Arts
    ( 2016-12-02) Bankoff, Joe ; Goldbart, Paul ; Husbands Fealing, Kaye ; Laband, David ; Potts, Colin ; Royster, Jacqueline ; Stenport, Anna ; Usselman, Steven W. ; Utz, Richard ; Wepfer, William
    The ICLAST interdisciplinary research discussion series is designed to encourage research collaborations and to disseminate research to faculty, post doctoral fellows, and masters and undergraduate students across the College and campus. Panelists from different Georgia Tech units present their research on a common topic linking the liberal arts, sciences, and technology.

    STRAP: A Structured Analysis Framework for Privacy
    (Georgia Institute of Technology, 2005) Jensen, Carlos ; Tullio, Joseph ; Potts, Colin ; Mynatt, Elizabeth D.
    Privacy is an important concern for users, and a difficult design challenge. Different user populations have different requirements and expectations when it comes to privacy; thus finding universally acceptable solutions is far from trivial. Design guidelines have been available for a number of years, but often fail to address the dynamic and impromptu nature of privacy management. These methods also fail to provide a robust and replicable procedure for identifying potential problems, leaving the design process more in the realm of art than science. We identify general requirements for privacy-aware design and review how existing methods and guidelines meet these requirements. We then introduce a light-weight method adapted from the requirements engineering literature for the structured analysis of privacy vulnerabilities in design and the iterative adaptation of preferences. We present a study of this method on a predictive group calendar system.

    Private Policies Examined: Fair Warning or Fair Game?
    (Georgia Institute of Technology, 2003) Jensen, Carlos ; Potts, Colin
    Posting privacy policies has become a popular practice with businesses as they seek to shield themselves from potential liability or regulation, as well as inform users about their privacy and rights. These policies are in many ways modeled after software license statements, and are often more legalistic than user friendly. This paper examines the current practice of privacy policies as fair warning hold up from a usability perspective, and what steps can be taken to ensure that the average user can protect their privacy online.

    Towards a Framework for Hypermedia Scenarios
    (Georgia Institute of Technology, 1998) Hobbs, Reginald L. (Reginald Lionel) ; Potts, Colin
    Scenarios have been used in many disciplines, such as software engineering, cognitive science, and HCI (Human-Computer Interaction) to aid in decision making, comprehension, design, and training. Scenarios are instances of behavior of the systems, or "stories" about how the system will or should look. These scenarios are used largely as points of discussion in each of these cases. Building new scenarios or analyzing existing scenarios orient the discussion in collaborative activities and increase understanding in single user tasks. How can a scenario structure be defined that will support the widest range of discussion/comprehension activities and remain content- and access-independent? Scenarios can be structured as a document. In some ways, it is similar to a screenplay document from the film industry. The use of a markup language will allow scenario documents to take advantage of hypermedia representations of the components. Building appropriate tools to interpret the Scenario Markup Language (SCML) will support the creation of different representations of scenarios (such as storyboards, audiovisual segments, narratives, etc.) from the same data. Interactions between SCML and tool functionality will also support scenario authoring, dependency analysis, and structured walkthroughs.

    Coordination in Multi-Organization Creative Design Projects
    (Georgia Institute of Technology, 1998) Eastman, Charles M. ; Hsi, Idris ; Potts, Colin
    We are interested in the coordination of design and planning decisions in large, multi-organizational projects and their implications for technology support. These projects are undertaken by goal-driven "virtual organizations", involving companies of different sizes, professional traditions, cultures, as well as geographic location. We have observed several months of planning and review meetings in a multi-national architectural project and have gathered volumes of design and planning documentation in the form of memoranda, faxes, project plans and design drawings. From our observations, we outline the requirements and possible features of useful coordination support.

    Developing Voice-only Applications in the Absence of Speech Recognition Technology
    (Georgia Institute of Technology, 1997) Dey, Anind K. ; Catledge, Lara D. ; Abowd, Gregory D. ; Potts, Colin
    In this paper, we describe an information access system with a voice-only interface. We outline a design process for generating guidelines for voice-only interaction in the absence of adequate speech recognition technology. Our usability studies make use of a "Wizard of Oz" scheme to replace the missing core technology.
