    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.

    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.

    Towards Integrating Rationalistic and Ecological Design Methods for Interactive Systems
    (Georgia Institute of Technology, 1995) Hsi, Idris ; Potts, Colin
    Interactive systems design based on rationalistic methods can benefit from the integration of ecological methods that gather information about the user and the task environment. In this paper, we begin to discuss how such an integration of methods can be brought about and what benefits can be derived from it. Using meeting scheduling as an example, we show how workplace data gathering, in the form of user interviews, can significantly alter the specification of a collaborative interactive system. Our discussion of rationalistic methods is restricted to goal refinement approaches, and we discuss a series of design issues that are most pertinent in this approach, specifically: agency and responsibility, obstacle identification, obstacle avoidance and recovery, volume, frequency and repetitiveness issues, generic scenarios and critical incidents, artifact analysis, and deliberate fuzziness. However, we conclude by outlining how ecological methods could be integrated similarly with other rationalistic methods.

    Collaborative Pre-Writing with a Video-Based Group Working Memory
    (Georgia Institute of Technology, 1993) Potts, Colin ; Bolter, Jay David ; Badre, Albert N.
    Synthesis is a computer-controlled multimedia tool to enhance group communication during the early stages of collaborative work. Synthesis operates in two modes: one for recording collaborative sessions and one for playback and editing. A face-to-face meeting is recorded on video tape while one member of the group takes notes using Storyspace, an outline processor. Synthesis automatically associates the current video segment with that entry in the outline. Later one or more of the participants can review the notes and call up the appropriate video segment. Synthesis provides an external working memory for information that would otherwise go unrecorded and forgotten. Our early experiences using it for real writing projects suggests that the video record is used in a variety of ways to jog the writer's memory for discussion elements.
