    Designing a Cognitive Aid for the Home: A Case-Study Approach
    (Georgia Institute of Technology, 2004) Paradise, Jessica ; Mynatt, Elizabeth D. ; Williams, Cliff ; Goldthwaite, J. R., III (John R.)
    Cognitive impairments play a large role in the lives of surviviors of mild traumatic brain injuries who are unable to return to their prior level of independence in their homes. Computational support has the potential to enable these individuals to regain control over some aspects of their lives. Our research aims to carefully seek out issues that might be appropriate for computational support and to build enabling technologies that increase individuals functional independence in the home environment. Using a case-study approach, we explored the needs and informed the design of a pacing aid for an individual with a cognitive impairment whose quality of life was negatively affected by her inability to pace herself during her morning routine. The contributions of this research include insights we gained with our methodology, two sets of design dimensions: user-centered contraints developed from capabilities and preferences of our users and system-centered capabilities that could be explored in potential designs, a design concept which illustrates the application of these design dimensions into a potential pacing aid, and evaluations of paper prototypes guided by the design dimensions.

    Supporting Privacy Management via Community Experience and Expertise
    (Georgia Institute of Technology, 2004) Goecks, Jeremy ; Mynatt, Elizabeth D.
    We propose a novel approach for supporting privacy management that leverages community experience and expertise via the process of social navigation. Social navigation simplifies the often complex task of managing privacy settings, and systems that employ social navigation can advantageously complement user privacy management processes. We implemented our approach to privacy management in the Acumen system; Acumen uses social navigation to enable individuals to manage their Internet cookies both manually and automatically based on the behavior of others in the community. We present the Acumen system in detail and discuss data obtained from a six-week, preliminary deployment of Acumen. Lastly, we discuss challenges that systems implementing our approach must address if they are to be successful.

    What Was I Cooking? Towards Deja Vu Displays of Everyday Memory
    (Georgia Institute of Technology, 2003) Tran, Quan T. ; Mynatt, Elizabeth D.
    The recall of information associated with recent actions is problematic for all people, especially when one is prone to be distracted or interrupted. In this paper, we introduce Deja Vu Displays as resources for everyday memory recall. These displays augment "knowledge in the head" by visually displaying recent events as "knowledge in the world." As an initial study, we present the design and evaluation of the Cook's Collage, a memory aid for cooking. Our initial studies indicate that people can benefit from this everyday memory aid, and that further exploration of the design and implementation of these displays is warranted.

    Privacy Mirrors: Understanding and Shaping Socio-technical Ubiquitous Computing Systems
    (Georgia Institute of Technology, 2002) Nguyen, David H. ; Mynatt, Elizabeth D.
    Privacy is a known issue in ubiquitous computing, exasperated by an oft-cited feature of ubiquitous computing - invisibility. Dangers of invisible computing are interfaces that do not give people the needed tools of awareness and control to understand and shape the behavior of the system. By definition, ubiquitous computing systems are socio-technical, encompassing three environments: social, technical, and physical. We argue that addressing or presenting solutions in any one environment alone cannot solve the privacy issue in ubiquitous computing. Privacy is addressed best by giving users methods, mechanisms, and interfaces to understand and then shape the system in all three environments. We introduce Privacy Mirrors, a framework for designing socio-technical ubiquitous computing systems that will integrate into people's on-going needs, practices, values, and aesthetic sensibilities.

    Ten Inch Pixels: Ambient Art for Remote Awareness
    (Georgia Institute of Technology, 2001) Mankoff, Jennifer C. ; Rowan, James Thomas, Jr. ; Mynatt, Elizabeth D. ; McJunkin, Mark P.
    We present an ambient display for supporting social connections between extended family members. The display, a digitally-controlled combination of oil on canvan and mechanical sculpture, consists of four, ten-by-ten inch "pixels", supporting the display of five coherent images and hundreds of mixed, collage images.

    Dynamic Door Displays
    (Georgia Institute of Technology, 2000) Nguyen, David H. ; Tullio, Joseph ; Drewes, Tom ; Mynatt, Elizabeth D.
    Traditionally, office doors have been used as display surfaces for communicating a variety of information between door owners and visitors. While flexible, doors also burden their owners with the task of maintenance and do not support notions of public and private information. In this paper we introduce the Dynamic Door Display, a tool for enhancing an office door's display capabilities to include automatic updates and tailored displays of private information for particular visitors. This work is based on an initial qualitative study of personalized location-specific information.

    Ictus: A User-Centered System of Score Study for Semi-Novice Conductors
    (Georgia Institute of Technology, 2000) Mitchell, Amy ; Voida, Stephen ; Paradise, Jessica ; Martin, Chris C. ; Mynatt, Elizabeth D.
    Ictus supports the study and preparation of musical scores by semi-novice conductors. It does so by representing the complex analytical processes in which professional conductors routinely engage. Through iterative design and prototyping and with feedback from expert conductors, we have developed a prototyped system for use as a learning tool. This paper presents a brief overview of the complexities of the conductor's task, including the difficulties inherent in externalizing it; a description of the Ictus system; and a discussion of some of the feedback and forward-looking issues that have been raised.
