    Glove-based tactile interfaces are used for augmented reality, rehabilitation, teaching, and consumer electronics control. Yet questions remain regarding perception of tactile stimuli on the hands. In an effort to inform ...
  • A Strategy for Addressing Ambiguity in Regulatory Requirements 

    Massey, Aaron K.; Rutledge, Richard L.; Antón, Annie I.; Hemmings, Justin D.; Swire, Peter P. (Georgia Institute of Technology, 2015)
    Ambiguities in legal texts can make the difference between regulatory compliance and non-compliance in software systems. Ambiguities are prevalent in laws and regulations. Policy analysts who write laws and regulations ...
  • Defining the Internet of Devices: Privacy and Security Implications 

    Rutledge, Richard L.; Massey, Aaron K.; Antón, Annie I.; Swire, Peter (Georgia Institute of Technology, 2014-06)
    What observers have called the Internet of Things (IoT) presents privacy and security challenges for contemporary society. The conceptual model of the IoT evolved rapidly from technologies used to track parts in industrial ...
  • Can I Wash It? : The Effect of Washing Conductive Materials Used in Making Textile Based Wearable Electronic Interfaces 

    Zeagler, Clint; Gilliland, Scott; Audy, Stephen; Starner, Thad (Georgia Institute of Technology, 2013)
    In this paper we explore the wash-ability of conductive materials commonly use in creating traces and touch sensors in wearable electronic textile systems. We performed a wash test measuring change in resistivity ...
  • Visualization of Exception Handling Constructs to Support Program Understanding 

    Shah, Hina; Görg, Carsten; Harrold, Mary Jean (Georgia Institute of Technology, 2009)
    This paper presents a new visualization technique for supporting the understanding of exception-handling constructs in Java programs. To understand the requirements for such a visualization, we surveyed a group of software ...
