    TENSE Ball: A Smart Therapeutic Squeeze Ball to Monitor Hand Activities and Patients’ Pain and Stress Level
    (Georgia Institute of Technology, 2021-03) Shahmiri, Fereshteh ; Schwartz, Steven ; Usanmaz, Can ; Inan, Omer T. ; Edwards, W. Keith
    Hand dexterity, grip strength, and fine motor control are important to our daily routines but can be severely impacted by the development of prognoses such as Parkinson’s disease, Arthritis, recoveries after stroke, surgery, or coma. Simple yet effective squeeze ball exercises have been shown to accelerate recovery, restore mobility, and reduce pain. Hence, there is a need to monitor patient performance and compliance with respect to these exercises along with additional assessments of pain and stress levels. Commercially available hand exercising balls do not provide quantitative data, which is crucial for assessing patient performance and pain level as well as informing clinicians for proper treatment. To the best of our knowledge, there is no single device in the market or existing research domains, with a flexible form factor that can identify the gripping patterns and correctness of the performed therapeutic exercises as well as assess the pain level that patient is experiencing before and after those exercises. Hence, we designed TENSE ball, a triboelectric nanogenerator-based squeezable electronic ball that is computationally capable of addressing discussed problems, while maintaining the innate features as its non-computational counterparts. The major contributions of our design include first, capturing psycho-physiological data utilizing an Electro-dermal Activity (EDA) sensor. Second, it monitors the biomechanical status of hand motions and dexterity to assess the correctness of the patient’s performed therapeutic exercises and tracks compliance and improvement with time. Third, it detects hand tremors and other involuntary motion artifacts which allows for the capturing of valuable patient prognostic information.

    inSpace: Co-Designing the Physical and Digital Environment to Support Workplace Collaboration
    (Georgia Institute of Technology, 2008) Voida, Stephen ; McKeon, Matt ; Le Dantec, Christopher A. ; Forslund, C. ; Verma, Puja ; McMillan, B. ; Bunde-Pedersen, J. ; Edwards, W. Keith ; Mynatt, Elizabeth D. ; Mazalek, Ali
    In this paper, we unpack three themes for the multidisciplinary codesign of a physical and digital meeting space environment in supporting collaboration: that social practices should dictate design, the importance of supporting fluidity, and the need for technological artifacts to have a social voice. We describe a prototype meeting space named inSpace that explores how design grounded in these themes can create a user-driven, information-rich environment supporting a variety of meeting types. Our current space includes a table with integrated sensing and ambient feedback, a shared wall display that supports multiple concurrent users, and a collection of storage and infrastructure services for communication, and that also can automatically capture traces of how artifacts are used in the space.

    An Architecture for Transforming Graphical Interfaces
    (Georgia Institute of Technology, 1995) Edwards, W. Keith ; Mynatt, Elizabeth D.
    While graphical user interfaces have gained much popularity in recent years, there are situations when the need to use existing applications in a nonvisual modality is clear. Examples of such situations include the use of applications on hand-held devices with limited screen space (or even no screen space, as in the case of telephones), or users with visual impairments. We have developed an architecture capable of transforming the graphical interfaces of existing applications into powerful and intuitive nonvisual interfaces. Our system, called Mercator, provides new input and output techniques for working in the nonvisual domain. Navigation is accomplished by traversing a hierarchical tree representation of the interface structure. Output is primarily auditory, although other output modalities (such as tactile) can be used as well. The mouse, an inherently visually-oriented device, is replaced by keyboard and voice interaction. Our system is currently in its third major revision. We have gained insight into both the nonvisual interfaces presented by our system and the architecture necessary to construct such interfaces. This architecture uses several novel techniques to efficiently and flexibly map graphical interfaces into new modalities.

    Providing Access to Graphical User Interfaces - Not Graphical Screens
    (Georgia Institute of Technology, 1995) Edwards, W. Keith ; Mynatt, Elizabeth D. ; Stockton, Kathryn
    The 1990 paper "The Graphical User Interface: Crisis, Danger and Opportunity" summarized an overwhelming concern expressed by the blind community: a new type of visual interface threatened to erase the progress made by the innovators of screen reader software. Such software (as the name implies) could read the contents of a computer screen, allowing blind computer users equal access to the tools used by their sighted colleagues. Whereas ASCII-based screens were easily accessible, new graphical interfaces presented a host of technological challenges. The contents of the screen were mere pixel values, the on or off "dots" which form the basis of any bit-mapped display. The goal for screen reader providers was to develop new methods for bringing the meaning of these picture-based interfaces to users who could not see them. The crisis was imminent. Graphical user interfaces were quickly adopted by the sighted community as a more intuitive interface. Ironically, these interfaces were deemed more accessible by the sighted population because they seemed approachable for novice computer users. The danger was tangible in the forms of lost jobs, barriers to education, and the simple frustration of being left behind as the computer industry charged ahead. Much has changed since that article was published. Commercial screen reader interfaces now exist for two of the three main graphical environments. Some feel that the crisis has been adverted, that the danger is now diminished. But what about the opportunity? Have graphical user interfaces improved the lives of blind computer users? The simple answer is not very much. This opportunity has not been realized because current screen reader technology provides access to graphical screens, not graphical interfaces. In this paper, we discuss the historical reasons for this mismatch as well as analyze the contents of graphical user interfaces. Next, we describe one possible way for a blind user to interact with a graphical user interface, independent of its presentation on the screen. We conclude by describing the components of a software architecture which can capture and model a graphical user interface for presentation to a blind computer user.

    Intermezzo Implementation Notes
    (Georgia Institute of Technology, 1993) Edwards, W. Keith
    A collaboration support environment is a software system which developers can build on top of to provide more robust and flexible collaborative operations. This paper describes the architecture of the Intermezzo collaboration support environment. Intermezzo is a set of libraries, servers, and conventions which developers can use to construct collaborative applications. Intermezzo does not attempt to provide support for all aspects of collaborative software development. Instead, it restricts itself to providing support for the sharing of "facilitating data." Facilitating data is data which is used by applications and the collaboration support environment itself to facilitate the process of collaboration. An example of facilitating data is information about which users are currently active in collaborations. Facilitating data is distinct from artifacts. Artifacts are the actual data of discourse or concern of the collaborative process. As an example, the text document which is edited by a shared word processor is an artifact. Intermezzo does not provide facilities to support the sharing and use of artifacts.

    The Mercator Environment: A Nonvisual Interface to X Windows and Unix Workstations
    (Georgia Institute of Technology, 1992) Mynatt, Elizabeth D. ; Edwards, W. Keith
    User interfaces to computer workstations are heavily dependent on visual information. These Graphical User Interfaces, commonly found on powerful desktop computers, are almost completely inaccessible to blind and visually impaired individuals. In order to make these types of computers accessible to non-sighted users, it will be necessary to develop a new interface which replaces the visual communication with audio and tactile communication. This paper describes the Mercator Environment--an auditory and tactile interface to X Windows and Unix workstations designed for the visually impaired.
