  • Abstractions for designing and evaluating communication bridges for people in developing regions 

    Tucker, William David; Blake, Edwin H. (ACM, 2010)
    This paper describes two novel abstractions that help soft- ware engineers work in developing regions to align social and technical factors when building communication systems. The abstractions extend two concepts familiar ...
  • Bridging communications across the digital divide 

    Blake, Edwin H.; Tucker, William David (CTIT, 2004)
    Connecting people across the Digital Divide is as much a social effort as a technological one. We are developing a community-centered approach to learn how interaction techniques can compensate for poor communication across ...
  • Deaf telephony: community-based co-design 

    Blake, Edwin H.; Tucker, William David; Glaser, Meryl; Freudenthal, Adinda (Wiley, 2011)
    The process of community-based co-design is one that explores various solution configurations in a multi-dimensional design space whose axes are the different dimensions of requirements and the various dimensions of designer ...
  • Deaf telephony: community-based co-design (case study) 

    Blake, Edwin H.; Tucker, William David; Glaser, Meryl; Freudenthal, Adinda (Wiley, 2011)
    The process of community-based co-design is one that explores various solution configurations in a multi-dimensional design space whose axes are the different dimensions of requirements and the various dimensions of designer ...
  • Developing locally relevant applications for rural areas: a South African example 

    Chetty, Marshini; Tucker, William David; Blake, Edwin H. (SAICSIT, in assocation with ACM, 2004)
    The digital divide between rural and urban areas within developing countries is vast. We investigate how to address this divide by introducing Information and Communication Technologies (ICTs) into remote rural areas. Our ...
  • MUTI Telehealth 

    Tucker, William David; Vuza, Xolisa; Chetty, Marshini; Blake, Edwin H.; Marsden, Gary; Pearson, Murray; Westerveld, Rudi (2007)
    For four years we have been iteratively evolving MUTI, a rural telehealth system, for hospitals and clinics in a remote rural part of the Eastern Cape in South Africa (Chetty, 2005; Chetty et al., 2003, 2004a; Maunder et ...
  • Open user interconnect and quality of communication 

    Tucker, William David; Blake, Edwin H.; Marsden, Gary (Telkom, 2004)
    We looked for and found two situations within the South African Digital Divide where constant and severe macro-scale latencies would most likely interfere with the usage of Information and Communication Technology (ICT) ...
  • Reflection on three years of rural wireless Internet Protocol communication 

    Tucker, William David; Blake, Edwin H.; Marsden, Gary; Pearson, Murray; Westerveld, Rudi (Telkom, 2007)
    This paper reports on three years of research and fieldwork with a rural wireless Internet Protocol communication project. We built a long-range WiFi network and custom communication software to support a rural telehealth ...
  • The role of Outcome Mapping in developing a rural telemedicine system 

    Tucker, William David; Blake, Edwin H. (International Information Management Corporation, 2008)
    We describe the use of Outcome Mapping to guide the design of a rural telemedicine consultation system in South Africa. While Outcome Mapping was not primarily intended to guide design, we show that it tied in well with a ...
  • Socially aware software engineering for the developing world 

    Blake, Edwin H.; Tucker, William David (IIMC International Information Management Corporation, 2006)
    While the social effects of Information Technology (IT) have received much attention there is very little work on targeted methodologies to develop IT applications and content in a developing world environment. This paper ...
  • SoftBridge: a multimodal instant messaging bridging system 

    Lewis, John; Tucker, William David; Blake, Edwin H. (Telkom, 2003)
    Instant Messaging is traditionally a text only a air. However, there are instances when it would be useful to bridge to other types of media, like speech. The SoftBridge is an application framework that enables this kind ...
  • SoftBridge: an architecture for building IP-based bridges over the digital divide 

    Lewis, John; Tucker, William David; Blake, Edwin H. (Telkom, 2002)
    Users and computing equipment have varying capabilities that include the abilities to exchange text and audio, engage in high bandwidth communication, etc. As the technological options increase, e ective communication ...
  • Telemedicine using VoIP combined with a store and forward approach 

    Chetty, Marshini; Tucker, William David; Blake, Edwin H. (Telkom, 2004)
    Rural areas in South Africa have unique conditions such as remoteness and scarcity of reliable public facilities. Information and Communication Technologies (ICTs) introduced into these areas must be suitable for these ...
  • Towards communication and information access for deaf people 

    Blake, Edwin H.; Tucker, William David; Glaser, Meryl (SAICSIT, 2014)
    In tightly circumscribed communication situations, an interactive system resident on a mobile device can assist Deaf people with their communication and information needs. The Deaf users considered here use South African ...
  • User interfaces for communication bridges across the digital divide 

    Blake, Edwin H.; Tucker, William David (Springer-Verlag, 2006)
    Connecting people across the Digital Divide is as much a social effort as a technological one. We are developing a community-centred approach to learn how interaction techniques can compensate for poor communication across ...
  • Using voice over IP to bridge the digital divide: a critical action research approach 

    Chetty, Marshini; Tucker, William David; Blake, Edwin H. (Telkom, 2003)
    There is a great disparity between those who have access to Information and Communication Technologies (ICTs) and those that do not. This phenomenon forms part of the Digital Divide. Many ICTs may be used to help overcome ...
