Recent Submissions

  • Video Relay Service for Deaf people using WebRTC 

    Henney, Andre J; Tucker, William D (University of the Western Cape, 2019-03)
    This paper reports on an experimental open source video relay service prototype that helps Deaf people communicate with hearing people by accessing a third party sign language interpreter on a mobile device. Deaf people ...
  • Mobile video comparison to help Deaf people make informed choices: a South African case study with provincial data 

    Henney, Andre; Tucker, William David (IIMC International Information Management Corporation, 2018)
    Deaf people use sign language to communicate and use mobile video calling to communicate with one another. Mobile video utilises much more bandwidth than text and voice communication modes, resulting in higher expenditure ...
  • Battery and data drain of over-the-top applications on low-end smartphones 

    Om, Shree; Tucker, William David (IIMC International Information Management Corporation, 2018)
    Low-end smartphones with sub $50 price tags provide affordable device ownership to low-income populations. However, their limited capacity, when combined with the need for multimodal connectivity, raises usage concerns in ...
  • Amplifying positive deviance with ICT enabling community development and interdependence 

    Tucker, William David (Springer, 2017)
    Positive deviance is a social mechanism whereby a beneficial practice that is not considered as normal gets taken up and spread within a community. This enables a community to solve its own problems aided by mentorship and ...
  • Walking and the social life of solar charging in rural Africa 

    Bidwell, Nicola J.; Siya, Masbulele Jay; Marsden, Gary; Tucker, William David; Tshemese, M.; Gaven, N.; Ntlangano, Senzo; Robinson, Simon; Eglinton, Kristen Ali (Association for Computing Machinery, 2013)
    We consider practices that sustain social and physical environments beyond those dominating sustainable HCI discourse. We describe links between walking, sociality, and using resources in a case study of community-based, ...
  • Development consortium: HCI across borders 

    Tucker, William David (Association for Computing Machinery, 2016)
    Though every country and context is unique, and much of HCI research aims to design for situatedness, there are lessons to be learned across borders, across contexts. Questions we ask include: What are common themes ...
  • Making a community network legal within the South African regulatory framework 

    Rey-Moreno, Carlos; Tucker, William David; Cull, Domonic; Blom, R. (ACM, 2015)
    Community networks often operate at the fringe of legality with respect to spectrum, network infrastructure and providing services. We have been involved with such a network in a rural community, and together with them, ...
  • Towards a scalability model for wireless mesh networks 

    Om, Shree; Rey-Moreno, Carlos; Tucker, William David (Telkom, 2015)
    Zenzeleni mesh network is a wireless ad-hoc mesh network that provides voice services using public analogue telephones to the Mankosi community in the Eastern Cape Province. We would like to improve on the network ...
  • Beyond traditional ethics when developing assistive technology for and with deaf people in developing regions 

    Tucker, William David (Springer, 2015)
    There are limitations to traditional ethical approaches and procedures when engaged in assistive technology (AT) research for Deaf people in a developing region. Non-traditional issues arise as a consequence of employing ...
  • Clustered Multi-layer Multi-protocol Wireless Mesh Networks 

    Abdalla, Taha; Rey-Moreno, Carlos; Tucker, William David; Bagula, Antoine (Telkom, 2015)
    Wireless Mesh Networks (WMNs) have emerged as an alternative option to the wired networks in areas where wired deployment is unfeasible and/or costly. They have been widely adopted in community networks as these networks ...
  • Untitled 

    Tucker, William David; Westerveld, Rudi (John Wiley & Sons, 2015)
    Local access in the context of regions in the global South continues to undergo transformation due to the growing ubiquity of mobile connectivity and the recent appearance of what have been termed “inverse” telecommunication ...
  • Usability of an authoring tool for generalised scenario creation for signsupport 

    Duma, Lindokuhle; Chininthorn, Prangnat; Glaser, Meryl; Tucker, William David (Telkom, 2015)
    This paper presents the usability testing results for an authoring tool that generalises scenario creation for a tool called SignSupport. SignSupport is a mobile communication tool for Deaf people that currently runs ...
  • Local ownership, exercise of ownership and moving from passive to active entitlement: a practice-led inquiry on a rural community network 

    Rey-Moreno, Carlos; Sabiescu, Amalia; Siya, Masbulele Jay; Tucker, William David (CCIRDT, 2015)
    In this paper, we aim to shed light on local ownership from a double practical and theoretical perspective, and examine its meaning as well as the factors that are bound to influence its development in community based ...
  • A participatory design for a billing system: A South African case study of a community based telephony system 

    Ufitamahoro, Marie Josee; Venter, Isabella; Rey-Moreno, Carlos; Tucker, William David (ACM, 2014)
    This paper describes the role participatory design can play in developing and implementing an information and communication technology for development project in a rural area. It shows how the process of co-designing an ...
  • Rural Wireless Mesh Network Analysis on Mobile Devices 

    Tiemeni, Ghislaine Livie Ngangom; Venter, Isabella; Tucker, William David (Telkom SA, 2014)
    The aim of this research effort is to build an efficient and accurate mobile traffic generator based on open source computer-based traffic generator software. A high performance mobile traffic generator would make the ...
  • An analysis of voice over Internet Protocol in wireless mesh networks 

    Meeran, Mohammed Tariq; Tucker, William David (IEEE, 2014)
    The paper focuses on analyzing the affects of wireless mesh networks with some mobile nodes on Voice over Internet Protocol service quality. Our interest is to examine this in simulation to learn how to better deploy voice ...
