  • Designing mobile phone interfaces for age diversity in South Africa: “One-World” versus diverse “Islands” 

    Renaud, Karen; Blignaut, Renette; Venter, Isabella M. (Springer, 2013)
    Designing for diversity is a laudable aim. How to achieve this, in the context of mobile phone usage by South African seniors, is a moot point. We considered this question from two possible perspectives: universal ...
  • 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)

  • 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 ...
  • Digital watermarking: a state-of-the-art review 

    Adesina, Ademola Olusola; Nyongesa, Henry O.; Agbele, Kehinde K. (IIMC International Information Management Corporation, 2010)
    Digital watermarking is the art of embedding data, called a watermark, into a multimedia object such that the watermark can be detected or extracted later without impairing the object. Concealment of secret messages inside ...
  • Empowerment of rural farmers through information sharing using inexpensive technologies 

    Iraba, M. Louise; Venter, Isabella M. (ACM, 2011)
    This paper discusses how to empower rural farmers to do business by means of inexpensive mobile technologies. In particular, the aim is to take advantage of the inexpensive features of low-end mobile phones to access market ...
  • Engaging ICTs as a “Tool” for eHealth prioritization on human development and poverty reduction in the African region 

    Agbele, Kehinde K.; Adesina, Ademola Olusola; Ekong, Daniel; Seluwa, Dele (Institute of Electrical and Electronics Engineers (IEEE) Inc., 2011)
    The association connecting information and communication technologies (ICTs) and well-being or poverty remains vague and research today has resulted to divergent conclusions. This paper defines ICTs as “tools” that facilitate ...
  • Ensuring the security and privacy of information in mobile health-care communication systems 

    Adesina, Ademola Olusola; Agbele, Kehinde K.; Februarie, Ronald; Abidoye, Ademola P.; Nyongesa, Henry O. (Academy of Science of South Africa, 2011)
    The sensitivity of health-care information and its accessibility via the Internet and mobile technology systems is a cause for concern in these modern times. The privacy, integrity and confidentiality of a patient’s data ...
  • Ethics and mono-disciplinarity: positivism, informed consent and informed participation 

    Hersh, Marion A.; Tucker, William David (Elsevier, 2005)
    There are a number of pressures on researchers in academia and industry to behave unethically or compromise their ethical standards, for instance in order to obtain funding or publish frequently. In this paper a case study ...
  • Evaluating SMS parsing using automated testing software 

    Adesina, Ademola Olusola; Agbele, Kehinde K.; Abidoye, Ademola P.; Azeez, Nureni A. (Institute of Electrical and Electronics Engineers (IEEE) Inc., 2012)
    Mobile phones are ubiquitous with millions of users acquiring them every day for personal, business and social usage or communication. Its enormous pervasiveness has created a great advantage for its use as a technological ...
  • Evaluating the relevance of the “Real Access” criteria as a framework for rural HCI research 

    Maunder, Andrew; Marsden, Gary; Tucker, William David (ACM, 2006)
    Developing ICT software that is useful and usable in a rural context poses many problems. One of the major difficulties is understanding the real needs of the target users and the constraints imposed by the rural environment. ...
  • Experiences, challenges and lessons from rolling out a rural WiFi mesh network 

    Rey-Moreno, Carlos; Tucker, William David; Bidwell, Nicola J.; Roro, Zukile; Siya, Masbulele Jay; Simo-Reigadas, Javier (ACM, 2013)
