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 ... -
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 ... -
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 energy consumption on low-end smartphones
Om, Shree; Tucker, William David; Rey-Moreno, Carlos; Erasmus, Zenville (2015)The relationship between battery consumption in smartphones and the usage statistics of a phone is direct. Modern smartphones, even low-end, are equipped with multiple wireless technologies, e.g. GSM, 3G, WiFi and ... -
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)The DEV community knows that technology interventions involve consideration of social and environmental factors as much as technical ones. This is particularly true for the introduction of communications infrastructure in ... -
Exploration of Deaf people’s health information sources and techniques for information delivery in Cape Town: A qualitative study for the design and development of a mobile health application
Chininthorn, Prangnat; Glaser, Meryl; Tucker, William David; Diehl, Jan Carel (JMIR Publications, 2016)BACKGROUND: Many cultural and linguistic Deaf people in South Africa face disparity when accessing health information because of social and language barriers. The number of certified South African Sign Language interpreters ... -
FHMIPv6-based handover for wireless mesh networks
Chitedze, Zimani; Tucker, William David (Telkom, 2012)This paper shows that mobility management protocols for infrastructure Internet may be used in a wireless mesh network environment. Mesh topology tends to be an unplanned graph and routes change dynamically and in this ... -
Floor control arbitration for a hybrid voice/text web-board
Benjamin, Anita; Tucker, William David (Telkom, 2003)We have built a hybrid voice/text web–board that utilizes floor control for handling resources such as microphone and interface events. The aim of this research is to determine the most appropriate floor control mechanism ... -
A framework and toolkit for the collection and analysis of QoS statistics for voice traffic in Next Generation Networks
Paulse, Tania M.; Tucker, William David (Telkom, 2000)The multi-service, multi-architecture nature of NGNs is so complex that the management of services, in addition to networks, emerges as a research challenge. Despite QoS limitations, VoIP (as opposed to VoATM), dominates ... -
