Ethics and mono-disciplinarity: positivism, informed consent and informed participation
(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 ...
Reliable communication across ad hoc networks
(Telkom, 2008)
This paper presents a fully decentralised peer-topeer voice communication tool intended for use across mobile ad hoc networks (MANET) by distributed groups who desired collaboration. We examined the synergy between MANETs ...
Policy-based network management of legacy equipment in Next Generation Networks
(Telkom, 2001)
Next Generation Networks use policy-based network management and QoS protocols to provide voice services on IP networks. Large numbers of older equipment still push IP packets. We present several solutions that include ...
Adapting x264 to asynchronous video telephony for the Deaf
(Telkom, 2008)
Deaf people want to communicate remotely with sign language. Sign language requires sufficient video quality to be intelligible. Internet-based real-time video tools do not provide that quality. Our approach is to use ...
Asynchronous video telephony for the Deaf
(Telkom, 2007)
The South African Deaf community has very limited telephony options. They prefer to communicate in sign language, a visual medium. Realtime video over Internet Protocol is a promising option, but in reality, the quality ...
Telecommunications bridging between deaf and hearing users in South Africa
(2004)
This paper presents a description of telecommunications for Deaf people in South Africa by contrasting the situation in the developed world. We explain the main motivations for providing a locally appropriate solution. ...
Using voice over IP to bridge the digital divide: a critical action research approach
(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 ...
SoftBridge in action: the first Deaf telephony pilot
(Telkom, 2003)
Following on several partial prototypes, we built an automated Deaf Telephony bridging application with the SoftBridge platform. The SoftBridge performs multi-modal bridging in real-time using Text-to-Speech (TTS) and ...
The role of Outcome Mapping in developing a rural telemedicine system
(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 ...
Bridging communications across the digital divide
(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 ...
