  • Lewis, John; Tucker, William D.; 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 ...
  • Lewis, John; Tucker, William D.; 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 ...
  • Tucker, William D.; Glaser, Meryl; Lewis, John (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 ...
  • Sun, Tao; Tucker, William D. (Telkom, 2004)
    We have built a SoftBridge prototype within a JAIN (Java APIs for the Integrated Network) SLEE (Service Logic Execution Environment). A SoftBridge is a semi-synchronous multimodal IP (Internet Protocol) -based communication ...
  • Agbele, Kehinde K.; Adesina, Ademola Olusola; Ekong, Daniel; Ayangekun, Oluwafemi (Hindawi Publishing Corporation, 2012)
    People use search engines to find information they desire with the aim that their information needs will be met. Information retrieval (IR) is a field that is concerned primarily with the searching and retrieving of ...
  • Ghaziasgar, Mehrdad; Connan, James (2008)
    Current wireless human-computer interaction devices such as wireless mice and touchscreens, by and large, incorporate a sophisticated electronic architecture. The sophistication achieves wireless capabilities but carries ...
  • Glaser, Meryl; Tucker, William D. (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. ...
  • Chetty, Marshini; Tucker, William D.; 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 ...
  • Penton, Jason; Tucker, William D.; Glaser, Meryl (Telkom, 2002)
    We have developed a prototype bridge that relays text and speech between Teldem, a text telephone for the Deaf, and a standard telephone or H.323 endpoint. Telgo323 uses modified H.323 media gateways and open source Text ...
  • Adesina, Ademola Olusola; Agbele, Kehinde K.; Nyongesa, Henry O. (Telkom, 2010)
    HIV/AIDS continues to be a menace to the global community, especially in sub-Saharan Africa and South Africa is not an exception. The infection rate is continues to grow, in particular, among the young adults. Cell ...
  • Azeez, Nureni A.; Abidoye, Ademola P.; Adesina, Ademola Olusola; Agbele, Kehinde K.; Oyewole, A.S. (Akamai University, 2012)
    The rapid advancement in Information and Communication Technology (ICT) has undoubtedly influenced positive changes in carrying out administrative functions in government institutions. The ICT adoption rate in Africa is ...
  • Rey-Moreno, Carlos; Roro, Zukile; Siya, Masbulele Jay; Simo-Reigadas, Javier; Bidwell, Nicola J.; Tucker, William D. (Telkom, 2012)
    This paper presents the work done thus far towards designing a sustainable business model for rural telephony in the community of Mankosi, located in the Eastern Cape province of South Africa. The pillars of the model are ...
  • Azeez, Nureni A.; Venter, Isabella M. (South African Institute of Electrical Engineers, 2013)
    The application of grid computing has been hampered by three basic challenges: scalability, interoperability and efficient access control which need to be optimized before a full-scale adoption of grid computing can take ...
  • Rey-Moreno, Carlos; Tucker, William D.; Simo-Reigadas, Javier (ACM, 2013)
    Little is known about how mid-range, or several km, dis- tances a ect multipoint-to-multipoint links when single ra- dio nodes with omnidirectional antennas are used. In this poster, a real network with these characteristics ...
  • Abidoye, Ademola P.; Azeez, Nureni A.; Adesina, Ademola Olusola; Agbele, Kehinde K. (Academic Journals Inc., 2011)
    Transceivers are the major energy consumption in a Wireless Sensor Network which is made of low-power, small in size, low cost and multi-functional nodes. These sensor nodes are operated by batteries which put significant ...
  • Ufitamahoro, Marie Josée; Venter, Isabella M.; Tucker, William D.; Rey-Moreno, Carlos (ACM, 2013)
    The principal objective of this paper is to describe the au- thor's eldwork and research in a remote rural area of South Africa, where a Village Telco is deployed to provide Voice over Internet Protocol on a wireless mesh ...
  • Blake, Edwin H.; Tucker, William D. (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 ...
  • Chetty, Marshini; Tucker, William D.; 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 ...
  • Abidoye, Ademola P.; Azeez, Nureni A.; Adesina, Ademola Olusola; Agbele, Kehinde K. (Scientific Research Publishing, 2011)
    Recent technological advances in wireless communications and wireless sensor networks have enabled the design of low-cost, intelligent, tiny, and lightweight medical sensor nodes that can be strategically placed on human ...
  • Glaser, Meryl; Tucker, William D. (Telkom, 2001)
    A Teldem provides text-based telephony services to the deaf. Despite an array of text-based communications mechanisms on the web, the Teldem is the only means of synchronous telecommunication available to a deaf person. ...
