  • Achmed, Imran; Venter, Isabella M.; Eisert, Peter (Telkom, 2013)
    Abstract−Hand-tracking is fundamental to translating sign language to a spoken language. Accurate and reliable sign language translation depends on effective and accurate hand-tracking. This paper proposes an improved ...
  • Motlhabi, Michael B.; Tucker, William David; Parker, Mariam B.; Glaser, Meryl (ACM, 2013)
    The computing for development community knows how to build user interfaces using qualitative methods for text il- literate users, especially on mobile devices. However, lit- tle work has been done speci cally targeting ...
  • Henney, Andre J.; Tucker, William David (ACM, 2013)
    This work in progress paper reports on initial research into the protection of information of the individuals that make use of video relay services. Our research team has developed an application called SignSupport, to aid ...
  • Adesemowo, A. Kayode; Tucker, William David (Telkom, 2004)
    A text only Instant Messaging (IM) built on the IETF open standard SIP/SIMPLE has been developed in line with our proposed introduction of a user-defined text Hotkey feature. These act as an on-click Affective Gesture (AG): ...
  • Adesemowo, A. Kayode; Tucker, William David (SAICSIT in association with ACM, 2005)
    Text communication can be perceived as lacking in chat spontaneity, or plastic, due to medium limitations during interaction. A form of text messaging, Instant Messaging (IM), is now on the uptake, even on mobile handhelds. ...
  • Naidoo, Vaughn; Tucker, William David (Telkom, 2000)
    With QoS available on IP-dominant NGNs, Policy-based Network Management (PBNM) is an effective mechanism for managing services as opposed to actual devices. IP is ubiquitous, and any NGN must contend with legacy devices ...
  • Kobo, Hlabishi Isaac; Tucker, William David; Norman, Michael (Telkom, 2010)

  • Jeffries, Michael; Tucker, William David (Telkom, 2001)
    The Session Initiation Protocol and H.323 dominate the Voice over IP world. These signaling protocols are responsible for call setup and call tear down by IP telephony solutions. This project analyses and discusses the ...
  • Jeffries, Michael; Tucker, William David (Telkom, 2000)
    Current VoIP signaling protocols are interoperable with the PSTN SS7 via H.323-to-SS7 or SIP-to-SS7 gateways. As we move toward the Next Generation Network, the PSTN falls away and we work toward carrier-grade VoIP ...
  • Vuza, Xolisa; Tucker, William David (Telkom, 2004)
    We intend adding video messaging and conferencing to Multimodal Telemedicine Intecommunicator (MuTI), a previous system that has already been in place in the target environment. This is to allow a semi-synchronous communication ...
  • Yi, Long; Connan, James (Association for Computing Machinery, 2007)
    Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ...
  • Yi, Long; Tucker, William David (Telkom, 2008)
    This paper describes Kiara, an open source SIPbased communication system that provides the building blocks to enable Deaf relay services. We have implemented a prototype that provides real-time text, voice and video to a ...
