  • Affective gesture feedback Instant Messaging on handhelds 

    Adesemowo, A. Kayode; Tucker, William David (Institute of Electrical and Electronics Engineers, Inc., 2004)
    Mobile devices and mobile networks are becoming more data-centric (evident in Japanese I-mode) even as mobile network voice Average Revenue Per User are declining, new stream of data services are required which must take ...
  • Connecting bridges across the digital divide 

    Tucker, William David (ACM, 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 ...
  • Handheld fast-track feedback instant messaging 

    Adesemowo, A. Kayode; Tucker, William David (Telkom, 2003)
    As mobile devices and networks become more data-centric, text messaging requires an extension of co-presence capabilities for better interactive discussion between input/output handicapped handheld users and their free ...
  • Instant Messaging on handhelds: affective feedback 

    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): ...
  • Instant messaging on handhelds: an affective gesture approach 

    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. ...
  • Kiara: an open source SIP system to support Deaf telephony 

    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 ...
  • Reliable communication across ad hoc networks 

    Daniels, Francois; Tucker, William David (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 ...
  • A Softbridge with carrier grade reliability using JAIN SLEE 

    Sun, Tao; Tucker, William David (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 ...
  • SoftBridge: a multimodal instant messaging bridging system 

    Lewis, John; Tucker, William David; 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 ...
  • SoftBridge: an architecture for building IP-based bridges over the digital divide 

    Lewis, John; Tucker, William David; 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 ...
  • Web-based telephony bridges for the deaf 

    Glaser, Meryl; Tucker, William David (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. ...
