SoftBridge: a multimodal instant messaging bridging system
(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 ...
Guaranteed delivery of semi-synchronous IP-based communication
(Telkom, 2005)
This paper presents an empirical solution for guaranteeing the delivery of synchronous and asynchronous messages within a semi-synchronous IPbased communication domain. The communication infrastructure that is needed between ...
MUTI Telehealth
(2007)
For four years we have been iteratively evolving MUTI, a rural telehealth system, for hospitals and clinics in a remote rural part of the Eastern Cape in South Africa (Chetty, 2005; Chetty et al., 2003, 2004a; Maunder et ...
Telemedicine using VoIP combined with a store and forward approach
(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 ...
Telgo323: an H.323 Bridge for deaf telephony
(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 ...
An interoperable signaling solution between SIP and H.323
(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 ...
A framework and toolkit for the collection and analysis of QoS statistics for voice traffic in Next Generation Networks
(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 ...
Web-based telephony bridges for the deaf
(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. ...
A surface acoustic wave touchscreen-type device using two transducers
(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 ...
Real-time gesture recognition using eigenvectors
(2009)
This paper discusses an implementation for gesture
recognition using eigenvectors under controlled conditions. This
application of eigenvector recognition is trained on a set of
defined hand images. Training images are ...
