Improved Hand-Tracking Framework with a Recovery Mechanism
(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 ... -
Improving quality-of-service in cloud/fog computing through efficient resource allocation
(MPDI, 2019)Recently, a massive migration of enterprise applications to the cloud has been recorded in the IT world. One of the challenges of cloud computing is Quality-of-Service management, which includes the adoption of appropriate ... -
Improving usability and correctness of a mobile tool to help a Deaf person with pharmaceutical instruction
(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 ... -
An in-depth study of the ICT ecosystem in a South African rural community: unveiling expenditure and communication patterns
(Routledge, 2016)There is no doubt of the contributions made by mobile phones and mobile network operators in increasing access to communications in rural areas of developing countries. Yet how affordable is this ubiquitous access in such ... -
Information protection in video relay services
(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 ... -
Insights into the use and affordances of social and collaborative applications for student projects
(South African Institute of Computer Scientists and Information Technologists, 2017)The use of social and collaborative computing has the potential of assisting learning and improving the ability to work together as part of a team. Team work is a graduate attribute that students need to acquire before ... -
Instant Messaging on handhelds: affective feedback
(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
(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. ... -
Intelligent transportation related complex systems and sensors
(MPDI, 2021)Building around innovative services related to different modes of transport and traffic management, intelligent transport systems (ITSs) are being widely adopted worldwide to improve the efficiency and safety of the ... -
An Internet paradigm approach to policy-based network management of legacy kit for VoIP services in Next Generation Networks
(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 ... -
Internet protocol-based push to talk
(Telkom, 2010)This paper discusses a way of offering voice instant messaging based on Internet Protocol using Session Initiation Protocol. The purpose of this investigation is to enhance the modern social communication amongst the people ... -
Internet-of-Things in motion: A UAV coalition model for remote sensing in smart cities
(MDPI AG, 2018)Unmanned aerial vehicles (UAVs) or drones are increasingly used in cities to provide service tasks that are too dangerous, expensive or difficult for human beings. Drones are also used in cases where a task can be performed ... -
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 ... -
An Interoperable signaling solution for IP-based Next Generation Networks
(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 ... -
Investigating battery consumption in low- end smartphones: preliminary results
(International Information Management Corporation, 2017)Due to lack of electricity in the rural communities of Africa, users often have to incur extra expense on recharging their mobile phones. The limited battery capacities of low-end smartphones, therefore, present a barrier ... -
