Usability of an authoring tool for generalised scenario creation for signsupport
(Telkom, 2015)This paper presents the usability testing results for an authoring tool that generalises scenario creation for a tool called SignSupport. SignSupport is a mobile communication tool for Deaf people that currently runs ... -
Local ownership, exercise of ownership and moving from passive to active entitlement: a practice-led inquiry on a rural community network
(CCIRDT, 2015)In this paper, we aim to shed light on local ownership from a double practical and theoretical perspective, and examine its meaning as well as the factors that are bound to influence its development in community based ... -
A participatory design for a billing system: A South African case study of a community based telephony system
(ACM, 2014)This paper describes the role participatory design can play in developing and implementing an information and communication technology for development project in a rural area. It shows how the process of co-designing an ... -
Rural Wireless Mesh Network Analysis on Mobile Devices
(Telkom SA, 2014)The aim of this research effort is to build an efficient and accurate mobile traffic generator based on open source computer-based traffic generator software. A high performance mobile traffic generator would make the ... -
An analysis of voice over Internet Protocol in wireless mesh networks
(IEEE, 2014)The paper focuses on analyzing the affects of wireless mesh networks with some mobile nodes on Voice over Internet Protocol service quality. Our interest is to examine this in simulation to learn how to better deploy voice ... -
Co-designing a billing system for voice services in rural South Africa: Lessons learned
(ACM, 2014)Access to information and communication technologies re- mains una ordable for many in rural areas despite recent progress in providing voice services to remote communities. The sustainability of alternative technical ... -
Towards communication and information access for deaf people
(SAICSIT, 2014)In tightly circumscribed communication situations, an interactive system resident on a mobile device can assist Deaf people with their communication and information needs. The Deaf users considered here use South African ... -
Optimisation of SlotTime for a single-radio Mid-Range Multi-hop Wireless Mesh Network
(Telkom SA, 2014)This paper presents the business context and results of an optimisation exercise for a single-radio mid-range multi-hop wireless mesh network for the provision of VoIP services. This WiFi mesh network physically covers 30 ... -
Abstractions for designing and evaluating communication bridges for people in developing regions
(ACM, 2010)This paper describes two novel abstractions that help soft- ware engineers work in developing regions to align social and technical factors when building communication systems. The abstractions extend two concepts familiar ... -
Performance Evaluation of a Wireless Network using a VoIP Traffic Generator on a Mobile Device
(ACM, 2014)The problem of generating different patterns of traffic to emulate real user behaviour is receiving considerable attention with the construction of new and more complex network architectures. The theoretical modelling of ... -
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 ... -
Empowerment of rural farmers through information sharing using inexpensive technologies
(ACM, 2011)This paper discusses how to empower rural farmers to do business by means of inexpensive mobile technologies. In particular, the aim is to take advantage of the inexpensive features of low-end mobile phones to access market ... -
Comparative study of admissions criteria of a selection of South African universities
(Stellenbosch University, 2011)Summary: The new school-leaving certificate, the National Senior Certificate (NSC), was awarded for the first time in 2008. This necessitated a relook at the entrance requirements for university, as the school subjects ... -
Strategies for information management in education: some international experience
(AOSIS Open Journals, 2013)Background: Recent analysis of the management of information and communications technologies in South African education suggests strongly that there is only limited strategic thinking that might guide policy-makers, school ... -
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 ... -
SignSupport: a limited communication domain mobile aid for a Deaf patient at the pharmacy
(Telkom, 2013)This paper discusses a prototype for a communication aid on a mobile phone to support a Deaf1 person visiting a public hospital pharmacy. The aim is to prevent problems of non-compliance to treatment due to poor communication ... -
A mobile platform traffic generator for network performance evaluation
(Telkom, 2013)This work in progress paper presents an overview of the development of an efficient and accurate mobile traffic generator based on an open source computer-based traffic generator software. A high performance mobile traffic ... -
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 ... -
Tuning a mid-range rural WiFi-based mesh network
(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 ... -
Unmasking community trust issues in rural field work
(ACM, 2013)The principal objective of this paper is to describe the au thor's fieldwork 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 ...
