- Description: Second economy people in developing countries are people living in communities that are underserved in terms of basic amenities and social services. Due to literacy challenges and user accessibility problems in rural communities, it is often difficult to design user interfaces that conform to the capabilities and cultural experiences of low-literacy rural community users. Rural community users are technologically illiterate and lack the knowledge of the potential of information and communication technologies. In order to embrace new technology, users will need to perceive the user interface and application as useful and easy to interact with. This requires proper understanding of the users and their socio-cultural environment. This will enable the interfaces and interactions to conform to their behaviours, motivations as well as cultural experiences and preferences and thus enhance usability and user experience. Mobile phones have the potential to increase access to information and provide a platform for economic development in rural communities. Rural communities have economic potential in terms of agriculture and micro-enterprises. Information technology can be used to enhance socio-economic activities and improve rural livelihood. We conducted a study to design user interfaces for a mobile commerce application for micro-entrepreneurs in a rural community in South Africa. The aim of the study was to design mobile interfaces and interaction techniques that are easy to use and meet the cultural preferences and experiences of users who have little to no previous experience of mobile commerce technology. And also to explore the potentials of information technologies rural community users, and bring mobile added value services to rural micro-entrepreneurs. We applied a user-centred design approach in Dwesa community and used qualitative and quantitative research methods to collect data for the design of the user interfaces (graphic user interface and voice user interface) and mobile commerce application. We identified and used several interface elements to design and finally evaluate the graphical user interface. The statistics analysis of the evaluation results show that the users in the community have positive perception of the usefulness of the application, the ease of use and intention to use the application. Community users with no prior experience with this technology were able to learn and understand the interface, recorded minimum errors and a high level of v precision during task performance when they interacted with the shop-owner graphic user interface. The voice user interface designed in this study consists of two flavours (dual tone multi-frequency input and voice input) for rural users. The evaluation results show that community users recorded higher tasks successes and minimum errors with the dual tone multi-frequency input interface than the voice only input interface. Also, a higher percentage of users prefer the dual tone multi-frequency input interface. The t-Test statistical analysis performed on the tasks completion times and error rate show that there was significant statistical difference between the dual tone multi-frequency input interface and the voice input interface. The interfaces were easy to learn, understand and use. Properly designed user interfaces that meet the experience and capabilities of low-literacy users in rural areas will improve usability and users‟ experiences. Adaptation of interfaces to users‟ culture and preferences will enhance information services accessibility among different user groups in different regions. This will promote technology acceptance in rural communities for socio-economic benefits. The user interfaces presented in this study can be adapted to different cultures to provide similar services for marginalised communities in developing countries

Cultural and linguistic localization of the virtual shop owner interfaces of e commerce platforms for rural development

- Description: The introduction of Information and Communication Technologies (ICTs) for rural development in rural marginalized societies is vastly growing. However, the success of developing and deploying ICT related services is still in question as influential factors such as adaptability, scalability, sustainability, and usability have great effect on the rate of growth of ICTs in rural environments. The problem is that these ICT services should be maintained and sustained by the targeted communities. The main cause for rural marginalization is the fact that some communities situated in rural settings are educationally challenged and computer illiterate or semiliterate in comparison with urban communities. An ICT for development (ICT4D) intervention in the form of an e-Commerce platform that targets the social and economic growth of rural marginalized communities has been developed and field tested at Dwesa, a rural community located on the Wild Coast of the former homeland of Transkei in the Eastern Cape Province. The e-Commerce platform is known as “buy at Dwesa” and can be visited at this URL, http://www.dwesa.com. The aim of the e-Commerce platform is to motivate small entrepreneurs in rural areas to market their products and themselves to the global market as they lack the skills and resources for marketing their art and crafts. Virtual stores are created for a small group of entrepreneurs who will maintain and sustain the stores on their own. These entrepreneurs are often elderly women with limited education and little to no computer literacy - meaning that sustaining the stores may prove difficult for them. In this research we discuss the re-design and re-development of the virtual shop-owner interfaces of the e-Commerce platform to make them more culturally and linguistically localized. The virtual shops allow shop-owners to upload their artifacts to advertise and sell on the customer’s end of the e-Commerce platform. For multilingual and multicultural communities, adoption of the software interfaces to the user’s cultural and linguistic needs and modes of expression is important as failure to do so may reduce the level of benefits of e-Commerce initiatives.

- Description: In the recent past, wireless sensor technology has undergone advancements in its autonomous data collecting aspects, and has become an area worth investigating in relation to structural monitoring applications. The system described in this thesis aims at acquiring, storing and displaying overhead transmission line related data collected from a wireless sensor network. Open source tools were used in its development and implementation. The inherent linearly aligned topology of transmission line monitoring devices is not without shortcomings; hence analysis of linear node placement, hardware and software components was carried out to determine the feasibility of the system. Their limited data processing capabilities has motivated the development of a post processing wireless sensor application in order to present any collected structural data in an understandable format.
