Factors Influencing The Perceptions Of Human-Computer Interaction Curriculum Developers In Higher Education Institutions During Curriculum Design And Delivery, Cynthia Augustine, Salah Kabanda
The African Journal of Information Systems
Computer science (CS) and information systems students seeking to work as software developers upon graduating are often required to create software that has a sound user experience (UX) and meets the needs of its users. This includes addressing unique user, context, and infrastructural requirements. This study sought to identify the factors that influence the perceptions of human-computer interaction (HCI) curriculum developers in higher education institutions (HEIs) in developing economies of Africa when it comes to curriculum design and delivery. A qualitative enquiry was conducted and consisted of fourteen interviews with HCI curriculum developers and UX practitioners in four African countries. …
Factors That Influence The Implementation Of Information And Communication Technology Inclusive Design Practices In Organisations, Faizel Ebrahim, Salah Kabanda, Guidance Mthwazi
Factors That Influence The Implementation Of Information And Communication Technology Inclusive Design Practices In Organisations, Faizel Ebrahim, Salah Kabanda, Guidance Mthwazi
African Conference on Information Systems and Technology
Inclusive design in information and communication technology (ICT) is the development of information and communication technology artifacts that are accessible and easy to use for as many people as possible. Human diversities must be considered when producing these inclusive design artifacts. It is not only important for abled people but also extends to people with disabilities, the elderly and anybody challenged with using these artifacts. Yet, few designers and developers adopt inclusive design methodologies in their practice. This study seeks to identify and understand the factors that influence the implementation of inclusive design practices in organisations. The methodology was based …
The Social Market Economy As A Formula For Peace, Prosperity, And Sustainability, Almuth D. Merkel
The Social Market Economy As A Formula For Peace, Prosperity, And Sustainability, Almuth D. Merkel
Doctor of International Conflict Management Dissertations
The social market economy was developed in Germany during the interwar period amidst political and economic turmoil. With clear demarcation lines differentiating it from socialism and laissez-faire capitalism, the social market economy became a formula for peace and prosperity for post WWII Germany. Since then, the success of the social market economy has inspired many other countries to adopt its principles. Drawing on evidence from economic history and the history of economic thought, this thesis first reviews the evolution of the fundamental principles that form the foundation of social-market economic thought. Blending the micro-economic utility maximization framework with traditional growth …
Graphical Representation Of Text Semantics, Karl Kevin Tiba Fossoh
Graphical Representation Of Text Semantics, Karl Kevin Tiba Fossoh
Master of Science in Computer Science Theses
A text is a set of words conveying a particular semantic based on their order, representation and structure. Those elements can be associated through a different set of interpretations, based on frequency and proportionality. The problem with context is that numbers do not help understand the semantics and fall short to convey the message of the text. The graphical representation of text semantics focuses on the conversion of text to images. Contrarily to word clouds that simply produce frequency mapping of words within the text and topic models that essentially give context to word frequencies and proportionalities, images keep intact …
Virtual Reality As Navigation Tool: Creating Interactive Environments For Individuals With Visual Impairments, Nick Murphy
Virtual Reality As Navigation Tool: Creating Interactive Environments For Individuals With Visual Impairments, Nick Murphy
Master of Science in Computer Science Theses
Research into the creation of assistive technologies is increasingly incorporating the use of virtual reality experiments. One area of application is as an orientation and mobility assistance tool for people with visual impairments. Some of the challenges are developing useful knowledge of the user’s surroundings and effectively conveying that information to the user. This thesis examines the feasibility of using virtual environments conveyed via auditory feedback as part of an autonomous mobility assistance system. Two separate experiments were conducted to study key aspects of a potential system: navigation assistance and map generation. The results of this research include mesh models …
Accessibility And Usability Of Government Websites In Tanzania, Joel S. Mtebe, Aron W. Kondoro
Accessibility And Usability Of Government Websites In Tanzania, Joel S. Mtebe, Aron W. Kondoro
The African Journal of Information Systems
The government of Tanzania has been embracing information systems specifically websites in order to widen access to government services, lower administrative costs, and to increase public participation in decision making. As a result, almost every ministry, department, and agency (MDA) has developed a website of different kind. However, the majority of existing websites were developed without sufficiently considering user needs which indicates that they do have some usability and accessibility problems. This study used SortSite tool to evaluate accessibility and usability of government websites taking a sample of 22 websites. The report from the SortSite tool was then checked against …
Towards Understanding And Developing Virtual Environments To Increase Accessibilities For People With Visual Impairments, Miao Dong
Master of Science in Computer Science Theses
The primary goal of this research is to investigate the possibilities of utilizing audio feedback to support effective Human-Computer Interaction Virtual Environments (VEs) without visual feedback for people with Visual Impairments. Efforts have been made to apply virtual reality (VR) technology for training and educational applications for diverse population groups, such as children and stroke patients. Those applications had already shown effects of increasing motivations, providing safer training environments and more training opportunities. However, they are all based on visual feedback. With the head related transfer functions (HRTFs), it is possible to design and develop considerably safer, but diversified training …

The computer game industry has exploded reaching sales of several billion dollars a year and, consequently, a majority of college students are familiar with the gaming environment. In fact, videogame development has been cited as one way to motivate students to explore the world of Computer Science. However, most videogames are extremely complex computer programs created by a team of developers including programmers and graphic artists and represent thousands of hours of work. Fortunately there are software tools available that provide a way for simple computer games to be created fairly easily using a building block approach. This paper discusses …
