Thesis (MTech (Business Administration in Project Management))--Cape Peninsula University of Technology, 2017. / The beginning of the 2011 academic year in South Africa saw a number of Institutions of Higher Learning introducing online registration for their students. The efficiency and effectiveness of Information Systems is increasingly becoming a necessity and not an option for many organizations. An information system should be able to allow end users to access information easily and navigate with ease. The selected University of Technology (UoT) in this research is one of the largest public institution of higher learning in the Western Cape Province and boasts of an enrolment of more than 30 000 students per academic year. An observation was made that, during registration students stand in long queues waiting to register or for assistance to register. The system tends to ‘freeze’ whilst students are registering and students are in most cases unfamiliar with the system interface. They constantly have to enquire what to do next when going through online registration process. This study adopted a quantitative approach. The study uses constructs of the updated DeLone and McLean IS success model (2003) to analyse and explain the student’s perceptions of the online registration system. The research was undertaken to establish the student’s perceptions of the online registration system. This research identifies the challenges and success factors of introducing an online registration system, from a students’ perspective, whilst highlighting the extent to which this system has been able to solve problems associated with the manual registration era. The study seeks to assist management and those responsible for managing the current system to determine how well the system is working or not working to achieve user satisfaction. It will also assist them going forward on what to consider before, during and after implementation of an information system. Stemming from the findings of this study, recommendations were made such as making online registration available on mobile devices, online registration orientation can assist students navigate the system easily. The UoT should also consider thorough training for staff that assist students during registration to ensure good service quality.

Motor impaired people are faced with many challenges, one being the of lack integration into certain spheres of society. Access to information is seen as a major issue for the motor impaired since most forms of interaction or interactive devices are not suited to the needs of motor impaired people. People with motor impairments, like the rest of the population, are increasingly using mobile phones. As a result of the current devices and methods used for interaction with content on mobile phones, various factors prohibit a pleasant experience for users with motor impairments. To counter these factors, this study recognizes the need to implement better suited methods of interaction and navigation to improve accessibility, usability and user experience for motor impaired users. The objective of the study was to gain an understanding of the nature of motor impairments and the challenges that this group of people face when using mobile phones. Once this was determined, a solution to address this problem was found in the form of natural user interfaces. In order to gain a better understanding of this technology, various forms of NUIs and the benefits thereof were studied by the researcher in order to determine how this technology can be implemented to meet the needs of motor impaired people. To test theory, the Samsung Galaxy s5 was selected as the NUI device for the study. It must be noted that this study started in the year 2013 and the Galaxy S5 was the latest device claiming to improve interaction for disabled people at the time. This device was used in a case study that made use of various data collection methods, including participant interviews. Various motor impaired participants were requested to perform predefined tasks on the device, along with the completion of a set of user experience questionnaires. Based on the results of the study, it was found that interaction with mobile phones is an issue for people with motor impairments and that alternative methods of interaction need to be implemented. These results contributed to the final output of this study, namely a set of user experience guidelines for the design of mobile human computer interaction for motor impaired users.

Thesis (MTech(Information Technology))--Cape Technikon, Cape Town, 1997 / This research discusses some of the cultural issues that could influence the human computer encounter in a multicultural community. The results of research to determine differences in computer usage caused by cultural differences when using computer user interfaces in simulated and real-world environments are also discussed. Various cultural aspects could possibly influence the effectiveness of the user interface in a multicultural society. Language is an important factor and studies have shown that simple translation will increase productivity (Bodley, 1993:23). However all languages do not contain the necessary technical vocabulary. Mothers from a lower social class typically use a limited language code when communicating with their children (Mussen et aI.,1984:206). As this causes the children to think in more concrete and less conceptual terms, it may influence the human computer interaction, particularly where a high degree of abstraction, such as in graphical interfaces, is used. Symbolism is problematic as symbols like light bulbs, recycle bins and VCR controls do not feature in the life of users living in slum and backward rural conditions. Lack of exposure to technology might negatively influence user attitude (Downton, 1991:25) with a corresponding inhibition of learning and performance. All external locus of control is common among disadvantaged groups due to the high degree of rejection, hostile control and criticism they experience. As the sense of being out of control is largely associated with the indication to avoid stressful situations, users from these groups might prefer to avoid situations where they do not feel in control. The strong differentiation between the roles of the sexes in certain cultures can also influence the encounter with the computer (Downton, 1991:10) It has been shown that the different gender orientations towards problem solving in these cultures can have an important influence on computer usage. The intracultural factors of social class play a significant role in determining how a person acts and thinks (Baruth & Manning, 1991 :9-1 0). Such differences may sometimes be more pronounced than those resulting from cultural diversity and may influence the orientation of the user towards abstraction and generalization.

É apresentada uma comparação entre diversas linguagens declarativas relacionadas à especificação de interfaces de usuário, todas baseadas em XML. É feita então uma proposta de uso da linguagem XForms, conjuntamente com CSS, na definição de interfaces de usuário destes dispositivos, como alternativa à solução vigente. Como meio de validar a proposta, é definido um modelo para a interface de usuário, tendo como base um telefone celular existente no mercado. Em seguida é descrito como XForms e CSS podem ser utilizados na especificação da interface de usuário dos dispositivos correspondentes a este modelo. São incluídas uma proposta de arquitetura e as extensões necessárias à linguagem XForms. Este trabalho demonstra a necessidade de um número reduzido de extensões para que XForms e CSS possam ser utilizados com este propósito. / Abstract: This work describes several problems related to user interface development that currently affect the industry of portable devices. We present a brief comparison between existing declarative languages based on XML related to user interface specification. We propose the use of XForms and CSS as an alternative to the current approach. In order to validate the proposal, a model for the user interface is presented, based on existing cellular phones on the market. We show how XForms and CSS could be used as user interface definition languages for the portable devices based on that model. It is included an architecture proposal and the required extensions to the W3C XForms recommendations. We conclude the feasibility of this proposal based on the small number of extensions required for that. / Mestrado / Engenharia de Computação / Mestre em Ciência da Computação

Esta necessidade impulsionou, no último século, o desenvolvimento de dispositivos robóticos, que foram se tornando cada vez mais complexos, à medida que a tecnologia avançava. No entanto, quanto mais complexos, mais difícil se torna sua operação. Reduzir a complexidade de operação destes dispositivos sem comprometer sua eficácia é um objetivo desejável e que tem impulsionado significativos esforços de pesquisa ultimamente. Neste trabalho, estudam-se duas tecnologias diferentes que podem ser aplicadas de forma complementar para tornar a operação de dispositivos robóticos mais simplificada. A área de Interfaces Naturais estuda a criação de mecanismos de operação baseados nas formas naturais de interação entre os seres humanos e os computadores, como gestos e fala, visando diminuir a curva de aprendizado para a operação de sistemas complexos, tornando esta uma tarefa intuitiva. A Realidade Aumentada tem entre seus objetivos ampliar o conhecimento sobre uma certa situação ao apresentar a um usuário informações adicionais fornecidas por instrumentação. Para isso, faz uso de técnicas de Computação Gráfica. Também permite criar situações simuladas para avaliar o comportamento de sistemas, ou treinamento para a operação destes sistemas de maneira virtual. Neste trabalho, montou-se um experimento em que um braço robótico será acionado de forma natural, através de gestos do usuário, em um ambiente de Realidade Aumentada. Como transdutor para a captura do movimento do usuário, foi o usado o sensor Kinect¿, que é um equipamento disponível comercialmente com custo relativamente baixo. Foi desenvolvida uma arquitetura que permite o acionamento da plataforma robótica de forma remota, através de comunicação em rede / Abstract: Since the beginning of History and particularly of the Industrial Revolution, human beings have sought to replace or supplement their workforce with devices and machines, in order to expand their productive capacity or to solve tasks for which the use of human power is not satisfactory or it is dangerous. This need pushed the development of robotic devices in the last century, which have become increasingly complex as technology advances. However, the more complex it is, more difficult its operation becomes. Reducing these devices operational complexity without compromising its effectiveness is a desirable goal that has driven significant research efforts lately. In this work, two different technologies are studied which can be applied in a complementary way to simplify robotic operation. The area of Natural Interfaces studies the creation of software mechanisms, based on natural forms of interaction between humans and computers, such as gestures and speech, in order to reduce the learning curve for the operation of complex systems, making it more intuitive. Augmented Reality has among its objectives to expand the knowledge about certain situations, presenting to the user additional instrumentation provided information. To accomplish this objective, Augmented Reality makes use of Computer Graphics techniques. It also allows the creation of simulated scenarios to evaluate the behavior of systems, or for virtually training the operators of these systems. In this work, an experiment was set up in which a robotic arm is activated through user gestures in an Augmented Reality environment. As a low cost commercially available equipment, the Kinect¿ sensor is adopted to capture the user's movement. An architecture was developed and tested with auspicious results, implementing the proposed natural interface to interpret the human gestures and to provoke the respective remote activation of the robotic platform through network communication / Mestrado / Mecanica dos Sólidos e Projeto Mecanico / Mestre em Engenharia Mecânica

La communauté du génie logiciel porte depuis ses débuts une attention spéciale à la qualité et la fiabilité des logiciels. De nombreuses techniques de test logiciel ont été développées pour caractériser et détecter des erreurs dans les logiciels. Les modèles de fautes identifient et caractérisent les erreurs pouvant affecter les différentes parties d’un logiciel. D’autre part, les critères de qualité logiciel et leurs mesures permettent d’évaluer la qualité du code logiciel et de détecter en amont du code potentiellement sujet à erreur. Les techniques d’analyses statiques et dynamiques scrutent, respectivement, le logiciel à l’arrêt et à l’exécution pour trouver des erreurs ou réaliser des mesures de qualité. Dans cette thèse, nous prônons le fait que la même attention doit être portée sur la qualité et la fiabilité des interfaces utilisateurs (ou interface homme-machine, IHM), au sens génie logiciel du terme. Cette thèse propose donc deux contributions dans le domaine du test et de la maintenance d’interfaces utilisateur : 1. Classification et mutation des erreurs d’interfaces utilisateur. 2. Qualité du code des interfaces utilisateur. Nous proposons tout d’abord un modèle de fautes d’IHM. Ce modèle a été conçu à partir des concepts standards d’IHM pour identifier et classer les fautes d’IHM ; Au travers d’une étude empirique menée sur du code Java existant, nous avons montré l’existence d’une mauvaise pratique récurrente dans le développement du contrôleur d’IHM, objet qui transforme les évènements produits par l’interface utilisateur pour les transformer en actions. Nous caractérisons cette nouvelle mauvaise pratique que nous avons appelée Blob listener, en référence à la méthode Blob. Nous proposons également une analyse statique permettant d’identifier automatiquement la présence du Blob listener dans le code d’interface Java Swing. / The software engineering community takes special attention to the quality and the reliability of software systems. Software testing techniques have been developed to find errors in code. Software quality criteria and measurement techniques have also been assessed to detect error-prone code. In this thesis, we argue that the same attention has to be investigated on the quality and reliability of GUIs, from a software engineering point of view. We specifically make two contributions on this topic. First, GUIs can be affected by errors stemming from development mistakes. The first contribution of this thesis is a fault model that identifies and classifies GUI faults. We show that GUI faults are diverse and imply different testing techniques to be detected. Second, like any code artifact GUI code should be analyzed statically to detect implementation defects and design smells. As for the second contribution, we focus on design smells that can affect GUIs specifically. We identify and characterize a new type of design smell, called Blob listener. It occurs when a GUI listener, that gathers events to treat and transform as commands, can produce more than one command. We propose a systematic static code analysis procedure that searches for Blob listener that we implement in a tool called InspectorGuidget. Experiments we conducted exhibits positive results regarding the ability of InspectorGuidget in detecting Blob listeners. To counteract the use of Blob listeners, we propose good coding practices regarding the development of GUI listeners.
