- Description: This project investigated how to develop a mobile intervention to support medication compliance for patients with chronic and acute diseases. Chronic diseases cannot be cured but can be controlled, usually by taking medication every-day. Therefore, it is very crucial for a patient with a chronic disease to take their medication on time to prevent complications or negative impact on their health. Due to the widespread use of mobile phones, having an automated mobile mechanism to remind patients to take medication is regarded as an effective way of supporting medication compliance. The focus of the research was on investigating how mobile health applications can be used to support patients with chronic and acute diseases in South Africa. Literature identified that medication compliance is low and that a need exists for an intervention to increase compliance. The main goal of this research was to produce a mobile health application to assist medication compliance and support patients with chronic and acute diseases in South Africa and investigate its perceived usefulness. The project made use of two field studies to substantiate its results. The first field study involved patients with chronic diseases and the second one involved patients with acute diseases. The feedback from the first field study and from a literature review was used to redesign the mobile application. The project also investigated the attitude of patients taking medication over a short period of time as well as how such patients compared with those taking chronic medication. The project identified the benefits and disadvantages of using an m-health application to support medication compliance based on the participants’ feedback and behaviour observed in using the application.

- Description: Today's mobile computing devices provide a convenient means to search for points-of-interest (POIs) such as restaurants and accommodation. Mobile Preference-Based Search Tools (PBSTs) allow users to identify POIs such as restaurants or accommodation most suited to their needs and constraints using a mobile device. These devices however, have several design constraints including limited screen space and hardware capabilities. Adaptive User Interfaces (AUIs) have been proposed to address these issues but have not been extensively applied to mobile PBSTs such as mobile tourist guides. In addition, AUIs possess several benefits and advantages over static (traditional) interfaces, which do not take a user's preferences, skill set and experience into account. Little research, however, has been conducted into identifying the potential benefits of AUIs for mobile preference-based searching (PBS). The aim of this research was to determine the extent to which an AUI could improve the effectiveness and user satisfaction of mobile PBS. A literature study was conducted to determine the benefits and limitations of existing mobile PBSTs and determine how these could be improved. The potential benefits of AUIs for mobile PBSTs and a mobile map-based visualisation system were identified. A suitable model for incorporating an AUI into a mobile PBST was identified. The requirements for a mobile PBST were combined with the potentially adaptable objects of a Mobile Map-based Visualisation (MMV) system to provide adaptation suggestions for POInter, an existing mobile tourist guide. A field study using POInter was conducted in order to measure the extent to which participants agreed with suggestions provided for adapting the information, interaction and visualisation aspects of the system. These results were used to derive adaptation requirements for A-POInter, an adaptive version of POInter. Using a model-based design approach, an AUI was designed and implemented for A-POInter. An extensive field study was then conducted to evaluate the usability of the adaptations provided by A-POInter. The quantitative and qualitative data collected from the evaluations allowed the usability of A-POInter to be determined. The results of the field study showed that the participants were highly satisfied with the usability and the usefulness of the adaptations provided by A-POInter. Conclusions and recommendations for future work based on the results of the research were then outlined to conclude the dissertation.

- Description: Mobile commerce, due to its inherent characteristics of mobility and reachability in enhancing personalized services provides an excellent means for life insurers to exploit such avenue in their service offerings. The objective of this study was to determine whether mobile commerce can be used to improve the services of life insurance post-sale activities. This objective was achieved with the relevant literature and empirical study. To accomplish the objective of this treatise, a triangulated research approach was selected and a multiple-case study consisting of four cases was conducted. The four cases selected comprised of leading insurers with large market share in the life insurance market in South-Africa. The primary data were collected through questionnaire and face-to-face interviews with selected respondents. The main finding shows that the respondents had a positive view about mobile commerce and its application in their companies. This was demonstrated by 80 percent of respondents who agreed that mobile commerce was more of an opportunity rather than a challenge or even a threat for the life insurance market. The results also indicate that customer relationship management, mobile messaging services and field service automation functions were used by all the insurers; although minor discrepancies were observed due to the efficiency of each firms IT infrastructure. The Internet was found to assist in the collection of more precise data, to increase service performing abilities. Some of the major obstacles that were found to hinder the deployment of mobile commerce in the industry were security concerns, low and infrequent internet usage and performance by supporting industries. Cumbersome and inefficient legacy systems were declared as the greatest technological weakness particularly by respondents from case 1 and 2. Conversely, hardware and network infrastructure, lack of software packages, lack of technical expertise and the fear of disintermediation was rated low in hindering the deployment of mobile commerce. However, according to the findings the key benefits derived from engaging in increased mobile commerce activities include enhancing customer contact and service, more transparency and speed of claims management, increasing client retention and policy extension rates hence increasing overall company profit.
