The main goal of this research has been to investigate elderly people's needs, perceptions, fears, hopes, and expectation regarding elderly care, including ethical issues linked to assistive technologies. As faith seems to take an important place in how some elders face the aging process, the spiritual dimension was also included. Therefore, the research was conducted among 15 church congregants. Results show that most respondents fear the physical and mental decay due to aging, often resulting in becoming a burden to someone else, along with abandonment and lack of financial resources. Most ethnic groups perceive that other cultures take better care of their elders than their own. Faith seems to offer a great support, as it gives the confidence that divine power will always be there for them even beyond death. The respondents in this research suggest that guidance should be provided in a more structured way, more focus should go on the youth and the elderly, more activities should be organized and practical information should be shared. Regarding the ethical issues of assistive technologies, they are not well informed about their possibilities but acknowledge their potential usefulness, combined with human care. They don't want technology to be too intrusive in their daily life, but they are willing to sacrifice (part of) their privacy for more (medical) safety. There is a general concern that the access to qualitative care would be depending on financial resources.

While a lot of efforts have been on outdoor intelligent systems, internal living environment system that suits the occupancy’s behaviour has not received much attention. The intelligent living environment designed in this study has three components; the physical world (environment), the database and the decision maker. The study sought to design a model that senses ever changing home conditions such as lights, doors and windows. Other variables that were looked at include, but not limited to the number of people in the room and inside thermodynamics and human activity. Global information such as temperature, gas or electricity usage and time of the day will also be received by the system through various sensing facilities. The information will be sent to a rules engine for a decision on an appropriate action to be taken. The action may include just turning off the lights, in the case of a mild abnormality or a high alert to an emergency response unit in a most severe case. The study proposes a context aware and proactive neural networks control system to control a living environment with a main focus on the aged citizens living alone. The proposed living environment was not developed to an actual or “mock” building containing a representation of subset of sensors, actuators and controllers as used in the actual systems due to lack of funding. However, the study will report on the modelling and simulation of the home system variables based on the chosen Artificial Intelligent technique using MATLAB/SIMULINK. These results indicate a possibility of implementing the designed living environment to increase the resident’s security. / Electrical and Mining Engineering / M. Tech. (Engineering: Electrical)

This dissertation thesis addresses the area of spatial navigation of the blind. The author theoretically deals with a complex interplay of psychological functions involved in spatial navigation with respect to the specific conditions of the blind. The empirical part of the thesis presents an experimental study in the population of the blind (N=44). This study focuses on effects of the stress recovery phase from shortly increased stress levels on the process of learning a new route. The experiment is placed in real-world settings and overcomes some of the methodological flaws typical for this research domain. The research evidence suggests that the recovery phase from shortly increased stress levels hinders the development of procedural knowledge of the route. However, this deterioration in route knowledge is not associated with the effects of the strsss phase itself, but affects only the recovery phase part of the route in which stress levels are returning to their original baseline levels (not necessarily the level of the resting conditions). Besides its theoretical conclusions, the value of the presented thesis is in its contribution to the advancements of research methods in the given field. The outcomes of this work are practically applicable to the development of navigation aids for the blind....

Abstract in English, Tswana and Afrikaans / People who graduated from higher education, whether they attended classes on campus or studied via a distance mode of learning, have not only been educated but are also able to participate in and contribute positively to the political, social and economic forums in their immediate environments and within their country. Progressing through the higher education system successfully is not easy since there are many challenges to overcome. Students With Disabilities (SWD) face even greater challenges in making their way through the system to emerge triumphantly as graduates. Institutions of higher learning, including Open Distance eLearning (ODeL) facilities, must provide support to SWD in order to facilitate their learning experience so that they are better equipped to succeed. Therefore, it is vital to promote access to higher education for people with disabilities and to provide support, such as making assistive technologies and human services available, for SWD within ODeL institutions. This qualitative study was exploratory in nature and used a multiple case study research design in the chosen area to investigate the provision of support for SWD in the ODeL institution. Data were collected by means of semi-structured interviews and a document analysis, and these two methods of data gathering assisted with triangulation. The research findings revealed differences between the findings that were obtained through the responses received from teacher and staff member participants. The research findings also revealed differences between the findings that were obtained through the responses received from the participants, in general, and those obtained through the document analysis. The findings obtained through responses received from teacher participants showed that support for SWD was more evident at the school level than at the ODeL institution, that is, at the tertiary level of education. The document analysis of the policies of the ODeL institution revealed that the policies were general and did not specifically relate to the needs of SWD. At the same time, the findings in this dissertation of limited scope showed that the use of technology and the availability of assistive devices were more prominent at the school level than at the ODeL institution. / Batho ba ba alogang go tswa mo ditheong tse kgolwane tsa Thuto, ba tswa ba ka bo ba rutilwe le go ithuta ka go tsenela dikamuso (attending lecturers) mo khemphaseng kgotsa ba rutilwe le go ithuta ka thutotlhaeletsano, ga ba rutega fela mme ba kgona gape le go nna le seabe le go abelana ka tshiamo mo diforamong tsa sepolotiki, tsa seloago le tsa seikonomi mo ditikologong tse ba iphitlhelang ba le mo go tsona naga ka bophara.

Dit is nie maklik om suksesvol deur die hoëronderwysstelsel te vorder nie, omdat daar baie struikelblokke is om te oorkom. Studente met gestremdhede (SMG) het selfs meer uitdagings om hul weg deur die stelsel te baan en triomfantlik as graduandi te verrys. Hoëronderriginstellings, insluitende oop e-afstandsleer (ODeL) -fasiliteite, moet ondersteuning aan SMG bied om hul leerervarings te fasiliteer sodat hulle beter toegerus is om sukses te behaal. Dit is daarom noodsaaklik om toegang tot hoër onderwys en ondersteuning aan mense met gestremdhede te bied, soos om hulptegnologieë en menslike dienste aan SMG in ODeL-instellings beskikbaar te stel. Hierdie kwalitatiewe studie was verkennend van aard en het 'n veelvoudige gevallestudie-ontwerp in die gekose veld gebruik om die voorsiening van ondersteuning aan SMG in 'n ODeL-instelling te ondersoek. Data is versamel deur semigestruktureerde onderhoude en 'n dokumentonleding; hierdie twee metodes van dataversameling het met triangulasie gehelp. Navorsingsbevindings het verskille aangedui tussen die data wat verkry is van die onderwyser en die van deelnemende personeellede se reaksies. Navorsingsbevindings het ook verskille aangedui tussen die data wat verkry is van deelnemers se reaksies oor die algemeen en die wat deur dokumentontleding verkry is. Die bevindings wat deur die onderwyserdeelnemers verkry is, het aangedui dat ondersteuning aan SMG duideliker op skoolvlak was as by die ODeL-instelling; dit is op tersiêre vlak van onderwys. Die dokumentontleding van die ODeL-instelling se beleide het aangedui dat die beleide algemeen was nie spesifiek met SWD se behoeftes verband hou nie. Terselfdertyd het die bevindings van hierdie verhandeling van beperkte omvang getoon dat die gebruik van tegnologie en die beskikbaarheid van hulptoestelle meer prominent was op skoolvlak as by die ODeL-instelling. / Curriculum and Instructional Studies / M.
