Indigenous Oral traditions should be explored

Two researchers from the University of the Free State (UFS) aim with their research to examine the portrayal of environmental conservation in oral stories from indigenous South African cultures. They also hope to add the under-researched genres of oral cultures to mainstream inter-/cross-/multi-disciplinary inquiries on environmentalism, the climate crisis, conservation and indigenous knowledge systems.  

Dr Oliver Nyambi, Senior Lecturer in the Department of English, and Dr Patricks Voua Otomo, Senior Lecturer in the Department of Zoology and Entomology, interdisciplinary research project titled; Environmentalism in South African oral cultures: an indigenous knowledge system approach, started in 2017. The research is about indigenous South African oral culture as a potential knowledge system in which indigenous forms of environmental awareness is simultaneously circulated and archived.

Understanding oral folk stories

According to Dr Nyambi the research brings together the disciplines of cultural and environmental studies, inquiring into the relationship between indigenous knowledge mediated by oral culture, and environmental awareness. “Our main interest is how we can understand folk oral stories about humanity’s interactions with the environment as creating possibilities for knowing how traditional societies consciously thought about environmental conservation, preserving plant and animal species, and sustaining ecological balance,” says Dr Nyambi

The project has been on hold since 2018 as Dr Nyambi took up a two-and-a-half-year Alexander von Humboldt Fellowship in Germany. It will resume in earnest upon his return to South Africa at the end of February 2021. The duo’s first article on the “Zulu environmental imagination” has since received favorable peer reviews in the reputable journal African Studies Review published by Cambridge University Press.

The aim and impact of the research

Focusing on oral stories from the Zulu, Sotho and Tsonga traditions, the study seeks to understand what, in the stories as well as modes of their transmission, reflects certain consciousness, knowledge and histories of African indigenous environmentalism before the advent of Western forms of conservation. A key dimension to the project is the focus on how indigenous knowledge about the environment and its conservation was/is shared and consequently preserved through storytelling, explains Dr Nyambi.

“We envision our research to spotlight the potential but currently untapped utility of oral cultures in conservation. Our field work in rural KwaZulu-Natal revealed a rich tradition of environmental knowledge, environmental awareness and nature conservation which is mediated and transmitted through folk stories.

“However, traditional modes of storytelling have rapidly declined, mostly due to the pressures of modernity, the often uncritical reverent acceptance of conventional science and its knowledge systems, as well as the dwindling number of human repositories and tellers of indigenous stories. Our research will recommend a systematic approach to the preservation of these stories before they completely disappear,” says Dr Nyambi.

He continues: “Beyond the usual promotion of traditional storytelling as a mechanism of cultural preservation, we will recommend the archiving of the stories in written form, inclusion in school material as part of moral education, and modernisation for easy circulation through, for instance, animation.”

Receiving funding

The researchers successfully applied for funding which they mainly used for field work. The project involves travelling to rural communities where much of the oral stories and storytelling exist. They also use the money to purchase, where applicable, published stories for analysis.

“We wouldn't be able to do this vital study without funding so we feel that the grant is a crucial enabler of this process of seeking and indeed making knowledge of this rarely-talked-about topic with implications for how indigenous knowledge can be harnessed in ongoing attempts at arresting the climate crisis.”

Eye tracker device a first in Africa
2013-07-31

Keeping an eye on empowerment

"If we can see what you see, we can think what you think."

Eye-tracking used to be one of those fabulous science-fiction inventions, along with Superman-like bionic ability. Could you really use the movement of your eyes to read people's minds? Or drive your car? Or transfix your enemy with a laser-beam?

Well, actually, yes, you can (apart, perhaps, from the laser beam… ). An eye tracker is not something from science fiction; it actually exists, and is widely used around the world for a number of purposes.

Simply put, an eye tracker is a device for measuring eye positions and eye movement. Its most obvious use is in marketing, to find out what people are looking at (when they see an advertisement, for instance, or when they are wandering along a supermarket aisle). The eye tracker measures where people look first, what attracts their attention, and what they look at the longest. It is used extensively in developed countries to predict consumer behaviour, based on what – literally – catches the eye.

On a more serious level, psychologists, therapists and educators can also use this device for a number of applications, such as analysis and education. And – most excitingly – eye tracking can be used by disabled people to use a computer and thereby operate a number of devices and machines. Impaired or disabled people can use eye tracking to get a whole new lease on life.

In South Africa and other developing countries, however, eye tracking is not widely used. Even though off-the-shelf webcams and open-source software can be obtained extremely cheaply, they are complex to use and the quality cannot be guaranteed. Specialist high-quality eye-tracking devices have to be imported, and they are extremely expensive – or rather – they used to be. Not anymore.

The Department of Computer Science and Informatics (CSI) at the University of the Free State has succeeded in developing a high-quality eye tracker at a fraction of the cost of the imported devices. Along with the hardware, the department has also developed specialised software for a number of applications. These would be useful for graphic designers, marketers, analysts, cognitive psychologists, language specialists, ophthalmologists, radiographers, occupational and speech therapists, and people with disabilities. In the not-too-distant future, even fleet owners and drivers would be able to use this technology.

"The research team at CSI has many years of eye-tracking experience," says team leader Prof Pieter Blignaut, "both with the technical aspect as well as the practical aspect. We also provide a multi-dimensional service to clients that includes the equipment, training and support. We even provide feedback to users.

"We have a basic desktop model available that can be used for research, and can be adapted so that people can interact with a computer. It will be possible in future to design a device that would be able to operate a wheelchair. We are working on a model incorporated into a pair of glasses which will provide gaze analysis for people in their natural surroundings, for instance when driving a vehicle.

"Up till now, the imported models have been too expensive," he continues. "But with our system, the technology is now within reach for anyone who needs it. This could lead to economic expansion and job creation."

The University of the Free State is the first manufacturer of eye-tracking devices in Africa, and Blignaut hopes that the project will contribute to nation-building and empowerment.

"The biggest advantage is that we now have a local manufacturer providing a quality product with local training and support."

In an eye-tracking device, a tiny infra-red light shines on the eye and causes a reflection which is picked up by a high-resolution camera. Every eye movement causes a change in the reflection, which is then mapped. Infra-red light is not harmful to the eye and is not even noticed. Eye movement is then completely natural.

Based on eye movements, a researcher can study cognitive patterns, driver behaviour, attention spans, even thinking patterns. A disabled person could use their eye-movements to interact with a computer, with future technology (still in development) that would enable that computer to control a wheelchair or operate machinery.

The UFS recently initiated the foundation of an eye-tracking interest group for South Africa (ETSA) and sponsor a biennial-eye tracking conference. Their website can be found at www.eyetrackingsa.co.za.

“Eye tracking is an amazing tool for empowerment and development in Africa, “ says Blignaut, “but it is not used as much as it should be, because it is seen as too expensive. We are trying to bring this technology within the reach of anyone and everyone who needs it.”
