Two of the University of the Free State (UFS) SARChI Research Chairs have been included in the 2nd edition of Research.com ranking of the best scholars in the field of Social Sciences and Humanities.

Prof Melanie Walker from the UFS Higher Education and Human Development research group and SARChI Chair: Higher Education and Human Development, and Prof Ivan Turok, from the South African National Research Foundation, who hold the Research Chair in Strengthening Urban Economies: People, Place, Production and Policy, are ranked 41st (ranked 5 286 in the world) and 20th (2 825) in South Africa respectively.

According to the Research.com website, the best scientists ranking is a credible list of leading scientists from the field of Social Sciences and Humanities, established by means of a meticulous analysis of 166 880 scholars determined from multiple bibliometric data sources. For this discipline, as many as 15 317 researchers were analysed and their position in the ranking is based on a researcher’s D-index (Discipline H-index), which only includes papers and citation values for an examined discipline.

The success of a community

As a SARChI Chair in Strengthening Urban Economies: People, Place, Production, and Policy, Prof Turok explores how cities can drive economic growth and foster inclusive development in South Africa. His research analyses the factors contributing to the success of certain cities over others and identifies policies and practices that can enhance conditions for citizens and communities

He says this “pleasant surprise” (being ranked 20th in South Africa in the field of Social Sciences and Humanities) follows years of scientific work and writing.

“Research has also been a labour of love and rewarding in itself. It has fuelled my natural curiosity for learning more about the world, and I have had opportunities to visit places and meet people I would never have had otherwise,” says Prof Turok.

What it takes to be a researcher

Although one can learn the required skills and capabilities to be a good researcher, Prof Turok says having a natural yearning for knowledge and an intrinsic curiosity about the real world is helpful to have a long research career. “Careful mentoring and sound teachers are vital to become an effective researcher.”

He firmly believes research should be relevant to the society in which it is located – especially in a developing country like South Africa.

He continues by saying: “It should shed light on and help to understand the major problems and opportunities facing society, using the tools and techniques available to that particular discipline.” This honoured researcher says researchers should inform societies using simple terms and engage in discussions on matters it faces.

“Researchers should be outward-looking and interact constructively with policy-makers and practitioners to improve public policy while maintaining a healthy dose of scepticism about the intentions of the political elite and other powerful interests.”

When analysing the reasons behind varying levels of economic growth and inclusive development among cities, it is crucial to consider a diverse range of indicators. “Relying solely on a few narrow indicators can be misleading," says Prof Turok.

Indicators to take into consideration include: The economic productivity of the city (output per person) and the average income level, the level of employment in relation to the working-age population, which enables individuals to support themselves and their families financially, and the level of investment, which determines future growth, employment, and income levels.

The value of research

Prof Turok suggests that the government could play a significant role in strengthening urban economies and reducing inequalities by devolving more powers and resources to metropolitan municipalities as the effective coordination of housing and transportation investments is crucial for achieving economic growth and social inclusion in cities. He also recommends aligning the programmes and investment projects of provincial authorities and state-owned enterprises (SOEs) with those of the metropolitan areas.

“Currently, there is a disconnect between the activities of many SOEs and the interests of cities. For example, there is a considerable amount of vacant and underused land in well-located urban areas owned by SOEs, which they refuse to transfer to metros for housing purposes (highlighting the relevance of land reform in cities). Another example is the Sector Education and Training Authorities (SETAs), which operate in silos and do not align their training programmes with the needs of employers in cities,” explains Turok.

Being an internationally recognised expert in his field, Prof. Turok is regularly asked to advise esteemed organisations such as the United Nations and the African Development Bank. Prof. Turok, a former finalist for the National Science and Technology Forum (NSTF) Lifetime Achievement Award in 2021, will serve in this significant role until 2025.

Focusing on Education

Prof Walker, a distinguished scholar in the field of education sciences with an A1 rating from the National Research Foundation (NRF) – which funds SARChI – focuses on the profound impact of apartheid on education and civic life. She concentrates on (higher) education, primarily in the Global South, and addresses the intersecting research and practice challenges of decolonisation, methodology, inequalities, and justice.

This former professor of Higher Education at the University of Nottingham currently holds the esteemed position of UFS Distinguished Professor. She has supervised the production of 23 doctoral theses on higher education and human development since 2016. Additionally, she has delivered numerous keynote speeches worldwide and is an acclaimed author of books and journal articles within her area of expertise.

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.”
