Two South African government departments have granted the University of the Free State’s Department of Pharmacology a combined amount of R15 million for the establishment of four tea farms in the disadvantaged communities in the North West and Eastern Cape Communities.

The head of the project Prof Motlalepula Matsabisa at the Department of Pharmacology said that that Department of Environmental Affairs (DEA) has granted an amount of R10 million for the community research in the respective provinces.

This grant is a top up to the R5 million they received from the Department of Science and Technology for the “community implementation on indigenous health infusions or teas as commonly known.”

The DEA will in the near future sign a Memorandum of Agreement (MOA) with the university.


Tea project set to empower communities


“The project is to implement and build structures in the four communities we work with in the North West and Eastern Cape,” he said.

The identified areas for the project are in the Eastern Cape towns of Alice and Idutywa as well another two North West communities in Zeerust.

Prof Matsabisa indicated that the project will be a manifestation of “how science can contribute to economic growth, poverty alleviation and job creation.” 

“It was very interesting to have discovered that some French and German companies have already displayed interest in the projects,” he said.

He stated that a project of this nature is a good initiative by the UFS and it will also show that the university’s research activities are national. “We have been researching and developing indigenous teas which have now attracted interest locally and internationally by huge companies such as Nestle, Tiger Brands, Moringa World etc,” he said. 


Taking it slowly


At the initial stages of the tea farming project, Prof Matsabisa said they would start in small portions of utilising five hectares in each of the four projects and as the project gains momentum, they would expand.

Prof Matlabisa said that an environmental impact assessment has already been conducted and they were waiting for the DEA to give them a go ahead for the land preparations.

Eye tracker device a first in Africa

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.”
