UFS experimental farm helps out after veld fires rage through parts of FS

“I wish I had more to give.” These are the words of Johan Barnard, Junior Lecturer and manager on the Paradys Experimental Farm of the University of the Free State (UFS) after he donated the last of 428 bales of animal feed to a farmer from the Tierpoort area this morning (4 August 2021).

After large parts of the Paradys Experimental Farm were destroyed by veld fires three years ago and 24 famers came out to help fight the fire, Barnard believes in planting a surplus of food that would enable him to share with farmers in need. Last year, he donated bales of animal feed to farmers in the Hertzogville district whose veld was destroyed.

Sharing resources

More recently – less than a month ago – veld fires destroyed thousands of hectares of land in the Tierpoort and Fauresmith districts. Barnard, who helped to put out the fires and saw the destruction, decided to make the extra animal feed available to the farmers who needed feed for their animals.

Together with research and teaching and learning, the community is one of the university’s focus areas. “As a university, we are sharing our knowledge. The destruction brought about by the veld fires has created an opportunity where the university can also share its resources,” says Barnard.

When he made the decision to help, the feed was, however, still on the fields and had to be cut, processed, and baled. But where there is a will and a community that stand together, there is a way.

The farmers in the Koppieskraal district brought their tractors and machinery to cut, rake, and bale the sorghum and grass. BKB contributed fuel to cover the running costs of the tractors and machinery.

Once the animal feed was baled, Barnard contacted Jack Armour, operations manager at Free State Agriculture, who not only spread the word to farmers that animal feed was available, but also provided fuel to deliver the bales to the farms destroyed by fires. Since last week, volunteers have come to collect the animal feed and distribute it to the farmers.

Barnard, who believes it is difficult to put a price value on the animal feed provided by the university, says to the farmers who received it, the value of these bales is priceless.

A priceless gift

Besides the thousands of hectares of pasture destroyed during the raging fires, farmers also lost a significant number of sheep and cattle. When Leon Kruger, Lecturer in the Department of Animal Science, on the experimental farm, saw the devastation caused by the fires, he posted on Facebook that he was available to assist in treating the animals.

Together with two government veterinarians and a colleague from the Glen Agricultural College, Kruger drove hundreds of kilometres to farms in the south and southwestern Free State to help farmers treat animals affected by the fires.

He says they have treated more than 800 animals, including sheep and cattle. “We treated the animals one by one, administering antibiotics and pain medication, as well as ointment to the burned areas. This difficult ordeal was, however, a baptism of fire for all of us; we are not familiar with burn wounds. A friend in Australia helped to compile criteria to classify the different degrees of burn wounds and we treated the animals accordingly.”

“Seeing the suffering of the animals was one of the most difficult ordeals I had to experience,” states Kruger, who helped several farmers save their animals during this time where they have already lost so much.

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.”
