Michelle Joubert and Jane Mpholo
Michelle Joubert and Jane Mpholo will be seen in The Island which is directed by Dr Jerry Mofokeng Wa Makhetha and Charl Henning, a Master's student.

The arts are one of the most important building blocks of any country or organisation, and it is also an important aspect at the University of the Free State (UFS). Therefore, the partnership between these two Free State institutions is important for the promotion of the arts in the province.

The Vrystaat Arts Festival is taking place on the Bloemfontein Campus of the UFS from 1 to 7 July 2019. Various UFS departments are involved in the programme, as well as in the technical and artistic planning of the festival.

UFS Drama and Theatre Arts make big contribution 

“I was involved in the planning committee and as artistic selector from the beginning of the festival, and in recent years also as member of the festival board,” says Prof Nico Luwes, Head of the Department of Drama and Theatre Arts

This department makes almost the biggest contribution to the festival, with various plays, such as The Island, which is directed by award-winning theatre maestro Jerry Mofokeng and Charl Henning, and two former students, Michelle Joubert and Jane Mamotse Mpholo in the cast, as well as technical assistance from staff and students. “Without the expertise of Thys Heydenrych as technical organiser and Brandon Hewitson as technical manager, the festival would not be possible,” says Prof Luwes. 

“Our theatres are world-class, and the work of our students as technical and theatre personnel is described as outstanding by all theatre artists.”


Thought-Leader Series, Sol Plaatje lecture, and several book conversations

Since 2018, the UFS has also been involved in the annual UFS Thought-Leader Series, which was launched by Prof Francis Petersen, the UFS Rector and Vice-Chancellor. The panel discussions deal with contemporary issues; this year’s topic is Economic Growth and Entrepreneurship for a Growing South Africa. The UFS will also present the Sol Plaatje lecture, which will be delivered by Diana Ferrus. Prof Petersen will also be part of a panel discussion with Prof Adam Habib, Vice-Chancellor of the University of the Witwatersrand, and Wandile Ngcaweni, about #FeesMustFall; the discussion will be facilitated by Ruda Landman.

The book by Prof Jan Coetzee of the Department of Sociology and Dr Asta Rau, from the Centre for Health Systems Research and Research, Narrating the Everyday, will also be discussed during the festival. So also, the book by Charl-Pierre Naude, research fellow in the Department of Afrikaans and Dutch, German and French, Die ongelooflike onskuld van Dirkie Verwey

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.”
