2019 is the year of the national general elections in South Africa – 8 May is when South Africans will have an opportunity to vote and to impact change, hopefully for the better.  But the beginning of 2019 saw the resurfacing of student protests, mainly driven by issues of registration, challenges associated with the National Student Financial Aid Scheme (NSFAS), student accommodation, safety of students (off-campus), insourcing, and various other issues influenced by local institutional context.
  
Challenges for university vice-chancellors

Our Constitution promotes protest, but emphasises the peaceful nature thereof, and that it should not infringe on the rights of others or damage property.  However, the protests experienced by the majority of higher-education institutions in South Africa in 2019 was exactly the opposite – disruption of classes, intimidation and victimisation, disrespect and often destruction of property.  A notion or approach of almost entitlement, even if the university management was willing to engage and was constantly open to assess ways and means to resolve these issues.  The drive for these protests was short-term gains, totally divorced from the long-term implications on the institution’s welfare.  This puts the university management under enormous pressure, sometimes feeling exposed and alone in ensuring that the institution remains sustainable – financially, as well as from an infrastructure and human resource perspective.

There is no doubt that the upcoming elections are used for political lobbying, tactical manoeuvring, and undermining to demonstrate political muscle – all playing out on our university campuses and to be managed by university vice-chancellors (VCs) and their executives.

Are universities not the pillars of knowledge in society, the providers of human capital and new knowledge to ‘lubricate’ our economy, the delivery of the next generation of professionals who will shape how our society, or a new South African citizenship should look like?  If this is the case, who are protecting our universities, who is standing with our VCs and university executives to ensure that our universities remain the beacon of hope for generations to come?  What is expected of VCs and university management in situations where there is a continual push for more, and if the response is not positive or immediate, protests, and in most instances violent and criminal behaviour. My personal view is not to securitise or militarise our campuses, but to resolve these issues through continuous engagement – but what if protests becomes violent and criminal?  What if disruptions challenge or threaten students, staff, infrastructure, and the academic project?  Student leaders seem to have forgotten the engagement with university leadership through a principle of ‘give and take’, always balancing short-term wins with the long-term sustainability and growth of the university.

Although universities often have their own internal disciplinary processes, these are slow, and the transgressors are often repeat offenders.  The sanctions are also in many cases restorative – which I believe it should, but to what end?

Help needed to ensure sustainability of universities 

We have seen how weak leadership, corrupt practices, and inadequate government funding have had a detrimental effect on the overall state of universities in the rest of the continent.  This has led to the outflow of excellent academics from the continent to elsewhere on the globe – a loss for the university and the continent!  Universities, although resilient, are also fragile as a system.  The protests associated with the #Rhodes and #FeesMustFall movements, together with the continued protests in 2019, run the risk of putting South African universities on a similar trajectory.  A fragile university system, when broken, will take decades to be restored.

Therefore, if universities are important institutions for society and the country, should there not be more concerted efforts from government and society to ensure that our universities remain strong and competitive? Although I do not offer a specific solution per se, should government, together with university leadership, staff, and students not be more vocal, thinking of a mechanism to curb and/or disallow immediate disruptions and the breakdown of infrastructure, and show visible support to university leadership in an effort to continue the academic project?  Our universities are performing extremely well against global counterparts, keeping in mind the current (and the past 10 years) South African economic growth and investment constraints with respect to infrastructure, research, and high-level scientific equipment – even a more critical argument to protect these national assets.

Academic project remains crucial

I am not for a moment belittling the issues raised by students and student leaderships – in fact, most, if not all of these issues, are legitimate.  I can understand the frustrations of the students – the slow pace of transformation, social integration, and often the lack of urgency in executing agreed decisions within the higher-education sector.  However, I am questioning the type of reaction or action exhibited by the students if, for similar legitimate reasons (through proper engagements), student demands cannot be completely met by university leaders.

In the final analysis, South Africa needs strong universities which are competitive – the country needs appropriate skills to enable and support the economy.  Also, universities need to listen to the student voice – deal with their concerns in a fair and socially-just manner; but as a sector with all its stakeholders, we need to ultimately respect the academic project and the infrastructure (physical and human) which support it.  We cannot afford party-political dynamics to ‘abuse’ the university campus in a way that can destroy the fibre of our higher-education system.  This will be catastrophic for South Africa, and I believe for the continent.

I call on government, voices in society, fellow students, student leadership, and staff to support university management openly, pro-actively and firmly, so that our universities remain places of intellectual engagement and discovery, places where different views are respected and heard, and by ‘jealously guarding’ the institutions as ‘country resources’, responding to all stakeholders’ concerns in a fair and just manner.

It is only then that universities ‘regain’ their rightful place in society, educating the next generation of scholars and professionals, advancing new knowledge, and purposefully disseminate and apply these to society – contributing to ‘lubricating the economy’ and to the betterment of the quality of life of our people!

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.”
