What does it mean to say one has a right to something, such as access to housing or to protest or to property? What are human rights? What do they ‘do’?

One often hears of human rights being asserted as if they give one an absolute claim to something specific and discrete, which can be enforced against anything and everyone else, irrespective of the impact on the interests (and rights) of others, as well as broader public goals or values.

Perhaps the clearest example of this was the way in which the right to ownership of land was understood under apartheid property law. Ownership then was an absolutely exclusive right: it entitled its holders to exclude everyone else without a countervailing right from their land, irrespective of circumstance or context. All a landowner had to prove before a court to obtain an eviction order if they sought to evict someone from their land, was that they had the right (owned the land) and that those they sought to evict had no countervailing right in law to be on the land. If the right was proved in this way, the remedy of exclusion through eviction followed automatically – the court had to grant the eviction order.

Constitutional right to peaceful protest

A more recent example of this view was on display in the way in which members of parliament complained about their removal from the house when they attempted to shut down the President’s State of the Nation Address through protest action. Many responded by saying their removal was unjustified because, by trying to stop the address from proceeding, they were exercising their constitutional right to peaceful protest. The assumption underlying this response is that the right to protest peacefully and unarmed entitles you to protest peacefully and unarmed in any way you see fit and regardless of the consequences for other people and for society at large.

With this view of rights, a right bestows on its holders a sphere of absolute inviolability – an abstract space within which they can do what the right entitles them to do (protest, hold property, speak, associate or whatever), subject to nothing and no-one else, with no limitations. Rights are seen as instruments through which to separate ourselves from other people and unilaterally impose our will and our interests on others. Rights operate as trumps, boundaries, conversation stoppers.

Understanding human rights

Fortunately, our constitution embodies a different vision or understanding of human rights. In various ways, our constitution makes it clear that what exactly our human rights entitle us to do, or have, or experience, is never abstractly fixed, immutable, or absolute, but must always be determined anew within context. Whenever we seek to exercise one of our human rights, its precise contours and limits must be determined in light of the circumstances prevailing at the time we seek to exercise it; the history of our country; the impact that our exercise thereof will have on the rights and interests of other people; and how our conduct in terms of the right aligns with the public interest and broader constitutional goals.

In this view of rights, our understanding of the right of ownership (which is of course not one of the human rights proclaimed in our constitution but is only indirectly protected in Section 25 of the Constitution) has been moulded into something entirely different from the apartheid conception. Landowners no longer have absolute, exclusive control over their land that simply arises from the fact that they have the right to ownership. If landowners today want to remove people occupying their land without any legal right to do so – in addition to and after proving their ownership – they must persuade a court that eviction would be just and equitable in light of all relevant circumstances (prevailing circumstances; interests of others, including the occupiers of their land; the public interest; constitutional goals) before they will succeed.

WATCH: The Power of Human Rights 




Building democracy

Likewise, if we seek to exercise our right to protest – in order to know what we would be entitled to do in terms of that right – we must consider how our protest will affect the rights and interests of others and whether that impact can be justified, and how the manner and form of our protest squares with constitutional goals such as building democracy. Equally, of course, if others object to our protest because of its impact on their rights and interest, they will have to contextualise their attempt to exercise their right to education, or academic freedom, or freedom of movement in light of our interests, the prevailing circumstances, the public interest, and constitutional goals such as fostering democracy, freedom of association, and freedom of speech.

That is, instead of rights in our constitutional order being abstract spheres of inviolability that can be exercised against others to protect or enforce our interests without consideration of context, keeping us apart, they are mechanisms to enable us to live together, to find accommodation between our disparate, perhaps conflicting, but often overlapping interests and concerns.

What is it then that our human rights do for us or entitle us to? Whenever our human rights-related interests are at stake, or if we rub up our fellow human beings with whom we cohabit the wrong way when our interests seem to clash, they entitle us to be taken equal account of. They require others (most importantly those in authority, usually the state) to include us and have concern for our interest, equal to the concern for others, in the conversation about what should happen and what we may or may not do. In this sense, rights do not keep us apart or stop conversations. Instead, they are acutely democratic mechanisms, making it possible for us to live together. ‘Only that?’, you may respond – but this is no small thing.

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.”
