In the build-up to Africa Day, I noticed – among others – the slogan ‘I love Africa’ flashing in neon colours that reminded me of music videos seen on MTV in the 1980s. The idea of Africa being loved not only by those living on the continent, but also by the rest of the world, had some moments in the same decade – with pop stars coming together, for example in USA for Africa and the UK version, Band Aid. Although these attempts might have warmed some hearts, it exposed the failure of this kind of sentimentality to contribute much to the continent. Can we think of how to love and engage with the continent in a different way?

Hannah Arendt, in her Thinking journal, contemplated the question, ‘why is it so difficult to love the world.' In response to a letter from her friend and mentor, Karl Jaspers in 1955, in which he wrote to her, “You bring with you shared memories of a lost past. You bring the wide world as it is today,” she wrote “Yes, I would like to bring the wide world to you this time. I’ve begun so late, really only in recent years, to truly love the world that I shall be able to do that now. Out of gratitude I want to call my book on political theories Amor Mundi” (1985: 264). Linked to the idea of loving the world in Arendt’s work, is also that of sharing the world with each other. Arendt famously accused Nazi Adolf Eichmann of refusing to share the world with others. For the purpose of Africa Day on 25 May, I revisited these notions of loving and sharing as reflected by Arendt. I raised the question – what does it mean to love Africa and to share the continent with others?

 For Arendt, the love of the world, and linked to it – the idea of solidarity – is something quite different from equality, care, and sentiment. Love of the world, for her, entails a critical engagement with the world. What could such a love mean in relation to Africa? 

In the prologue to The human condition (1958: 5), she underscores the importance of thought and her concern about thoughtlessness, which she describes as “the heedless recklessness or hopeless confusion or complacent repetition of ‘truths’ that have become trivial and empty”. She sets out that the central theme of the book is to focus on ‘what we are doing’ and that ‘the activity of thinking’ is left out of this work. In other works, Arendt turns to the importance of thinking and, in fact, commentators have noted an ongoing tension in her work between the life of action and the life of the mind. To love the world seems to include both a thorough engagement with what we are doing and a deep contemplation of what it is that we are doing. What has always struck me in her work, is the insistence on thinking and thinking anew each time, instead of merely following what is regarded as ‘truths’. Part of what it could mean to love Africa, is not to accept or repeat trivialities and not to become complacent, but to continuously search for new ways to understand and to respond.

A tension that accompanies the tension between a life of action and a life of thinking, is that between being with others and being alone. Human plurality is for Arendt ‘the basic condition of both action and speech’ (1958:175). Becoming part of the world is like ‘a second birth’ which takes place neither by ‘necessity’ nor by ‘utility’, but by taking ‘initiative’ (177). This birth or new beginning brings forth an ‘unexpectedness’ and ‘happens against the overwhelming odds of statistical laws and their probability’. Where the latter always ‘amounts to a certainty’, new beginnings ‘always appear in the guise of a miracle’ (178). It is by way of action that we become part of the world, share the world with others, and become entangled in the ‘web of relationships’ (181). Of course, for Arendt we always begin again, and the possibility for new ways of doing and forging new relationships is always there. 

Antjie Krog (2015:219) remembers Thabo Mbeki’s speech on the day the Constitution was adopted. “On an occasion such as this, we should, perhaps, start from the beginning. So, let me begin. I am an African. I owe my being to the hills and the valleys, the mountains and the glades, the rivers, the deserts, the trees, the flowers, the seas and the ever-changing seasons that define the face of our native land.” She praises Mbeki for considering the idea of ‘being ruled’ rather than ‘being a ruler’. She finds in his speech a “kind of radical relational enfoldedness with the land” that is vastly different from most discussions from all sides of the spectrum on land. To what extent are those of us living in Africa thinking differently and innovatively, for example about land, and about how we share it with others. How can we think anew about current discourses on the African Renaissance and also decolonisation?

Arendt is clear on the importance of solitude. She underscores the importance of thinking, and slow thinking, and obtaining distance from others, and from the world of action in order to do that. In her way, she was very wary of a certain kind of solidarity based on sentimentality. Engaged citizenship, for her, is always accompanied by a critical self-reflection. Arendt (2003) warned against the urge to act in haste without thinking; she warned against withering ‘under the weight of immediacy’. In a world and a continent with so many dire needs demanding attention and action, this does not mean that we should not act with urgency, but it underscores the importance of well-thought-out responses, of not falling back on old answers.

In short, loving Africa demands of us to engage critically, not to fall back on recipes and formulas, and not to follow rules blindly; it asks us to always begin again; to seek not only for new answers, but also for new questions.

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.”
