Lucien le Grange, architect and urbanist, delivered the 32nd Sophia Gray Lecture this year. The online event was hosted in the Oliewenhuis Art Museum, where an exhibition of his work was also on display.

The Department of Architecture at the University of the Free State (UFS) presented the 32nd Sophia Gray Memorial lecture at the Oliewenhuis Art Museum on 26 August 2021.

The speaker at this year’s event – presented online – was Lucien le Grange of Lucien le Grange Architects and Urban Planners. Some of his work includes the Nelson Mandela Gateway to Robben Island, the Prestwich Street Memorial, and the architecture and urbanism of District Six. 

Le Grange was part of the staff of the Cape Town School of Architecture from 1978 to 2011, where he taught Design and History and Theory of Architecture at undergraduate and postgraduate level. Most of his work was also conducted in the Western Cape.

Purposeful thinking and purposeful action

He believes a time such as this, marked by so many environmental and public health challenges, demands of us purposeful thinking and purposeful action. “The recent social disruption in our country specifically requires honest reflection of the kind of social system we seek to create for ourselves as a nation.”

“We are at a crossroads that gives us an opportunity to seriously and honestly confront our shortcomings as a society. We need to find ways to restore confidence in ourselves and to fashion a new national urban development strategy,” he continues.

Le Grange is of the opinion that the social unrest in July is important for architects and urban designers to reflect upon. He elaborates: “In different ways, the sight of unrest stretching from Phoenix to Soweto shows that the apartheid city format remains very much intact. There has in fact been very little reconstruction and development. Our cities remain unsustainable, inequitable, and inefficient. These spaces are still conglomerations where there is no choice, no sense of place, no sense of safety, and no sense of security.”

For him as an architect and urbanist, the images of freeway landscapes summarise much of the shortcomings of our South African cities. He feels that it demonstrates a dependency on the private motor vehicle at the expense of safe and secure public transport. “It illustrates an environment full of physical barriers, which segregates communities in the isolated, monofunctional informal settlements that populate our urban landscapes,” he says. 

Le Grange is convinced that this condition – all over our nation’s towns and cities – is an inditement against our dysfunctional state. “It is astounding that 27 years since the birth of our democracy, the apartheid city planning model still prevails,” he says. 

Projects contributing to the social fabric

Much of the work he displayed during the lecture was done in the first decade after 1994. He says in the early years of our new democracy, the aspirations and ambitions of the RDP somehow influenced how our social services programmes were conceived and how they were delivered. The projects were executed in a manner that allowed greater social interpretation in terms of its design and execution. Facilities were expected to serve a broader social role, and its construction very often incorporated training and employment opportunities. 

“It was an exciting time, although short-lived.”

He grouped his work into three overlapping areas of concern – architecture and the city, architecture and history, and architecture and community – which have informed the understanding of various contextual challenges and inspired his design ideas. 

“These areas have assisted us to develop strategies that assist city building, urban design, engagement with user communities, the making of buildings, and the treatment and use of building materials,” he says. 

Talking about architecture and the city, he discussed the urban design for the old Klipfontein Road Corridor. The project consists of an activity corridor along 35 km of landscape and is envisioned as a space that will allow for various development opportunities. The project also aims to break down the barriers that divide much of the urban landscape in Cape Town and to populate it with nodes, coinciding with activity areas such as a stadium, schools, or shopping malls.

Le Grange’s portfolio also includes projects that investigate a revitalisation of destroyed and forgotten sites or landscapes in District Six.

As an urbanist, he investigates how cityscapes should perform to retain integrity and a kind of density that allows mixed-use development. He points out some of the opportunities that come with dense urban living, offered by structures such as major routes, punctuated with urban landmarks and streets. Multi-purpose in their function, he believes streets are social spaces where children can play and where communities can gather during a carnival or a protest. “It is also a place of finer intimacies, from which to be seen and into which one can look onto,” he adds. 

“One must also remember the existence of natural features; in this case the presence of Table Mountain that is like a mantle wrapped around Cape Town,” says Le Grange.

The declaration of the Group Areas Act in 1966 meant the end of this vibrant and highly liveable quarter in the city, and was followed by a period of destruction, implemented between the mid-1970s through to the 1990s.

Le Grange says there was, however, not a full removal. Places of worship and the schools were still occupied. When requested to develop a first-phase housing development for people to return to this area, it was around these particular social spaces that he worked. 

The first nine houses built for this project were privately funded by the developers and were constructed without any approval from the authorities. The occupants of these houses were the first claimants to be moved back to District Six after being forcibly removed by the apartheid regime. 

The Klipfontein and District Six projects are but two on the list of projects in which Le Grange – who believes all of humanity has a right to a life of dignity – was involved to better the lives of communities around him. 

Other projects he touched on during his lecture include the Genadendal Heritage, Conservation, and Restoration project, the Ocean View Community Hall, and the Hanover Park Market.

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.”
