We are pleased to host Bertus Jacobs in our second episode of the Voices of the Free State podcast series. As Chief Technology Officer at IoT.nxt. (Internet of Things), Bertus’ mind is constantly searching for new techniques, and imparting these to his team of developers. Evident from his ‘always on’ approach, Jacobs has optimised his passion for turning ideas into mainstream realities. He co-founded a successful software company, CSS Software, which saw its humble beginnings grow from Bloemfontein-based to an international-footprinted company. CSS Software is regarded as having some of the most innovative products in its market segment and was acquired by a JSE-listed group.

François van Schalkwyk and Keenan Carelse, UFS alumni leading the university’s United Kingdom Alumni Chapter, have put their voices together to produce and direct the podcast series.  Intended to reconnect alumni with the university and their university experience, the podcasts will be featured on the first Monday of every month, ending in November 2021.  Our featured alumni share and reflect on their experiences at the UFS, how it has shaped their lives, and relate why their ongoing association with the UFS is still relevant and important. The podcasts are authentic conversations – they provide an opportunity for the university to understand and learn about the experiences of its alumni and to celebrate the diversity and touchpoints that unite them.

While studying towards his BScHons (Computer Science) at the University of the Free State, Bertus developed an SDK (Software Development Kit) with low-level integration into various graphics hardware.  

Bertus has researched many ways of contributing to the growing IT industry – from developing point-of-sale systems that still run today, qualifying as MCP and MCSE, engineering telematic and biometric solutions for clients (UFS was one of them). After being approached to consult in developing a solution for the government, his search for a certain hardware problem and his expertise in the IT realm resulted in his invention of a controller and the birth of the RAPTOR.  Reports that took eight weeks to compile previously, are now at the fingertips of those who need it – all through data harvesting and dashboarding that combines software and hardware. The world-changing RAPTOR delivers a complete IoT solution, which has been internationally validated as being at the forefront of the emerging IoT wave.  IoT.nxt was named Best Commercial and Best Overall Winner at the MTN Business M2M Awards in 2017.  

Stay tuned for episode three to be released on 5 April 2021.

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.”
