All South African citizens are by now aware of the global pandemic caused by the COVID-19 virus. Our president, Cyril Ramaphosa, placed the entire country in a state of lockdown to limit the spread of the virus in South Africa. Schools, tertiary institutions, churches, and numerous businesses (which do not provide essential services) had to close. The lockdown aims to ensure that citizens stay at home, isolate themselves from others, and that those who can work from home should do so. The consequence and reality, however, is physical and social isolation, which of course also means that many people are currently alone and lonely.

Working from home
There are several benefits to working from home; for example, you can manage your own time, work in comfortable clothes, and you can work undisturbed and with less interruptions. Although the lockdown – and thus social isolation – will only last for (maybe) 21 days, there are psychological disadvantages associated with social isolation. Many people could soon become discouraged and demotivated because of the time away from others due to social isolation. Social isolation is the absence of social interaction, contact, and relationships with loved ones, colleagues, strangers, and even society as a whole. Humans, by nature, are social beings who strive towards social interaction with others, and social interaction is essential for people's well-being and survival. Although it is also natural to occasionally seek alone time, the effect of social isolation can have negative consequences for the emotional well-being of individuals.

Consequences of social isolation
Studies have shown that long-term social isolation has dire consequences for people's physical and mental health, such as increased risk of premature death and higher tendencies towards depression. Still, social isolation – even for a few weeks – can also have a negative psychological impact on people's lives. Social isolation can lead to feelings of despair and loneliness, depression, anxiety, substance abuse, and sleep difficulties. Furthermore, in times of social isolation, individuals tend to exhibit more forms of unhealthy behavior than usual, such as smoking and drinking more alcohol. Feelings of loneliness tend to worsen when individuals are isolated with people with whom they do not have a close relationship and, therefore, loneliness becomes a more significant struggle during times of social isolation. This can turn into a vicious cycle, leading to more loneliness and depression if not dealt with. During these isolation periods, individuals may even become complacent, and consequently do not have goals and routines.

Social isolation will, however, affect people differently. More extroverted people will long for social engagement with others and might feel as if they want to climb the walls. They will just want to go shopping and spend time with others. More introverted individuals may enjoy this alone time and spend time taking long baths and reading books. However, everyone will start to experience social isolation negatively at some point. Families will, for example, not be used to these extended periods together, and this may lead to increased conflict between family members. Individuals with big homes can spend time in their gardens and exercise on their lawns, but what about those individuals living in overcrowded flats or informal accommodations. Such individuals may be more inclined to experience depression, anxiety, and loneliness. Individuals with drinking and smoking habits may become more dependent on these substances during the lockdown. Also keep in mind those individuals who have small children who are now home for several weeks and need to be kept busy and entertained by their parents. Parents are not used to being responsible for keeping their children busy productively.

Socializing through social media
People might still be fine and feel good now, but we have not yet reached the halfway point of the lockdown, and how will individuals cope if the lockdown is extended. There is, of course, hope. It is important to remember that although people are currently isolated, they can still attempt to be social by using various forms of social media. Recent studies have shown that individuals may experience less loneliness when interacting with others through various forms of social media. Accordingly, individuals need to make more contact with others and reach out to those that they have not heard from in a while. Social interaction is crucial, as many of us need social interaction to cope with daily challenges. However, also beware of negative content or fake news. Social interaction via the internet might not fulfil everyone’s needs as with interpersonal communication and interaction, but it still allows us to experience a sense of congregation and community.

Stay positive
The reality is, however, that many people also do not have access to the internet and social media, and therefore cannot communicate with others. It then becomes essential that people should continue with certain routines in their lives and to not just sit in front of the television. People still have to set goals (even smaller goals) for themselves and try to achieve them. Everyone should try to change their perspective by trying to stay positive. People need to attempt any form of exercise and keep their minds occupied with books or brain games. Fortunately, when it comes to children, most schools have provided parents with study material to keep their children busy educationally. Alternatively, parents should create some form of structure and routine for their children during the lockdown. Families can play board games and create their own fun activities. Children should also be allowed to engage with their friends via social media if they become lonely. And parents should allow their children to share their worries and concerns openly. Individuals need to be prepared, because when this mandatory period of isolation ends, everyone will have to resume their normal activities.

Get help
If not addressed, these experiences of overwhelming loneliness, sadness or lack of meaning may continue long after the lockdown has ended. Individuals who experience depression and loneliness after the lockdown should reach out to others, try to eat healthy foods, do fun things, and exercise more. Such individuals should also consider contacting mental healthcare professionals for assistance. They can also visit the South African Depression and Anxiety Group's website or Facebook page for help.

Social distancing is vital at this stage, but as South African citizens, we must remember that we are not going through this alone. We are isolated from others, but together we are all fighting the same battle against COVID-19.

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.”
