The KAT Walk mini (Omni Directional Treadmill) used to reduce and eliminate cybersickness.

An officer at the School of Nursing Simulation Laboratory of the University of the Free State (UFS) is aiming to cure or minimise cybersickness in nursing students with a popular virtual reality gaming tool.

Bennie Botha, who is acting as head of the Information, Communication and Simulation Technology at the School of Nursing Simulation Laboratory, developed a virtual environment in which nursing students use immersive virtual reality to perform a simulation scenario. This is part of his master’s degree in Computer Science and Informatics under the supervision of Dr Lizette de Wet and co-supervisor Prof Yvonne Botma.

Botha received his master’s degree with distinction during the UFS virtual graduation in October.

Cybersickness

Botha had found that some people experience cybersickness (almost like motion sickness), which is a significant issue and difficult to address. This he would now try to address with a virtual reality gaming tool – the KAT Walk mini.

According to Botha this technology has never been attempted for health-care education and is mostly used in military and pilot training and is very popular as a gaming platform for hardcore virtual reality gamers.

“To test and provide a possible solution I am going to incorporate the KAT Walk mini (Omni Directional Treadmill – almost like the Ready Player One concept) into which students are strapped and they can physically walk and turn around without the need for large open spaces.

“With this I will try and determine whether it decreases or even eliminates cybersickness due to sensory mismatch while using immersive virtual reality. I wanted to provide possible evidence of what causes cybersickness and want to enable virtual reality as an educational tool, not just for gaming. I think immersive virtual reality has a bright future if the kinks (of which the biggest is cybersickness) can be minimised,” says Botha.

Getting funding

He successfully applied for funding in 2020 and received R150 000.

“I must say I was surprised when I got the approval letter. I thought that due to the economic status it would not go through, but I was really glad when I got the approval as this is my dream and I love working with virtual reality for health care. The grant has made my dream come true, especially considering that this sounds more like something from science fiction,” says Botha.

The project started in November 2017 when Botha first conceptualised the idea and took it to Dr De Wet. He then started it as a masters’ project in 2018 and completed it at the end of 2019.

An equal opportunity for students

Botha says immersive virtual reality gives students more time and a more accessible platform where they can practise their skills as it is easy to use and easy to set up compared to other modalities of simulation. But the biggest task is developing a usable virtual environment that gives students more time to practise and increase their theory and practical integration which is key to providing highly skilled health-care professionals.

“By seeking and possibly implementing the new research, I aim to provide students an equal opportunity to partake in immersive virtual reality simulation as it currently excludes people who are prone to high levels of cybersickness. This means they cannot benefit from the same opportunities as other students do.

“I believe it can help all nursing students in SA and Africa as it is much more cost-effective than high-technology manikins and is easier to set up and access with much less manual input required to make it work (apart from the initial development.).”

Expert in Africa Studies debunks African middle class myth

Until recently, think tanks from North America, the African Development Bank, United Nations Development Plan, and global economists have defined the African middle class based purely on monetary arithmetic. One of the claims made in the past is that anyone with a consumption power of $2 per day constitutes the middle class. Following this, if poverty is defined as monetary income below $1.5 a day, it means that it takes just half a dollar to reach the threshold considered as African middle class.

Prof Henning Melber highlighted the disparities in the notion of a growing African middle class in a guest lecture titled A critical anatomy of the African middle class(es), hosted by our Centre for Africa Studies (CAS) at the University of the Free State on 4 May 2016. He is an Extraordinary Professor at the Centre, as well as Senior Adviser and Director Emeritus of the Dag Hammarskjöld Foundation in Sweden.

Prof Melber argued that it is misleading to consider only income when identifying the middle class. In his opinion, such views were advanced by promoters of the global neo-liberal project. “My suspicion is that those who promote the middle class  discourse in that way, based on such a low threshold, were desperate to look for the success story that testifies to Africa rising.”

Another pitfall of such a middle-class analysis is its ahistorical contextualisation. This economically-reduced notion of the class is a sheer distortion. Prof Melber advised analysts to take cognisance of factors, such as consumption patterns, lifestyle, and political affiliation, amongst others.

In his second lecture for the day, Prof Melber dealt withthe topic of: Namibia since independence: the limits to Liberation, painting the historical backdrop against which the country’s current government is consolidating its political hegemony. He highlighted examples of the limited transformation that has been achieved since Namibia’s independence in 1990.
