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.).”

UFS awarded five South African Research Chairs

The UFS was awarded five SARChI (South African Research Chairs Initiative) research chairs, the main goal of which is to promote research excellence. In addition, there has been an increase in the rating of the University’s researchers as the result of raised academic standards over the past few years, in line with the UFS’s Academic Project. As of 2016 the UFS has 127 NRF-rated researchers.

The following research chairs have been awarded to the UFS since 2013:

Prof Hendrik Swart from the Department of Physics is the research chair of Solid State Luminescent and Advanced Materials (2013-2017). Prof Swart’s research may assist in reducing vulnerability and contributing to poverty alleviation by providing affordable lighting for people in rural areas through fabricating phosphors and the development of nanophosphors.

Prof Maryke Labuschagne from the Department of Plant Sciences is the research chair of Disease Resistance and Quality in Field Crops (2016-2020). Prof Labuschagne believes that food security is one of the key factors for stability and prosperity on the continent. Her research and that of her students focuses on the genetic improvement of food security crops in Africa, including such staples as maize and cassava.

Research Chairs have been designed, to attract
and retain excellence in research and innovation
at South African universities.

Prof Melanie Walker, from the Department of Higher Education and Human Development, was awarded the research chair from 2013 to 2017. Prof Walker’s research interrogates the role of higher education in order to advance human development and justice in education and society, especially in relation to severe inequalities and poverty. Significantly, it asks what kind of societies we want, what is important in a democratic society, and thus, what kind of higher education is valuable, relevant and desirable.

Prof Felicity Burt from the Department of Medical Microbiology was recently awarded the research chair from 2016 to 2020, to investigate medically significant vector-borne and zoonotic viruses currently; to define associations between these viruses and specific disease manifestations that have previously not been described in our region, to increase awareness of these pathogens; to further our understanding of host immune responses, which should facilitate development of novel treatments or vaccines and drug discovery.

The Humanities without Borders: Trauma, History and Memory research chair was awarded from 2016 to 2020. The Institute for Social Justice and Reconciliation will use this research chair to investigate historical trauma within two African contexts – those of South Africa and Rwanda. The research hopes to bring insight into the role that memory plays in the formation of the experience of trauma, and to bring about healing of the trauma.

Research Chairs have been designed by the Department of Science and Technology, together with the National Research Foundation, to attract and retain excellence in research and innovation at South African public universities.
