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.).”

Double achievement for Prof. Paul Grobler

Early this year, two journal editions appearing almost simultaneously in Europe featured cover photographs based on papers by Prof. Paul Grobler of the Department of Genetics and his collaborators.

These papers stem from collaborations with Prof. Gunther Hartl at the University of Kiel (Germany) and Dr Frank Zachos from the Natural History Museum in Vienna (Austria). Both papers cover aspects of the genetics of southern African antelope species.
 
The first paper appeared in the Journal of Zoological Systematics and Evolutionary Research” (from the Wiley-Blackwell group). This was titled “Genetic structure of the common impala (Aepyceros melampus melampus) in South Africa: phylogeography and implications for conservation”.
 
In this paper, the team analysed impala from various localities in South Africa to determine the relationship between distribution and genetic structure. The results suggest a clear relationship between genetic characteristics and habitat features that regulate gene flow.
 
The second appeared in the journal Mammalian Biology (from the Elsevier group), with the title “Genetic analysis of southern African gemsbok (Oryx gazella), reveals high variability, distinct lineages and strong divergence from the East African Oryx beisa”.
 
Here, the researchers looked at various aspects of the genetics and classification of gemsbok. Among the notable findings is that gemsbok populations on the game farms studied are less inbred than previously predicted.
 
Proffs. Grobler and Hartl initiated these projects on gemsbok and impala, with sub-sections of the research later completed as M.Sc. projects by students from both South Africa and Germany.
 
Prof. Grobler has been involved with aspects of the population genetics of various mammal species since the early 1990s, and continued with this line of research after joining the UFS in 2006. Current projects in this field include work on wildebeest, vervet monkeys and white rhinoceroses.
