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.).”

Emotional health of vulnerable children needs urgent intervention
2014-02-04



In South Africa, thousands of children under the age of 18 are orphaned as a result of HIV/Aids. Experts are worried that these orphans and vulnerable children will experience serious socio-emotional problems and behaviour disorders, should urgent intervention programmes not be implemented urgently.

A study was undertaken by the Centre for Development Support at the UFS, in conjunction with Stellenbosch University and the Houston University in America. The research found that in the Free State province alone, about 15% of orphans and vulnerable children showed signs of psychiatric disorders. Almost half of the children in the study showed signs of abnormal or maladjusted behavioural functioning.

The research team believes that the South African government and the numerous non-governmental organisations put too much emphasis on the physical needs of orphaned and vulnerable children and that their socio-emotional or mental wellbeing receives very little attention.

The nominal financial grant is a welcome relief for some of the needs of this risk group. Researchers are worried, though, that the lack of reliable and culturally-sensitive diagnostic methods for the early detection of psychiatric disorders may pose a challenge when the children reach puberty.

The current study is focusing on the detection of emotional behavioural problems even before adolescence. Questionnaires were distributed across the Free State at clinics, schools and non-governmental organisations dealing with these children. The questionnaires enabled researchers to establish the children's socio-emotional needs.

"Overcrowding in houses where orphans and vulnerable children often live is directly linked to poor socio-emotional health in children," says Prof Lochner Marais from the Centre for Development Support. "The state institutions offering programmes for orphans and vulnerable children overemphasise the physical and/or financial needs of these children. The programme provides, for example, food for the children, grants for the [foster] parents, assistance with school clothes and ensures clinic visits for the children. Of these, only the supply of food has a direct impact on the improved mental health of children."

The study provides, for the first time, a profile of the state of mind of this group, as well as the emotional impact of HIV/Aids – an "urgent matter" according to Dr Carla Sharp from the University of Houston's Department of Psychology. According to Dr Sharp, much more could be done to assist foster parents in addressing the emotional needs of these children. The early detection of behavioural disorders should be the key in intervention programmes.
