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.).”

“Life is too short to abandon what sets you on fire. Find your passion, work hard at it and be great. You will never look back and wish otherwise.” These are the words that postgraduate student Charissa Worthmann lives by, and which have encouraged her to pursue her dream of being a gymnast.

Humble beginnings
After undergoing heart surgery earlier this year, Charissa bounced back stronger than ever. She went on to win five regional gold medals at the Free State Gymnastics Championships in February 2017 and was also crowned Free State Victrix Ludorum. In October 2016 she won a gold medal for her apparatus routine at the South African GymnasticsChampionships.

Charissa, who is currently doing her honours in Biokinetics at the University of the Free State (UFS), said coming from a small town was not always an advantage. “I come from a small town in KwaZulu-Natal where there are not many opportunities. Therefore there was no gymnastics. I found my natural talent, but never had the opportunity to develop it before coming to the UFS.”

Inspired by lecturer
Charissa’s inspiration is Prof Liesl van As, Associate Professor from the Department of Zoology and Entomology. She is also completing her undergraduate Zoology modules to later complete her postgraduate studies in Zoology. “As a student, our lecturers don’t often realise it, but they shape us to aim higher in life.”

According to Charissa, Prof van As is a woman of pure brilliance who has aspects that every woman should aspire to: Beauty, intelligence and a drive to succeed. “I owe a vast majority of my success to her, because even though she may not realise it, her motivational attitude and success in life drove me to succeed in areas of my life.”
