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.).”

The departments of Surgery and Internal Medicine at the University of Free State launched the newly upgraded Gastroenterology Unit of the Universitas Academic Hospital on 8 November 2016. Realising the need to provide state-of-the-art equipment that caters for various health needs, the unit has acquired new pieces of equipment worth R7 million. Through the equipment, a move towards the digital revolution, the unit hopes to bring about a transformative impact on healthcare service delivery in central South Africa and its surrounds.

Upgraded unit will make a difference on burden of diseases
Dr Rita Nathan, Acting CEO of the Universitas Hospital, said the increase in the number of scopes, and the improvement in technology, will facilitate improved service delivery to the community of the Free State and beyond. “This upgrade will enable the unit to make a tremendous dent in the burden of diseases in the communities we serve.”

Unit a unique feature in central South Africa

Serving a population from the Free State, Northern Cape, Eastern Cape and Lesotho; the growing demand of health services has led to an increase in the number of patients treated by the unit. This unit is unique in central South Africa as the only one providing endoscopic intervention for cases like gastrointestinal bleeding. It is also the only 24-hour gastroscopic service available in the state sector.

Improved service delivery linked to enhanced training platforms

Prof Willem Kruger, acting head of the School of Medicine, said that the upgrading of equipment will have an immense impact on not only service delivery, but also on training platforms in the latest technologies. “It important, as a university, that our doctors have the latest technology at their disposal to facilitate training. If training improves, service delivery improves. The two on inextricably linked.” he said.
