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 Rector takes three months sabbatical leave
2008-05-05

The Rector of the University of the Free State (UFS), Prof. Frederick Fourie, has announced that he will be taking three months sabbatical leave as from Thursday, 8 May 2008.

Prof. Fourie recently made the request for sabbatical leave to the Chairperson of the UFS Council, Judge Faan Hancke. The request was approved given the fact that Prof. Fourie has occupied a number of demanding top-management posts for almost nine years, during which time he had to manage a number of major changes at the UFS.

According to Prof. Fourie, he originally wanted to go on sabbatical leave in the second half of 2007 before the start of his second term as rector, but it was not possible at that stage.

He was last on sabbatical in 1996 before he became Dean of the Faculty of Economic and Management Sciences in 1997 and Vice-Rector: Academic Operations in 1999.

He could not take his next five-yearly leave because in the post of vice-rector he was tasked with leading the financial-turnaround strategy for the UFS from the year 2000 and had to act as rector when the previous rector, Prof. Stef Coetzee, was on sick leave. Since being inaugurated as rector in 2003, there was also no opportunity to take leave as a result of the many key projects and urgent initiatives.

The Vice-Rector: Academic Operations and vice-chairperson of the Senate, Prof. Teuns Verschoor, will be the acting rector. Management processes and decision-making will continue as normal under the leadership of the acting rector together with the Executive Committee of the Executive Management (Exco) and the Executive Management. This applies to the decision about the future of the Reitz Residence as well as the continuing implementation of the policy on diversity in student residences.

According to Judge Hancke it was important that Prof. Fourie took sabbatical leave in the light of the long period he has been at the forefront of very demanding changes. There are many challenges that still lie ahead.

During his leave Prof. Fourie will be involved with the Higher Education South Africa (HESA) investigation into diversity and racism on campuses, with research and a national conference on institutional culture, as well as the Association of Commonwealth Universities (ACU) benchmarking project and its conference in Australia at the end of August 2008.
