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 Council votes on top appointments
2003-11-24

The Council of the University of the Free State (UFS) today voted on the filling of four senior vacancies, including three posts at Vice-Rector level and one at the level of Dean.

The Council voted as follows:
- Prof Magda Fourie will be offered the post of Vice-Rector: Academic Planning
- Dr Ezekiel Moraka will be offered the post of Vice-Rector: Student Affairs
- Prof Teuns Verschoor will be offered the post of Vice-Rector: Academic Operations
- Prof Letticia Moja will be offered the post of Dean: Faculty of Health Sciences

Two of the candidates, Prof Teuns Verschoor and Prof Magda Fourie, are currently acting Vice-Rectors at the UFS. Prof Verschoor is acting Vice-Rector for Student Affairs and Prof Fourie is acting Vice-Rector for Academic Planning. Dr Moraka is currently Dean of Student Affairs at the University of Pretoria (UP). Prof Moja is currently the acting Dean of the Faculty of Health Sciences at the UFS.

According to the Rector and Vice-Chancellor of the UFS, Prof Frederick Fourie, the filling of these senior vacancies comes after one of the most thorough search and selection processes ever at the UFS.

“It is wonderful that we are able to celebrate the outcome of this process that has brought forward such excellent candidates who reflect our country’s diversity. It shows that we can achieve the goals of quality and diversity at the same time,” Prof Fourie said.

Prof Magda Fourie (49) received her Ph D on Institutional governance of higher education in transition: a South African perspective from the UFS in 1996. She joined the UFS in 1998, later becoming Director of the Centre for Higher Education Studies and Development and Professor in Higher Education Studies. She said in her declaration of intent her aspiration is to contribute to making the UFS the excellent university it foresees in its vision and mission. Academic planning should position the UFS with regard to its core activities strategically as an institution of excellence that will meet the future from a strong basis of academic integrity and credibility.

Dr Moraka (45) received his Ph D in Education Management on Management of change and conflict resolution by student affairs officers at historically white universities in South Africa from the UP in 2002. He is Dean of Students at the UP since 2001. Before that he was Head of Student Support and Student Social Services at the UP for six years. He was also, among others, a lecturer at a college of education and a pastor of the Dutch Reformed Church in Africa. He said in his declaration of intent that diversity can become so greatly emphasised that people can be driven further apart. Focus should be on moulding a student community where everyone can feel at home, a community which lives together and works together without destroying what is unique to each individual.

Prof Verschoor (53) received his LL D in 1980 at the University of Pretoria on The criminal responsibility of psychopaths and similar figures. He was professor in and Head of the Department of Criminal Law and Medical Law at the UFS for 17 years before becoming Dean of Students in 1994. He said in his declaration of intent that he dreams of the realisation of projects that are awaiting the enthusiastic support, bringing together and empowering of persons involved by a Vice-Rector that wants to see the UFS prosper in an era of continuing dynamic development. In this he would like to make a substantial contribution.

Prof Moja (46) received her MB ChB in 1982 from the University of Natal and her M.Med in Obstetrics and Gynecology in 1990 from the Medical University of South Africa (Medunsa). She became a full professor in 2003 at the UFS and has been acting as Dean of the UFS’s Faculty of Health Sciences since February 2003. She said in her declaration of intent that the challenge for her is to manage change with the ultimate aim of both achieving the vision of the UFS and satisfying the needs of the community. Some of the academic challenges include the training of more people from designated groups and rural areas. Careful planning and integration of the curriculum should be done to ensure that all students perform to their best.
