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 annual Chancellor’s Distinguished Alumni Awards ceremony was presented by the Office of Institutional Advancement on 5 November 2016, at the University of the Free State (UFS) Bloemfontein Campus. The prestigious awards recognise outstanding achievements of UFS alumni provincially, nationally and internationally. These are alumni who have not only placed the university on the world stage but have inspired the next generation of Kovsies and their communities at large.

“I am proud of this year’s award recipients and it is an honour to recognise them for the contributions they make,” said Justice Ian van der Merwe, Chairperson of the UFS Council, at the ceremony. “With these awards, the university wants to strengthen its bond and replenish its connection with alumni, showcase their achievements, and inspire other alumni and students to achieve in their respective fields,” Justice van der Merwe said.

For the first time, the Young Alumnus of the Year Award was presented, to recognise and celebrate the achievements of alumni who have graduated within the past decade. The recipient of the award, Tanya Calitz, Research Lawyer at the Constitutional Court of South Africa, said in her acceptance speech: “At Kovsies you arrive as a student and leave as a critical thinker and leader.”

The Chancellor’s Distinguished Alumnus Award was presented to Justice Mahube Molemela, Chancellor of the Central University of Technology and Judge President of the Free State High Court. “I accept this award with humility and appreciation from this esteemed institution. It is moments like these that we as alumni should reflect on what we can do to contribute to the excellence of the UFS,” said Justice Molemela.

More awards were presented to alumni in the following categories:
•    Rolene Strauss, former Miss World and student at the UFS.
•    Wayde van Niekerk, current world record holder, world champion and Olympic champion in the 400 metres, and student at the UFS.

Cum Laude Award:
•    Neil Powell, Coach of Blitzbokke that won the bronze medal at the Olympic Games in 2016.
•    Professor Eunice Seekoe, Acting Dean: Faculty of Health Sciences, and leader in Health Science professional training.
•    Gary Stroebel, CEO of Central Media Group and visionary media pioneer.

Executive Management Award:
•    Anna Botha (Tannie Ans), coach and mentor of Wayde van Niekerk.
•    Anton Esterhuyse, musical director, composer, arranger, producer, and performer.
