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.).”

During the recent announcement of the Corobrik Architecture Student of the Year, Lana Bramley was named regional winner in the Free State. Bramley is currently a master’s degree student in the Department of Architecture at the University of the Free State (UFS).

For her dissertation, she examined the design of an art gallery as a liminal architectural intervention, questioning the rigid boundaries of the UFS Campus. Bramley obtained distinctions for her Architecture dissertation, Design dissertation, and for Construction.

Bramley will join Roodt Architects next year.

The following students were also named winners in this year’s regional competition:

  • Best use of brick in a design: Nina Nel
  • Second place in the Corobrik Architectural student of the year competition (regional): Petru du Toit
  • Third place in the Corobrik Architectural student of the year competition (regional): Sinjon Moffett

From the master’s class, a total of 27 students obtained distinctions (nine for Design dissertation, 12 for Construction and six for Architecture dissertation). Prof Jan Smit and Henry Pretorius, Head of the Department of Architecture, awarded two prizes respectively to the best Technical Design student, Janrie Haarhoff, and the best Architecture dissertation student, Petru du Toit.

Musa Shangase, Commercial Director of Corobrik, congratulated students on the quality of their work. It is the 30th year this competition has been presented by Corobrik, a company that is 114 years old, to encourage talent in this profession. The national winner is expected to be announced in May 2017.
