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.).”

To be an ambassador for the University of the Free State (UFS) is a goal of the Odeion String Quartet (OSQ) and that is exactly what it will do through international visits to Tanzania and Austria. The OSQ, the only residential university quartet in South Africa, will play concerts abroad, share knowledge and build relationships.

It visits Dar es Salaam, Tanzania, from 17 to 20 November 2016 and Austria from 29 November to 4 December 2016. The quartet, which constitutes string lecturers at the Odeion School of Music, consists of Samson Diamond, Sharon de Kock, Jeanne-Louise Moolman and Prof Anmari van der Westhuizen Joubert.

A humbling experience
The OSQ was invited by Hekima Raymond, founder and conductor of the Dar Choral Society, to Tanzania to assist the symphony orchestra. Raymond is a self-taught pianist and conductor and was nominated for a BBC Outlook Inspirations award in 2016.

The quartet will lead the string sections of the orchestra, consisting of members from Uganda, Kenya and Tanzania, performing Beethoven’s fifth symphony and Verdi’s Requiem.

According to Diamond it is a humbling experience, an opportunity to extend their services and help establish the Dar Choral Society. “You are part of something really special, because the circumstances are remote if you compare it to what we have here.”

He means it is important to have a real African footprint and being involved there can later serve as a platform for UFS recruitment.

“You are part of something really special,
because the circumstances are remote if
you compare it to what we have here.”

South African and Austrian collaboration
According to Prof Van der Westhuizen Joubert it is an honour to play in Austria, as Europe is a centre for classical music. The OSQ will play concerts at the Alte Schmiede, Vienna, and the University of Salzburg.

The concert on 4 December 2016 at the University of Salzburg’s Mozarteum is a highlight because the UFS will have the opportunity to build relationships with the famous music school.

Prof Van der Westhuizen Joubert said it would be a South African/Austrian collaboration. “We will bring them South African works (Mokale Koapeng, AJ Feder, Arnold van Wyk and Peter-Louis van Dijk) and will be playing Austrian contemporary string quartets.”
