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.).”

One of six – and the only contender from outside the United States of America. This is the extent of the achievement by the Odeion School of Music Camerata (OSMC) – one of six finalists in the 2017 International Ictus Music Competition.
The OSMC at the University of the Free State reached the final round of the competition, of which the winners will be announced on 1 September 2017. The competition is an innovative new online competition for ensembles, orchestras, and band/wind ensembles (middle school, high school, youth ensemble, community ensemble, and college/conservatory/university) that compete through video submission.

Odeion concert recorded as entry
The OSMC celebrated its fifth birthday on 31 May 2017, hosting a concert as part of the first round of the competition in the Odeion on the Bloemfontein Campus. The concert, which also served as a fundraising opportunity, consisted of a carefully curated concert programme which was recorded and submitted to the Ictus panel.

The repertoire for the concert, supported by a Concerts SA grant from the Samro Music Foundation, was commissioned from South African composers. Maestri Xavier Cloete and Gerhard de Jager served as conductors.

Substantial money prizes can be won, and ensembles will receive written feedback from a jury consisting of renowned maestri including Stilian Kirov, who was awarded 1st Prize in the Debut Berlin Competition on 18 May 2017. Top prize-winners will be interviewed and interviews will be broadcasted internationally.


Five years of many highlights

The OSMC was strategically founded in 2012 by Marius Coetzee as the OSM’s flagship chamber ensemble, with the main objective of creating a catalyst for excellence.

Over the past five years, the OSMC has premiered 15 new works by South African composers specially commissioned for them. A highlight remains its participation in the 13th International Conservatory Festival in St Petersburg Russia, where the ensemble received a standing ovation during a gala concert in the Glazunov Concert Hall.
