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 university’s Autumn Graduation Ceremony infused the Bloemfontein Campus with exhilaration last week.

Beaming with pride, graduates received 526 diplomas/certificates and 2 796 bachelor’s and honours degrees in total.

Prof Jonathan Jansen, Vice-Chancellor and Rector, lead each procession of graduates from the Red Square down the path to the Callie Human Centre while the beat of drums filled the air. “To break the cycle of poverty, get an education, get a degree,” Prof Jansen urged graduates during their respective ceremonies. He underscored the fact that, as graduates, they are ten times more likely to get a job, with the odds rising as they continue their postgraduate studies.

Dr Khotso Mohele, Chancellor of the university, advised graduates not to allow life’s obstacles to discourage them. “Take what you have learned over the last three or four years and use that knowledge to reach your goal,” he said. He also emphasised that graduates need to be able to take standpoint against issues.

Graduates’ ceremonies were made even more memorable by various local and international speakers and performers.

American student and tap-dancer, Joshua Johnson, inspired the audience with his story of hope and perseverance. As a student from Penn State University, he travels five hours by bus to New York every weekend where he dances on the subway train to earn money for his tuition fees. Joshua told graduates that, in order to achieve their goals, they have to make the best use of the 24 hours they get to live daily. “Don’t follow in the footsteps of someone else. Take the beat of life, but add your rhythm to it," his wise words resonated with the exhilarated graduates. The audience could not help but clap to the rhythmic beat of his tap-dancing performance.

Vicus Visser, dubbed Bloemfontein’s Justin Bieber was also on the list of performers. Vicus – a South African YouTube singing sensation – performed with his brother, Vincent, to the delight of the crowd.

Radio personality and Idols South Africa judge, Gareth Cliff, was also among the speakers who addressed the graduates during the week. “It’s a good time be alive, a good time to be a South African, a good time to be a qualified South African,” he said. “It’s a time in our country’s development that we require minds such as yours to propel us forward,” was part of his message. Gareth also stressed the freedom of speech in South Africa, especially the freedom of the media.

The Autumn Graduation Ceremony of 2013 was an immense success and filled the hearts of Kovsie graduates, students, staff, parents, family and friends with overwhelming pride.

The Qwaqwa Campus’ graduation ceremony will take place on 8 June 2013. Diplomas / certificates up to and including doctorates will be awarded at this ceremony.
