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.).”

Johann swims his way to Olympics

In the past couple of months, Johann van Heerden has been swimming his way to the Paralympic Games, and is still preparing as if he will be going to Rio de Janeiro.

The Kovsie swimmer, who will know whether he has been included in the Paralympic team in July 2016, feels his training is progressing well. The Olympics will be held in Brazil from 7 to 18 September 2016. If all goes well, this could be the first of several Olympics for the 20-year-old second-year Education student from the University of the Free State (UFS).

Dream year for Education student

Van Heerden (cerebral palsy), whose hero is the former Paralympic superstar Natalie du Toit, has had huge successes in the run-up to the 2016 Olympics. Among others, he was named the best senior swimmer at the Nedbank National Championships for the Physically Disabled in Bloemfontein in March 2016. At the South African Senior Championships in Durban in April 2016, he qualified for the Olympics in the 100 m breast-stroke with an A-qualifying time, and in the 50 m and 100 m freestyle with B-qualifying times.

Only three male swimmers to Olympics

However, he has to wait until the announcement of the South African Paralympic team, since only three male and three female swimmers will be selected. He will not be competing in another major event before the Olympics. “My short-term goal is to compete in this year’s Games, and, in the long term, I would like to reach even greater heights at the 2020 Games,” he said. Du Toit is an inspiration to him because “she was hard-working, and she had a lot of drive”.

Other students from CUADS also excel

At the above-mentioned National Championships, Van Heerden won a total of five gold medals (200 m medley, 100 m breaststroke, 50 m freestyle, 50 m breaststroke, and 200 m breaststroke) and one silver medal (100 m freestyle). Other students from the Center for Universal Access and Disability Support at the UFS also excelled.

Dineo Mokhosoa (cerebral palsy) won three gold medals (long jump, shot-put, and discus), while the athlete Louzanne Coetzee (blind) shattered the world record in the 5 000 m, as well as the Africa record in the 1 500 m. Juanré Jenkinson (cerebral palsy) won two silver medals (discus and shot-put) while Danie Breitenbach (blind) won two gold medals (800 m and 1500 m).
