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 Physics Department at the University of the Free State (UFS) not only recently educated the local community about the mystery of dark matter, but shared its knowledge with a much wider audience.

The first screening of two planetarium full-dome films, The Dark Matter Mystery and Dark, at the Naval Hill Planetarium were concluded with a recording for the radio programme Sterre en Planete. During the discussion, led by Hennie Maas from RSG radio station, the audience asked questions that were answered by Prof Matie Hoffman, Associate Professor at the department, Sakkie van der Westhuizen, a PhD student in astrophysics, and Mariette Erwee from the School of Mathematics, Natural Sciences and Technology Education. The radio show was broadcast on 18 June at 19:30 on RSG.

Shows screened at special event
According to Prof Hoffman the planetarium hosts a movie premiere whenever pre-rendered shows are screened for the first time. The films shown on 10 June 2017 introduced viewers to the quest for dark matter. “Dark Matter makes up a huge part of the Universe, but it is a great mystery. We know very little about it. We cannot see it, and it is an area of enormous interest to scientists,” Prof Hoffman said.

Films sourced from European Southern Observatory
The event was attended by various stakeholders such as loyal planetarium patrons, UFS colleagues, and those interested in astronomy. The films were sourced from the European Southern Observatory, an organisation that makes planetarium content available online.

The Dark Matter Mystery took the audience on contemporary astrophysics’ biggest quest. They saw why astronomers know dark matter exists. Dark, directed by Peter Morse, is an adventure that goes to the very edges of contemporary cosmology and data visualisation, telling a complex scientific story with a touch of humanity.

The films will be screened at the Naval Hill Planetarium from time to time and those interested can visit Computicket for more info.
