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.).”

When entrepreneurship meets industrial innovation

Internationally acclaimed Argicon Pelleting is a worldwide supplier of pelleting machinery and equipment as well as agri-processing factories. The company was established in 1993 by André and Johan Eksteen, UFS 2004 MBA graduate. After taking over sole ownership, the company grew from a one-man business to an internationally respected specialist in the design and manufacturing of pelleting solutions for the agricultural industry.

A common practice in industrial procedures, pelleting involves processing material into small dry pellets. This is used globally by manufacturers of animal feed or recycling facilities that specialise in processing materials for reuse. This process, however, can only be successfully accomplished with specialised equipment, namely a pelletizer. With fifteen years’ experience in agriculture, and international exposure in countries such as Uganda, Australia, Singapore and New Caledonia, this was not a tall order for Johan.

Agricon focuses on consistently developing innovative ways to add value to its offering. The business has successfully installed pelleting equipment for a range of products, including tobacco dust, rooibos tea, human sludge waste, organic fertilizers and vermi-compost. In addition to the manufacturing of machines and equipment, the company also provides training and on-site installation for clients, as well as support following a sale or the provision of spare parts. The company also provides advice on new product developments and business opportunities for clients within the sector.

Apart from doubling its sales between 2013 and 2014, the company gained great recognition within the industry. Johan was awarded the University of the Free State Business School’s Entrepreneur award in 2013 and he is the first-prize winner of the ILO Free State EnterPRIZE Job Creation Challenge for 2014. He is currently one of 15 finalists countrywide in the Entrepreneur of the Year competition sponsored by Business Partners and Sanlam. Johan is the mentor and stand-in manager for Almenta, a skills development company (winner of the ILO Best Social Entrepreneur for Skills Development award) and Equus Groom School (winner of the ILO Social Entrepreneur in Youth Development award).

Johan was also announced as the winner of the SA entrepreneur of the year for small businesses.
