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.).”

Inaugural lecture challenges leaders in higher education

Lecture
(Pdf format)

According to international statistics, South Africa’s school performance is rated 140th out of 144 countries. South Africa is also ranked 143rd out of 144 countries when it comes to  the quality of mathematics and science. About 600 000 South African graduates are unemployed and about 500 000 learners are failed by our current education system.

Dr Mamphela Ramphele brought these shocking statistics to the light at the inaugural lecture of the Annual Prestige Lecture at the Faculty of Education on Thursday 25 October 2012 at the University of the Free State (UFS).

This lecture will henceforth be known as the Mamphela Ramphele Prestige Lecture.

Dr Ramphelefocused her lecture on ‘Educating the 21st century citizen’.

“One of the defining characteristics of the 21st century is the vast number of choices that confront us every day at a personal, professional and political level.”

She asked if 21st century South Africans are equipped with the skills to make the choices that confront them daily.

“The failure to transform our apartheid education into one characterized by equity and excellence, is producing graduates who lack self-confidence.”

Dr Ramphele said that in South Africa about 1/6th of government expenditure goes to education, but the outcomes remain shocking.

For Dr Ramphele the answer lies in creating platforms for open conversation about South Africa’s painful past and the agenda for radical socio-economic restructuring should include the fundamental transformation of education.

She praised the UFS, under its current inspirational leadership, for its role as change agents through the education.

Prof. Rita Niemann, senior professor at the Faculty said the Annual Mamphela Ramphele lecture is to further expand and celebrate education in South Africa.

“Dr Ramphela has given us so much food for thought by challenging leaders in higher education to speak out about the questionable state of education in South Africa and to become engaged in the ‘revolution of the spirit’ in order to deliver citizens who own and shape the country.”
