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.).”

PhD students’ voices reverberate across Africa and beyond

The Centre of Africa Studies (CAS) has been recruiting the best young scholars from across the SADC region – with magnificent success. In the span of six months, four PhD students have excelled both on the African continent and abroad.

Anusa Daimon, Noel Ndumeya, Ivo Mhike and Tinashe Nyamunda – the names of these distinguished students. Set against the backdrop of global excellence and competition, they have been awarded several positions at conferences and already published world-wide.

Anusa Daimon’s PhD studies at the CAS focuses on Malawian migrants and their descendants in Southern Africa. It explores issues of identity construction and agency among this group.

Since his arrival at the CAS, Daimon has won two fully-funded awards to attend international conferences and workshops. He was invited to attend the Young African Scholars Conference at Cambridge University in the UK. He also went to Brazil to the IGK Work and Human Lifecycle in Global History Summer Academy. This workshop explored the historical and modern meanings and practices of work in terms of ‘freedom’ and ‘unfreedom’.

Noel Ndumeya holds a special interest in environmental history and the aspects of conservation and conflict. His PhD hones in on land and agrarian studies with specific focus on South Eastern Zimbabwe.

Ndumeya has won an award from the African Studies Association United Kingdom (ASAUK). This earned him an invitation to Nairobi, Kenya, to work with an editor from the Journal of Southern Africa Studies (JSAS).

Ivo Mhike’s research specialises in youth culture and their relationship with the state. In his PhD he uses juvenile delinquency as a window towards an analysis of social constructs of youth behaviour. This includes youth policy and their institutional and administrative links to the state.

Mhike has been invited to attend the CODESRIA Child and Youth Institute in Dakar, Senegal, with the theme: Social Protection and the Citizen Rights of Vulnerable Children in Africa.

Tinashe Nyamunda specialises in African Economic History. His PhD thesis is entitled, “The State and Finance in Rhodesia: A study of the evolution of the monetary system during the Unilateral Declaration of Independence (UDI), 1965–1979”.

Under the direction of his primary supervisor, Prof Ian Phimister and his secondary supervisor, Dr Andrew Cohen, four of his papers have been accepted for publication. Nyamunda also received sponsorship from the Rector’s Office for an edited book collection of which he is the leading author. The book focuses on the many aspects of Zimbabwe’s blood diamonds.

Recently, Nyamunda has contributed papers at conferences in Botswana and Scotland and attended a workshop at Lund University in Sweden. He has also received an invitation from Germany and Oxford to present some chapters of his PhD thesis.

“The centre has provided the best working environment any PhD student can dream of,” Nyamunda said. He continued to remark that the opportunities Prof Jonathan Jansen has created opened up immense possibilities for them.

“Given these fruitful experiences in just a year at the university,” Nyamunda said,” imagine what can be accomplished given the resources and environment availed by the institution.” The prospects after his PhD studies looks bright, he concluded, because of the opportunities provided by the UFS.
