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.).”

Academic delivers inaugural lecture on South African foreign policy
2007-08-06

 

In her inaugural lecture Prof. Heidi Hudson from the Department of Political Sciences, focused on the impact that Pan-Africanist sentiments have had on South Africa’s foreign policy. She also put the resulting contradictions and ambiguities into context. At her inaugural lecture were, from the left: Proff. Frederick Fourie (Rector and Vice-Chancellor of the UFS), Heidi Hudson, Engela Pretorius (Vice-Dean: Faculty of The Humanities) and Daan Wessels (Research Associate in the Department of Political Science).

Academic delivers inaugural lecture on South African foreign policy

“We are committed to full participation as an equal partner … opposed to any efforts which might seek to project South Africa as some kind of superpower on our continent. … the people of Africa share a common destiny and must therefore … address their challenges … as a united force...” (Mbeki 1998:198-199).

Prof. Heidi Hudson from the Department of Political Science referred to this statement made by president Mbeki (made at the opening of the OAU Conference of Ministers of Information in 1995) when she delivered her inaugural lecture on the topic: South African foreign policy: The politics of Pan-Africanism and pragmatism.

One of the questions she asked is: “Can the South African state deliver democracy and welfare at home while simultaneously creating a stable, rules-based African community?”

She answers: “South Africa needs to reflect more critically and honestly on the dualism inherent in its ideological assumptions regarding relations with Africa. South Africa will always be expected by some to play a leadership role in Africa. At the moment, South Africa’s desire to be liked is hampering its role as leader of the continent.”

In her lecture she highlighted the ideological underpinnings and manifestations of South Africa’s foreign policy. Throughout she alluded to the risks associated with single-mindedly following an ideologically driven foreign policy. She emphasised that domestic or national interests are the victims in this process.

Prof. Hudson offers three broad options for South Africa to consider:

  • The Predator – the selfish bully promoting South African economic interest.
  • Mr Nice Guy – the non-hegemonic partner of the African boys club, multilaterally pursuing a pivotal but not dominant role.
  • The Hegemon - South Africa driving regional integration according to its values and favouring some African countries over others, and with checks and balances by civil society.

She chooses option three of hegemony. “Politically correct research views hegemony as bad and partnership as good. This is a romanticised notion – the two are not mutually exclusive,” she said.

However, she states that there have to be prerequisites to control the exercise of power. “The promotion of a counter-hegemon, such as Nigeria, is necessary. Nigeria has been more effective in some respects than South Africa in establishing its leadership, particularly in West Africa. Also needed is that government should be checked by civil society to avoid it sinking into authoritarianism. The case of business and labour coming to an agreement over the HIV/Aids issue is a positive example which illustrates that government cannot ignore civil society. But much more needs to be done in this regard. South Africa must also be very careful in how it uses its aid and should focus potential aid and development projects more explicitly in terms of promoting political stability,” she said.

Prof. Hudson said: “It is also questionable whether Mbeki’s Afro-centrism has in fact promoted the interests of ordinary citizens across Africa. Instead, elite interests in some countries have benefited. But ultimately, the single most important cost is the damage done to the moral code and ethical principles on which the South African Constitution and democracy is founded.

“In the end we all lose out. More pragmatism and less ideology in our relations within Africa may just be what are needed,” she said.
