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.).”

UV vestig hom afgelope eeu as leier op verskeie terreine
2004-05-11

Michelle O'Connor - Volksblad - 11 Mei 2004

Ondank terugslae nou 'n 'gesonde volwassene'

HOEWEL die Universiteit van die Vrystaat (UV) vanjaar sy eeufees vier en met 23 000 studente die grootste universiteit in die sentrale deel van die land is, was dié instelling se geboorte glad nie maklik nie. MICHELÉ O'CONNOR het met prof. Frederick Fourie, rektor, oor die nederige begin van dié instelling gesels.

DIE behoefte aan 'n eie universiteit in die Vrystaat het reeds in 1855, kort ná die stigting van Grey-kollege, kop uitgesteek.

Grey se manne het hulleself teen 1890 begin voorberei om die intermediêre B.A.-eksamens af te lê. Dié eksamen het hulle toegang gegee tot die tweede jaar van 'n B.A.-graad aan die destydse University of the Cape Good Hope, nou die Universiteit van Kaapstad.

"Presidente F.W. Reitz en M.T. Steyn het destyds albei die stigting van 'n universiteit hier bepleit. Die grootste rede was sodat die seuns van die Vrystaat nie weggestuur word nie.

"Dié twee se droom is op 28 Januarie 1904 bewaarheid toe ses studente hulle onder dr. Johannes Bril, as hoof/rektor van Grey-kollege, vir die graad B.A. ingeskryf het. Dié graad is aanvanklik deur die Kaapse universiteit toegeken.

"Net die klassieke tale soos Latyns en Grieks, die moderne tale, Nederlands, Duits en Engels, filosofie, geskiedenis, wiskunde, fisika, chemie, plant- en dierkunde is aanvanklik aangebied.

"Die UV se geboue het gegroei van 'n klein tweevertrek-geboutjie wat nou naby Huis Abraham Fischer staan, en verblyf in die Grey-kollege se seunskoshuis," sê Fourie.

Volgens hom is die universiteit se eerste raad en senaat tussen 1904 en 1920 saamgestel. Die eerste dosente is aangestel en die eerste geboue opgerig. "Dié tyd was egter baie moeilik.

"Die instelling het teen 1920 net 100 studente gehad en was geldelik in die knyp. Daar was geen vaste rektor nie en geen vooruitgang nie. Vrystaatse kinders is steeds na ander universiteite gestuur.

"Ds. J.D. Kestell, rektor van 1920 tot 1927, het egter dié instelling finaal gevestig.

"Hy het self studente van oor die hele Vrystaat gewerf en geld by onder meer kerke en banke ingesamel. Kestell het selfs Engelse ouers oortuig om hul kinders na die Greyuniversiteitskollege (GUK) te stuur en teen 1927 het dié instelling met 400 studente gespog.

"In die tydperk tussen 1927 en 1950 het die GUK weer verskeie terugslae beleef.

"In dié tyd was dit onder meer die Groot Depressie en die Tweede Wêreldoorlog. Die armblanke-vraagstuk het regstreeks op studente en dosente ingewerk en die politieke onderstrominge van dié tyd het die instelling ontwrig.

"Die GUK het egter oorleef en die Universiteitskollege van die Oranje-Vrystaat (UKOVS) is in 1935 gebore," sê Fourie.

Hy sê in dié tyd is verskeie fakulteite gevestig en teen 1950 het die UKOVS met 1 000 studente gespog.

Teen 1950 het dit 'n onafhanklike universiteit geword en die naam is verander na die Universiteit van die OranjeVrystaat (UOVS).

Dié tydperk is gekenmerk deur Afrikaner- en blanke selfvertroue en heerskappy. Studentegetalle het tot 7 000 in 1975 gegroei en heelwat vooruitgang het in dié tyd plaasgevind.

"Tussen 1976 en 1989 sukkel dieuniversiteit weer met onder meer ekonomiese krisisse, die land se politieke onstabiliteit en word die UOVS geï soleer.

"Een ligpunt in dié tyd is die toelating van die eerste swart studente, die nuwe Sasol-biblioteek en die fakulteit teologie wat die lig sien.

"Tussen 1990 en vanjaar het die UOVS verskeie op- en afdraandes beleef. Die universiteit doen nie net die eerste stappe van transformasie nie, maar begin ook aan 'n beleid van multikulturaliteit werk.

"Die UOVS se naam verander in 1996 na die Universiteit van die Vrystaat/University of the Free State en in 2001 word die Sotho-vertaling bygevoeg.

"Geldelike druk en probleme neem drasties toe en personeel word gerasionaliseer.

"Teen 2000 begin die UV met 'n draaistrategie en studentegetalle neem tot meer as 23 000 toe," sê Fourie.

Hy sê die UV het die afgelope eeu nie net verskeie terugslae oorleef nie, maar homself ook op verskeie gebiede as 'n leier gevestig.

Die universiteit behaal sy eie geldelike mikpunte, neem 'n nuwe taalbeleid van veeltaligheid aan en herbelê in personeel.

Die instelling inkorporeer die kampusse van die Vista- en Qwaqwa-universiteit en groei internasionaal.

Die UV vestig ook fondamente van 'n institusionele kultuur van verdraagsaamheid, geregtigheid en diversiteit.

"Die baba het in die afgelope eeu 'n gesonde volwassene geword."
