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.).”

Alumni inspired to keep flying the Kovsie flag high at reunion weekend festivities
2015-09-01

Dr Khotso Mokhele and Adv Roelf Meyer

The University of the Free State hosted alumni from all over the country on the Bloemfontein Campus during a weekend of exciting events, talks, and tours around the campus on 28 and 29 August 2015.

The celebratory events were kick-started with a leadership symposium hosted by Dr Marcus Ingram, Director: Institutional Advancement with Adv Roelf Meyer. The symposium was attended by current student leaders and the SRC Presidents Alumni Association. In his dialogue with the audience, Adv Meyer shared his experiences and personal growth in the process of bringing about democracy in the country with student leaders as change agents. “If you really want to contribute to change, it is not only an intellectual exercise; it is also a heart and soul thing,” he said.

The anchor event was the inaugural Chancellor’s Distinguished Alumnus Award Luncheon hosted by Chancellor, Dr Khotso Mokhele. Prof Jonathan Jansen, Vice-Chancellor and Rector, welcomed guests by highlighting the latest extraordinary achievements of UFS students and academic staff.

Keynote speaker of the day, Ms Nozizwe Madlala-Routledge, Executive Director of Inyathelo and a renowned politician, spoke of the role that universities have in preparing women for leadership roles and how they, in turn, can prepare society for female leadership.  She commended the UFS’s advancement efforts supported by the Kresge Foundation, which supports young people, to keep them in universities. “I am proud to say that the UFS’s efforts in advancement have achieved its goals.”

In his remarks, Dr Mokhele said “what draws a student back to his/her Alma Mater is the quality of the experience they had on campus.  This campus contributed to the transformation of this country through alumni such as Roelf Meyer and Kobie Coetsee.”  He said this initiative should create a lived experience for students on the university campus.  The Chancellor presented the Distinguished Alumnus Award to Adv Roelf Meyer, for his outstanding contributions to the human interests of South Africa, and his current work of facilitating peace processes around the world.

In accepting the award, Adv Meyer introduced Youth Zones, a project which he has been involved with for the past five years, empowering and supporting 40,000 youths in the Free State. In accepting the award, he said “I was a first-year student in 1960, my year group represented the most emphatic group of this university. There are many who came before and after us who well deserve this award, therefore, I accept it on behalf of all alumni.”

To wrap up the weekend’s festivities, former SRC President, Richard Chemaly, hosted the Faculty of Law alumni cocktail event at the CR Swart Auditorium.
Speaking at the event, Prof Caroline Nicholson, Dean of the Faculty of Law, said “A faculty cannot exist without its alumni, we need you to carry us.  Your continued support and collaboration is truly appreciated.”

Alumni and staff enjoyed further entertainment by well-known musical groups, Freshly-Ground and The Muses.
