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.).”

Higher education institutions such as universities need information and accurate data to make critically important management decisions. Prof Francis Petersen, Rector and Vice-Chancellor of the University of the Free State (UFS), expressed these sentiments during his introduction at the 2017 HEMIS Institute recently held in Bloemfontein.

Reporting a critical part of HE practice
The Department of Higher Education and Training (DHET) uses its Higher Education Management Information System (HEMIS) to manage and verify performance data from Higher Education Institutions (HEIs) regarding four crucial datasets, namely students, staff, space, and postdoctoral information and research fellows. HEMIS data is collected for quality control, funding, and planning purposes, in particular for steering the system and for monitoring the sector. This data must then be audited, since it is used for subsidy allocations to HEIs.

“Institutional reporting on aspects of what we do as public universities is a critical part of practice in Higher Education,” said Prof Petersen. He added, “Whether about insourcing statistics, … student accommodation, or transformation and indicators within that domain, it’s really all about accurate data with which informed, evidence-based decisions can be made. This HEMIS Institute 2017 ultimately enables us to share insights across institutions, which can grow and strengthen the sector as a whole.”

which informed decisions can
be made’—Prof Francis Petersen

Public and private HEIs attend training alongside government reps
The Institutional Information Systems Unit of the Directorate for Institutional Research and Academic Planning (DIRAP) hosted and presented the Southern African Association for Institutional Research (SAAIR) HEMIS Foundations workshop and the annual HEMIS Institute in Bloemfontein. These training opportunities were attended by university data managers and representatives from 26 public and private HEIs, as well as representatives from the Council on Higher Education (CHE), DHET, and the Namibian National Council for Higher Education (NCHE). The Foundations workshop was designed to assist those new to the platform to be better acquainted with this data management tool, while the two-day Institute was structured to answer complex questions and address issues around the use of the relevant reporting structures and software.
