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.).”

New building on UFS Qwaqwa Campus makes provision for research on environmental problems
2015-12-11

The new Geography and Physics Building on the Qwaqwa Campus

Student numbers in Geography and Physics on the Qwaqwa Campus of the University of the Free State have escalated over the past five years. This has resulted in a need for more space for these two departments.

The acute and persistent shortage of lecturing space has been a major stumbling block on the campus, with only four of the Natural Sciences departments - Chemistry, Physics, Plant Sciences, and Zoology and Entomology – able to fit into the Natural Sciences building. To solve the problem, a separate facility for both the Geography and the Physics departments was built.

The new complex, which includes lecture rooms, laboratories, and offices, places the Department of Physics on the ground floor because the weight of some of the laboratory equipment. The Department of Geography is on the first floor.

The Department of Geography places strong emphasis on montane research. Research is being conducted on environmental problems in the Maluti-a-Phofung area. This research encompass in situ and ex situ conservation of paleontological resources, with the aim of setting up a GIS-based environmental management system, as well as the role of local cultures in promoting regional tourism.

The Department of Physics places emphasis on changing and improving community perceptions of electricity and electronics. The major part of the research has been in the field of solid-state physics, and, more specifically, on nanophosphors and other luminescent nanoparticles.

The building is in the north-eastern corner of the campus, opposite the Faculty of Natural and Agricultural Sciences.

The project was completed in 2015.
