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.).”

With murder and robbery rates on the rise, the Forensic Science Programme of the Department of Genetics at the University of the Free State is playing a key role in training South Africa’s future crime scene investigators and forensic laboratory analysts.

According to the Institute for Security Studies (ISS), murder and aggravated robbery rates for 2014/2015, as recorded by the South African Police Services (SAPS) have increased. Incidents of murder increased by 4.6% in the period from 2013/2014 to 2014/2015 and aggravated robbery increased by 8.5 % in the same period. The ISS is an African organisation thant enhances human security by providing independent and authoritative research, expert policy advice and capacity building.

Dr Ellen Mwenesongole, a forensic science lecturer at the Department of Genetics, said the university was one of a few universities in South Africa that actually had a forensic science programme, especially starting from undergraduate level.

Crime scene evaluation component incorporated in curriculum
As part of its Forensic Science Honours Programme, the department has, for the first time, incorporated a mock crime scene evaluation component in its curriculum. Students process a mock crime scene and are assessed based on how closely they follow standard operating procedures related to crime scenes and subsequent laboratory analysis of items of possible evidential value.

The mock crime scene forms part of a research project data collection of the honours students. In these projects students utilise different analytical methods to analyse and distinguish between different types of evidence such as hair fibres, cigarette butts, illicit drugs and dyes extracted from questioned documents and lipsticks.

This year, the department trained the first group of nine students in the Forensic Science Honours Programme. Dr Mwenesongole, who received her training in the UK at the University of Strathclyde in Glasgow, Scotland, and Anglia Ruskin University in Cambridge, England, said incorporating a crime scene evaluation component into the curriculum was a global trend at universities that were offering forensic science programmes.

Department of Genetics and SAPS collaborate
It is important to add this component to the student’s curriculum. In this way the university is equipping students not only with theoretical knowledge but practical knowledge on the importance of following proper protocol when collecting evidence at crime scenes and analysing it in the laboratory to reduce the risk of it becoming inadmissible in a court of law.

The Genetics Department has a good working relationship with the Forensic Science Laboratory and Free State Crime Scene Management of the Division Forensic Services of the SAPS. The mock crime scene was set up and assessed in collaboration with the Crime Scene Management Division of the SAPS. Although the SAPS provides specialist advanced training to its staff members, the university hopes to improve employability for students through such programmes.
