Virtual reality technology addresses cybersickness in nursing students

Kat Walk Mini_web read more — 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.).”

Emma Sadleir talks about social media etiquette

“We have all become celebrities, we have become social figures because of our power to publish information. We have all become brands, and we need to protect our brand. Digital content is sometimes dangerous content,” said Sadleir.

On 11 May 2016, the University of the Free State, in collaboration with the Postgraduate School, hosted, Emma Sadleir, a leading social media expert, in the Equitas Auditorium on the Bloemfontein Campus. She is an admitted advocate, specialising in social media law. Dr Henriette van den Berg, Director of the Postgraduate School, described Sadleir’s presentation as a privilege for all the staff and students who attended.

Sadleir said that there are two important rules that staff and students of an institution should try to follow. The first is not to bring the name of the institution into disrepute; and the second is not to breach the goodwill of the institution or, in other words, not to bite the hand that feeds you.

“The common law, even if there is no policy, is that anything that brings the company into disrepute can lead to disciplinary consequences up to termination,” said Sadleir.

Sadleir focused on hate speech and free speech, stating that free speech is a right that is entrenched in the constitution, but, like every other right, it has limitations. She mentioned Penny Sparrow, Matt Theunissen, Velaphi Khumalo, and Judge Mabel Jansen, all of whom have been lambasted by the public over their racist posts on social media. Sadleir stressed that, even on social media, content has to be within the confines of the law, and people must remember our rights are not absolute. We have a lot of freedoms, but no one cannot disseminate hate speech.

“Would you publish whatever you thinking on a billboard, close to a busy highway with your name, picture and employers details or the institution you studying at? If you have no grounds to justify the comment, do not post it,” warned Sadlier.

According to the South African Bill of Rights, everyone has the right to privacy, but an expectation of privacy has to be enforced. She said people over-document their lives on social media, decreasing your right to privacy drastically. “It is like CCTV footage of your life. It is simple, the more you take care of your privacy, the more you have,” said Sadleir.

Sadleir said it was important for Facebook users to have privacy settings where they can review posts where they are tagged. According to Sadleir, managing your reputation is not only limited to what you post about yourself but also managing what others post about you.

She cited a 2013 case in the Pretoria High Court in which a new wife wrote a scandalous Facebook post about her husband’s ex-wife, tagging the husband in the post. The courts found both the new wife and the husband guilty of defamation.

“If you have been tagged in something but have not been online and seen the content, you are then an innocent disseminator. The moment you are aware of the post you are liable for the content,” said Sadleir.

“It takes 20 years to build a reputation and five minutes to ruin it. If you think about that, you'll do things differently,” Sadleir said, concluding her presentation with the quotation from Warren Buffet.
