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.).”

But do you forgive yourself, Eugene de Kock? asks Candice Mama

Candice Mama and her family met with her father’s assassin. Eugene de Kock. Prime Evil. Commander of the apartheid government’s covert Vlakplaas police unit. And what followed from this meeting was one of our country’s most poignant gestures of reconciliation. One by one, each family member expressed their forgiveness of De Kock, and soon afterwards, he was granted parole.

Candice recently visited the Bloemfontein Campus to talk about ‘An Unexpected Encounter with Eugene de Kock: A Journey of Transformation’. The event was a collaborative effort between the Institute for Reconciliation and Social Justice and Trauma, Forgiveness, and Reconciliation Studies.

“What makes it possible to cross the boundary from loss and pain to bond with the person who hurt you?” Prof Pumla Gobodo-Madikizela, asked Candice. “I had to educate myself about the when, where, and how, to get a context for Eugene de Kock,” she answered. With the encouragement of her mother, Candice became an avid reader from an early age. She devoured information, so that she could build a picture of this man within a specific historical and political context. What also contributed to this moment of reconciliation for her was De Kock humbling himself and taking full responsibility for his actions.

This meeting was not without inner conflict for Candice, though. “Why am I crying for hím?” she asked herself as she listened to him speak. “Why am I laughing?” she chastised herself as De Kock preened shyly for a group photograph with the family. “Is there something wrong with me to connect with him?” She questioned her values and beliefs. But instead of a monster, Candice saw the true essence of a repentant human being.

But how do you know he didn’t fake it, many people asked. Because it was “one of the most sincere and honest encounters I’ve experienced,” she said. During their meeting, Candice saw a man “crushed by the world”. Everything he believed as a young man, he realised, was a lie.

“Do you forgive yourself?” Candice asked the one question De Kock feared most. And in that moment, he was humanised for her. “When you’ve done the things I’ve done,” De Kock replied, “how do you forgive yourself?”
It remains an open question. But this act of forgiveness gives an entire country hope.
