Virtual dog new tricks: virtual reality game a creative tool to help manage acute pain

A virtual reality game featuring a dog offers a non-pharmacological complement to opioid interventions in acute pain management.
A virtual reality (VR) game featuring a little dog and a simple quest offers a non-pharmacological alternative to acute pain management.
The immersive game, calledFinding Home, builds rapport between the user and dog, developing patient resilience and coping skills. As such, it presents a compelling distraction to help reduce high dose opiates.
This character-driven approach is an innovative take on VR use for pain management, says Director of theat UNSW Sydney,Scientia Associate Professor John McGhee, a lead researcher on the project.
By introducing a canine character as a companion in its quest, the game provokes stronger attachments with its users, the Director of the 3D Visualisation Aesthetics Lab at UNSW Sydney says.
Its about building connection with character. We designed this little dog its super cute and youre in this very abstract landscape and youve got to take the dog home.
Youre investing in the [dogs] character, rather than just investing in yourself which moves you away from the internalisation of pain.
The project is a collaboration between UNSW and St Vincents Hospital Pain Medicine Department, Sydney, and is funded by the and Samsung. Samsung have also donated VR headsets for the randomised control clinical trial. The prototype is currently being tested through the Acute Pain Service at St Vincents Hospital, Sydney.
The project moves to explore alternatives to acute pain relief to complement opioid intervention and, in so doing, to minimise the risk of chronic pain, says Professor Steven Faux, Director of the Department of Pain Medicine at St Vincent's, Sydney.
Reliance on medication alone makes people feel passive in their pain management. By contrast studies engaging with virtual reality have shown that it can decrease anxiety and distress, thereby helping to control pain levels.
Sometimes, you just feel stressed and uncomfortable, and the only thing you can do is take an opiate, which is not always the right thing to do. A/Prof. McGhee and I have worked on technologies to give them an alternative.

A quest beyond pains walls
The VR game has been codesigned by computer animation artists, virtual reality/gaming designers, psychologists and pain specialists. Users navigate an imagined landscape trying to help the dog find its way home.
To practice the controls, you throw sticks and the dog has to bring them back. Then you do a number of activities with the dog, building a bridge, finding a rainforest. You have to find the parrots in the trees. Its very Australian, A/Prof. McGhee says.
Using research and published evidence to guide the design of the program was also a key focus of the team. There have been lots of lessons learned in past research about the types of imagery, visual and audio stimulation that can help people experiencing pain, saysDr Christine Shiner, a senior researcher on the project from St Vincents, Sydney. This research helped inform the design of the program, to make it more than just a game.
Priming the palette
The game uses cool hues notably blues and purples to placate patients pain response.
Weve developed the environment to keep the patient feeling cool so we avoided reds, and really intense colours it doesnt look like a real place thats informed by the psychology of aesthetics, A/Prof. McGhee says.
[Its about] trying to cool them down, moving away from that red-hot white pain feeling towards a cool self-soothing environment.
The aesthetic is cartoon in style to maximise the capabilities of the equipment and to minimise the threat of the unfamiliar, A/Prof. McGhee says. Its a portable headset so it has some limitations so we had to be smart with the design.
Additionally it had to accommodate patients being bed bound, engaging purely through head movements, he says. We had to make the interface conducive to that very restrictive movement while still feeling immersive and interactive.
The spaces, the palette and the interactions are all informed by research to create a positive, healing environment. All these little microtransactions and interactions, theyre all there to make you feel safe. And in doing so, it takes your attention away from simply pressing the opioid button, he says.

Teach a virtual dog
Ultimately the team aims to build artificial intelligence into the dog, and introduce additional levels to the game, if the initial trials are successful, A/Prof. McGhee says.
You could build resilience into the dog so the more you play, the better the dog copes and gets on with things like a Tamagotchi, [the handheld Japanese digital pet], you keep coming back to it.
We wanted the game to have this kind of stickiness to it so it wasnt just a one-hit wonder, he says.
Prof. Steven Faux says: Our initial results with the prototype have been very positive. If the trial shows marginal improvements, its a win-win. As a non-pharmacological intervention, the game has multiple advantages: the less reliant on medication the patient is, the better the long-term outcomes.
Harnessing the power of storytelling
The game exemplifies how creative skills such as visualisation and animation can be re-tasked to directly impact health outcomes and quality of care in clinical settings, A/Prof. McGhee says.
A lot of it boils down to story, whether its immersive, interactive or a linear animation. Storytelling provides a powerful tool for better informing patients, and the general public more broadly, about treatment and the nature of disease and other health messages.
A/Prof. McGhees previous research collaborations have included immersive platforms that simulate scientific phenomena, such asto help patients understand their treatment (again with St Vincents), ,and educational 3D animations demonstrating the.
He received the inauguralDistinguished Research Award for his work with the and was nominated for the. He also recently participated on a panel at the internationally renowned that celebrates innovation for social change.
VR for good
The 3D Visualisation Aesthetics Lab (the Lab) harnesses creative practice, technical innovation and immersive platforms to create world-class data visualisations. Their research contributes to virtual world design, scientific discovery, education and engagement, biomedical communication and clinical interaction.
The Labs visual approach to designing content is what sets them apart from more technical labs, including industry heavyweights in Silicon Valley more focused on delivering new hardware and tools, he says.
Our production on the activity of soap on the COVID-19 virus, for example, the quality of the output was world-class. It was recognised by prestigious animation festival SIGGRAPH Asia. For a small highly effective animation lab to get a foothold there says something.
If the trials of the VR gaming prototype deliver on their promise, the platform has commercial potential.
If we get this right if we can show evidence that it works we could license it to other hospitals, distribute it more broadly, he says.
