Improving front-line triage in Yemen

We supported the development of One Shot Immersive's BIMA award-winning VR training experience, used to improve mass casualty triage in austere and high threat environments.

This technology prepares people to respond to mass casualty events such as natural disasters and terror attacks. It is now being delivered in Yemen by the David Nott Foundation, with other countries including Somalia planned.

The challenge
  • Uncover unserved user needs to inform the next iterative development phase.

  • Establish measures and a data baseline to understand the effectiveness of the training experience.

  • Ensure the headset experience is accessible and easy to use in challenging environments.

  • Audit the existing experience. 

  • Commission a survey on the experience and its effectiveness.

  • Capture data using the baseline to dictate next steps.

Next-gen medical training

One Shot Immersive develops VR training experiences to improve medical and situational awareness. They have successfully delivered educational workshops on humanitarian disasters and warfare through their partnership with the David Nott Foundation, saving countless lives in the process.

Auditing experiences to save lives

We validated the training experience to provide essential support to medics on the frontline of the world’s most turbulent areas. This is to support local hospitals and safeguard resources in Yemen where there are four surgeons for every million people.

To provide validation, we first performed a comprehensive experience audit to form recommendations used to improve product features, functionality and the user journey. This ensures the product is intuitive and meets the needs of both medical trainers and trainees.

It's great to see VR training and triage for the developing world. Its potential impact is untold and inspiration to use VR for practical purposes.

Assessing the experience with frontline personnel

In phase two, we interviewed doctors across sites, to measure the engagement and confidence levels of users. Initially, the testing focussed on headset configuration and messaging. We asked questions such as - were the instructions clear and easy to follow, without having to troubleshoot?

We then assessed the headset’s VR environment which offers a lifelike experience based on a live warzone. One user consideration, taking the graphic content into account, was motion sickness and discomfort. Another centred around learning and whether the content delivered on that front.

We tasked participants to distil their learnings, touching on the retention of information and documenting their psychological response to the headset and content experience. In time, this data will inform an expert review.

This will provide One Shot Immersive with the means to measure the effectiveness of the headset and make iterative improvements over time.

Foolproof are global leaders. To have them as part of the product design team, taking VR to the world's worst humanitarian crisis, was something I am truly grateful for. VR trauma training has the power to save so many lives, but product design is critical. Foolproof helped us identify ways of immersing the user more fully, allowing them to experience the chaos of a mass casualty in a safe and engaging way. I want to thank everyone at Foolproof, their skills can add huge value to the humanitarian sphere.

Yemen and beyond

One Shot have delivered training workshops to doctors/medical personnel, in both Yemen and Syria. This is just the start of a global initiative which is quickly gaining international traction with the experience heading to Somali for further testing and development in the near future.
