FAQ

We have compiled a list of frequently asked questions regarding Virtual Life Support. If you cannot find the information you’re looking for in the FAQ, feel free to submit a support request.

General

The unassisted training scenario in Virtual Life Support takes approximately 10 minutes to complete.

No, VLS has been designed for use without any prior experience with virtual reality. The use of hand tracking means trainees do not have to familiarize themselves with controller layouts, and instead perform actions using the same motions they would in the physical world.

Depending on the platform, some instruction may be required for the trainer to set up devices. We provide detailed guides on how the headsets can be prepared for a seamless experience for the trainees.

Most VR headsets are designed for ages 13 and up, including the Meta Quest 2. We have tested Virtual Life Support with a wide variety of ages and find that most age groups are able to complete the training. An evaluation version is available if you wish to test VLS for a specific group.

Please contact us if you want to evaluate Virtual Life Support.

Please contact us if you want to deploy Virtual Life Support at an event.

Definitely not. Virtual Life Support has been developed for many use cases, one of them being able to train as often as you want, where you want. Which of course implies individual use without supervising.

Note that HMD vendors and/or vendors of a software platform used for deployment of VLS may impose restrictions on unsupervised use.

Yes. Our team has extensive experience designing VR experiences for a wide audience, including those sensitive to motion sickness or simulator sickness.

Virtual Life Support does not contain any artificial motion (a common trigger for motion sickness), and most of the training is performed kneeling down in a stable position. We also ensure the VR headset is able to run at the lowest latency possible to maximize comfort.

No. Virtual Life Support uses hand tracking which means you control VLS with your hands. You may need your controllers to start VLS depending on the deployment platform you use. In particular ArborXR Home does not yet support hand tracking.

Yes. Virtual Life Support uses hand-tracking and tracks both hand so it does not matter which hand you use.

Features

The CPR score is calculated with both frequency and depth as input.

In our algorithm compression depth is more important than compression frequency. A good compression will still receives a 70% score, even if the frequency is outside of the guidelines, but close to target. Depth and rate both close to target are rewarded with a 60% score.

Depth in target (5-7cm) and rate in target (100-120cpm) = 100%
Depth in target (5-7cm) and rate close to target (70-150cpm) = 70%
Depth close to target (3.5cm+) and rate close to target (70-150cpm) = 60%

The final score is calculated as an average of the scores for all individual compressions.

VLS is currently available in English and Dutch. Please contact us if you require another language for your deployment.

Please contact us if you want to integrate Virtual Life Support with a specific LMS.

At the moment you can train only in one environment, an alley in a city. We intend to add other environments in future versions. If you have a requirements for a specific environment to be supported in Virtual Life Support, please contact us so we can discuss your needs.

FAQ - Alley

Hardware

VLS is currently available for Meta Quest 2 and Quest for Business. We intend to support other HMD’s in the future. If you require VLS to be available on other hardware, please contact us so we can discuss your needs.

No, we do not believe we can offer a high quality VR training on smartphones.

Our team has previously developed experiences for simple VR headsets that require you to insert your phone, but these do not offer the fidelity and features required for Virtual Life Support. Instead, we recommend either Meta Quest 2 or Pico 4.

If you do want to experience using an AED on a smartphone please checkout ZOLL’s Virtual Rescue apps, also developed by VR Lab, that are available in the Google Play Store and Apple App Store.

Usage

In our experience, a Meta Quest 2 running VLS lasts around 2 hours on a single charge.

You can use an external tethered battery pack to keep the headset at a constant charge. If this is your preferred option, please make sure that it is comfortable to wear the battery pack and it does not get in the way of your movements, specifically when performing compressions. Instead, we prefer having pairs of headsets to alternate between charging and being in use.

We recommend using a manikin with a realistic chest height, to better reflect the virtual victim in the training. We currently provide presets for the Laerdal Little Anne, but you can use any manikin with Virtual Life Support. The setup process includes a step to specify the chest height of your model, so the virtual victim’s chest lines up perfectly with your manikin.

Troubleshooting

You can attach the manikin to the floor using (velcro) tape for example. Or alternative use a anti-slip mat underneath your manikin. We use a Laerdal Little Anne and have attached the manikin to its carrying bag with velcro tape.

FAQ - manikin with velcro tape

Floor level is calibrated in the headsets guardian system. It is extremely important that this is done right. Together with the manikin height this determines whether compression depth can be accurately measured and calculated. For Meta Quest 2 you can find detailed information here for setting up the guardian.
