The future of training is in immersive learning
Humans learn best by doing. The ancient Greek philosopher Aristotle wrote that “for the things we have to learn before we can do them, we learn by doing them”. Since then, his point has been proved time and again: “active learning” helps people learn faster, retain information for longer, and fail less often.
Today, virtual environments are providing firms worldwide with a safe, interactive place for active learning and training. The technology required is tried, tested, and affordable.
Learners can interact within a 3D virtual environment, and learn procedural tasks or simulate interactions almost as naturally as they would on the job. This helps people to learn faster and remember for longer. Trainers are no longer restricted by location (a big benefit during the pandemic), environment, or risk. In addition, people can learn safely from their mistakes.
Thanks to the technology that’s powering virtual and mixed reality, Aristotle’s paradox – the idea that we can only really learn to do something by actually doing it ourselves – has finally become achievable.
Creating VR training - Headsets explained
We’ll start with an overview of the tech. Most people are aware of VR headsets, but AR and MR (augmented and mixed reality) headsets also offer significant potential for immersive learning. When the term VR is used in this blog, you can generally assume that AR or MR headsets might also be used.
- Virtual reality (VR) is a 3D, entirely digital environment. With a VR headset the user is completely immersed in a virtual world. VR headsets are currently the most widely available and affordable option.
- Augmented reality (AR) puts the user in the real world, but overlays digital elements onto it. Most people are familiar with AR on mobile phones, but specialized AR headsets can be very effective for immersive learning.
- Mixed reality (MR) blends fully virtual, augmented, and real world elements. This is achieved via video “pass-through” technology, which uses cameras to digitize the world in real time, and combines that data with virtual content.
- Extended reality (XR) is simply the umbrella term to describe all of the above. Extended reality is also closely related to the concept of the metaverse – the idea of a world where immersive digital content is pervasive.
Creating VR training - Beyond the headset
Interaction is at the core of the VR experience. This means that effective virtual training requires a lot more than just a headset. Users need to be able to engage easily with and respond to the world they’re immersed in.
There are multiple interaction options available, and the choice of which to use is as important as the choice of headset. It’s particularly critical in immersive learning, where users may be inexperienced or technology-anxious, quick onboarding is key, and training outcomes often depend on effectively mapping virtual interactions to real-world ones.
Interaction options in VR include:
- Controllers: Hand-held devices with buttons and joysticks, similar to gaming controllers.
- Hand tracking: Cameras embedded in or attached to headsets that capture users’ hand movements.
- Eye tracking: Technology inside a headset that captures where you are looking.
- Voice control: Similar to Alexa, but in VR. Currently accuracy remains a challenge.
- Body tracking: Tracks the position of a user’s whole body. Currently largely experimental.
Why now is the time for VR training
What does it take to send an emerging technology into the mainstream? Academic theory suggests that for widespread adoption, VR training needs to clearly demonstrate real-world impact, and reduce both the real and perceived effort of learning to use a new technology.
Both of these areas are close to being solved by VR training, putting it on the cusp of mainstream adoption at scale.
1. The tech is ready
Immersive technology was once only suitable for ultra-high-end and time-intensive training programs such as flight simulators. But it’s now within reach of businesses of every shape and size.
The VR industry is also moving beyond relying on gaming controllers for interaction. Hand tracking and eye tracking are now widely available, allowing users to interact more naturally within the virtual environment. This improves training outcomes, reduces the effort of adoption, and makes VR training applications more accessible.
Finally, the development of scalable enterprise content creation and management platforms has made deploying VR training easier than ever before.
2. Hybrid working is the new normal
More than 80% of firms now operate hybrid working as standard, according to the UK’s Chartered Institute of Management. Training in virtual environments makes location far less of a barrier.
Anyone can be trained from anywhere in the world, while still interacting naturally with colleagues and trainers.
3. ROI data from early adopters is convincing
We know VR training works. Businesses worldwide are already implementing VR for training and have shared the results.
Strategic business decisions are being taken today based on the data VR training produces. It’s no longer the preserve of early adopters.
We'll dive more into the data showing effectiveness of VR training in the next section.
Is VR training effective?
Indications are that VR training can offer significant benefits over in-person or online learning across a range of measures.
Of course, this depends on your particular training scenario. Training a barista is very different to training a fighter pilot. But early data strongly supports the principle that VR training can offer significant benefits in cost saving, knowledge retention, and improved productivity.
VR training benefits
Making a business case for VR would typically rest on some (or all) of the following benefits, depending on your particular industry and training scenario.
- Saves time: Immersive training experiences help people learn faster. A 2020 study from PWC found that VR learners completed training four times faster than in a classroom, and 1.5 times faster than online training.
- Saves money: Training can be rolled out to multiple locations and, unlike live training, can easily scale and repeat. A study into the use of VR for training neonatal intensive care workers showed a 50% reduction in training costs over 3 years compared to traditional training.
- Increases engagement: A realistic environment is vital for soft skills and procedural training. PWC found that learners were 3.75 times more emotionally connected with training content when it was delivered within a virtual environment.
- Improves recall: When learners are fully engaged physically and emotionally, they retain more information, for longer. Dr. Narendra Kini from the Miami Children’s Health System found that retention levels a year after a virtual training session can be as much as 80%, compared to 20% just a week after classroom-based training.
- Improves safety: Training onsite is a challenge for industries where locations can be difficult or dangerous to access. If you’re training wind turbine engineers or submariners, an immersive, virtual environment is a much safer place for people to learn. In addition, people can repeat procedures as often as they like, learning from their mistakes with zero risk.
- Improves analysis: The digital nature of VR training captures data in real time. This can provide in-the-moment feedback to trainees, as well as large-scale impact analysis, which quickly proves results to boards and senior stakeholders.
Training, not gaming: The barriers to adoption of VR
The opportunities for VR training are huge and the benefits have been proved. But within organisations there are still significant barriers forward-thinking managers and innovators need to overcome before broad acceptance.
The decision makers within a business are often time poor, and risk averse. They might feel understandably sceptical about investing in technology that has historically been associated with gaming, which they might in turn have to defend to the CEO or Board.
Trainees themselves can be nervous and similarly sceptical in advance of their first VR training session – although they often become strong advocates straight afterwards.
4 ways hand tracking helps overcome barriers to adoption of VR training
Historically, immersive training has relied on using controllers in conjunction with VR headsets. But those controllers were built for gaming, not training. Trainees are more diverse than gamers, and don’t have time to learn how to operate a new technology before they can start learning.
While it’s not the only factor, hand tracking plays an important part in overcoming barriers to adoption of VR training.
1. Reduces onboarding time
Hand tracking reduces onboarding time. With a well-designed launcher powered by hand tracking, users can put on a headset and start immediately, with instructions incorporated into the training application itself.
2. Reduces perceived effort
Many trainees will not have much prior experience or even interest in VR. Hand tracking technology reduces friction and makes immersive learning accessible, regardless of age or experience.
3. Makes VR procedural training more effective
Muscle memory is an important factor in helping procedural learners commit tasks to long-term memory. Using hand tracking means users are learning, and retaining, how to do something almost exactly as they would have to do it in the real world.
4. Makes VR soft skills training more effective
Every culture gestures with their hands while they talk. Hand tracking enables richer and more lifelike communication in virtual environments. This in turn creates more realistic virtual soft skills training.
Virtual reality and training in practice
From its early roots in flight simulators, virtual and mixed reality technology is now training people right across the workforce. In particular, VR’s application for both procedural training and, separately, soft skills training is proving to be highly effective.
In practice: Virtual reality industrial and retail training
VR is highly effective for procedural training in retail or industrial settings. Examples include learning a production line process, or training retail staff such as baristas.
It means learners can experiment safely, learn from their mistakes, and repeat tasks as often as necessary to develop muscle memory for long-term recall.
In practice: VR in medical training
The immersive nature of VR is being used as an “empathy machine” by companies such as Embodied Labs. Their award-winning VR experiences give healthcare workers a first-person look inside what it’s like to live with common conditions that affect seniors – such as Alzheimer’s and macular degeneration.
VR is also used for procedural training in surgery and CPR. TetraSignum’s VR CPR training puts learners in a situation that feels like an actual emergency, improving their ability to respond in a real situation. And by using an AR/MR headset, physical surgery training environments can be enriched with virtual contextual guidance.
In practice: VR soft skills training
Empathy and effective communication are vital for HR and other corporate professionals, who regularly face challenging conversations and interactions.
VR is used to literally put learners in other people’s shoes, and provide opportunities to practise challenging scenarios in a safe space. It’s also been shown to be effective for employee onboarding programs.
In practice: VR aviation training
The airline industry has been quick to embrace VR, building on its roots in pilot training and flight simulators.
Airlines such as Lufthansa are now training flight attendants using immersive technology. A major benefit is that there is no need to ground operational craft or create full-size dummy aircraft for training.
