AR or VR: which “reality” is right for your organisation’s learning needs?
/The use of technology in training is nothing new but learning and training specialists now have so much more to choose from and the choice is getting greater.
According to Digi-Capital’s Augmented/Virtual Reality Report Q2 2018 augmented and virtual reality start-ups raised over $3.6B USD from venture capital in the 12 months up to the end of Q1 2018.
With this much investment going into the technology there must be something in augmented reality (AR) and virtual reality (VR) of value to today’s learning and training specialists – but which one is right for you?
Notwithstanding the known benefits of using simulations in training – increased safety, reduced risk, reduced need for real equipment, learning while having fun – there are other factors to be considered when deciding between the use of AR and VR as your simulation media. In MMCLD’s experience, the suitability of AR or VR as a media for learning solutions is driven by a number of underlying principles.
To start with there is the definitional difference between VR and AR.
VR creates an environment or “virtual world” that the learner and training equipment can be inserted into – think Sam Worthington in Avatar. Like Sam Worthington’s character, the learner can experience all elements of the virtual world they are training in albeit there are often restrictions on “physical” connections. By “physical” connections we mean that the learner’s options to use real, physical assets can be restricted. In a lot of instances such a restriction may have minimal impact on the learning effect but for operators or maintainers of specialised equipment, experiencing the physical feel and responses of real controls or tools can accelerate the transfer of learning from the classroom to the workplace.
In contrast, AR inserts equipment or assets into an existing environment, that is the real world whether that be a workplace or a classroom. Using the existing real-world environment can extend the learning experience through creation of layers of digital information on top of real equipment or the actual physical environment.
On the downside the real world can also restrict the authenticity of the learning environment if there are conflicting visual information or cues. For example, when overlaying an AR traffic accident scene in a classroom the learner will still see the tables and chairs in the room, which can detract from the “realism” of the scenario.
Then there is whether the learning is for operation of equipment or devices in “static” or “motion” mode.
When we refer to equipment or devices being in “static” mode or “motion” mode, we’re referring to whether the equipment is in motion relative to the learner or whether it is anchored to a set location. MMCLD has found that, depending on the AR device used, AR is generally more suitable when “operation” is conducted on equipment or assets in a “static” mode not a “motion” mode. This is because of the technical functionality of devices such as the HoloLens which anchor the equipment or asset to a single position in the classroom or area where the training is being delivered. This anchoring allows the learner to move the equipment or move around the equipment but does not allow the equipment to move from the anchored position.
“Motion” mode learning scenarios such as first person shooter (FPS) type scenarios, are better addressed using VR. FPS activities typically map the learner’s movements and provide a view of what an actual person would see and do. VR allows the learner, equipment or assets to all move within the virtual environment. To achieve the same level of “motion” in an AR environment would rely on the AR being overlayed on an existing environment that is a high-fidelity replication of the real operational environment with the added need for any equipment or assets in the environment being able to move relative to the learner.
As is the case when designing any learning solution, the feasibility of using different method and media along with consideration of learning and assessment strategies is needed to identify the most appropriate and effective solution for delivery of your training. The principles outlined above are just a few of the many that should be considered when you’re deciding on whether AR or VR is the right media for your training requirement.
