Do You Know the Difference Between AR, VR and MR?

Are you comfortable with the terms and the different possible uses of these new immersive technologies?

We're seeing more and more of these abbreviations in the media and on social networks, but it isn't always easy to tell them apart and understand what distinguishes them.

Here are a few tips to help you find your way around:

📌 Virtual Reality (VR)

This makes it possible to create a simulated 3D environment in which the user can interact with virtual objects and people. This immersion is usually achieved using a headset or a projection system that displays images in real time based on the user's movements. VR can also include interfaces that let the user feel tactile sensations, as well as sensors that track their movements to create a more realistic immersive experience.

📌 Augmented Reality (AR)

This is the fusion of reality with elements generated by a computer system in real time. The term generally covers all techniques that allow virtual objects to be credibly inserted into a sequence of real images. When the user points a device at a specific object or place, the AR software analyses the environment in real time and adds virtual elements to the image captured by the camera. These elements can be interactive, letting the user manipulate or modify them based on their environment.

📌 Mixed Reality (MR)

Mixed reality combines elements of virtual reality (VR) and augmented reality (AR) to create an experience that integrates virtual objects into the real world interactively and in real time. MR uses devices such as special glasses or headsets equipped with cameras and sensors to create an immersive experience where virtual objects can be anchored in the real world, so the user can interact with them as if they were real. MR also lets the user move freely through the environment while interacting with virtual objects that can be modified or manipulated based on the real environment.

📌XR (eXtended Reality) is an umbrella term that covers all immersive technologies seeking to create interactive, realistic virtual experiences, including virtual reality (VR), augmented reality (AR) and mixed reality (MR).

And we'll end with that huge playing field that is artificial intelligence

and why we connect our conversational agents to AI to make them more powerful and effective in our training experiences!

Which immersive technology should you choose to train your employees?

The choice between VR, AR and mixed reality depends above all on the instructional goal and the training context. Virtual reality (VR) is particularly well suited to high-risk scenarios — technical gestures, crisis management, safety — because it immerses the employee in a fully simulated environment, with no real danger. Augmented reality (AR) is better suited to training in a real work setting: it overlays useful information on the physical environment, ideal for industrial maintenance or guided on-the-job assistance. Mixed reality (MR) combines both, offering maximum interactivity between the real world and virtual objects. Finally, if a company wants to cover several use cases with a single strategy, the term XR (eXtended Reality) refers to this overall ecosystem. An audit of business needs and logistical constraints is the essential starting point for making the right choice.

VR or AR: which is more effective for professional training?

The comparison between VR and AR for professional training depends on the type of learning targeted. VR excels in fully immersive scenarios: it lets learners repeat complex gestures and simulate stressful situations (a difficult interview, an industrial accident, a medical intervention) in a safe setting. Studies show that retention rates in VR can reach 75%, compared with 10% for traditional classroom training. AR, meanwhile, is more effective for learning in a real-world context: the learner keeps their eyes on their workstation and receives real-time instructions, which reduces errors and speeds up skills development. The two technologies are complementary: VR for skills acquisition, AR for operational assistance. The optimal choice depends on budget, available hardware and on-site constraints.

What is XR, and why does it matter to HR teams?

XR, or eXtended Reality, is an umbrella term that groups together all immersive technologies: virtual reality (VR), augmented reality (AR) and mixed reality (MR). For HR and L&D (Learning & Development) teams, XR represents a major strategic opportunity. It makes it possible to train employees in behavioural skills that are hard to practise in a classroom (communication, leadership, stress management) through realistic simulations with avatars or AI conversational agents. It also offers a measurable advantage: XR modules generate precise data on learner behaviour — reaction time, errors made, progression — enabling individualised tracking that's impossible with traditional formats. In a context of fierce competition for talent and accelerated upskilling, XR is emerging as a differentiator for training and retention strategies.

How does virtual reality training actually work?

Virtual reality training happens in several steps. The learner puts on a VR headset (standalone or connected to a PC) and finds themselves immersed in a 3D environment that faithfully reproduces their professional context: a workshop, a meeting room, a construction site, a care unit. They interact with this environment using controllers or their gaze, depending on the instructional scenario. AI-powered conversational agents can play the role of customers, colleagues or patients, making the interaction more realistic and adaptive. Every action the learner takes is recorded: the instructor or the LMS receives a detailed report on the decisions made, the errors, and the time spent on each step. The training can be repeated as many times as needed, which encourages learning by doing. A VR module typically lasts between 5 and 20 minutes, making it compatible with the operational constraints of frontline teams.
