Augmented Reality / Virtual Reality / Extended Reality
What is AR?
- AR = digital overlaid on reality
- VR = fully virtual immersion
- XR = covers both
What AR, VR, and XR really change is that they let people experience what used to be explained. Training that explained press-crush hazards in 12 slides becomes a 3-minute experience of the machine coming down when a hand is placed wrongly. A bigger change is that scarce hands-on practice opens up. A new hire can repeat an equipment teardown, which comes around only once or twice a year, ten times, without stopping the line. What shifts is the cost structure: equipment and on-site occupancy costs fall, but content production and maintenance costs are new.
Several practical points decide an adoption review. First, space requirements depend on whether you need 3DoF (head rotation only) or 6DoF (walking around the space). 6DoF needs at least 2m×2m of clear space per person. Second, motion-sickness complaints surge when rendering drops below 90 frames per second, so it is safer to keep each headset session under 15–20 minutes. Third, smartphone AR has no additional equipment cost, which favors company-wide rollout, but it falls short of headsets in immersion. And XR is only a way of 'showing' things. It sits on a different layer from a digital twin, which handles equipment data in real time, and without twin data, an AR screen is just a pretty picture.
The most common misconception is that “immersion equals learning”. Without a debrief and assessment after the experience, employees go back saying only that it was fun, and the training record shows a single line: “experience completed.” In many cases, a company buys 30 headsets, has only the two pieces of content made at launch, and the devices end up in storage within six months. Plan content refreshes before you plan device counts. Also, some employees will inevitably be prone to motion sickness, and others will be older or wear glasses. If you make VR a mandatory course with no exemption rule, it can turn into a labor-relations issue. Build an equivalent alternative path from the start.

Consider a hypothetical case. Company A makes auto parts, with 1,200 employees and three plants. Every year, about 180 new and reassigned operators are placed on press lines, and for the past three years pinch-point near misses have recurred at 11 per year. Hands-on practice means stopping the line, and every hour of downtime costs around KRW 4 (≈ US$1) million, so safety training had effectively been limited to 8-hour classroom sessions.
- A safety and health manager grouped the last two years of 11 near-misses by type and found 7 came from a single behavior, 'not cutting power while adjusting a die.' Saying "You can tell them a hundred times and it won’t fix this," the manager proposed building just this one scene in VR.
- A production engineering manager filmed the actual press operating sequence to write the scenario, and the company contracted an outside studio to produce one 4-minute 6DoF piece for KRW 32 million (≈ US$23,900). It bought only 8 headsets at first and ran a pilot at one plant.
- In the first run, 3 of 12 people who wore the headset for 20 minutes straight reported dizziness. The HRD manager split it into two 7-minute sessions with a 5-minute break in between. Motion sickness complaints dropped to one person from the next cohort onward.
- After criticism that the experience alone leaves little behind, a 15-minute debrief was added right after it, in which the team leader asks "Why did your hand go in just now?" The answers are now recorded on a 5-item checklist and uploaded to the LMS.
- Six months later, pinch-point near misses at the pilot plant fell from 6 per half-year to 1, and with line-stop practice eliminated, the company saved about KRW 16 million (≈ US$12,000) in lost production per quarter. It added 16 more headsets for the other two plants and began producing a second piece of content.
