Frontline AR Glasses

Remote assistance in field service

In remote assistance, a technician streams the view from head-worn glasses to an expert elsewhere, who talks them through a fault and may draw on the shared image. The hoped-for gains are fewer specialist journeys and faster fixes, but they depend on your network, the kinds of faults you see and how well experts coach over video. A systematic review of augmented reality in maintenance, held in Cranfield University's repository, examined 30 primary studies from 1997 to 2017 and found high fragmentation among hardware, software and AR solutions, with technical issues still keeping AR from suiting many industrial uses. Test coverage at real sites, including plant rooms and basements, before assuming remote support can replace visits.

Pick-by-vision in the warehouse

Pick-by-vision shows the next location and quantity in the picker's line of sight, leaving both hands free. Much of the evidence still comes from laboratory trials. A 2022 study in the journal Logistics by Chondromatidis, Gialos and Zeimpekis ran 320 picking runs with 10 participants wearing smart glasses and found that confirming picks with a scanner performed better than an RFID reader. Overall workload, measured with the NASA-TLX method, averaged 32.8, which the authors judged satisfyingly small. Participants, though, averaged 25.1 years of age, and some found slight headband movement annoying. A warehouse trial should include older staff, people who wear prescription glasses and full-length shifts before you draw conclusions.

Matching the headset to the job

The main question is how much the task needs graphics anchored to the world around the worker. Voice-driven headsets with a small display can cover checklists and remote calls, while full AR headsets suit work where instructions must sit on the equipment itself. Listed prices in October 2026 show the spread: the Lenovo ThinkReality A3 at $1,399, the Vuzix Shield at $1,499, the RealWear Navigator 520 at $2,500 and the Magic Leap 2 at $3,299, while the Iristick Z1 was quote-only. The Microsoft HoloLens 2 was listed at $3,500 but marked discontinued, which matters for a rollout planned over several years. Ask every maker about mid-shift battery swaps, helmet mounting and device-management tools.

Running a fair frontline trial

Choose one process with a clear baseline, such as a single repair type or one picking zone, and measure time, errors and rework before any glasses arrive. Run the trial long enough for novelty to wear off, and include night shifts if you run them. Record discomfort alongside output, and let people stop without penalty. Agree in advance what happens to video from remote calls, because it can capture colleagues and customers. Compare results with the cheapest credible alternative, such as a tablet on a stand or voice picking, rather than with paper alone, so you learn whether the glasses made the difference. Share the findings with the people who took part before deciding on a wider rollout.

Common questions

Do AR glasses need Wi-Fi to work on site?

Remote assistance needs a live data connection with enough upload capacity for video, from Wi-Fi or a mobile network. Some instruction and checklist apps can run offline, so ask each maker which functions keep working when the connection drops and how data syncs afterwards.

How long can workers wear AR glasses during a shift?

There is no single limit. Comfort depends on weight, fit, heat and the task, so start with short sessions, collect feedback and extend wear time gradually. Involve occupational health if people report neck discomfort, headaches or tired eyes.
