Hannover Messe Highlights the Future of Industrial Augmented Reality

Trying on Microsoft’s $3,500 Hololens 2 at Hannover Messe felt like stepping into the future. The lightweight headset slides over the head, tightened with a ratchet dial for a secure fit. A brief calibration and the world around me transformed into a mixed‑reality overlay. Inside a wastewater blower showcased by Microsoft partner PTC, I could see a red‑lit warning indicating worn gear. The headset prompted me to replace the part, and the virtual components unfolded in front of me, allowing me to remove and install them as if they were real. Hololens 2 tracks hand gestures and supports voice commands, enabling hands‑free interaction.

Hololens 2 debuted at MWC in late February to great fanfare and will be available later this year. The long line of exhibitors at Hannover Messe illustrates how AR—and its spatially advanced cousin, mixed reality—could become integral to future factories. Industrial AR offers technicians context‑aware information directly in their work environment, replacing paper manuals and static screens. It also enhances training, and can streamline SOP creation. Proof‑of‑concept studies with Hololens 2, Google Glass Enterprise Edition, and other headsets report significant gains in production speed and reductions in error rates during assembly and maintenance tasks.

Last year, Microsoft secured a $480 million Hololens contract with the U.S. Army, which could supply 100,000 devices for training and combat scenarios.

Yet the vision of widespread AR headset use in industry is not universal. Sastry Malladi, CTO of FogHorn, notes that smartphones currently have a lower learning curve and can also serve as edge processors. Smartphones are easier to procure and cost only a few hundred dollars, compared with thousands for headsets. Their battery life often supports a full work shift, and FogHorn is collaborating with Honeywell to embed machine‑learning on rugged smartphones.

The 2016 success of Pokémon Go showed that smartphones and tablets can deliver AR, but they require the user to hold the device. Nate Fender, COO of AR startup Ario, is pursuing a multimodal strategy that supports smartphones, tablets, and dedicated headsets. By building a no‑code platform, Ario stays platform‑agnostic, ensuring compatibility with emerging devices such as the Hololens 2, which is available for preorder in select markets and awaits FCC approval in the U.S. and CE compliance in Europe.

Battery endurance remains a critical question for industrial AR headsets. Microsoft estimates Hololens 2 will sustain two to three hours of active use. The enterprise version of Google Glass reportedly offers up to eight hours, though it is not yet commercially available and lacks published specs. Lithium‑ion batteries also carry a small risk of thermal runaway, especially in high‑temperature or explosive environments. Water exposure can further compromise safety. In such settings, integrating a lithium‑powered headset under a hard hat may be ill‑advised.

Google Glass Enterprise Edition’s regulatory guidance advises returning units with drained batteries for service rather than swapping them on site. The headset is certified to IEC 60950‑1, a consumer standard, rather than the industrial IEC 60079.

DAQRI has moved from a smart‑helmet design with dual lithium batteries to smart glasses wired to a detachable rechargeable pack that can clip onto clothing. The Recon Jet Pro, priced at $7,548, includes developer tools and software access, and offers two to five hours of operation with a rugged build.

Vuzix sells smart glasses for just over $1,000, targeting field service, logistics, remote support, and manufacturing. Intel’s acquisition of AR startup Recon further signals interest in enterprise‑grade solutions.

Other AR vendors—Atheer, Upskill, and Ario—focus on software first, enabling rapid deployment across multiple hardware platforms.

Industrial AR could revolutionize specific use cases such as training, field service, and logistics, but its broader adoption will likely be limited to well‑defined scenarios in the near term. PTC’s Vuforia team is simplifying AR software creation for smartphones, tablets, and headsets, a development that bodes well for long‑term growth. A 2018 Gartner study found B2B AR applications “gaining traction” as enterprises recognize workflow benefits. The study also predicted that advancing head‑mounted displays would unlock more compelling hands‑free use cases.

Hololens 2 and similar devices point toward a future where training is delivered in 3D rather than flat pages. In AR environments, users can view real‑time functional data superimposed over the physical world, effectively giving them X‑ray vision. While visionary companies will embrace the technology’s potential, pragmatic firms may seek a clear ROI. Time will decide whether AR headsets become staples for select industrial applications, but for now the smartphone remains the default tool.
