With the help of smart service solutions such as bitnamic CONNECT, downtimes can be shortened and travel costs saved – especially in combination with augmented reality, or AR. In contrast to VR (virtual reality), real sensory stimulation remains present in AR. This means that reality is not replaced by a virtual world, but merely extended by virtual elements.
Augmented reality can be used with the aid of AR glasses, for example. Special smart glasses for industry are ideal for service and maintenance processes.
In the following article, you will learn about the advantages of using smart glasses in industry, the differences between the mentioned individual models, and which smart glasses are suitable for which areas of application.
Smart glasses in industry – Advantages of Remote Maintenance
Executing maintenance and service processes efficiently regardless of location – digitization in the form of remote maintenance makes it possible. Software solutions like Remote Maintenance, the main component of bitnamic CONNECT, connect a service technician on site with a remote expert in an interactive video conference.
Simply started via app, solutions can be communicated quickly and easily. Useful functions such as data exchange, laser pointer or the integrated whiteboard, which can be used to create screenshots and make annotations, additionally accelerate trouble-shooting.
Even better traceability and easier working on machines ensures the combination of Remote Maintenance and smart glasses: Smart glasses display context-relevant information directly in the user’s field of vision via an integrated camera – the expert sees what the technician sees.
Smartphone, tablet or laptop are no longer needed. Thus, the technician on site has both hands free and can follow the instructions of the expert step by step.
The best smart glasses for industry
Augmented reality offers new opportunities regarding maintenance and servicing processes in industry. Practical use is efficient and intuitive – with the right smart glasses. Based on our experience, we recommend the following three smart glasses for industry: Microsoft HoloLens 2, RealWear HMT-1 and Vuzix M400.
In our bitnamic CONNECT smart glasses guide for augmented reality maintenance you will find more information about AR and the models described below. All three smart glasses are compatible with Remote Maintenance.
Test: Microsoft HoloLens 2
The Microsoft HoloLens 2 are mixed reality smart glasses that augment reality with virtual three-dimensional elements by integrating them into the wearer’s field of vision. The objects can be placed anywhere and always remain in their original position thanks to spatial anchoring, even if the user changes his position.
The camera of the head-mounted display (HMD) is located directly in the center, so the expert’s view is almost identical to that of the HoloLens wearer. The smart glasses are controlled by voice command, so that both hands are always free to work on the machine. The smart glasses can also be controlled with gestures.
Test: RealWear HMT-1
In contrast to the AR glasses by Microsoft, the Android-based HMT-1 by RealWear do not have a direct reality overlay – it is more like “AR light“. The model has a camera attached to the side of the head and a 2D assistant screen located in the peripheral field of vision.
Information can be exchanged via the screen of the RealWear HMT-1 using Remote Maintenance. This allows the service technician to transmit his field of vision to the expert. In parallel, data such as videos, 3D models, documents, application windows, etc. can be received from the helpdesk via screen sharing. The integrated microphone also enables verbal communication.
Test: Vuzix M400
The Android-based Vuzix M400 also does not have a direct reality overlay. The smart glasses have a 2D display in front of the left or right eye, too, but the camera is located directly in front of the display in this model.
The M400 can be operated via touchpad, head movement or speech. Just like the HoloLens 2 and the HMT-1, videos, pictures, documents, 3D models, etc. can be exchanged between the expert and the wearer of the smart glasses via Remote Maintenance.
Smart glasses for industry by comparison
Basically, the HMT-1 and the M400 have more in common, while the smart glasses by Microsoft clearly differentiate themselves visually, technically and in terms of price.
The display of the HoloLens 2 is equipped with transparent holographic lenses and is located in front of the wearer’s eyes in the form of a visor. The centrally located camera directly above it ensures that the perspective of technician and expert is almost congruent.
The camera as well as the display of the HMT-1 and M400 are mounted on the side, but the viewing angle can be easily adjusted.
The weight of the HoloLens 2 is 566 grams and turns out to be the highest compared to the other two smart glasses. Due to the ergonomic design and the option to flip up the display, it still excels in wearing comfort.
The HMT-1 is slightly lighter at 380 grams, while the M400 weighs just 190 grams, making it one of the lightest smart glasses on the market.
There are significant differences in terms of battery life: the HoloLens 2 can be actively used for about two to three hours. The runtime of the HMT-1, on the other hand, is a good five hours.
The M400 is roughly in between: Depending on the choice of external battery, its battery lasts for two to twelve hours.
The HMT-1 and M400 are close to each other in terms of cost, and the price of both smart glasses varies depending on the accessories. The HMT-1 model starts at about 2,200 Euros, the M400 at about 1,800 Euros.
With a price of 3,849 Euros, the HoloLens 2 is a good twice as expensive as the HMT-1 or M400, but has a much wider range of technical possibilities.
Possible uses of smart glasses in industry
In terms of robustness, the HMT-1 ranks first: it is insensitive to dust, dirt and falls from a height of up to two meters on concrete. Fully functional in extreme cold or heat (from -20°C to 50 °C) and waterproof with an IP of 66, the smart glasses are especially suited for outdoor use.
The M400 is also drop-proof, dust-proof, and protected from temporary submersion in water with an IP of 67. It is slightly more fragile than the HMT-1, but also designed for wet, dusty environments.
Both smart glasses just mentioned are commonly used on construction sites, in production, the oil industry, gas industry as well as the automotive industry due to their (structural) properties.
The Microsoft HoloLens 2, especially its display, is more sensitive and therefore ideal for indoor use. It is mostly being used in healthcare and in the manufacture of complex products.

Smart glasses, which are not suitable for industry
With the rapid expansion of digitization in the industrial sector, the range of smart technology is growing at the same time. This also applies to smart glasses: In addition to the three models presented, there are a large number of other smart glasses. Apple is also said to be developing a pair of smart glasses. But not all of them are suitable as smart glasses for industry.
The smart glasses by Google, for example the current model Google Glass Enterprise Edition 2, is particularly light with a weight of just 80 grams and can therefore be worn comfortably over a longer period of time. However, it is not designed for more extreme weather conditions, contact with water, dust or dirt – in other words, for outdoor use or “rough” indoor environments.
Among the better-known smart glasses are models from Oculus, such as the Quest 2, which are classified as VR glasses, i.e., they provide complete immersion in a virtual world. In the context of maintenance, repair and service, an extension of reality and thus the use of augmented reality or mixed reality is recommended. VR glasses such as the Oculus Quest 2 or the HTC Vive are therefore primarily found in the gaming sector.
Smart glasses for industry and Remote Maintenance for more efficient workflows
Remote maintenance in combination with smart glasses is the next step towards Industry 4.0. It ensures shorter production downtimes, lower costs and a better CO2 balance, as time-consuming travel can be avoided. Especially in these challenging times, more and more companies attend to the digitization of their workflows.
