In this article we’ll review the RealWear HMT-1 AR smartglass which was launched in 2017. The RealWear HMT-1 rapidly became the market leader in the industrial smart glasses category. Leaving its competition behind by creating a very focused product specifically aimed for remote expert use cases. In the first quarter of 2020 competitors Microsoft and Vuzix launched the Vuzix M400 and the Microsoft Hololens 2 to regain market share. Therefore, it’s time for an extensive review of the RealWear HMT-1.
In this RealWear HMT-1 review we’ll compare the quality in 5 area’s: Camera & Display, Comfort & Durability, Software, Hardware & Navigation.
RealWear HMT-1 camera and display
The RealWear HMT-1 is equipped with a full HD camera that can film at a stable 30 frames per second. In general, the camera quality is more than sufficient to provide remote support to somebody wearing a RealWear HMT-1. Further, the camera allows you to take a high-resolution photo at 16 megapixels. In comparison, the new Iphone 11 has a 12 megapixel camera. So in case you need a detailed image, the RealWear HMT-1 has you covered.
The RealWear HMT-1 display is located in front of one eye (left or right) and the viewing angle can be easily adjusted. The display is small and therefore it can be hard to see detailed information. When using the RealWear HMT-1 it is important to position the display at an appropriate angle and distance in front of your strong eye. Otherwise detailed information or reading documents can become a difficult task.
Pro’s
– Good video quality
– Great photos
Con’s
– Small displays make it difficult to interpret detailed information.

Comfort and durability of the RealWear HMT-1
The RealWear HMT-1 is the most rugged smart glass in the market and specifically built for rough industrial environments. The frame of the RealWear HMT-1 is very firm and can even handle a 2 meter drop without issue. Furthermore, it can handle strong jets of water and dust exposure as it is IP66 rated. Also it is possible to order the ATEX approved edition.
Wearing the RealWear HMT-1 is relatively comfortable. It’s easy to put on and remains stable on your head. For increased comfort, we recommend purchasing the RealWear HMT-1 Workband as it divides the weight of the RealWear HMT-1 more equally. Regarding the display, It does require some time to get used to.
Finally, you can easily turn or reposition the camera and display separate from each other, so the remote expert and you both have an optimal view.
Pro’s

RealWear software
The RealWear HMT-1 runs on an Android 8.1 operating system. This has two advantages. First, the user interface of the RealWear HMT-1 is very similar to an Android tablet, which makes it intuitive to operate the RealWear HMT-1. Second, it is possible to manually install Android applications (.apk). Not all Android applications work smoothly, so testing is required.
Foresight is RealWears cloud environment where devices are registered and managed. In Foresight a RealWear device can be assigned with “Policies”. Policies can be created in Foresight and consist of a number of applications you would like to have installed on your device(s). Applications can be selected from the RealWear application catalogue in Foresight. It is also possible to upload your own application into Foresight and then publish it via a “policy” to the devices.
In general Foresight is easy to work with. It takes some time getting used to creating policies instead of directly working per device, but especially with a large pool of devices the advantages of working with policies soon become apparent.
The largest frustration from working with Foresight is waiting for the devices to update, this should happen automatically, but sometimes can lead to an error screen. This can lead to frustration, so start in time and ensure enough time is planned in for the installation!
In general most remote expert software platforms support the RealWear HMT-1. A unique possibility of the RealWear HMT-1 is that it is also possible to use Microsoft Teams. Microsoft Teams is officially still in pilot on the RealWear HMT-1, but if you have a existing Microsoft Teams account you are free to use it.
