Vuzix M400 Review

Vuzix M400 Review

In February of 2020 Vuzix launched their latest smart glass device, the Vuzix M400. The Vuzix M400 is the successor of the Vuzix M300XL. In this review we are going analyze the Vuzix M400 in the following fields: Camera & Display, Comfort & Durability, Hardware & Navigation and Software.

Camera & Display

The Vuzix M400 is the first AR smart glass in the market with a 4K camera. This gives the Vuzix M400 the capability to capture 4K videos. Further, you can take 12.8 megapixels photos with the inbuilt camera. The high quality video capture makes it easier for the remote expert to see what the worker is seeing. A disadvantage is that the Vuzix M400 camera is not separately adjustable from the display. When adjusting the angle of the display (for example, for a better view) the angle of the camera is also adjusted, which can result in odd camera angles.

The Vuzix M400 display is located in front of one eye (left or right) and the angle can be adjusted (together with the camera). The display consists of a small high quality OLED screen. OLED screens are, generally speaking, better with contrast then LCD screens as they can produce a darker black. Therefore, the display of the Vuzix M400 remains clear even in direct light.

Pro’s
– Superior 4K video recording
– The OLED display gives sharp contrast

Con’s
– The camera angle is not adjustable without adjusting the angle of the display.

Comfort & Durability

The Vuzix M400 weighs only 180 grams and is therefore the lightest smart glass available in the market. However, the Vuzix M400 frame rests mainly on your nose and ears which can feel uncomfortable when wearing it for a longer period of time. Further, the battery and camera compartments feel firm and strong, but the frame keeping it together feels very brittle.

The Vuzix M400 is also way more durable than previous models from Vuzix. The Vuzix M400 is dust and water resistant with an IP rating of 67. This means it can withstand being underwater for 30 minutes and survive a constant bombardment of dust. Finally, it’s also fall proof tested to 2 meter drops.

Pro’s
– IP67 certification. dust & waterproof
– Drop tested 2 meters.
– Lightweight

Con’s
– Main frame is fragile

Software

The Vuzix M400 runs on Android 8.1, which gives the advantage that you can manually install Android applications (apk) on the Vuzix M400. Not all Android applications are compatible so testing is recommended. 

To make installing and distributing applications easy, Vuzix set up the Vuzix App store. Before using the Vuzix App store you need to register your Vuzix M400 or other Vuzix devices online, After that you can select applications you would like to install from the Vuzix App Store. These will automatically be pushed to the device(s) of your choice.

The Vuzix app store does not offer any tools to manage groups of devices. This can be very inconvenient when you are trying to manage any large number of devices. For example, when you want to uninstall an application you would have to do this for each individual device. Further, one of the most frustrating parts of the Vuzix App Store is that the website itself is very slow. This has a direct impact on the ease of use. In the Vuzix App store most remote expert platforms can be found. An exception to this is Microsoft Remote Assist 365 and Microsoft teams.

Pro’s
– Android operating system

Con’s
– No group management
– The Vuzix App Store is very slow

Hardware & Navigation

The Vuzix M400 comes with 64GB of internal storage, which is a lot higher than industry average. However, the Vuzix M400 does not support additional external memory.

The Vuzix M400 has a 1000 mAh hot swappable battery. This results in a 2,5 to 3 hour battery life.The short battery life is one of the main disadvantages of the Vuzix M400. Especially compared to the 6 hour battery life of the Realwear HMT-1.

 

The Vuzix M400 is very easy to operate as it can be controlled via voice command, touchpad and navigation buttons. The voice recognition is reasonably stable but not nearly as good as the voice recognition of the Realwear HMT-1. You can select any language for the menu, however, only the following languages have voice recognition: English, Spanish, German, French, Japanese, Chinese. The touchpad navigation works intuitively but can be difficult to use with gloves on. In general, we used the navigation buttons the most. The three navigation buttons can be found on the top of the frame.

Pro’s
– Large internal memory
– Three options to navigate

Con’s
– Short battery life
-No possibility to increase the memory

Conclusion

The Vuzix M400 sets itself apart with the 4K video quality and the fact that it’s the lightest smart glass set on the market right now. Furthermore, the OLED display offers a crystal clear image. However, the lack of firmness in the standard frame reduces the amount of use cases it’s feasible for. In general, as a successor of the M300XL it’s a huge step in the right direction, but it needs some accessories to be extensively used in a heavy industrial environment.
