Vuzix M400 Smart Glasses

Vuzix M400 Smart Glasses

The Vuzix M400 is an industrial, monocular smartglass designed for hands-free operation. The device operates as a standalone Android computer, equipped with its own processor, memory, camera, microphones, speaker, Wi-Fi and Bluetooth connectivity, and GPS receiver. It does not require a constant connection to a smartphone or computer.

The glasses can display work instructions, documentation, diagrams, checklists, and data from enterprise systems, as well as record video, scan barcodes, and transmit the user's view to a remote expert. Typical applications include field service, maintenance, manufacturing, quality control, warehousing, training, telemedicine, and remote technical support.

The M400 utilizes an opaque, monocular OLED display placed in front of one eye. This means the device should be classified primarily as an Assisted Reality solution, rather than as a classic, see-through AR glasses that superimpose an image directly onto the surroundings. A transparent waveguide display is used in a separate model, the Vuzix M4000.

Software Required for Operation

The Vuzix M400 is a standalone device – it does not require a smartphone, computer, or external computing device for basic operation.
The required system software is the modified Android operating system supplied with the device. Older devices can run on Android 11, and the manufacturer offers a migration option to a version based on Android 13.
The easiest way to download applications is to connect the M400 to a Wi-Fi network and associate the device with an account in the Vuzix App Store.
A specific business application is selected for the intended use, such as remote support, video conferencing, warehouse management, code scanning, work instructions, or integration with an ERP (Enterprise Resource Planning) system.
Remote collaboration can be achieved using applications or connectors supporting Microsoft Teams, Zoom, Webex, or third-party solutions available in the Vuzix App Store.
Communication applications may require a separate user account, license, or subscription for the relevant platform; purchasing the glasses does not automatically include the purchase of all third-party service licenses. The Vuzix Companion App for Android and iOS is optional software. It allows you to configure settings, manage notifications, communicate with your smartphone, and remotely control device applications. It is not required for basic, standalone operation of the M400.
An MDM (Mobile Device Management) system is optional but recommended for larger corporate deployments, as it allows for centralized configuration, security, updating, and control of a fleet of devices. The M400 is compatible with MDM solutions from various vendors.
Upgrading from earlier versions of the system to Android 13 requires the M400 Upgrader Tool, which runs on a computer and a USB connection. This procedure restores factory settings and erases applications, data, and settings from the device, so you should back up your data beforehand.

Developer Software

Standard applications can be developed just like Android applications.
The manufacturer specifies compatibility with applications compiled for a minimum of Android SDK 27; for devices with newer software, a minimum of SDK 30 can be used.
App development can be done using Android Studio or another environment supporting Android application development.
Speech recognition features may require the Vuzix Speech SDK.
Barcode scanning features may require the Vuzix Barcode SDK.
The manufacturer provides the Vuzix Connectivity SDK for communication between the app running on the M400 and the mobile app.
