FAQ

How do I install applications on my M-Series Smart Glasses?

The easiest way to install applications on the M-Series Smart Glasses is to connect the device to Wi-Fi and manage the applications from the Vuzix App Store.  Once you have a valid account, simply click on My Account then My Devices and follow the instructions to register your device to your account.  Applications can then be selected and pushed to your device.

Applications not available on the Vuzix App Store can also be installed. They must be downloaded from 3rd party sites and can then be pushed to the device by following the procedure here.

More FAQ's:

Why are applications from the App Store not appearing on my M-Series Glasses?

Once configured, applications should install to the device automatically.  There are a few possible reasons why this might not occur. 

Network Connectivity

Before troubleshooting the App Store connection, please verify the M-Series Glasses have an active Wi-Fi connection to the public internet.  

Device Configuration 

The most common reason for applications not updating is the M-Series device is configured with communication to the Vuzix App Store disabled. To check this from the M-Series, navigate to Settings > Apps & notifications > Vuzix App Store. The App Store toggle switch must be enabled in order to communicate. 

Once the App Store is toggled, it may fail with the error “App Store connection refused. Is this device properly registered on the app store?” The switch will again appear in the off position. To correct this, follow the Linking to App Store Account section below, then repeat this configuration step. 

Once enabling the App Store is successful, please be sure the M-Series device is configured to Run Actions Automatically. This will keep the device synchronized with the latest updates from the Vuzix App Store, preventing future problems. 

The M-Series device will begin downloading and installing any applications that are out of date. 

Linking to App Store Account 

If the device configuration did not solve the problem, the last step is to verify the device status within the Vuzix App Store. 

Determine the serial number of your M-Series device before continuing. The serial number is printed on the outside plastic of the M-Series device. Please read this from the main M-Series unit, not the battery. It may be easier to read the serial number on the M-Series screen than on the plastic. This is done by navigating to Settings > System > About Glasses > Status and scrolling down until the serial number is displayed. 

From a computer, visit the Vuzix App Store from the Vuzix homepage. Select My Account from the top of the App Store page. Select My Device from the navigation bar on the left. 

If the serial number of your M-Series is not shown, click the Add New Device button, and follow the instructions. If the device serial number is already showing up under My Devices, press the Refresh button (circular arrows) to allow the device to reconnect. 

If any errors occur during this process, please contact Technical Support.  

How can I navigate the M400 Smart Glasses user interface?

For ease of use, the M-Series Smart Glasses offer multiple modes of interaction, including buttons, touchpad, and voice commands.

For details on M-Series Smart Glasses button behavior, refer to the M-Series Smart Glasses Quick Start Guide, available here.

The M-Series Smart Glasses advanced touchpad allows navigation through the interface using single finger swipes (up/down/left/right) in addition to a full set of advanced gestures. For a full list of gestures, refer to the M400 Smart Glasses Quick Start Guide linked above.

For details on voice commands in the M-Series Smart Glasses, refer to the article covering voice interaction here

Can I use voice commands to control the M-Series Smart Glasses?

Yes, the M-Series Smart Glasses Speech Recognition engine includes a set of basic navigation and control commands by default. These commands are globally accessible on the M-Series Smart Glasses while the recognizer is enabled.

To enable, go to the Speech Recognition menu located under Settings > System > Languages & input,  and toggle the “Vuzix Speech Recognition” option. From this screen, you can also modify the sensitivity and timeout settings of the Speech Recognition engine. Sensitivity will adjust the amount of accuracy required by the recognizer when listening for a phrase, and timeout will adjust how long the recognizer will continue listening for commands after the keyword or the last voice command is issued. By default, the timeout is 15 seconds. Setting the timeout slider to the maximum value will set the timeout to an unlimited value, though it is important to keep in mind this will increase battery usage by the recognizer.

To issue voice commands, you must first speak the “Hello Vuzix” keyword to trigger the listener which will remain active for the timeout duration. Issuing additional commands will reset this timeout.

To see a full list of commands, navigate to Settings > System > Languages & input > Speech Recognition > Speech Commands List,  or if speech recognition is enabled, say "Hello Vuzix, Speech commands."

How can I connect my M-Series Smart Glasses to a WiFi network?

For most users, the simplest way to connect the M-Series Smart Glasses to a WiFi network is by generating a QR code using your computer or smartphone and scanning it on your device. Vuzix provides a browser-based tool to generate such a QR code on https://www.vuzix.com/wifiQR. To maintain your security, this tool generates the QR code locally within your browser. The tool does not transmit your SSID or password to our servers.

Once you have a QR code, open the Scanner application located on the M-Series Smart Glasses main launcher, scan the QR code, and click the "Connect To Network" button.  

If scanning a QR code does not meet your needs, you can manually view and connect to networks. 

Open the Settings application and then select Network & Internet > Wi-Fi. Enable the WiFi by toggling Off to On. The device will then scan for available networks. Scroll down to the network you want to connect to and select it. A standard Android keyboard will come up if the network is password protected. Use this keyboard to enter the password. The touchpad and buttons can be used to navigate the keyboard. 

Advanced WiFi settings can be accessed by scrolling down to the bottom and selecting Wi-Fi preferences, then selecting Advanced. This will show you your WiFi MAC and IP address, as well as allow you to modify other advanced settings such as installing certificates.

I’ve installed an application on my M-Series Smart Glasses but I am unable to control it. What can I do?

The majority of Android applications are designed exclusively for touchscreen-based devices. M-Series Smart Glasses use a very different user interface and interaction model compared to traditional Android phones and tablets, and rely heavily upon focus-based navigation for interface objects which most traditional Android applications do not implement. As such, we must consider most Android applications not designed with Smart Glass devices in mind as unsupported.

It is possible to navigate these applications with external input devices such as a Bluetooth mouse/keyboard combination or remote control applications such as Vuzix View, but as the primary objective of using a device such as the M-Series Smart Glasses is to be able to work hands-free, these applications may provide a far less than ideal user experience. 

It is recommended to download apps from the Vuzix App Store since these are known to work on the device.

Can I cast the screen of my M400 and M4000 Smart Glasses?

Yes, the M400 and M4000 has the ability to cast to a Miracast compatible device. 

To enable this feature, navigate to Settings > Connected devices > Cast, and use the dropdown menu to select "Enable wireless display". This will automatically trigger the M400/M4000to search for compatible devices. 

Select the device you would like to cast your screen onto to automatically initiate the connection process. 

Do the M-Series Smart Glasses support the Google Play Store?

No, the M-Series Smart Glasses do not support the Play Store or other Google Mobile Services (GMS) not covered by the Android Open Source license. 

Vuzix hosts an alternative App Store that supports content developed specifically for the M-Series Smart Glasses. 

How can I manage the OTA (Over The Air) update notifications on my M-Series Smart Glasses?

The settings for the M-Series Smart Glasses OTA update notifications mechanism can be found in the Settings application under System > OTA System Update > OTA Monitor Action. This feature has four modes, each will be described below;

Disabled - This option will fully disable the notifications mechanism, preventing the M-Series Smart Glasses from proactively contacting our OTA server to check for updates. 

Notify Only- This option will check for updates any time the M-Series Smart Glasses are powered on and connected to a network with internet connectivity, and will only show a notification icon in the notification drawer. 

Notify and Alert Once- This option will check for updates any time the M-Series Smart Glasses are powered on and connected to a network with internet connectivity, and will show a notification icon in the notification drawer as well as displaying a pop-up notification to inform the user that an update is available. This pop-up has two options, to dismiss the notification or initiate an update. The pop-up notification will display only once per power cycle of the M-Series Smart Glasses. 

Notify and Alert Periodically - This option will function the same as the above, but will display the pop-up notification once per power cycle or once per every 12 hours, whichever comes first.

How can I update the OS on my M-Series Smart Glasses?

The preferred method of updating your M-Series Smart Glasses is via the included OTA (Over The Air) update mechanism, which will require the M-Series Smart Glasses to be connected to a stable WiFi network with internet access. 

Make sure your M-Series Smart Glasses are plugged into a 1.5 amp USB power source. 

  1. Open the Settings application, navigate down and select the System option.
  2. Select the "OTA System Update" option second from the bottom of the list.
  3. Select the "Check Server for Updates" option.
  4. If an update is available, select "Update Now".
  5. Wait on that screen while the update is downloaded. This may take several minutes.
  6. Select "Verify and install" to apply the system update.  Do not power off or interrupt the M-Series Smart Glasses! 
  7. The M-Series Smart Glasses will automatically process the update and reboot.  Your update is complete.

How can I transfer files to/from the M400 and M4000 Smart Glasses?

In order to transfer files from the M400 and M4000 Smart Glasses via USB, you will first need to change the USB mode in Settings. This can be accessed in Settings > Connected Devices > USB to bring up the menu. From there, select the mode for "Transfer files".

Once enabled, you will be able to navigate the file system on the M400 and M4000 Smart Glasses when plugged into a computer via USB. It will appear as a standard USB storage device.
