Epson Moverio

Epson Moverio

Epson Moverio is a family of professional, transparent smart glasses designed to display digital content without obscuring the real world. They are optical see-through devices, not closed VR (Virtual Reality) goggles.

The image is displayed in front of both eyes simultaneously, allowing the user to see instructions, documents, video, subtitles, or AR (Augmented Reality) elements while maintaining awareness of their surroundings and freeing their hands. Moverio uses Si-OLED (Silicon Organic Light-Emitting Diode) microdisplays, providing high resolution, contrast, and transparency in unused areas of the image.

Key applications include:
remote technical and service support;
transmitting images from an employee's perspective to an expert;
displaying step-by-step instructions;
on-the-job training;
quality control, inspections, and maintenance;
presenting 2D and 3D models and content in augmented reality;
Live subtitling and translation during events;
Visit museums, exhibitions, and tourist attractions;
Use the glasses as a private screen when working in public spaces.

Available Models

Moverio BT-40 – lightweight glasses without a camera and controller;
Moverio BT-40SN – BT-40 kit with the BO-IC400N intelligent controller;
Moverio BT-45C – ruggedized industrial model with a camera, no controller;
Moverio BT-45CS – complete BT-45C industrial kit with the BO-IC400N controller.

The BO-IC400N controller is also available in the European Epson catalog as a separate product, but it is not a separate glasses model.

Software required for operation

Basic image display

For the BT-40 and BT-45C, no specific Epson software is required for the device to display a standard image. The glasses function similarly to an external USB-C monitor, provided the source device supports DisplayPort Alternate Mode and provides adequate power.

Content displayed on the glasses comes from an app running on:
a smartphone;
tablet;
computer;
BO-IC400N controller.

The functions of the camera, sensors, communication with the expert, AR instructions, or subtitles depend on the appropriate software running on the source device.

MOVERIO Link

MOVERIO Link is an Epson utility designed primarily for glasses connected to a compatible Android device.

The program allows you to:
manage display settings;
change brightness;
switch between 2D and 3D images;
configure certain audio settings;
control selected Moverio-specific features.

Not all Android devices are compatible with MOVERIO Link, so please check the compatibility of your specific phone or tablet.

MOVERIO Link Pro

MOVERIO Link Pro is pre-installed on Moverio controllers used in BT-40SN and BT-45CS configurations.

The program allows you to:
configure the image;
change the apparent screen distance;
switch between 2D and 3D;
change the controller's operating mode;
configure the BT-45C audio;
manage additional headset features.

Apps for the BO-IC400N Controller

The BO-IC400N controller does not support:
Google Play;
Google Mobile Services;
standard services such as Gmail or Google Maps requiring GMS;
the former Moverio Apps Market.

Apps for the controller must be installed as APK files [Android Package Kit] using the built-in Files/Filer application or through mechanisms designed for enterprise deployments.

Software for Remote Support and AR Applications

The glasses themselves do not constitute a complete remote support system. Such applications require a dedicated app that performs functions such as:
camera image transmission;
two-way voice communication;
connecting a technician with an expert;
transferring photos and documents;
annotating images;
displaying instructions;
recording the session.

This can be an app provided by an Epson software partner or a custom-made solution. Epson provides the hardware platform and development tools, but the specific software depends on the scenario being implemented.

Developer Tools

Available for applications created specifically for Moverio:

Moverio Basic Function SDK [Software Development Kit] – support for the display, camera, sensors, and audio;
SDK versions for Android and Windows;
Unity plugin;
Sample projects and API documentation;
Moverio Controller Function SDK – support for BO-IC400/BO-IC400N controller functions;
MAXST AR SDK – an additional AR platform optimized for the BT-45CS.

Updates
The BT-40 and BT-45C glasses' firmware is updated using a dedicated tool for Windows computers;
The BO-IC400N controller system can be updated over-the-air (OTA);
Epson recommends using the latest firmware for increased stability and compatibility with computers and laptops.

Key Distinctions
BT-40 – Best as a lightweight, private display or a display connected to an existing device;

BT-40SN — BT-40 with a standalone Android controller, designed for turnkey commercial deployments; BT-45C — industrial glasses with a camera, requiring an external control device; BT-45CS — a complete industrial solution with a camera and a dedicated controller.
