The Epson Moverio BT-40 is a consumer augmented reality smart glasses developed by Epson, released in March 2021. The BT-40 features Epson's Si-OLED technology delivering Full HD 1080p binocular displays with an exceptional 500,000:1 contrast ratio, appearing like a 120-inch screen from 16 feet away with a 34° field of view. Using plug-and-play USB Type-C connectivity with DisplayPort Alt Mode, the glasses work with compatible smartphones, tablets, and laptops without requiring onboard processing. Available as the basic BT-40 ($579) or BT-40S ($999) with an intelligent Android touch controller, the Moverio BT-40 targets AR development, entertainment, and personal viewing applications.

History and Development

Epson announced the Moverio BT-40 in March 2021 as the next generation of its Moverio AR smart glasses line. The BT-40 simplified the design by using USB-C tethering to host devices rather than integrated processing, reducing weight and complexity while delivering superior display quality. The BT-40S variant includes the BO-IC400 intelligent touch controller running Android 9.0 for standalone AR applications. The Moverio line has been a pioneer in see-through AR glasses since the original BT-100 in 2011.[1]
