Epson Moverio BT-300 is a binocular, optical see-through augmented reality headset made by Epson. The glasses connect by cable to their own Android controller, which contains the computing hardware and battery. This page describes the BT-300 and its FPV Drone Edition, rather than specifications shared by every Moverio model.[1][3]
Intro
Epson announced the third-generation Moverio BT-300 at Mobile World Congress in Barcelona on February 22, 2016, initially targeting availability late that year.[4] Its Miracast software supplier sMedio subsequently recorded a Japanese sales start of November 30, 2016.[2] On January 4, 2017, Epson announced immediate US availability of the Developer Edition at US$779 and said the US$799 Drone Edition would become available later that month.[3]
The two editions used the same hardware platform. The Drone Edition was supplied with DJI GO, clip-on dark shades and fasteners for mounting the Moverio controller on a DJI phone holder.[3] These are historical configurations and prices; Epson later discontinued the BT-300.[6]
Features
The BT-300 uses silicon-based organic light-emitting diode (Si-OLED) displays instead of the backlit LCD arrangement of the BT-200. Epson described the change as allowing displayed content to blend into the view through the glasses without a visible display background.[4] The optical system overlays images on the surroundings; its front camera is also available for image capture and application use.[1]
Its display resolution is 1280 x 720 pixels, with an approximately 23-degree diagonal field of view. Epson illustrated perceived image size as equivalent to an 80-inch screen viewed from 5 m, or a 40-inch screen from 2.5 m. These are viewing-angle comparisons, rather than a physical screen at those distances; the manual notes that perceived size varies between users.[1]
At the 2016 announcement, Epson described the BT-300 as more than 20% lighter than the BT-200. Its accompanying claim to be the lightest announced binocular see-through smartglasses was a dated manufacturer claim, rather than a current ranking of all AR headsets.[4]
Hardware
The Moverio BT-300 is connected to an Android controller that has a trackpad and basic Android buttons through a wire.[1] The controller also has a touch-sensitive cross-key, Enter key, volume keys and a Switch key for brightness, 2D/3D mode and key locking. The trackpad supports tapping, dragging, two-finger scrolling and pinch gestures; text is entered with an on-screen keyboard.[1]
A 5-megapixel camera and ambient light sensor are built into the headset. The latter can adjust display brightness automatically. Double-tapping the headset temporarily hides the image and mutes the audio. Audio recording uses the supplied earphone microphone, rather than a microphone included in the headset's sensor list.[1]
The headset can be fitted with its supplied nose pad for use over prescription glasses. Epson specifies glasses approximately 147 mm wide, with fit also depending on their shape. A separate lens holder can instead be fitted with prescription lenses by an optician. The detachable shade reduces surrounding light when the display is difficult to see in bright conditions.[1]
Epson lists 69 g for the headset without the shade and cables, and 129 g for the controller. Its approximately six-hour battery-life figure is an estimate under Epson's evaluation conditions; applications and operating conditions affect actual runtime.[1]

Software
The Moverio BT-300 runs Android 5.1. Epson Australia's product documentation states that it is not Google certified and does not support Google Play services or the Google Play Store.[1][5] The documented preinstalled applications include a browser, Gallery, Camera, Music, Sound Recorder, calendar and email tools.[1]
The manual describes copying media from a computer over USB to the internal storage or a microSD card for playback in Gallery. It also describes Miracast receiving and casting with compatible computers, phones and televisions. Epson does not guarantee all device connections, and its manual says the BT-300 cannot connect to a Wi-Fi access point while using Miracast.[1]
Apps
The original distribution service was MOVERIO Apps Market. The BT-300 manual documented account registration, choosing applications on the device or a computer and queuing installations for the next Internet connection.[1] sMedio offered the television-recording viewer TV Suite for MOVERIO and wireless DVD playback applications through this market, with some functions offered as paid options.[2]
Epson's current closure notice records the market as closed on March 31, 2023.[7] Its earlier closure announcement said that downloaded applications could continue to be used, but could not be restored through the market after device initialization or uninstalling them.[8] These notices do not establish continued operation of third-party online services used by individual applications.
Drone use
Epson and DJI announced their partnership in September 2016. The planned DJI GO integration displayed a drone camera feed while leaving the surroundings visible through the glasses. At the time, the companies named DJI Phantom, Inspire and Matrice aircraft and the Osmo camera among DJI GO platforms.[9] The January 2017 Drone Edition announcement described DJI GO as preloaded and included controller-mounting fasteners and dark shades.[3] This describes the original integration, rather than a compatibility statement for all subsequent DJI aircraft or apps.
Developer
The BT-300 originally had a dedicated software development kit and developer documentation. Epson announced that technical information for this model would cease to be provided on March 31, 2021, alongside the BT-350, BT-2000 and BT-2200 material.[6] The current Moverio Basic Function SDK documentation directs developers of models before the BT-350 to the dedicated SDK for each model. It should not be treated as a replacement BT-300 SDK simply because it bears the Moverio name.[10]
Model-specific research
Azimi, Qian, Navab and Kazanzides used a BT-300 in an original display-calibration study. In the version-4 preprint, its front RGB camera tracked a cube carrying ARTags. Two experienced users each performed ten trials, with 20 alignments for calibration and eight additional alignments for testing in each trial. For the BT-300, the affine transformation gave a mean test reprojection error of 4.60 mm, with a standard deviation of 1.55 mm. The authors deliberately began with inaccurate projection and interpupillary-distance settings. This was a result for their application and calibration procedure within a limited, arm-reach working volume, rather than a general headset tracking-accuracy specification.[11]
A 2024 University of Sassari laboratory comparison tested the BT-300, HoloLens 2, Vuzix M400 and GlassUp F4 for marker scanning, remote calls and battery use. The BT-300's mean time from activating scanning to displaying the encoded information was 5.67 seconds in its QR-code trials at 40 cm. The remote-call tests used a university Wi-Fi connection specified as 20 Mbps upload/download and shared VGA video, with 20 repetitions of the delay tests; reported BT-300 delays averaged 0.43 seconds for audio and 0.55 seconds for video. These task and network measurements do not establish display latency, drone-link latency or performance in a working farm.[12]
