==Design==
The '''Avegant Glyph''' is a unique personal theater and video headset developed by [[Avegant Corporation]], announced in 2015, launched via Kickstarter, and released in 2016 at approximately $599. Unlike traditional VR headsets that use LCD or OLED displays, the Glyph pioneered "Retinal Imaging Technology" (RIT) using an array of two million micromirrors to beam images directly into the user's eyes—a technology that Avegant claimed produced more natural, eye-strain-reducing visuals similar to how humans perceive the real world. The Glyph's innovative form factor resembles a pair of premium over-ear headphones that flip down to become a personal video display, providing a 1280 × 720 (720p) per eye resolution with 40° diagonal field of view—equivalent to viewing a 65-inch screen from 8 feet away. Supporting most video formats including 3D and 360-degree content (with onboard head tracking), the Glyph connects via Micro HDMI to smartphones, tablets, laptops, gaming consoles, cameras, and drones, with built-in diopter adjustment (+1 to -7) eliminating the need for glasses for most users. The device includes high-quality integrated audio with 20Hz-20kHz frequency response and 4 hours of battery life.
The basic shape is elegant and strongly resembles traditional headphones. The familiar form factor makes it easy to carry around during travel, and it doesn’t draw nearly as much attention as other head mounted displays.
All it takes to immerse in a video is to move the lenses horizontally in front of eyes. Users can adjust for varying distances between eyes and use interchangeable nose pads to ensure great fit. The Glyph also accommodates for people with poor eyesight. This feature is necessary because it’s not recommended to keep a pair on while using the Glyph.


==Display==
'''Note: Avegant pivoted away from consumer headsets to focus on light field display technology for AR/automotive applications. The Glyph is no longer in production.'''
Instead of relying on traditional screens, the Glyph recreates natural sight with Avegant’s patented Retinal Imaging Technology, which uses advanced optics and microscopic mirrors to project images directly to the eyes.
Not only is this technology capable of producing high quality picture with vivid colors, but it’s also very safe and doesn’t cause eyestrain. That’s because the light source is a low-powered Light Emitting Diode (LED) that is combined with a micromirror array and optics to create a very comfortable image that feels natural even after longer periods of time.
The experience is like watching an 80-inch screen viewed 8 feet away, with enough space above and below to see waht’s goign on around in the real world.<ref>http://www.theverge.com/2015/12/15/10180320/avegant-glyph-personal-theater-headset-shipping-media-vr</ref>


==Audio==
== History and Development ==
The Glyph is equipped with a pair of 40mm high-performance polymer drivers. The over-the-ear design of the driver housing offers a good amount of passive noise isolation for comfortable listening during travel.
Audio can be played either via the built-in HDMI port or the 3.5mm connector.


==Charging==
=== Avegant Background ===
In video mode, the battery can last up to 4 hours. It takes about 3 hours to charge it to its maximum capacity. During this time, users can use the device in a regular fashion.
Company origins:
* Founded by Michigan University researchers
* Retinal imaging technology focus
* Kickstarter success
* Consumer electronics venture


==Usage and Compatibility==
=== Kickstarter Campaign ===
The Glyph is designed to work with content from multiple different sources, including smartphones, tables, laptops, consoles, media players, drones, and more. Users can download [https://avegant.com/set-up-support#resources a compatibility guide] for a comprehensive list of tested devices.
Crowdfunding success:
Currently, onboard head tracking allows the Glyph to work with the JauntVR player, and compatibility with additional players is expected to be added in a near future.
