Avegant Glyph Review – Mobile Personal Theater with Virtual retinal Display


Created by Ann Arbor, Michigan-based Avegant – The Glyph is a virtual retinal display that provides you experience of viewing an 80-inch, high-definition TV screen.

Forget screen sizes – whether big, small or second screen – as Avegant‘s Glyph will create visuals that don’t require a screen – only your retinas and your brain. This device has the size of standard studio headphones, and uses a special flip-down form factor to bring the personal theater in front of the user’s eyes. The Glyph is a wearable headset that can be used to play video games, watch 2D and 3D videos, and listen to music. Moreover, Avegant is even planning to include head-tracking capabilities in future versions in order that the Glyph can be used for 360-degree immersive experiences. The Glyph is the newest in a complete series of innovative human-machine interfaces – from virtual reality goggles to eye-tracking – that assure to turn traditional gaming upside down.

Avegant Glyph

The Glyph – which retails at $499 – is anticipated as mobile ear and eye display headgear, to be used for games, movies, and whatever else that requires a display. It has Bluetooth head-tracking technology that can be set to use for future VR-type applications. The device fits over your eyes like a large pair of electronics-filled glasses and projects pictures directly onto your retinas. The Diopters in the device can be adjusted to a broad range of prescriptions (+2 to -6) and Pupillary distances, so you will not necessitate your glasses. Note that this model doesn’t support astigmatic eyesight.

Glyph is a head-mounted virtual display just like Oculus Rift and its predecessors in a number of ways, but hugely diverse in some major areas. Compared to any VR headset we’ve seen yet, the way in which Glyph produces images is wholly different. Instead of depending on a set of high-resolution LCD displays placed near to your eyes, Avegant’s technology cuts out the middleman and makes use of a “virtual retinal display” to beam images directly onto your retinas. Delivering images directly into your eyeballs like this will eradicate the dreaded “screen door effect” that takes place when you put a screen near to your face, also significantly lessens eye strain.


The Glyph uses an HDMI input to display anything from your content library like movies that you own or Netflix movies that are streamed through your mobile device. What’s more, you can use Glyph for gaming with a PlayStation or Xbox console. The reflected light created from the device is very comfortable and natural sensation. Users, who have eye strain or nausea by staring at a conventional display, experience no similar effect with this technology. The beta headset will have battery life of around three hours, which is sufficient to power a full-length feature film.

Glyph: A Mobile Personal Theater With Built In Premium Audio

Avegant had launched a Kickstarter campaign last month, in just few hours, their campaign had already surpassed the $250,000 funding goal. Kickstarter campaign started on January 22 and runs through February 21. The company is planning to ship units to donors by the end of the year, and the beta device is predicted to be thinner and lighter than their already-evolved alpha model, mainly the earpieces which they want to decrease in thickness by 50%. Avegant is based in the heart of Michigan’s manufacturing area and expects to produce the Glyph as much as probable in the United States.
