Glyph, a new Head Mounted Virtual Retinal Display by Avegant

A company called Avegant, a name that you might not heard of yet, has just announced a beta consumer concept of what the call a Virtual Retinal Display called Glyph. The Glyph headset integrates a brilliant, vivid video display and premium audio experience in a unique flip-down form factor looking just like a pair of headphones that double as a HMD. Prototypes of the Glyph Beta will be featured at the Consumer Electronics Show in Las Vegas from January 7-10, 2014. Consumer units will be available for purchase through a Kickstarter campaign that should start on January 22 and backing it up with $499 will secure you a kit that will ship later in the year.

Key to the innovative nature of Glyph is its optical engine called a Virtual Retinal Display (VRD). Using a low powered LED, a series of custom optics and a micromirror array, the visuals produced by the headset are supposedly crisper and brighter than those from conventional display technologies – think in the lines of using micro projectors that project the image directly on your retina. There will also be an integrated head tracking for more immersive and responsive gaming that should be compatible with all of the latest consoles and games according to Avegant and in order to achieve this you should most likely be able to map it to other controls. The shipped version will have one HDMI/MHL cable, onboard battery power and a thinner, narrower display band than the Glyph Beta shown at CES.

A Virtual Retinal Display uses a micromirror array and a combination of optics to reflect an image directly onto your retina, effectively using the back of your eyeball as a screen. The resulting picture is extremely sharp and vivid, unlike anything a conventional display can produce. In particular, the 3D images are exceptionally clear. The people that have tried the prototype from Avegant report that even though it had lower resolution of 1280×800 pixels the image quality looks really great and better than what a similar resolution HMD device using LCD displays can provide. You will also have an option to adjust the diopters in the Glyph to accommodate a wide variety of prescriptions and pupillary distances, so no need to wear prescription glasses while using it.

The Glyph is made to be media agnostic, meaning that it can plug into any HDMI source and display any current content natively. The beta headset will have one MHL/HDMI cable that will plug into any HDMI source and for the 3D is should be based around the HDMI 1.4 frame packaging format. According to Avegant the beta headset should have enough battery life to power a full-length feature film, or about two to three hours. The Glyph headset should have a 45 degree field of view, so this makes it more like an alternative solution to devices such as the Sony’s Personal 3D Viewers, Carl Zeiss Cinemizer or the Silicon MicroDisplay ST1080 than the Oculus Rift for example.

The idea and the technology seems very promising, and Avegant is reporting that many users who experience eye strain or nausea in looking at a conventional display feel no similar effect using this technology. The price also seems just about right and much lower than other higher priced solutions such as some of the HMD devices already mentioned aside from the Rift, but the Glyph will be a competitor for that device anyway. What bothers me a bit actually is the headset design that places the video part on the top of the headphones frame, meaning that if not used for video the optics will be sitting on top of your hair. The concept also shows no means to block external light are available, something that can kill a bit the sense of immersion at least for LCD-based HMD devices, it is possible that with this projection technology that might actually not be a problem, but it is something that needs to be checked. Anyway, I’ll be keeping an eye on the Glyph as more information becomes available about the device, and so should you if you are interested in VR and HMD devices.

BenQ With New 24-inch 3D-capable Monitors – XL2411Z and XL2420Z

Soon after the announcement of the new 27-inch BenQ XL2720Z 3D-capable monitor, the company has just announced two new 24-inch 3D-capable displays that essentially bring the new features of the larger model to the smaller 24-inch ones. The new BenQ XL2411Z and BenQ XL2420Z will probably replace the older XL2411T and XL2420T/TX series, but the not so good news is that these two new models expected early next year will not feature support for the new Nvidia G-Sync technology. Nvidia has promised us the G-Sync DIY upgrade modules before the end of the year, but we are still not seeing these available, and availability of models with G-Sync support built-in early next year, but it seems things may get delayed a bit. BenQ XL2411Z and XL2420Z are suppose to be available in early 2014 and probably not too long after their release on the market BenQ may also announce new series that are supposed to provide G-Sync support as well as the company is an Nvidia launch partner for the G-Sync technology.

Enough with G-Sync for now, the BenQ XL2720Z and the new smaller BenQ XL2420Z and XL2411Z monitors that will feature 3D Vision support with an external 3D Vision kit (including IR emitter as it is not built in) as well as 3D LightBoost technology. However, apart from the 3D LightBoost support (strobing backlight) these display feature a new Motion Blur Reduction technology developer by BenQ that is supposed to work in a similar way as the 3D Lightboost, however BenQ’s solution will be video card type independent and you will not need to “hack” it to work in 2D mode as well. Other interesting things about the new BenQ Z-series is a the addition of Low Blue Light mode that allows gamers to adjust the blue light levels of the monitor – what is considered to be the major cause of eyestrain when using computers for long periods of time. Another new feature introduced a these monitors is the Gaming-comfort Flicker-free technology that is supposed to eliminate noticeable flickering of the backlight when you lower the brightness level of the monitor (no PWM dimming of the backlight).

GameGradeVR, a Gamer Driven Ratings System for VR Drivers

December 9th, 2013 · No Comments · 3D / AR / VR / HMD

gamegradevr-logo

Our colleagues at MTBS3D just announced the release of GameGradeVR, a service very similar to the GameGrade3D, intended to help gamers rate game compatibility with the various VR drivers – TriDef Ignition, Vireio Perception, VorpX as well as native support, all of which support Oculus Rift, but some are not limited only to that 3D-capable HMD. The GameGradeVR submissions are only limited for true stereoscopic 3D support and if a game uses 2D+Depth, Virtual 3D or Z-Depth rendering to create the stereoscopic 3D effect rating for it should not be submitted. You need to be registered at MTBS3D in order to be able to submit ratings in the GameGradeVR and the good thing about this system is that it is completely user driven, meaning that a game or a VR driver that claims to provide great results and experience may not turn out to be rated as such by the actual users and the opposite can also be true. So check out the GameGradeVR if you are interested and do have in mind that it was just launched, so there are still not that many submissions and here you can help…
