Microsoft, that comes with a vision that is grounded with both, the world that we live in today and that we strive to create in the time to come has always led the way whenever it has come to innovation in technology and more.

And Microsoft's Holographic Augmented Reality Headset named HoloLens, believes that it can transform the way we learn, work and play. It was one device that took everyone by surprise when it unveiled itself in the beginning of 2015 at a Windows 10 event.

The HoloLens headset, a revolutionary device, being a bold piece of hardware was the first sign that Microsoft was now taking AR and VR seriously and in fact is known to be the first holographic computer that is self-contained and that also enabled its users to engage with the digital content and to interact with holograms in the world that is around them.

They are simply a pair of goggles, that fill the world around you with 3D holograms and convince you enough to make you believe that they're actually real and in front of you. It all sounds like the very similar tech company promises that we've all heard before, but HoloLens is definitely something very real. Using this Microsoft device proves to be an experience that is quite unlike any other.

But, no matter how many features it came with and how incredible it looked pre-launch, one issue that was the with the Microsoft HoloLens, and that took it back, dulling it all over was its limited field of view that made it hard to keep up the experience that was promised as even a little movement would make the holograms slip out of existence. And it can be very distracting to see the objects in the real world keep disappearing. It is almost like you are just staring at a screen as the restrictive FOV doesn't make for an immersive experience.

The HoloLens field of view is likely believed to be the limitation of the device's processing power. Unlike the most of the full-spec VR systems like today's Oculus Rift or The HTC Vive, the HoloLens is one device that is not connected to a host PC and that simply means you're less constrained to wander around like it was with the Vive or even stuck in a chair as with the Rift for that matter. It was hoped that as future versions of the HoloLens will be released by Microsoft, an increase in the processing power will cause the widening of the field of view.

Among the nuances of the problem, waveguide seemed to one as well. A waveguide points light in a certain direction, through reflective, rectangular tubes and In order to support internal reflections inside that waveguide, Microsoft had to limit the exit angle to 35 degrees, which impacted the field of view. So, now Microsoft split the image, projected the two separate components and then combined them, a method, based on the patents that were filed in April with the World Intellectual Property Organization and were discovered via MSPoweruser.

The Microsoft's optical engineers named Tuomas Vallius and Jani Tervo were able to achieve 70 degrees Field of view at the very least for the current HoloLens, with the individual components being able to support 35 degrees each as mentioned before. With a proper design, its inventors believe that a diagonal Field Of View of up to 90-degrees can be possible as well.

Thanks to the internal research, that Microsoft finally found a way to populate the world around us with 3D holograms by Doubling its Field of view and is to also publish a patent that describes the system.

Crucially, the technology has been tested on hardware already, that simply means that it could make its way into the next iteration of the device. The question that now arises is that whether 70 or even 90 degrees, will it still be enough?

Despite this, it’s still a big step towards the HoloLens development and is indeed a very welcomed news as it is always great to hear about some positive progress.
