The launch of Microsoft HoloLens gave birth to a revolution in the field of augmented reality in 2016. It was a “never thought before” concept that was designed and contained in a handy self-powered computer. It gives users an augmented or mixed reality experience that makes interactive augmentations so realistic like they exist in the real world.

Though it provides an amazing experience, the HoloLens headset has an extremely limited field of vision. So, viewing through the device is like seeing through a window into an augmented version of reality and not all around you.

Three years later, Microsoft launched HoloLens 2 with more features, functions and capabilities. This made HoloLens application development more convenient for the developers working in the field of augmented reality. Microsoft HoloLens 2 is an amazing hardware upgrade with greater comfort for front-line workers. Compared to its predecessor, HoloLens 2 has more computing power, better sensors, longer battery life and much more.

Some of the primary benefits of upgrading app to HoloLens 2

Ergonomic design

Where HoloLens 1 is not very comfortable for its users to wear for a long time due to its non-adjustable structure, HoloLens 2 takes care of the center of gravity to fit all shapes and sizes of human heads. The new design is sleek, three times more comfortable and lightweight. Another feature is its front visor that flips up due to which users don’t always have to take it off completely, every time they have to look outside the device.

2X field of view

The new HoloLens 2 has got a bigger field of view (FOV). This helps users to see more information and makes it more efficient. It almost has twice the field of view than the HoloLens 1. So, in place of 30 degrees, HoloLens 2 gives 52 degrees, which makes a huge difference in the way users see augmented reality through the device.

Hand tracking and gestures

HoloLens 2 is designed to give better hand tracking and gesture control. It has new, more intuitive hand gestures, for easier content manipulation. When a user touches an AR object, it generates a sound which makes it more engaging, enjoyable, interactive and realistic. The user can run commands using a combination of their hand movement along with voice control.


The HoloLens 2 is equipped with two cameras that track the user’s eye and detect the object at which the user is looking to provide a better interactive experience.


There is a big difference in the cost of HoloLens 2 from that of HoloLens 1. Where the cost of HoloLens 1 is high and differs for the developer edition and the enterprise edition, the HoloLens 2 device is available at the same price for all and is 1.5 times lesser than the cost of HoloLens 1 which makes it less expensive and affordable for more people.

The AR and VR headset market will reach 65.9 million units by 2022.– IDC

How to upgrade your app to leverage these amazing features of HoloLens 2

There are certain requirements that need to be taken care of before you proceed for HoloLens 2 app migration, such as:

I. Install the tools

Before you build your app, you need to equip yourself with all the tools that are needed to build applications for Microsoft HoloLens and Windows Mixed Reality immersive (VR) headsets.

Installation checklist:

Windows 10
Install the recent version of Windows 10 to match your PC’s operating system with the platform you’re building a mixed reality application for.

Visual studio
Install a fully-featured integrated development environment (IDE) for Windows. Use Visual Studio for writing code, debugging, testing and deployment.

Windows 10 SDK
This provides the latest headers, libraries, metadata and tools that are required for building Windows 10 apps on HoloLens 2.

HoloLens 2 Emulator and HoloLens Emulator
You can run applications on a HoloLens virtual machine image without a physical HoloLens using the emulator.

II. Choose your engine

1. Download the latest version
It is advisable to download the latest version of the Unity LTS (Long Term Support) stream to pick up the latest stability fixes.

2. Import Mixed Reality Toolkit (MRTK)
Mixed Reality Toolkit is an open-source, cross-platform development kit for the development of mixed reality applications. MRTK provides foundational components, a cross-platform input system and common building blocks for 3D interactions. MRTK accelerates the development of applications built for Microsoft HoloLens, Windows Mixed Reality immersive (VR) headsets, etc.

3.PC set up for upgrading mixed reality app
The Windows 10 SDK is the best option for the Windows 10 operating system. It is also supported on:

  • Windows 8.1
  • Windows 8
  • Windows 7
  • Windows Server 2012
  • Windows Server 2008 R2

The new HoloLens 2 device also has improvements like:

  • Multiple logins for the same device, making it easier to share in the workplace.
  • Enables to copy files to and from the device through Media Transport Protocol (MTP) support.
  • It is easy to manage and configure with improved Master Data Management (MDM) features.
  • Streamlines interactions with holographic objects.
  • New APIs that allow the animation of holographic app launchers.
  • Provides access to a galore of raw data from the sensors with research mode.
  • New protocols that make the sharing of 3D objects easy from a website, etc.


The HoloLens 2 device is an advanced and upgraded version of its predecessor. It is very important to have proper knowledge of the hardware and software if you’re planning for HoloLens 2 app upgrade. Though ample information is available online regarding the development of applications for HoloLens 2, successful development requires excellent knowledge and experience.

Hence, it is advisable that you hire experts from a HoloLens app development company for a successful upgrade/development of your existing/new application. This would save you time and speed up the development process. To know more about how to upgrade your app for HoloLens 2, get in touch with our experts.
