Our review from Hololens 2 👓👷

During the 2019 Mobile World Congress, Microsoft shock the whole world with the presentation of the latest Hololens 2. This new model, better at its predecessor at everything is already in our hands. We have started to develop amazing projects with them.

The principal changes from this headset are based on the comfortability and immersion capacity.

Also, a new adjustment system is being added for its comfortable and prolonged use. Also, they are much more compact, and they have a hinge in the superior part of the helmet that makes possible change tasks with having to remove the glasses.

 

 

The FOV it’s been raised double, which moves the resolution from 720p to 4K. All these details make the user appreciate the text in a better and more comfortable way, especially with complex details.

This model disposes of Iris recognition, which allows starting the session in Windows hello and tracking the eyes moves to interact with the environment through the eyepiece. Its also capable of recognizing up to 25 joints from the hands, which allows interacting with more virtual objects without needing gloves.

In terms of the hardware, two are the most relevant news. This time Microsoft has chosen an ARM processor, 850 Qualcomm, one of the most powerful ones in the market, which will make this headset more power-efficient than its previous version. Finally, it has incorporated an Azure Kinnect sensor that will simplify the depth detection and space as well as the usage of Azure services.

 

 

Two kinds of headsets were presented in 2019, the standard version and one done specifically for the industrial environment: The model Trimble XR10, at Idiwork have this model with an integrated helmet homologated for industrial and safety environments.

 

The Hololens 2 is focused on industrial environments a,d a right decision from Microsoft. It has great expectations compared to its competitor: Magic Leap.
