Microsoft HoloLens 2 works with lasers for larger field of view and costs $ 3500

Microsoft has announced the HoloLens 2. The headset has a Snapdragon 850-soc and uses lasers and mirrors to create images. As a result, the field of view is much larger than with the first version of the HoloLens.

The limited field of view of the first HoloLens was seen as a major drawback and Microsoft resolves that with the new version by using a different technology for displaying the images. The HoloLens 2 works with lasers that shine lightly in two oscillating mirrors. Those mirrors move so fast that they can, as it were, paint the image on the screen. The images are projected onto the waveguides , which are the pieces of glass that are in front of the eyes of the wearer of the headset.

The HoloLens 2 would have a field of view that is twice as large as that of the first version. According to a hands-on by The Verge , the image does not yet take the entire field of view of your eyes, but it is now so large that it is no longer annoyingly small. Microsoft speaks of a 2k resolution per eye and lasers could project images with a brightness of 500 nits.

Microsoft uses a new Azure Kinect sensor for depth measurement. That is a camera on the front of the headset that recognizes objects and makes a scan of them. For example, the user’s hands are continuously monitored and the HoloLens 2 recognizes gestures such as something grabbing or pressing a button. In this way, users can interact with virtual elements. The headset also has eyetracking and speech recognition built into it.

All hardware is in the back part of the headset. That should make the wearing of the headset comfortable due to the distribution of the weight. At the back is a dial to lock the headset and once users have it on, they can fold the visor up if they do not use it.

Microsoft provides the HoloLens 2 with a Snapdragon 850-soc, combined with a custom holograhic processing unit of the second generation. The whole is passively cooled and the battery would be good for two to three hours of use. Charging is via a usb-c connection.

The HoloLens 2 is intended for companies and can for example be used by designers and engineers. Microsoft does not target consumers with the headset. Later this year the headset comes out for $ 3500. A euro price has not yet been announced. The headset initially does not come to the Benelux, but will be available in a number of other European countries, including Germany and the United Kingdom.
