Now that we have officially seen HoloLens 2 and Microsoft have shown improvements and new superpowers in the magnified reality head, how about the specifications?
Fortunately, Microsoft has laid the full specifications for its next-generation headset. Let's dive in and see what $ 3,500 buys.
- Optics: Transparent holographic lenses (waveguides)
- Resolution: 2k 3: 2 light engines
- Holographic density: > 2.5k radiation (light points per radian )
- Eye-based rendering: Display optimization for 3D eye position
The display is probably the most important aspect of all magnified reality heads. One of the biggest critics of the original HoloLens was its limited viewpoint of about 35 degrees. For the sequel, Microsoft has succeeded more than double the field of view while maintaining image fidelity at 47 pixels per display.
During the presentation at MWC, Alex Kipman, Microsoft's technical associate and chief honcho at HoloLens noted that HoloLens 2 uses a microelectromechanical (MEMS) laser scanner to achieve the wider field of view, a fact suggested by a patent application published by the US Patent and Trademark Office in June and submitted by Microsoft in December 2016.
- Depth: Azure Kinect Sensor (Deep Camera: 1MP Flight Time; RGB Camera: 12MP CMOS Sensor Roller Shutter)
- IMU: Accelerometer, Gyroscope, Magnetometer
- Camera: 8MP still images, 1080p 30fps video
- Microphone array: 5 channels
- Speakers: Built-in spatial sound
The secret sauce behind the improved user Experience for the HoloLens 2 is ] The Azure Kinect sensor, which is also available as a stand-alone unit . According to the sensor specifications, the Azure Kinect includes a 1MP sensor and a 12MP rolling door ROS camera CMOS sensor.
The headset also includes sensors that could be found in modern smartphones, including a camera for capturing 8MP stills and 1080p 30fps video as well as an inertia meter containing an accelerometer, gyroscope and magnetometer to determine the device's orientation and motion within an environment .
On the sound side, HoloLens 2 contains a five channel microphone set for voice input and recording, and built-in speakers for spatial sound.
- Hand Tracking: Two-handed sloping model, direct manipulation  Eye tracking: Real-time tracking
- Voice: Command and control on the device, Natural language with Internet connection
With the improved depth sensor, HoloLens 2 can move beyond preset hand hold and track the user's hand movements with greater accuracy. This allows users to interact directly with 3D content with more natural gestures. Eye tracking adds another layer of user input, allowing users to browse web pages with their eyes and verify their ID using Windows Hello.
- 6DoF Tracking: World Scale Position Tracking
- Spatial Mapping: Real Time Metering Network
- Mixed Reality Caption: Mixed Holograms and Physical Environmental Scenes and Videos
Azure Kinect also plays a role in improved tracking and real-time construction. We have seen improved speed and range of the sensor shown earlier, the improvements here are not so shocking.
Calculate and connect
- SoC (system on a chip): Qualcomm Snapdragon 850 Compute Platform
- HPU: 2nd Generation Custom Holographic Processor
- Wi-Fi: 802.11ac 2×2
- Bluetooth: 5.0
- USB: USB Type-C
Snapdragon 850 processor is the same in Windows 10 laptops and has a CPU clock speed up to 2.96 gHz. Microsoft has also equipped HoloLens 2 with an improved holographic process unit. The included Wi-Fi, Bluetooth 5.0 and USB-C are standard, but it is a pity that Bluetooth 5.1 does not specify the location.
- Battery Life: 2 to 3 Hours Active Use
- Charging: USB Power Supply Charging)
- Thermals: Passive Chilled
For a device aimed at business users, the battery life of up to three hours during active use can be a little worrying. However, the fast charging function works to compensate for the weakness. In the case of thermal products, Microsoft designed a new steam chamber for passive cooling.
- Size: Single size adjusting screw
- Recipe lens: Fits standard eyeglasses  Microsoft made much of the comfort improvements during the MWC presentation. Constructed of a lightweight carbon fiber, the unit is more balanced to accommodate the user movement. The company also scanned the head of a wide range of human subjects so that the design could provide a comfortable fit for almost everyone.
While Magic Leap One comes in two versions to accommodate different head sizes, HoloLens 2 comes in one size with an adjustment knob. There is no special mounting required for the new HoloLens either. Also, unlike Magic Leap One, HoloLens 2 fits over glasses, so there is no need to worry about buying a prescription.
- Windows Holographic OS
- ] Remote Assist
- 3D Viewer
- OneDrive for Business
As you expect, HoloLens 2 runs on a version of Windows intended for the headset, with Edge as web browser and OneDrive for Business is facing cloud storage and collaboration. The device will also include Microsoft's existing HoloLens apps, namely the 3D viewer and a couple of company apps, Remote Assist and Layout, along with a new app called Guides to cover training and workflow management.
Of course, as those who follow the tech world know, the specs don't mean everything. Software and hardware integration determines whether the device can utilize these specifications.
