Answers from the Microsoft HoloLens 2 Team Further questions on biometric security, audio and hand recording «HoloLens :: Next Reality



With the dust now finally settling for Microsoft's big announcement of HoloLens 2, the company is returning to provide more detailed details on some aspects of the device we do not know about yet.

Apart from a few team members The company is open to interviews and has launched a video streaming series that explores the intricacies of HoloLens 2, giving users and developers the opportunity to ask further questions. The first episode was aired on Tuesday and added some important details to the story of HoloLens 2.

The stream was hosted by Daniel Escudero, a senior technical designer at the Mixed Reality Academy, and Nick Klingensmith, a senior engineer for the Mixed Reality Academy, and Jesse McCullough, an experienced HoloLens developer who recently joined Microsoft as program manager Ecosystem Team for Microsoft's HoloLens has been discontinued.

Hand Tracking & Interface Interaction

Most first discussions were conducted I devoted myself in more detail to explaining what we already saw on stage as a demo, or in my case personally to the HoloLens 2 team on Mobile World Congress. For example, the hand tracking and manipulation of virtual objects on the HoloLens 2 is particularly impressive compared to the first HoloLens.

At one point, McCullough admits (and I agree): "There is one million wrong ways to listen for air [on the first HoloLens] and about three correct ways. " It's true that the various finger gestures required to interact with the first HoloLens were cumbersome and difficult for some to master. The new hand-tracking system is a huge leap forward, making controlling virtual objects a breeze as the system mirrors up to 25 compounds in the human hand, allowing you to perform various multi-hand interactions with amazing specificity.

During my test of Bei HoloLens 2, I put this hand to the test and did everything I could to make it fail, and it held up spectacularly. In Microsoft's new video stream, the team showed some animations that show exactly how virtual objects can be controlled with the HoloLens 2.

Benefits of the Noise Canceling Microphone and Biometric Safety Concerns

Another feature highlighted during the session was the device's noise-canceling microphone, which uses a five-channel microphone array. The microphone in HoloLens 2 allows the user to seamlessly speak commands that display text or trigger actions while interacting with your hands with virtual interfaces. This noise reduction feature is particularly critical for businesses using HoloLens 2 in a noisy factory floor or in a busy warehouse or manufacturing environment.

Old HoloLens Apps on HoloLens 2

As for those who want to port old HoloLens apps to the new HoloLens 2, the team also outlined how this can be achieved.

"[HoloLens 2] Do not run Hololens 1 app natively, as HoloLens 1 is built on an x86 [Intel processor] architecture and HoloLens 2 is ARM based. Anyone who has a HoloLens 1 app wants to run it on a HoloLens 2 will have to transition to a newer version of Unity, "said McCullough.

" We recommend starting with the implementation of MRTK v2 and then they have to compile for ARM. That will not only be the case. "To compile your own app for ARM, but if you have third-party libraries or your own libraries, you'll either need to compile them yourself or find an ARM-compatible version, then if you've done all three of these steps and have included all of them If you've overcome bugs, you can add the new interaction model. "

Azure Spatial Anchors Vs. Anchor Sharing / World Anchors

Finally, one of the key aspects of using HoloLens 2 in our new cloud-based world is the ability to share and work with persistent virtual content.

HoloLens developer Anchors Sharing, known to as the HoloLens developer, was able to save a World Anchor on one device and share it with another HoloLens user, provided insights into how the new system works Azure Spatial Anchors to facilitate sharing and working with persistent augmented reality content across the cloud ecosystem.

"With Azure Spatial Anchors, we've achieved a colon over [the previous anchor concept]making it a cloud-based service to which you can attach the same anchors, and it's cross-platform so you can use it on H OloLens, ARCore, ARKit and hopefully future platforms, "said McCullough.

"But you can do the same thing – you can place an object in a specific physical environment and ask that this data be remembered syncs with the cloud, and if somebody later comes with your app with another HoloLens app , you can pull that anchor down in depth and see what you left there, or if you come across a phone or tablet with ARKit or ARCore in your app the same thing. "

This is just the first session in a series of video streaming sessions that sheds more and more light End users and developers can get the most out of HoloLens 2, which is expected to hit the market later this year.
