D'Arcy with the novel over here :P

I'll add on a few things.

From the XR10 side, weight was even more of a challenge, given that it's strapped to a hardhat which already has weight and rides high on the head. What we've found through our research is that, while weight is important, it's actually weight distribution that people notice the most. Think about a motorcycle helmet that's 3x as heavy as a HoloLens, but it's center of gravity is in the middle of your head so you don't notice it much. The hardhat we made for HL1 was pretty front-heavy and made you feel like a toddler with undeveloped neck muscles. We focused a lot of energy on distribution for the 2nd generation and think we got it about as close to perfect as we could, given the hardhat compliance limitations of OSHA and the like...

We have lots of customers who tether a battery pack and run the cord into their reflective safety vest, getting a full day's use out of the device. Personally, I think that batteries are the #1 source for potential breakthrough in the next decade. They're the bottleneck in so many places.

Great question. The HoloLens 2 is a completely self-contained Windows 10 computer. It doesn't require any tethering (wired or wireless) to any external source. With that said, you can use cloud computing on HoloLens to enhance the capabilities of the device. As an example, check out 'Azure Remote Rendering'. ARR offloads all of the rendering to the cloud and makes the amount of data (e.g. number of polygons) you can load on a HoloLens near limitless.

If you go to this page and scroll down about halfway you'll see a button that says 'Show all tech specs'. That will give you the details on the processors, RAM, etc.

It's really unbelievable what it's capable of today and with (next to) no lag/latency on a device that's streaming 60 FPS. This video that my colleague Rene posted shows it in action running an 18 million polygon model (versus the onboard compute being able to render 500k-1m).

hey now...

There are a few different mechanisms to achieve this.

A user can connect to their HoloLens over IP in their web browser. There's a tab in there that lets you live stream in the browser. You can then just HDMI to a monitor or projector. This method works pretty well but is at the mercy of your WiFi network and what other traffic is going across it at any given time.

Our preferred method is using one of these guys. Plugs directly into the HDMI port on a monitor/TV/projector and creates its own WiFi network that you can connect the HoloLens to. You can do the same thing (direct wireless connection) on Surface.

If you have remote users you want to collaborate with you can do one of the above + a Zoom/Teams call with screenshare. You can also use something like Dynamics 365 Remote Assist to have a remote user "see through your eyes" to see what you're working on or help you through a task.
