Yesterday I was lucky enough to get a chance to try out the much vaunted Hololens, which is a completely new device from Microsoft which provides “Augmented Reality” as opposed to the Virtual Reality devices like Oculus Rift provides. The wording may be subtle, but the difference is quite large. Augmented reality projects objects into the actual room you are in, rather than moving you into an entirely different world like VR does.

Hololens is quite the device. It can track the physical space around you very well, and unlike VR, there is no requirement for markers in the room or extra cameras to track movement in the room. It is completely self-contained, and that may be one of its biggest wins of all.

The device on hand was near-final hardware, and the actual device looked exactly like what has been promised for some time. Although we did not get a chance to see the preview device in January, it was apparently nothing like what was presented at Build this week.

However just like January, we were not allowed to take any actual photos of the demonstration units, and all interaction with the device required us to lock our belongings in a locker before we could enter the room. They did however have a unit on display under glass for photo opportunities.

Let’s start with what they got right. Interacting with Hololens is very easy. There were only a couple of commands needed, and things like the air tap were very simple to use, and not once did I get a missed reading. That is extremely impressive considering it is just seeing my finger move in free space. When you want to interact with something, there is almost a cursor in the center of your field of view that you just focus onto an object. The object is then highlighted, and there will be no mistaking which object you are going to interact with.

Another interaction method was using a mouse, and when looking at a PC, you can simply drag the mouse off the display and the mouse cursor just moves into free space. In my demo, which was based on an architecture theme, this allowed me to interact with the model and move walls around, and change the design.

Another cool feature was the ability to leave virtual notes. Looking at a wall, I could see that someone had left me a note, and with a simple air tap I was able to hear what they had left. Then I could leave a note of my own on the wall for that person to see later.

Another win was the actual device itself. You put it on somewhat like a welding mask, and you just tighten the band on the back of your head with a wheel. Hopefully the durability of the devices is fairly robust, because we were helped out quite a bit to get the device on and off, but that kind of makes sense with the volume of people coming through the demo.

So what did it not deliver? The actual holograms had a very limited field of view. With the demos we had seen on the keynote, you could see holograms all around you, but the actual experience was nothing like that. Directly in front of you was a small box, and you could only see things in that box, which means that there is a lot of head turning to see what’s going on. On my construction demo they provided, I was supposed to look at a virtual “Richard” and I was asked if I see Richard. I did not. There was a bug with Richard and he was laying on the floor stuck through a wall. I understand these demos can have bugs, but it was very hard to find where he was with the limited field of view.

This demo is almost nothing like what you actually see in the device

The holograms themselves were very good, but they were so limited in scope that I can only hope that some work can be done there before the device goes for sale. There is a tremendous opportunity here and it would be awful for it to be spoiled by poor hardware. Although I didn’t get a chance to see the January demo, I’m told by several people who did that the field of view was a lot better on those units.

So my expectations were not met, and I can attribute that to the demos that were provided online and during the keynote. The actual experience was almost nothing like that, and what was shown on stage was amazing.

One thing that I wanted to know was what kind of hardware is inside, but there were zero answers to that right now. The device itself looked good, it felt good, the audio was good, but the main attraction still leaves a lot to be desired.

    I don't care for what any one of you have to say about this device.

    I just want to play minecraft on this thing.

    You'd be much better off with VR for a game like Minecraft. AR-like headsets are more for tabletop style games.

    So true, especially on the hardware side. I knew this was bunk when they claimed "it literally processes terabytes of data every second from it's sensors", right away you know it's all bs.
