⚡️First impressions of my HoloLens

I am now proud owner of a HoloLens. I am not officially trained up on it yet as a Microsoft Employee. But I wanted to share the first impressions of setting it up and using it.

These are my personal impressions and not an official stance by my company. I’m sharing my first excitement here. I hope can make some people understand what is happening here.

This is also just a user POV as I haven’t started developing for it yet, but this will happen soon – promised.

HoloLens is unique

First of all, it is important to understand that HoloLens is something pretty unique. Every time I mention it people start making comparisons to the Occulus or Vive, but those don’t work.

A high-powered, multi camera mobile on your head

HoloLens is a self-contained computer you wear on your head. You don’t need anything else. It is not a peripheral, there is no other computer or server necessary. This is important when considering the price. Many VR headsets are much cheaper, but they aren’t Mixed Reality and they need a hefty computer to run. It doesn’t even need an internet connection all the time. Just because you wear them on your head doesn’t mean you can compare these products on even ground.

You should plan coding for it like a mobile phone on your head in terms of CPU/GPU power. The specs are high, but the demand of the way it works are, too. If you build for HoloLens be conservative with the resources you need – you’ll make me happy. Waiting isn’t fun, even when it is a floating animation in your room.

Your natural movement is an event

HoloLens is a system that uses natural motion of your head and body to explore an augmented space. This means you don’t lose connection to the real world – you still see it through the device. What you get is a constant analysis of your surroundings and Holograms overlayed on it. You open apps and either use them floating before you or dock them to a wall to use later when you look at said wall. You distribute your work space in your living space – without needing to go to IKEA to buy furniture.

This means the way you move and where you look become events software can interact with. The “gaze” gesture, which is “looking at something” is akin to a hover with a mouse. The “air tap” gesture is a click or submit.

That way the relative small size of you viewport compared to Occulus or Vive is less relevant. You’re not stuck in it as your viewport follows your head movement. You’re not supposed to have a whole takeover. HoloLens is there to augment the world – not replace it.

Your whole body is now an event trigger. Instead of learning keyboard shortcuts, you learn gestures. Or you can use your voice.

Gestures vs. Voice Recognition

You can use your hands to select and interact with things. Or you can say “select” to interact and “next” to move on in menus. Voice recognition is always on and Cortana is just one “Hey Cortana” away. You can use it to open apps, search the web, research, all kind of things. It still feels odd to me to talk to my phone. I am on Android, maybe Siri is a better experience. It feels more natural to talk to a voice in a space of apps I distributed around my house.

Spatial sound

HoloLens has a lot of speakers built in which allows you to hear sounds from all directions. This is pretty amazing when it comes to games like RoboRaid:

And even more so in Fragments:

When using the speakers, there is not much privacy though. It is pretty easy to hear what HoloLens says when you are close to someone wearing it.

If you want a keyboard, you can have one

If you enter a lot of text into web sites or something similar, you can also pair a bluetooth keyboard. Or clicker, or whatever. At first it annoyed me to enter my pretty secure passwords in a floating keyboard. But the more I got used to HoloLens interaction, the easier it became.

A whole new way of interaction

I’m not a big fan of VR because I am prone to get nauseous if the frame rate isn’t perfect. I am also getting car sick a lot, so it isn’t something to look forward to. I also feel confined by it – it fills me with dread missing out on things around me whilst being in a virtual space. I don’t like blindfolds and earplugs either.

The only discomfort I felt from HoloLens is having something weighing close to a kilogram on your head. But you get used to it. At the beginning you will also feel your fingers cramp up during air tapping and your shoulders hurt. This means you are doing it wrong. The more natural you move, the easier it is for HoloLens to understand you. An air tap doesn’t need full movement. Consider lifting your finger and pointing at stuff. Just like interrupting a meeting.

An outstanding onboarding experience

What made me go “wow” was the way you set up and start working with the HoloLens. The team did an incredible job there. The same way Apple did a great job getting people used to using a touch device back when the iPhone came out. Setting up a HoloLens is an experience of discovery.

You put on the device and a friendly “hello” appears with Cortana’s voice telling you what to do. You get to set up the device to your needs by calibrating it to your eyes. Cortana tells you step by step how to use the gestures you need to find your way around. Each step is full of friendly “well done” messages. When you get stuck, the system tells you flat out not to worry and come back to it later. It is an enjoyable learning experience.

How I use it

Putting cat Holograms on the dog

Right now, I have my kitchen cupboards as my work benches. Edge is on one of them and next to it is my task list of the day. I have a few games on the other side of the room. When it comes to Holograms, there is a cat on our dog’s bowl and a Unicorn above the bed to give us nice dreams. Because we can.

Skype is pretty amazing on HoloLens:

Some niggles I have

It is important to remember a few things about the HoloLens:

  • It isn’t a consumer device but for now a B2B tool. On the one side there is the high price. And there is a focus on working with it rather than playing games.
  • It is not an outside device. HoloLens scans your environment and turns it into meshes. After it created the meshes it stores them in “spaces” avoiding the need to keep scanning. Outside this means a constant re-evaluating of the space. This is expensive and not worth-while. So there is no danger of a re-emergence of the annoying Google Glass people in the street. It stilll is disconcerning to look at someone not knowing if they film you or not.
  • I agree with a lot of other people that there should be a way to have several user accounts with stored calibration info on a single HoloLens. Whilst you can share experiences with other HoloLens users, it would be great to hand it over without recalibration and giving someone else access to my Windows account.
  • There should be a way to wipe all the Holograms in a space with a single command. When you let other people play with your device you end up with lots of tigers, spacemen and all kind of other things in your space that you need to delete by hand.
  • Whilst it is easy to shoot video and take pictures of your experience, the sharing experience is very basic. You can store it to OneDrive or Facebook. No option to mail it or to add Twitter. That said, Skype helps with that.

This is truly some next level experience

I am sure that there are great things to come in the VR/AR/MR space. Many experiences might be much more detailed and Hi-Fi. Yet, I am blown away by the usefulness of this device. I see partners and companies already use it to plan architectural projects. I see how people repair devices in the field with Skype instructions from the office. I get flashbacks to Star Trek’s Holodeck – something I loved as a teen.

It is pretty damn compelling to be able to use your physical space as a digital canvas. You don’t have to leave your flat. And you don’t run the danger of bumping into things while you are off into cyberspace. It is augmentation as it should be. In a few years I will probably chuckle at this post when my cyber contacts and ear piece do the same thing for me. But for now, I am happy I had the chance to try this out.
