#MobCon Recap: HoloLens Goes East
Last month, I had the immense pleasure of flying to Sofia, Bulgaria, to speak at the MobCon conference, organized by MentorMate. It was my fourth time in Sofia, and I was looking forward to the trip. I know that there are a lot of passionate software developers and quite a few consulting firms in Bulgaria.
Deciding to speak at an event always depends on a number of factors, including whether I’ve spoken at the same conference before and, if so, whether I had an enjoyable experience, the topic the conference organizer is interested in, etc. In the case of MobCon, the decision was easy: I was to give a HoloLens presentation in a country where HoloLens is not very present yet, and I had never spoken at this conference. And what was really interesting: Most speakers at MobCon are from different communities and ecosystems—no Xamarin, no Microsoft, no Azure, and certainly no HoloLens. Speaking at MobCon would mean touching a new crowd, and bringing a different message to them, which is exactly what my job is all about.
My session, titled HoloLens 101: First Experiences With Holographic Computing, was quite short and focused (you can find all session materials here). I started by explaining the differences between virtual reality (VR), augmented reality (AR), and mixed reality (MR):
- VR: We can say that VR is a fully immersive experience (such as that offered by Oculus Rift, HTC Vive or simpler systems like Samsung Gear), where reality is re-created from scratch. In a VR experience, viewers do not see the “real world” around them, which can be exciting (brand new worlds!), but also disconcerting.
- AR: This can be as simple as a football game on TV with additional information such as who’s playing, the score, etc. On a phone, AR often takes advantage of the GPS, compass and accelerometer to map the real world and the virtual world, for example to superpose billboards of information above real buildings, etc.
- MR: Finally, what Microsoft refers to as mixed reality uses HoloLens spatial features to create and place holograms so that they can interact with the world around them. This creates a truly fascinating experience in which the "real world" is augmented by information that is tricking the brain into believing that it is real.
I then went on to show how the development environment works, and also had a demo showing the basics of Unity and scripting in the 3D space. Finally, a good third of my presentation was focused on live demos of the HoloLens device. I started with simple experiences, and moved on to applications developed by Valorem, most of which are available on the Windows store.
During my presentation, I reviewed real-life usage scenarios of HoloLens in the professional world. For example, we looked at our HoloTire point-of-sales app, which shows how a hologram of a tire can be presented to a potential buyer to explain some hidden features (such as the integrated sensor within the tire).
The chemical plant demo showed how a 3D model of a distillery unit can be inspected by a team in model size, and how they can interact with parts of it, for example, pipes and valves, checking for the parts’ properties and blueprints. In this demo, we can also enlarge the model to life-size dimensions and walk inside it, making sure that all the elements are at the right place.
Finally, we reviewed the HoloBeam technical preview, a telepresence application in which one person is filmed by a Kinect device (or other 3D cameras), and the resulting stream is broadcasted to a HoloLens device. The result is a real-time hologram of the broadcaster, something like 3D Skype if you wish. The application I demonstrated during my presentation was a recording but we can also use HoloBeam for live transmission.
The feeling during the talk was great, and the feedback I received from the audience was overwhelmingly positive. No doubt many people saw HoloLens in action for the first time and went back home knowing that they have seen the future. I hope I have inspired many to start new projects with this amazing technology. I came back from Sofia very excited to work with such advanced technologies, and to have the pleasure to share our experiences with others.
