Report from the VR World Congress 2017

Bristol was hosting this three days congress. What a good excuse to explore the West Coast of England. Loved it! How to report from such an big event pact of keynotes, talks, debates and demos about Virtual and Augmented Reality, interactive storytelling and immersive art, architecture visualisation and video game development, to name just a few of the field involved ? I will start with  the general trends, then some key points from the talks, to finish with what really got me hooked.

This event was a solid push from AMD. As far as I can remember, AMD had always an edge to better process 3D on his most known rival Intel. Well, it looks like they are still in the fight, but now to process VR wirelessly with their Nitero tech. And this is important because, being in a virtual environment is pretty cool, however, without any cable in our way, it will be much better.  Hololens has taken that mobility party from the start. They made quite a demo there, bringing forward the Mixed Reality concept. That being said, I am still not convinced with this small field of view and the basic interaction where you pinch things around.

SoReal in china

In the meantime, the big hype is around VR location-based experiences. Mk2 in Paris looks very neat, curating only high quality content and SoReal, a VR theme Park in China sounds epic. On a hardware note, I am curious to see what kind of headset the Chinese will bring on the market with their DeePoon!

Another main trend is the good old haptic feedback. They are working hard to bring the third sense into the game. We are not sure what shape it will take:  gloves, waves, arms, sensors,…but it was explore in every corner of the congress.

Most important is the effort given to produce high quality content. At this stage, only great content will bring VR to the mass.

Follows bullets points of my tweets and comments of the different talks I followed:

On Wednesday:

  • Vive and the Evolving Ecosystem of VR” with Graham Breen from HTC.
    HTC Vive – Haptic

    What’s next for Vive and his ecosystem evolution? Not much on the hardware side, a part of those haptic gloves shown there. They are focus on helping and promoting content creators with their Viveport platform and the ViveX accelerator.

  • Streaming VR/AR Content over the Web”  with Jamieson Brettle from Google. That’s where it get really exciting! AR/VR through the browser. He was telling about pretty good compression performances for cloud point 3D with Draco. For sound volumetric or spatial audio, they are using Opus with ambisonic compression.
  • “Ghost in the Shell VR – A deep Dive” with Sol Rogers from Rewind.
    He delivered a great talk about how he and his team made Ghost in the Shell. He gave no numbers and ask very nicely not to take a photo!

    That’s all I got from Ghost in the Shell
  • “The Importance of touch: Mid-air haptic feedback for VR & AR” with Tom Carter from Ultrahaptics.
    How cool is that, conducting emotions through mid air haptic feedback? Because, at the end, it is the sense of touch that makes things real.
  • Perception = Reality: Exploiting Perceptual Illusions for Design of Compelling AR & VR Interfaces” with Hrvoje Benko from Microsoft Research. Don’t try to be perfect. Use tricks and perception illusion.

Using perception illusion to extend the experience; Passive haptic; Perspective Projection Mapping;  The rubber hand effect revisited as Haptic Retargetting; Body warping and world warping are very promising technic that make you  believe you interacting with objects and that gives you this haptic feedback.

  • “Virtual Futures Track: The Ethics of VR Risks and Recommendations” with Michael Madar from University of Mainz
    • Why should we care?  Our environment influence our behaviour.
    • VR brings the illusions of place, embodiment and agency.
    • Beneficial vs manipulative in VR, tricky balance to make.
    • Are we going to create a rating system for VR experience?
    • “Users should be made aware that there is evidence that experience in VR can have a lasting influence on behaviour after leaving the virtual environment.”
    • Users should also be made aware that we do not yet know the effects of long-term immersion.”

On Thursday, I went to only one talk from the lovely blue hair Mary Kassin from Google who explained her day-to-day process. She prototypes a lot. Trial, user feedback and iteration make the most of her time. She also mentioned the Tango ready phone to play with AR.

Alright, this is all very exciting, full of ideas, however, what made the biggest impression on me was the couple of VR visualisation agencies showing off their architectural Immersive and Interactive walk-through made with Unreal engine.  With this very realistic real-time rendering, we are getting closer to eliminate the long hours of rendering time for still images for a full immersive experience in the early stage of the process.  That is happening right now!

Virtual Reality Immersion for Christmas.

Over Christmas, my son and I had the opportunity to play around with the HTC Vive. Straightforward to set up, you need at least 2 by 2 meters of free space to enjoy the full range of motion. Overall, that was a couple of weeks of awesomeness. Follows a few lines on the games and experiences we have tried out.
  • “The Lab”: After the tutorial, this is the first place from where you start and learn the trick of the trade of the Vive. The main thing is to get use to moving around by pointing, with one of the controller, a ray of light  on a virtual grid on the floor. Then, pressing the trigger will teleport you to the pointed location. I am not totally convince by this method. It still gives me a kind of thickness and definitely reduce the feeling of presence.

  • “Rec Room” : my son’s favorite. He  played in there for hours. The stranger thing in Rec Room is that you play with strangers; you talk to them like they are just in front of you in the room. Well in a way that’s where they are,  virtually next to you. Then you make a team and go playing a exciting paintball or football game, even though they actually are in another country.

  • Portal Stories: VR”:  love it, my personal favorite game. Really good adaptation of an already so clever and fun game. A perfect match for the HTC vive. In one sentence, the game is about getting out of a room to the next. It is all about the room. Your living room suddenly develop an infinite potential.

  • “Irrational Exuberance: Prologue” : this introduction to a new kind of experience is really well design with subtlety. It starts from a very dark environment with just the title and some strange sphere of energy in your hands. They are encouraging you to use those to follow the sphere that goes along the title itself. Then you start to perceive some pieces of stone floating around. Instinctively, you want to push them away, then they break in smaller pieces. Doing the same movement a bit further, at some point you will hit something bigger which will break as well to bring you a glimpse of the outer space. This is the actual wall that surrounds you. By break the wall, you realise that you are standing inside a meteorite. The experience is very immersive, and taking you to a place you couldn’t have imagine. We want to see more of that!

  •  “Google Earth VR” :  bring you as a giant on earth. It is a fantastic feeling to be able to jump from one city to the next. I loved landing effortlessly at the top of the world on Mount Everest

  •  “Engage” is a Educational Virtual Learning Platform. That is where I get very exited. That is the core of my research project: how can we use this amazing technology to enhance the learning experience, to change education for ever?

We tried a few other applications as well like this architectural walkthrough “Bund88” which was not easy to load up probably due to the very quality of the render. However, the experience was so realistic. This is definitely a game changer for the architecture and real estate industry. The Roller coaster just made me sick, no comment. No problem for my son though.

The HTC vive is just one more convincing step towards the development of a new medium with a huge potential not only for entertaining  but more for learning and sharing new skills and knowledge between people all over the world.

I was in those virtual worlds more than two weeks ago and still, I can close my eyes and vividly remember the different environments and interactions I lived then as it was this morning.  We learn through experience. That is what VR is all about. We are barely scratching the surface of this new tool that has the potential to positively impact the world.

VR or 360 panoramas apps for sharing?

Have you tried any of those Virtual Reality (VR) headset yet? Did you enjoy looking around being immerse into a totally different environment. Have you even had the opportunity to move around and interact with some object or even other avatar?

Actually, you can even create your own VR environment quite easily. Although, it depends on the level of “realism” you would like to achieve: you can upload panoramic photos or video of your physical environment, which will be realistic visually but not very immersive because of the lack of interaction or you can upload your own 3D environments fully programmable.

As an architect, I was  looking for a 3D VR application that would allow me to share an experience of the project I was working on online with the other architects and designers or even with the client.

I have tried a few of those applications, here are my findings. The best option, from a budget and mobility point of view, these days is to opt for a format that can be “experienced” with a smartphone and a google cardboard style headset. Another option, much more expensive,  is to choose the heavier solution using a head mounted display linked to a powerful computer, not as convenient but brings more immersivity. Today’s post will focus on the former.

Considering buying a VR headset is a bit of a hassle; so many option out there.  Basically, any cheap Google cardboard style headset  is good enough. The one I picked up is the MergeVR: using soft material, it is more comfy and it offers buttons to interact with the VR environment. It fits easily any size of smartphone. It works wonders with my LG G5.

That aside, back to the software. After having modelled the whole project in details, instead of having to render dozen of stills from all the angles, I thought a VR experience would be a better solution to immerse the client in his project. Two main choices from there: either you want to walk around inside the 3d model, or you render 360 images that let you look around from a fix location. I tried both, not able to share much without giving my login I am afraid. Here is what I found:

  • InVR : Easy to upload any 3D model. Can be straight from inside Unity through a plugin or via an FBX upload. The mobile app is ok, no sharing yet.
  • Iris: divide into two :
    • Iris Scope for 360 panoramas accessible via smartphone/cardboards. The  app is neat and quite professional. That is the one I used to show to the client. No sharing though.
    • Iris Prospect to share 3D model like obj, sketchup or Revit, although for those, you will need Oculus or HTC Vive.
  • Roundme: 360 panorama online made easy. This is more for everyone uploading their photos. Probably the most user friendly  for sharing 3D 360 panoramas. Check this sample that I upload there when working on this Saydnaya prison project.

  • WebGl: which is actually the option we develop for the final project. Saydnaya prison. However, we didn’t had enough time to develop the whole VR environment. It is “only” 360 Interactive Panoramas you can access from a desktop/laptop web browser.

There are of course some other apps on the market. The one mention above are working on Android. Let me know if you find anything else worth mentioning.

Happy VR.
