IVAS eXPeriment

Thirty-five people took part in the Immersive Virtual Architecture Studio (IVAS) between 26th February and 9th March 2018. The experiment was simply presented as a room scale VR experience where you would have to solve a few jigsaw puzzles inside different rooms. This was one of the most important and exciting parts of my PhD research project. Follows a short explanation of context, purpose and approach.

Context

Homo Sapiens’ biggest achievement, to a certain extent, as a global civilization, has been to transform and adapt the environment to his needs. The main strength to achieve this outcome is Sapiens “spatial awareness”: the ability to perceive and make sense of his spatial environment and the intrinsic sense of agency that it affords. Sapiens developed this ability following different trait, the most recognizable one being known under the field of “architecture”. For more than five thousand years, using bricks and mortar, he built places to fulfill all the different functions required by society: services, religions, politics and other cultural activities. In the 21st century, Virtual Reality (VR), an inherently spatial technology, offers us the perfect medium to test and apply some architectural principles developed over the centuries to structure and navigate today’s overwhelming digital landscape.

Purpose

The built environment has a significant effect on humans behavior in the physical world (1). How does that translate in VR? The overall aim of this project is to establish the foundations of a framework to support the design of Immersive Virtual Environments. Such a framework will have benefits not only for scientists but in every field VR is disrupting such as game design, industrial design, data visualization and learning applications to name just a few.

Approach

This study is exploring ways to evaluate how different architectural elements affect human’s spatial cognition performance using the IVAS. The following steps will be to apply those findings to support specific cognitive tasks for specific users. This particular iteration of the project is looking at two architectural elements arranged following two spatial characteristics. Those fours conditions are tested using three cognitive tasks. Follows a short description of the setup.

Physical Space – Hardware – Mode of Interaction

For most of our history, natural movement has been the only way to navigate our environment and to experience “architecture”, therefore, it is the primary mode of interaction used in this experiment. To accompany this principle, a room-scale VR environment is set up with a minimum of 9 sqm (3mx3m) of navigable space. In this instance, the IVAS exp. happened in two different rooms, at two different sites: Goldsmiths, Hatcham house, 1 and Soapbox, Old Street 68.
The second mode of interaction is the VR system which is composed of an HTC Vive head-mounted display with two wireless hand-held controllers allowing together 18 degrees of freedom (18 DOF) of movement. The headset is tethered to a powerful laptop that runs the simulation.

Virtual Space – Software – 3D Models

The room with approximately the same dimensions as the physical room is modeled in 3D and will serve as the base for the different conditions (architectural scenes) that will be tested. All other 3D assets are modeled using 3Dsmax before being imported in Unity3D where the interactivity is programmed.

Spatial Conditions

Two architectural elements, wall and columns, were studied following two spatial characteristics: enclosure and complexity (3)

  • A1 : Close Columns
  • A2 : Open Columns
  • B1 : Close Walls
  • B2 : Open Walls

Three Tasks involving Spatial Cognition

Solving a Jigsaw Puzzle

This task was design to encourage participants to navigate the space in search for all the items needed to solve the puzzle. A stopwatch was encouraging them to do so as fast as possible – a way to measure performance. VR allows to easily track user’s movement: time, position and rotation. Everybody seems to have enjoyed solving the jigsaw puzzle and were very focused on the task. I had to remind them to explore the space before starting the task. Once the puzzle was solved, the participant was automatically transferred to a transition area where he had to rate two experiential qualities.

Rating of Experiential Qualities (REQ)

The spatial analysis can only be meaningful in regards to an equivalent evaluation from a human experience point of view. Evaluating “lived space” (2) can be done by asking participants to rate their experience with each spatial characteristics. This task brings the qualitative human evaluation into the equation. Using a semantic differential scaling technique, subjects were able to differentiate their appraisal using a five-step Likert-like scale. The rating categories were selected to represent previously mentioned properties: enclosure and complexity.

Perspective Taking Task (PTT)

Once out of the IVAS, participants had to answer a few questions on the online questionnaire before completing this last cognitive task. The main purpose of this task is to measure the memorability of each scene (4). It consists of a sequence of 16 pairs of images. For each pair, one of the images was taken from one of the explored room, the other image was taken from a room not visited. The participant had to identify which image relates to one of the scenes he had experienced.

Perspective Taking Task – Pair 11

Space Syntax Design Analysis

The design analysis using Space Syntax approach will give us an objective measure of each considered spatial characteristics. By combining both “Isovist” and “Visibility Graph” techniques, we obtain a number of measurands (3). In this case, we will be using the following measurands to represent the best predictor variables for the spatial characteristic considered:

The spatial qualities and their related measurands are :

  • Enclosure: “isovist openness” and “jaggedness”;
  • Complexity : “number of vertices”, “vertex density”, “roundness” and “jaggedness”;

Early Observations

A quick glance at the data shows that participants experienced spatial complexity as intended in the scenes designed with the columns. Their average best performance comes out of the scene with the closest room with columns. However, the feeling of openness doesn’t seem to be related to the number of windows in the room. One explanation for this is most probably because there was a texture on the glass. It wasn’t completely transparent. A participant even said: “I didn’t realize that there were glass panel walls!”
This is just a short intro of the kind of conclusions I am working on. This experiment is bringing plenty of good data to dig into, some with positive results some negatives. I have a few pages to fill with that discussion (check further posts).

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.

The ArchiMemory eXPeriment

This is where you will participate to an experiment that will show you how to improve your memory by using your spatial cognition. Before you enter the experiment, a short introduction.

Introduction
History is paved with mnemonic devices that makes use of our spatial ability to remember all sort of information. Our sense of space has evolve for thousands of years to become part of what makes us human. This project is looking at how architecture influences this ability? What features will help to build meaningful virtual spaces that will enhance the way we learn and memorise information?

To explore these questions, ArchiMemory propose a simple memory task: remembering a sequence of random playing cards. To do so the participant will train his spatial memory by navigating a 3D Virtual Environment. Like in a video game.

You don’t need to know more for now, you will be guided step by step.
