LEGO Architecture meets BIM – Part 08: Augmented Reality
In the last post on this series on LEGO Architecture meets BIM we looked at how information can be displayed on drawings. In this post we look at how we can use Augmented Reality (AR for short) to view both the geometry of the model and also data.
Wikipedia explains that Augmented Reality “is a live direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data”. You will see from our example that the augmented reality displays the LEGO model directly on an iPad generated directly from a printed graphic.
Creating the App
In order to create this post we had assistance from Soluis Interact to create an Augmented Reality App which is available from the Apple App Store for Apple iPads.
The process involved working collaboratively to determine what was required, when it was required and agree the design and feel of the App.
The model was exported directly from GRAPHISOFT ARCHICAD as a series of .3DS files, one for each step of the sequence. We also provided Soluis with the data requirements for 5 pieces of the LEGO set.
The final look and functionality for an Augmented Reality App are totally flexible and we could for example have used the model to look at different colour options or even completely different design options. So what you see is just an example of how Augmented Reality can be used to share a model with others not the only way it can be used.
More information about Soluis is available at the bottom of this page.
LEGO Architecture meets Augmented Reality
Once you have downloaded the App and launched you will see the following screen below.
You can get to the trigger image, launch the model, connect to the entire blogs series on LEGO Architecture meets BIM or find our social media and email contact details.

Selecting ‘View Model’ will launch the trigger screen below. You need to make sure you have printed out the trigger image first. Once you have this just point your device at the image.

The model should now be visible if you point your device at the printed image. Initially you will only see a small part of the model. This initial step shows a few steps into the building of the LEGO model. The slider at the bottom of the App allows you to move through the build sequence. Simply swipe right to left to see the following steps.
Also remember that you can either move around the trigger image or rotate the printed image to see any angle of the model.

The App also contains a number of blue diamonds floating at various points. These diamonds are further triggers to display information about 5 example LEGO pieces. By clicking on any of the 5 diamonds you will see some selected data about each component. This isn’t all the data for each piece but a small sample to show how the data can be viewed in an Augmented Reality App.

Augmented Reality offers another opportunity to use a Building Information Model to communicate design as well as information to clients and other stakeholders. Its probably fair to say that there is a time and a place for using Augmented Reality but its definitely another tool in the armoury for those choosing to adopt BIM workflows.
