Creating Augmented Reality Cards with Unity and ARToolkit – Zenva
This first tutorial on augmented reality AR will cover the basics of making a personalised digital birthday card. You can download all of the files associated with this tutorial from here. AR is the process of putting digital content images, videos, 3D models, … on top of your surroundings seen through a device such as a computer or mobile phone for example. What it basically does is use a camera as input and augment the stream from it with content not available in real life.
As you can see in this image:. I am using Unity 5. More recent versions of Unity 5. Doing the steps from this post on the ARToolkit github might resolve the issue but I did not try it so I cannot assure you it will work.
When starting Unity you will have to create a new unity project. You can delete the two objects that every new project starts with: To use the ARToolkit package downloaded from the webpage you will have to import the package to your project: Next go the folder where you downloaded the ARToolkit to and double click on it.
In the next window click on import to import the whole package.
If everything is imported correctly there should be no errors in the console window. Once everything is imported the next step is to populate the empty scene. We will need three empty objects and one camera object. If done correctly the Hierarchy window in Unity should look like this:. After populating the scene in Unity we will start using the imported ARToolkit package.
In the inspector window we will have to make some adjustments to the added scripts to get them working. In this component we will not have to change anything. The last adjustments we will have to make are to the layers of the objects.

At this point everything is ready to make an AR app be it for the pc or mobile phone. Building the app at this point will look like it is not working. This is the object that will appear on the screen. As making beautiful intricate objects in Unity is not a part of this tutorial we will add a simple cube or sphere.
Change the scale in X, Y and Z to 0. You can always change the size to whatever you prefer later. Now zoom in to the object.

To make sure the object is projected above the marker move the marker in the negative Z direction to about It is always possible to change this to the amount you want, but after some tests I found We are finished and ready to test it!
If we push the play button the object will appear on top of the marker when we put the pattern in front of the camera. The last thing we need to do is make a nice mobile app. To make an Android app of the project we just created you could just try to build it and choose Android as the Platform. When doing this myself I did not get the camera stream as soon as I started the app.
After some tweaking I found that the settings in the Plugins of the ARToolkit package needed changes from its initial settings.

It may work for you with these initial settings, but I had to change them. To change the settings you will have to choose the Plugins folder in the Assets. You will see 6 folders Android, ARWrapper. The Metro folder has two subfolders, Win81 and WindowsPhone Which have multiple subfolders themselves. In subfolder arm of Win81 click on the ARWrapper file and make sure nothing is selected.
The WindowsPhone81 folder has two subfolders, arm and x Make sure that nothing is selected in the ARWrapper file in both folders. It maybe that on windows machines other operating systems appear, I would make sure that x86 is checked for every appearing operating system. Now make sure only the checkbox for your created scene is selected. Under Platform select Android and click on the Player Settings button. It will open some settings you can change in the inspector window.
The only thing I changed here was the name of the app in the Product Name textbox. This is the name that will appear on your mobile phone, so choose a nice one. You can add a default icon or change the company name to make the app more personal.
Then click the build button and save it wherever you prefer. After the apk file is created copy it to your phone and install it. After installation the first time you run the app, it will ask for permission to use the camera. Of course this is needed for augmented reality so allow it.
The only thing left is to make a birthday card. You can make any card you imagine as long it has the marker somewhere hidden.
Do not make the marker too small, otherwise it will not recognize it. Also make sure the black outer border of the marker is qrtoolkit. Also visible in the video is that it is not very stable if the marker is small. The closer you put the camera to the marker, the more stable the object appears. Do you have any questions about this article? Do you have any suggestions for a new AR tutorial? Let me know in the comments section below.
Did you do the last part? I had a problem like thatbut making the changes as the instruction says solved it for me. Thank you so much! Finally I could create an app with it.
