Tutorial: Inclusive treasure hunting with and without vision! ***Summary***

What do I need ?

• a PC
• a compatible smartphone (list available in the table at this link https://developers.google.com/ar/discover/supported-devices) and usb cable to send a file to the smartphone (otherwise bluetooth works but is longer)
• a set of softwares to install, as explained step by step in the tutorial: Unity, Android Build Support, ARCore package for Unity, JDK, SDK Android (Android studio)
• a audio file, MP3 for example, which will be the sound of your treasure (it can be a sound of sonar, a beep or a music).
• Warning ! At your first use, you need the internet to create and connect to a Unity account to enable features

Steps

• Install Unity ( https://unity3d.com/fr/get-unity/download )

Warning ! At your first use, you need the internet to connect to a Unity account (and create one if you do not have one by clicking on "create one") as requested (illustration). The next uses do not require a connection, except if you want to download a Unity element (for example, a 3D element to decorate your virtual scene download in the Assets Store).

• Create a project

• Download, install and import ARCore package
• Open the scene "HelloAR"
• Create a prefab with an audio source configured to be a 3D audio feedback, and "Loop" if you want it plas continuously

This object is potentially a treasure chest downloaded on the Asset Store.

• Replace "Andy" in Example Controller by prefab with sound
• Install the JDK
• Install Android Studio or Android SDK tools (Command line tools only) for Android N (API 24) and over
• Enter the location of Android in Unity
• Config the build settings and the player settings to generate the application
• "Build" the apk
• Install ARCore on the smartphone
• Download the apk on the smartphone, and open it to install the app
• Use the app
