PointAR

PointAR is a concept app showcasing the use of Augmented Reality to assist the foreign workforce with the induction process through the use of 3D animation for visualisation and built-in translations. Check out the app on the Google Play Store.

Markers

The app was developed with the following 2 signs in mind:

"Lift with your legs" sign"Open holes" sign

Scripts

The app has the following three custom scripts, coded in C#, within the “/assets/_Scripts” folder:

Name Description
AutoFocus.cs Used to configure Vuforia to use autofocus on the device’s camera.
playbackspeed.cs Controls the playback speed of the animation.
translate.cs Used to translate each sign by selecting a language from a drop-down menu.

Each script includes in-line comments explaining what the line is used for.

How to use

  1. Begin by downloading the project and opening it into Unity. Note the project was last used in Unity 2018.1.6f1.
  2. Navigate to the _Scenes folder, and load the main scene by double-clicking it.
  3. Select the AR Camera component from the hierarchy, and under the Vuforia Behaviour component, click on Open Vuforia Configuration.
  4. Press the Add license button just below the App License Key field. This step is required for Vuforia to be enabled. You will be redirected to the Vuforia Dev Portal. Login or register with a free account, and generate a new license key.
  5. Copy the license key and paste it into the App License Key input field encountered in step 3.

How it works

The main menu consists of a drop-down menu and a start button. The scene is composed of two Vuforia ImageTarget GameObjects, one for each sign, with images of the translated sign as children GameObjects. The drop-down menu has the script translate.cs attached as a component, and takes each translated sign as an input.

Overview of translate.cs component

The script then creates an event, onValueChange, which detects when the user changes the language. Each sign is hidden by default. When the onValueChange event is triggered, it will display the correlated sign (i.e. “Italian” will un-hide the Italian translation, while keeping “Lithuanian” and “Urdu” translations hidden).
