In this tutorial, you will learn how to use the Head-Up Display (HUD) feature.
The HUD is a display that allows the user to see displayed data or elements directly in the line of sight, without looking away from the usual viewpoint. These data or elements are attached to the camera and follow the user as he or she moves.
Let’s see two of the most used examples of the HUD group:
- A text or a video that accompanies the user throughout a training course.
- Clues that appear to guide the user through a game or search.
Feel free to use this feature for other goals and scenarios.
For this tutorial, we will perform the scenario below:
"In this experiment, a video starts at the beginning of the scene. Once the video ends, a quiz appears. This quiz is connected to the HUD and will follow the user’s movements. After answering the question, a ‘Congratulations’ message appears."
Here are the steps for this example:
- Insert a video
- Create a quiz and drag it into the HUD group
Step 1: Insert a video
In the left panel, select “Add an element” (+ button) then choose “Video”.
After defining your media, place your video where you want it to be. This article explains how to do so: First experience step by step
Step 2: Create a quiz in HUD
In the left panel, select “Add an element” (+ button) then choose “Quiz”.
After creating your quiz, select the quiz and drag it to the HUD group in the right column.
Here is the process :
Step 3 : test the HUD
Here is the final result
Please note that depending on your deployment context, you will need to adapt the position of the elements in your HUD group. You can read our article on the subject:
