How to Set Up a VR Project

How to Set Up a VR Project

Introduction

In the following article we will outline the basics to start designing a virtual reality (VR) project. The immersive projects and questions are available depending on your license type, please reach out to our support team or your sales agent for more information on this. 

Enabling VR in Project Settings

The first step is to enable your project as a VR project. After creating a project, go to Settings > Project Settings > Enable XR.
After enabling XR, you can select VR in the XR Configuration.


Enabling VR Screen Settings

With the XR setting enabled, you will be able to modify the screen properties in order to include VR settings. Click on edit screen properties, and you will be able to enable VR on the screen level.


Modifying VR Screen Settings

From the edit screen there are important settings that can be modified.
The User Input Device will indicate whether participants answer through their gaze (focus x amount of time to the answer option to select it) or with the go controller. 
You can use the Background source to pick background images images from the EyeQuestion library. If you select Custom, you will be able to select from your own 360° images or 360° videos. If you want to use a 360° video, please make sure that the video has a frame width of 2048px and frame height of 1024px.
The Rotation will rotate the image starting point. 
There is also the possibility to select from a library of available sounds, these sounds can be play in a loop if this setting is enabled. 


If VR product is set, this image will be displayed on all the questions of the screen. 
Using the Scale option you can increase or decrease the image size. You can change to position of the image using the Position settings and decide if you want the image to Rotate. Rotation would be mainly applicable for 3D models.

Adding VR Questions

There are already 6 pre-defined immersive questions that are compatible with VR projects. Questions outside the folder 10.Immersive Questions VR (ADV) are non compatible with immersive VR projects and should not be used.
After the screen has been set, go to Add questions > 10. Immersive questions VR (ADV). From here you can pick the questions that are suitable to use with VR.


Adding VR Questions: Category/Hedonic (One-Choice)

In the example below a category question has been added. In this case we also have added a picture to each item to increase the immersive experience. If you click on the play icon you can add an image or a 3D model. Using the Scale option you can increase or decrease the image size.
If you do not add an image, it is possible to use the Description field to show the answer options. You can also use the description in combination with an image.
The Description position option allows you to move the description on the y-axis, so higher or lower on the screen.



In addition, each immersive question has its own VR settings.

The Question Wait setting is the amount of seconds before the question is displayed. You can for example use this to let someone get familiar with the immersive environment for an x amount of time. After this time, the question will appear.
Question Angle determines the location of the question on the screen. The default is 0: the question is displayed in front of you.
When Auto Submit is enabled the question will auto submit the answer the moment an answer is selected.
If you selected Item positions fixed then the answer items will be displayed horizontally and the space in between the items is determined by the Angle (see below). If you disable this option, you can set the position for each individual answer item by going back to the item options.


The Angle determines the angle in between the items (in degrees). This is the space between the answer options.
Gaze Duration is the time a participant has to focus on an item before it is selected. This is applicable in case the screen setting User input device is set to Gaze.
When the Use Instruction Setting is enabled, then instructions can be added to a participant via the Instruction Text setting. This can for example be the question text.


General Tips

  1. It is not possible to use special characters such as Ø ï ë é in question instructions or answer options. Please avoid these type of characters. It is fine to use characters such as ! @ # $ % ^ & *. In case a special characters is used that is not allowed, the specific character will not be visible to the panelist while filling in the project.
  1. In a regular (non immersive) EyeQuestion project, all the questions that are included on one screen are shown at the same time. In a VR project, the questions that are included on one screen are displayed one by one after each other.
  1. To add a general instruction to your participants in VR, you can create a category question without any answer options and use the instruction text option. Please make sure to set the question to non mandatory.
  1. For the moment, the following options are not compatible with immersive VR projects: branching (show on switch, screen/question conditions) and placeholders. When you create a project with a design, you can only use runtime options “Automatically” and “ No validation”. Alternatively you can create a project without a design and create one screen per product evaluation. You can randomize the screens by using the Random Group option on the screen setting. All screens that have the same Random Group assigned will be randomized with each other.
