Creating a VR Questionnaire Tool

This project is already assigned.


VR applications are commonly used in the healthcare context. For example in an exposure therapy to learn how to cope with a specific anxiety or in a gait rehabilitation application that can be applied after someone suffered from a stroke. Applications like these often include a supervisor who is monitoring and adapting the VR-therapy session. In order to do this, the supervisor must be able to constantly assess the current state of the client. One way to obtain an assessment of the user’s condition would be through subjective feedback by the client, i.e. questionnaires. Thus, in this project we would like to build a tool for Unity that enables a supervisor to create his/her own questionnaires and display them in VR.

For more detailed information about the motivation of this project, have a look at [1].


This is how the project could be structured. This is of course adjustable during runtime.

  1. Survey existing tools and common use cases, e.g. [2][3]
  2. Define the aims of the project more precisely
  3. Get familiar with Unity
  4. Build a tool that lets a user create questionnaires, consisting of different question types
  5. Implement a save and load mechanism for the questionnaires
  6. Prepare the questionnaires to be shown and answered in VR
  7. Implement a save mechanism for the answers to the questionnaires
  8. Integrate the prototype into existing structures of the VIA-VR project
