Description: Researchers capture and compare designs, systems, and artifacts through standardized questionnaires in virtual reality (VR). However, there exists a wide range of interaction techniques that can be used to fill in questionnaires. This includes, for example, mid-air pointing gestures, gaze-based interactions, touchpad, speech input, or controller-based ray-casting. While previous research investigated how different 3UIs, in-VR vs. outside-VR, or tools affect participants' responses, this thesis focuses on different interaction techniques when using the same questionnaire UI. The results of this thesis ought to inform the design of VR questionnaires, especially since VR is frequently used as an alternative research platform.  

Goal of Thesis

The goal of this Bachelor/Master thesis (level will determine the scope) is to identify a set of the most widely used VR interaction techniques, integrate them into the open-source VR questionnaire toolkit¹, and conduct a user evaluation to investigate potential differences.

1. Review of the related literature to identify commonly used VR interaction techniques and widely used questionnaires.
2. Implement the VR interaction techniques in the existing open-source VRQuestionnaireToolkit²
3. Conduct a quantitative evaluation to assess how the choice of the interaction technique affects responses in VR questionnaires.

Requirements
