A Literature Review and Taxonomy of In-VR Questionnaire User Interfaces

TL;DR

This paper reviews existing VR questionnaire user interfaces, highlighting their advantages and disadvantages, and introduces a taxonomy to categorize these solutions, addressing a gap in comprehensive understanding of in-VR questionnaire methods.

Contribution

It provides the first systematic literature review and taxonomy of in-VR questionnaire UIs, offering a structured overview of current solutions and their characteristics.

Findings

Embedded VR questionnaires reduce bias in immersive experience evaluation.

The taxonomy categorizes VR questionnaire UIs based on design and implementation features.

Review identifies gaps and future directions for VR questionnaire research.

Abstract

Previous research demonstrates that the interruption of immersive experiences may lead to a bias in the results of questionnaires. Thus, the traditional way of presenting questionnaires, paper-based or web-based, may not be compatible with evaluating VR experiences. Recent research has shown the positive impact of embedding questionnaires contextually into the virtual environment. However, a comprehensive overview of the available VR questionnaire solutions is currently missing. Furthermore, no clear taxonomy exists for these different solutions in the literature. To address this, we present a literature review of VR questionnaire user interfaces (UI) following PRISMA guidelines. Our search returned 1.109 initial results, which were screened for eligibility, resulting in a corpus of 25 papers. This paper contributes to HCI and games research with a literature review of embedded questionnaires in VR, discussing the advantages and disadvantages and introducing a taxonomy of in-VR questionnaire UIs.
