Short answer

Incorporate the VEQ into your VR design process to measure and improve user embodiment, focusing on aspects of ownership, agency, and body schema perception.

Field: User-Centred Design
Source: IEEE Transactions on Visualization and Computer Graphics (2020)
Method: Psychometric scale development and validation
Sample: 218 participants (196 in initial CFA, 22 in reliability/validity study)
Evidence: Strong effect

A validated questionnaire can reliably measure user embodiment in virtual reality, encompassing ownership, agency, and body schema perception. This user-centred design research insight is drawn from a 2020 study published in IEEE Transactions on Visualization and Computer Graphics. Using Psychometric scale development and validation with 218 participants (196 in initial CFA, 22 in reliability/validity study), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Incorporate the VEQ into your VR design process to measure and improve user embodiment, focusing on aspects of ownership, agency, and body schema perception.

Virtual Embodiment Questionnaire (VEQ) quantifies user immersion in virtual environments

A validated questionnaire can reliably measure user embodiment in virtual reality, encompassing ownership, agency, and body schema perception.

IEEE Transactions on Visualization and Computer Graphics · 2020

Key Findings

01The Virtual Embodiment Questionnaire (VEQ) reliably measures three key factors of embodiment: ownership, agency, and perceived change in body schema.
02The VEQ demonstrates reliability and validity, even when subjected to variations in simulation latency.

Application

Design takeaway

Incorporate the VEQ into your VR design process to measure and improve user embodiment, focusing on aspects of ownership, agency, and body schema perception.

How to apply

Administer the VEQ to users after they interact with a VR system to gather data on their embodiment experience, and use this data to refine design elements.

Project actions

01When designing VR experiences, consider how to enhance the user's sense of ownership and agency over their virtual avatar.
02Think about how the virtual environment and avatar design can influence the user's perception of their own body schema.

Method & Evidence

AimTo develop and validate a reliable instrument for measuring the perceptual aspects of user embodiment in virtual reality.

MethodPsychometric scale development and validation

ProcedureLiterature review to identify constructs, item generation, confirmatory factor analysis (CFA) across multiple experiments, and reliability/validity testing by examining the impact of simulation parameters like latency.

Sample218 participants (196 in initial CFA, 22 in reliability/validity study)

ContextVirtual Reality (VR) applications

Variables

IVLatency and latency jitter in the VR simulation

DVScores on the Virtual Embodiment Questionnaire (VEQ) subscales (ownership, agency, body schema change)

CVVirtual environment, avatar appearance, task performed in VR, participant demographics

Strengths & Limitations

Strengths

+Data-driven development and validation of the questionnaire.
+Inclusion of multiple experimental studies to confirm psychometric properties.

Limitations

The sample size in the validation study was small, and the types of VR interactions tested were specific. Generalizability to all VR applications might be limited.

Reliability & validity

The study used Confirmatory Factor Analysis (CFA) to establish construct validity and conducted further tests to confirm the scale's reliability and validity, including its robustness against simulation latency.

Think critically

How might the cultural background or prior VR experience of a user influence their responses on the VEQ, and how could this be addressed in future research or application?

Design Principles

"Quantify user embodiment in virtual environments using validated psychometric tools to inform design decisions."

Understanding how users perceive and connect with virtual bodies is crucial for designing more engaging and effective VR experiences. This validated instrument allows for objective assessment of these perceptual aspects, informing design iterations and performance evaluations.

What This Means for Your Design

This research created a survey to measure how much people feel like they are 'in' a virtual world and have a virtual body. It found that people feel more embodied when they feel ownership and control, and when their sense of their own body changes. The survey works well even if the virtual world has small delays.

How to use in your project

1.Use the VEQ as a tool to gather quantitative data on user experience in your VR design project.
2.Analyze the VEQ results to identify areas where user embodiment can be improved through design changes.
