The Effect of Scale Consistency between Real and Virtual Spaces on Immersion in Exhibition Hybrid Spaces
Qiong Wu, Yan Dong, Zipeng Zhang, Ruochen Hu

TL;DR
This study investigates how scale consistency between real and virtual spaces affects user immersion in exhibition hybrid environments, identifying optimal virtual space and avatar sizes to enhance immersive experience.
Contribution
It provides systematic insights into virtual-to-real scale ratios and avatar sizing that maximize immersion, based on experimental data and real-world application.
Findings
Participants preferred a virtual space scale of around 130%.
Optimal avatar sizes for immersion are within 75%-100%.
Deviations from real height reduce immersion significantly.
Abstract
In exhibition hybrid spaces, scale consistency between real and virtual spaces is crucial for user immersion. However, there is currently a lack of systematic research to determine appropriate virtual-to-real mapping ratios. This study developed an immersive interaction system based on Intel 3D Athlete Tracking body mapping technology. Two experiments investigated the impact of virtual space and virtual avatar scale on immersion. Experiment 1 investigated 30 participants' preferences for virtual space scale, while Experiment 2 tested the effect of 6 different virtual avatar sizes (25%-150%) on immersion. A 5-point Likert scale was used to assess immersion, followed by analysis of variance and Tukey HSD post-hoc tests. Experiment 1 showed that participants preferred a virtual space ratio of 130% (mean 127.29%, SD 8.55%). Experiment 2 found that virtual avatar sizes within the 75%-100%…
