Superman vs Giant: A Study on Spatial Perception for a Multi-Scale Mixed Reality Flying Telepresence Interface

Area of Science:

• Human-Computer Interaction
• Virtual Reality
• Mixed Reality

Background:

• Advancements in Mixed Reality (MR), Unmanned Aerial Vehicles (UAVs), and collaborative virtual environments offer new remote collaboration interfaces.
• Large-scale remote collaboration, such as in construction, requires innovative telepresence solutions.

Purpose of the Study:

• To explore a novel flying telepresence concept for multi-scale mixed reality remote collaboration.
• To investigate the influence of interpupillary distance (IPD) and eye height manipulation on user perception within virtual environments.

Main Methods:

• Conducted a user study with three experiments.
• Experiment 1: Compared static and dynamic IPD interfaces for simulator sickness and body size perception.
• Experiments 2 & 3: Tested user perception of virtual object size and body size using manipulated IPD and eye height in varied visual cue environments and stereo video footage.

Main Results:

• Manipulating IPD and eye height significantly influenced user size perception.
• Findings provide insights into user experience with dynamic IPD and varying visual cues.
• Stereo video footage effectively simulated a flying telepresence experience for user studies.

Conclusions:

• Flying telepresence is a viable concept for multi-scale MR remote collaboration.
• Recommendations are provided for designing effective multi-scale MR flying telepresence interfaces.
• Further research can optimize these interfaces for applications like construction.
