Data for "Direct and indirect Rod and Frame effect: A virtual reality study"
Description
This dataset contains the raw experimental data and supplementary materials for the "Asymmetry Effects in Virtual Reality Rod and Frame Test". The materials included are: • Raw Experimental Data: older.csv and young.csv • Mathematica Notebooks: a collection of Mathematica notebooks used for data analysis and visualization. These notebooks provide scripts for processing the experimental data, performing statistical analyses, and generating the figures used in the project. • Unity Package: a Unity package featuring a sample scene related to the project. The scene was built using Unity’s Universal Rendering Pipeline (URP). To utilize this package, ensure that URP is enabled in your Unity project. Instructions for enabling URP can be found in the Unity URP Documentation. Requirements: • For Data Files: software capable of opening CSV files (e.g., Microsoft Excel, Google Sheets, or any programming language that can read CSV formats). • For Mathematica Notebooks: Wolfram Mathematica software to run and modify the notebooks. • For Unity Package: Unity Editor version compatible with URP (2019.3 or later recommended). URP must be installed and enabled in your Unity project. Usage Notes: • The dataset facilitates comparative studies between different age groups based on the collected variables. • Users can modify the Mathematica notebooks to perform additional analyses. • The Unity scene serves as a reference to the project setup and can be expanded or integrated into larger projects. Citation: Please cite this dataset when using it in your research or publications.

Steps to reproduce
1. Setup the VR Environment • Implement the virtual reality test room using the Unity 3D engine. • Display the scene through an Oculus Rift headset with a field of view of 80° (horizontal) and 90° (vertical) per eye at 1080×1200 resolution. • Enable built-in anti-aliasing for smoother edges. 2. Define the Scene Parameters • Use Unity’s unit system, where 1 unit ≈ 1 meter. • Place the subject 5 m away from a 1.3 m rod inside a cuboid room (1.8 m × 1.8 m). • Illuminate the scene with a spotlight positioned behind the subject. 3. Configure the Experiment • Present 19 frame tilt angles (-45 degrees to 45 degrees in 5 degrees increments). • Define counterclockwise rotations as negative and clockwise as positive. • Start each rod at 5 degree closer to vertical than the frame tilt angle. 4. Subject Preparation • Seat the subject in a chair with a backrest. • Fit the Oculus Rift headset comfortably. • Provide a familiarization phase (~5 min) with an instructional VRRFT software variant. 5. Conduct the Test • Display the tilted frame continuously during the test. • Allow the subject to adjust the rod’s angle using a wireless mouse wheel (sensitivity: 0.5 degree). • Have the subject verbally confirm completion of each trial. • After each trial, smoothly return the frame to vertical for 2 seconds before presenting the next tilt angle. 6. Data Collection • Record the final rod angles for each trial.
