How three-dimensional sketching environments affect spatial thinking: A functional magnetic resonance imaging study...

Area of Science:

• Cognitive Neuroscience
• Human-Computer Interaction
• Design Studies

Background:

• Sketching is crucial for design ideation.
• Virtual reality (VR) enables immersive 3D sketching.
• Limited research exists on cognitive differences between 3D and 2D sketching.

Purpose of the Study:

• To investigate differences in spatial and visual cognitive functions between 3D and 2D sketching.
• To analyze functional magnetic resonance imaging (fMRI) data to compare brain activation patterns.
• To understand the impact of immersive sketching environments on design processes.

Main Methods:

• Recruited 20 students with landscape drawing experience.
• Utilized Oculus Quest VR for 3D sketching and iPad Pro for 2D sketching.
• Analyzed fMRI data during various sketching tasks (lines, objects, scenes).

Main Results:

• Significant differences in brain activation (e.g., middle temporal gyrus, parietal lobe) between 3D and 2D sketching.
• Distinct brain area activation for visual recognition, composition, and spatial perception across sketching conditions.
• 3D sketching, particularly in VR, appears to engage more visual-spatial functions.

Conclusions:

• Immersive 3D sketching environments may enhance visual-spatial processing compared to 2D methods.
• Findings suggest VR sketching's potential for design education and spatial thinking development.
• Further research can explore the implications for various design disciplines.
