Exploring Horizontally Flipped Interaction in Virtual Reality for Improving Spatial Ability

Area of Science:

• Human-Computer Interaction
• Cognitive Science
• Neuroscience

Background:

• Spatial ability is crucial for academic and professional success.
• Virtual reality (VR) offers immersive environments for skill development.
• Practicing spatial tasks, like mental rotation, enhances spatial skills.

Purpose of the Study:

• To investigate the effects of a novel "mirror-reversed" VR interaction on spatial ability, brain activity, performance, and user experience.
• To compare the mirror-reversed interaction against standard controls in a cup stacking task.
• To explore VR's potential for spatial skills training.

Main Methods:

• A between-subjects user study comparing mirror-reversed VR controls with standard controls in a cup stacking task.
• Assessment of spatial ability using mental rotation and perspective-taking tests.
• Measurement of brain activity using electroencephalography (EEG) focusing on theta and alpha bands.
• Tracking task performance and user experience.

Main Results:

• No significant group differences in overall spatial test scores, but a trend towards improved spatial orientation in the mirror-reversed group.
• Both groups showed a trend towards improved mental rotation; task completion times decreased over time for all participants.
• EEG data indicated a significant increase in theta band power in the mirror-reversed group, with no significant difference in alpha band power.

Conclusions:

• The mirror-reversed VR interaction shows promise for enhancing spatial orientation and potentially altering brain activity related to spatial processing.
• VR environments can be utilized for targeted spatial skills training, with novel interaction techniques warranting further investigation.
• Findings encourage the development of more complex and spatially demanding VR interactions for cognitive training.
