Redesigning navigational aids using virtual global landmarks to improve spatial knowledge retrieval

Area of Science:

• Human-Computer Interaction
• Cognitive Science
• Spatial Navigation

Background:

• Current navigation aids predominantly use beacon-based, turn-by-turn instructions.
• Over-reliance on these aids leads to a decline in users' spatial skills and environmental awareness.
• Map-based learning is crucial for developing cognitive maps and fostering independent navigation.

Purpose of the Study:

• To propose and evaluate a novel navigation assistant supporting map-based learning.
• To investigate the efficacy of the virtual global landmark (VGL) system in enhancing spatial navigation.
• To reverse the decline in spatial skills caused by current navigation technologies.

Main Methods:

• Development of the virtual global landmark (VGL) system, an augmented reality (AR) tool.
• Implementation of a map-based strategy using a continuously visible landmark.
• Experimental comparison of VGL system's effectiveness against traditional methods with 27 university students.

Main Results:

• Participants using the map-based strategy with the VGL system processed more spatial information.
• The VGL system encouraged greater engagement with the surrounding environment.
• Navigation efficiency and accuracy were significantly improved when using the VGL system.

Conclusions:

• The virtual global landmark (VGL) system effectively supports map-based learning for active navigation.
• Augmented reality navigation aids can be designed to enhance, rather than degrade, spatial skills.
• This approach offers a promising method to counteract the negative effects of current navigation technologies on cognitive abilities.
