Wayfinding and acquisition of spatial knowledge with navigation assistance

Area of Science:

• Human-Computer Interaction
• Cognitive Psychology
• Virtual Reality

Background:

• Assisted navigation systems often use integrated visualizations.
• Understanding how these visualizations impact spatial learning and wayfinding is crucial.

Purpose of the Study:

• To investigate how integrated visualizations support wayfinding and spatial learning.
• To determine the effectiveness of different visualization types and alignment on spatial knowledge acquisition.

Main Methods:

• Participants navigated a virtual environment with assisted visualizations.
• Wayfinding accuracy was measured.
• Self-to-object and object-to-object spatial knowledge were assessed using pointing and configurational tasks.

Main Results:

• Self-to-object knowledge was enhanced by self-to-targets visualizations providing egocentric directional cues.
• Comprehensive map visualizations supported both self-to-object and object-to-object knowledge acquisition.
• Visualization alignment improved self-to-object knowledge with self-to-targets visualizations but not with maps.
• Misaligned visualizations hindered wayfinding, especially for individuals with lower perspective-taking abilities.

Conclusions:

• Visualizations are encoded egocentrically for wayfinding in assisted navigation.
• Appropriate visualizations can effectively support the acquisition of egocentric self-to-object spatial knowledge.
• Visualization alignment is critical for effective wayfinding, particularly when using egocentric directional cues.
