• Are YAH maps in alignment with people’s perception of the environment?

• Should indoor and outdoor YAH maps differ?

• Are YAH maps easily interpreted?

Research Design
Area of study
Materials and Procedure
Gender and reference frames
Importance of landmarks
Cognitive mapping is complex
1888 building & outdoor surroundings in Parkville Campus
13 students from GEOM90016 class
Santa Barbara Sense of Direction Survey
Indoor Survey
Outdoor Survey

Research Outline
Research Motivation
Previous Research
Research Design
Wayfinding requires spatial knowledge communication
Symbol simplicity and consistency
A person's orientation skills are important
From the surveys we found:

No correlation between the SBSOD survey and the results of the survey tasks.
No correlation between the building familiarity and the spatial surveys
Participants showed more disorientation in the outdoor environment than indoors
YAH maps are not always in alignment with people’s perceptions of the environment.
YAH maps for emergency evacuation show significant cognitive challenges in interpretation, failing to update one’s cognitive map
Indoor Map
Unexpected results:
SBSOD survey results not related to results on:
direction/orientation survey
map reading survey
environmental knowledge
Primary factors that may have influenced participant’s spatial ability during the experiment:
Participants rely on maps rather than their own spatial perception
Map design
Map orientation
The sample used was not a fully random subset of the population

Small sample size, with only 13 subjects
Outdoor Map
Expected results:
SBSOD results were found to be slightly towards the higher end of a range of results obtained by Montello and Xiao (2011)
Inconsistency in the survey responses:
YAH maps not easily interpretable
