    • Typical Plan Layout of Signs For ‘Cable Cars’
    • ‘Cable Cars’ - Lessons Learnt• Paper based ergonomic evaluation difficult to do.• Attempting a 3D assessment in a 2D representation• Need for simple quick and low cost modelling.
    • Development of Wayfinding Tools:Objectives & Concepts
    • Study Objectives• Improve measurement of wayfinding performance• Robust and reliable• Easy to use• Applicable to new works and modifications• Difficulty of ‘putting oneself in visitors shoes’• Develop metrics
    • Survey Results On Wayfinding Negative Features Frustration Confusion due to information overload Confusion due to retail and directional infor Lack of awareness of time and distance information Poor terminology Lack of recovery clues Inadequate lighting/auditory environments
    • Example Of Wayfinding Metrics
    • Example Of Wayfinding Metrics
    • Analysis Of Photographic ImageClass of sign Number in visual Area in photo % of total field (mm squared)Primary 2 470 2%Secondary 2 1270 6%Other 4 630 3%
    • Measure Of Visibility At Decision Points
    • Scoring Visibility & Relevance of Signs
    • Scoring Visibility & Relevance of SignsConnection: Entrance to - Visibility Weighting Score 1 toilets 1 0.8 0.8 2 shops 1 0.5 0.5 3 check-in 0 1 0 4 security 1 1 1 5 café 1 0.3 0.3 AVERAGE 0.52
