1. Visualising the use of biometric systems: tackling symbolism, context, and interpretation Patrick Hofmann patrick@designpH.com | Sydney

2. In the next 20 minutes 1 Placement and context 2 Biometrics visualisations

3. Placement and context 1

4. What is this?

16. Pointing upward? Signalling importance? Directing movement? Denoting fingerprinting?

17. What is this? On a flag? On a calculator? In a screen interface? On a building? On a medicine bottle? On a biometric device?

18. What is this? On a shopping mall map? On a food package or recipe? On a mobile phone? On a biometric device?

19. What is this? On a machine dial or knob? On a milk carton or bottle? On a browser? On a biometric device?

20. What is this? In a hardware store? In the margin of a user guide? In a cartoon above someones head? On a biometric device?

21. Biometrics visualisations 2

22. Full instructions Intended to be read before using the biometric device Or placed in the biometric device Better integrated as individual symbols into the dynamic feedback of the biometric device display

23. Levels of visualisation Realistic and representative Symbolic and abstract

24. Usability challenges Mobility Flexibility Accessibility Fatigue Crossover experiences

25. Usability findings Context is important Order is important Parallelism is important You cant simply mix and match You cant simply ask What does this mean? More findings tomorrow with Mary Theofanos
