- 6. // QUESTIONNAIRE Each interviewee, before the interview, was invited to fill in a questionnaire that allowed us to gather very useful information about their personal profile useful for identifying possible influences in the answers. The questionnaire showed 66% of interviewee are usual to drive the car mostly alone, without passengers. Moreover we verified that even older interviewees have a fair confidence with technological devices. INTERVIEWS // 6

- 31. // METHODOLOGY HEURISTICS ANALYSIS // In order to improve the system usability, we conducted an heuristic analysis, checking the system performances related to these topics: 1. Visibility of system status 2. Matching system and real world 3. Standards and consistency 4. Error prevention 31
- 32. // VISIBILITY OF THE SYSTEM STATUS HEURISTICS ANALYSIS // 1. Visual hints to show the active status 2. Speedometer is clearly visible 32
- 33. // VISIBILITY OF THE SYSTEM STATUS HEURISTICS ANALYSIS // 3. Top bar 4. Navigation status 33
- 34. // MATCHING SYSTEM AND REAL WORLD HEURISTICS ANALYSIS // 1. Real world references in icons 2. 3D navigation system 34
- 35. // STANDARDS AND CONSISTENCY HEURISTICS ANALYSIS // 1. Icon design is coherent between screens 2. Coherent color palette between screens 3. Coherent fonts 35
- 36. // ERROR PREVENTION HEURISTICS ANALYSIS // 1. Commands safe position 2. Physical buttons for better precision 36
