An important aspect of humane interfaces is meeting the needs of a variety of people. They all have different skills, restrictions and whims. How do you figure out what exactly those are?

In this presentation I’ll talk about how I used user interviews and personas for that purpose, using them as tools for discussions and implementation of Public Transportation in GNOME Maps. I'll talk about how I interviewed people from both cities and countryside, from both Brazil and Sweden, and how their insights challanged my own perceptions about what people need from a public transportation UI.
