Summary
We went through three rounds of iteration, we gathered valuable feedback from a diverse group of 10 individuals, including passengers with reduced mobility, tourists, and experts.
Prototype
Our approach included developing different levels of app prototypes, storyboards, and service blueprints based on the specific needs of the users we were validating with.For some user groups, we utilized app prototypes to provide a hands-on experience, allowing them to interact with the service and provide valuable feedback on its functionalities and user interface. Storyboards were employed to visually illustrate the user journey and showcase how the solution would address their preferences and pain points.For other user groups, service blueprints proved to be more suitable for mapping out the end-to-end user experience and service interactions.

Storyboard Prototype
Iterations
1st
The need for practical guidance outside of public transport became apparent in the initial prototype. To address this, we implemented a comprehensive guide to assist users throughout their journey beyond public transportation. Additionally, the introduction of a widget provided a quick and convenient way for users to adjust settings without opening the app.
2nd
Based on user feedback, we learned that haptic feedback is essential to our audience to eliminate the need for users to expose their phones during their commute. This enhancement significantly improved the user experience by offering intuitive navigation cues without requiring visual interaction. Furthermore, we acknowledged that users preferred in-app permissions.
3rd
Trust emerged as a critical aspect of our solution. Users expressed initial skepticism about advanced functionalities being implemented in public systems.
