After understanding the users’ problems, I developed an initial user flow, shown below. However, the user research with disabled people showed me the problems of my early sketch, so I turned my focus on the features that help disabled people to fully utilize the existing subway’s assistive devices. Here are the problems with the initial sketch:
- Disabled people could not find the existing accessibility devices of the subway shown in the app, which discouraged them to use the app.
- The real-time update of the corresponding subway route’s status is subtle and invisible to the users, which caused them to think there was a connection problem.
- Disabled people could not find the differences in the features between my app and the other navigation app such as google map.
