‘In this project, we developed an Android app called GuideMe. It connects two groups of users: the visually impaired people (users) and the volunteer helpers (helpers). The users need help in a variety of situations, such as when they walk on an unfamiliar street or when they look for something in the room, in which case a helper could provide guidance. A user can use the app to find/choose a helper among several available ones, then starts a video talk with him/her. As the talk going on, the helper can observe the visual surroundings of the user, and give suggestions/serve as user’s eyes. If requested, a map component will show on the app, assisting helper to be more effective guiding users. During the development of this project, we performed the requirement analysis by meeting with potential users and collecting their input. We designed and revised UI and features based on the iterative feedback. We performed research on current popular technologies on server and mobile development, to build our technology stack and architecture. And then we created all the code, including an Android client, a Node.js server and a MongoDB database. We also performed tests to evaluate for the performance of the app, and compared it with the apps in the same area.
