How it works
The idea for the app was first floated by 50-year-old Danish furniture maker Hans Jørgen Wiberg almost two years ago. Visually impaired users can take a picture of an object with a smartphone camera and send a request to a community of helpers via the app. A volunteer then accepts the request for help and responds to the user by describing the object via live video.
Easy to use
The app is designed to be as user-friendly as possible. It features an easy user interface, which requires one to sign up via an email address or a Facebook account. The visually impaired user then accesses the app on their phone to request assistance. A user can choose to block another user if he or she is unhelpful, thus preventing unwanted intrusion. The ease with which people can access this app can potentially lead to its malign use, as sighted users can deliberately give out false information to the blind. However, such incidents have not been reported yet.
Among the many interesting features of this app, users can communicate in 80 languages and choose more than one language through the settings on their phone to help an international set of users. Moreover, this app is free of cost until September when the developers will run out of initial funding. After that, they will create a sustainable business model, which includes subscriptions and donations.
