Accessible messaging app for blind people: users, core flows and metrics

Design a messaging app in the spirit of WhatsApp for people who are blind. Decide exactly who you are designing for, what the app must let them do, and how you would know it works for them. ```hint Close your eyes Walk through one exchange without looking at the screen: learning that a message arrived, finding out who sent it, understanding what it says or shows, and replying. Note every step that assumes the user can see. ``` ### Clarifying Questions - Does "blind" mean no usable vision at all, or should people with low vision be included too? - Are the target users mostly blind from birth, or people who lost their sight later in life and may be new to assistive technology? - Is this a separate app with its own network of users, or can it reach the same contacts and chats as WhatsApp? ### What a Strong Answer Covers - A specific user group, defined by degree and onset of vision loss and familiarity with assistive technology, and why it was chosen - The core messaging journeys and the barriers each one poses without sight - How the design relates to the assistive technology blind users already rely on - How photos, videos and other visual content sent by sighted contacts become usable - A prioritized first release, success metrics, and risks specific to audio-first use ### Follow-up Questions - How would you involve blind users in research and testing, and what would you want to learn from them first? - The app describes a photo and the description is wrong. What should happen? - How would the design change for someone who is both deaf and blind?
