Designing an Accessible Cash Machine for Blind and Low-Vision Customers

Design an ATM that people who are blind can use on their own. Decide which users and which parts of the experience you would focus on, propose your design, and explain how you would judge whether it works. ```hint Walk the visit end to end Trace one cash withdrawal from finding a machine to walking away with the money, and ask at each step what someone who cannot see the screen does today. ``` ### Clarifying Questions - Am I working for a bank or ATM maker that controls the hardware, or can I change only software, for example by connecting the machine to the bank's phone app? - Is the first release limited to cash withdrawal, or must deposits, balance checks and transfers work too? - Should I design only for people who are fully blind, or also for low-vision users and people who are both deaf and blind? - Which country is this for, given that accessibility rules and banknote designs differ from one country to another? ### What a Strong Answer Covers - A chosen user segment and goal, with the reason other segments come later - The withdrawal journey step by step, with the problems specific to not seeing the machine: finding the slots, navigating menus, entering a PIN privately, knowing which notes came out - Prioritized solutions that work without sight and do not rely on braille alone, building on what accessible machines already offer - Privacy and safety against onlookers and theft, plus spoken recovery from errors - Success metrics such as unassisted completion and time on task, and a plan to test with blind users ### Follow-up Questions - Many blind people, especially those who lost their sight later in life, do not read braille. How does that change your choice of inputs and outputs? - Banks will not replace their existing machines quickly. How would you bring the design to machines already in the field? - What would you change for a customer who is both deaf and blind?
