Accessible clothes iron for blind users: needs, safety-first features and validation

Design a clothes iron for someone who is blind. Explain whom you are designing for, how ironing works for that person today and where it goes wrong, which features you would include and in what order, and how you would tell whether the design succeeds. ```hint Walk the task without sight Go through ironing one shirt from start to finish, from filling the water tank to putting the iron away, and mark every moment that normally depends on seeing something. ``` ### Clarifying Questions - Is the user fully blind or do they have some usable vision, and did they lose their sight recently or long ago? - Is this a specialist product for blind users or an accessible version of a mainstream iron, and what price range should it hit? - Must it be a traditional iron used on a board, or is another form, such as a garment steamer, acceptable if it meets the need better? - Can it depend on a smartphone app, or must every core task work on the device alone? ### What a Strong Answer Covers - A precise user definition that separates kinds of vision loss and braille use, and a step-by-step view of ironing that flags each moment that relies on sight - Safety (burns, scorched fabric, an iron left on) treated as the first priority - Non-visual feedback through touch, sound and vibration, with features prioritized and trade-offs on cost and complexity stated - A validation plan with blind participants that defines success and how it is measured - Whether to sell it as a specialist device or build it into a mainstream line, and how blind users take part in the design ### Follow-up Questions - How would you test the design before mass production, and what result would make you change course? - If the budget allowed only one non-visual feature, which would you keep, and why? - How would sighted buyers react to these features in a mainstream iron, and would that change your design?
