My first instinct was to just list features like audio feedback and tactile controls, but that felt shallow pretty fast.
Start by clarifying the user's needs and the constraints of the problem, then structure your answer around a user-centered design process. Focus on how you would adapt the iron's design to be usable without sight, emphasizing safety, feedback mechanisms, and accessibility. Conclude by discussing how you would validate the design with blind users and iterate.
Pro tip: Demonstrate empathy by considering the entire ironing workflow, not just the iron itself, and mention specific assistive technologies like tactile indicators or audio feedback. Also, highlight the importance of co-designing with blind users to avoid assumptions.
Ask questions to understand the user's context, such as their level of vision, ironing habits, and safety concerns. Define the scope and constraints (e.g., budget, existing technology).
Brainstorm the key challenges a blind user faces when ironing, such as detecting heat, water level, and fabric type. Prioritize needs like safety, independence, and efficiency.
Propose design features that address the needs, such as tactile controls, audio alerts for temperature, and sensors to detect fabric. Consider both hardware and software integration.
Describe how you would create low-fidelity prototypes and test them with blind users. Emphasize iterative feedback and accessibility testing.
Outline metrics to evaluate the design, such as task completion time, error rate, and user satisfaction. Discuss how to measure safety and independence.
