Design a calculator for the blind.

Introduction

Designing a calculator for the blind presents a unique challenge that requires us to rethink how we approach user interface and interaction design. We need to create a tool that's not only functional but also intuitive and accessible for visually impaired users. I'll outline my approach to this problem, focusing on user needs, technological possibilities, and potential solutions.

Step 1

Clarifying Questions (3 minutes)

• Based on the problem description, I'm thinking this might be for a specific company's existing product line. Is that the case, or are we approaching this as a standalone product?

Why it matters: This helps frame the solution within existing company constraints or as a new market entry. Expected answer: It's a standalone product. Impact on approach: We'd need to consider building from scratch, including branding and market positioning.

• Given the specialized nature of this product, I'm assuming we're looking at a focused tech company rather than a large, diversified one. Is that correct?

Why it matters: It influences our resource allocation and go-to-market strategy. Expected answer: Yes, it's a focused tech company specializing in accessibility products. Impact on approach: We'd leverage specialized expertise but might have limited resources.

• Are there any specific time or budget constraints we should be aware of for this project?

Why it matters: It helps prioritize features and set realistic development timelines. Expected answer: We have a 12-month timeline and a moderate budget. Impact on approach: We'd focus on core features first, with a phased rollout plan.

• Has any user research been conducted with visually impaired individuals regarding their calculator needs?

Why it matters: Existing research could inform our initial design decisions. Expected answer: Some preliminary research has been done, but it's not extensive. Impact on approach: We'd need to conduct additional user research to validate our assumptions.

Propose the Goal

Given our focus on accessibility technology, I believe our goal should be to create an intuitive, easy-to-use calculator that empowers visually impaired users to perform calculations independently and efficiently in various settings. Does this align with your vision?

Define the Scope

For this product design challenge, should we focus on a handheld device, or are we open to exploring other form factors like smartphone apps or desktop solutions?

Based on your answers, I'll assume we're designing a standalone handheld calculator device for visually impaired users, with a 12-month development timeline and moderate budget. We'll need to conduct additional user research to inform our design decisions.
