In the first version, all controls sat directly on the output screen - causing visual clutter and breaking the reading flow. I solved this by moving secondary actions into a “More Options” menu, reducing overload while keeping advanced controls instantly accessible.

User research was crucial for this project. Testing revealed that the first design caused cognitive overload. After simplifying the interface, 7 out of 10 participants said it felt calmer and easier to read.
The core lesson: simplicity isn't about fewer features, but about removing distractions to create inclusive, human-centered dei

The next step for Lexi is personalization: allowing users to save preferred font size and reading speed. I would also run usability tests with a broader and more diverse group to validate assumptions and uncover new accessibility needs.
