As a product designer at Sony, I worked on optimizing the user experience across multiple touchpoints in the Sony Reader ecosystem, including the e-ink Reader, tablet application, and the online store for web and mobile. The end goal was to create a cohesive and seamless experience across platforms for browsing, purchasing, and reading eBooks to drive engagement in the e-reader market. My deliverables included sitemaps, wireframes, black-and-white and full-color comps across various devices, as well as developing clickable web prototypes and comprehensive specifications and style guides. I conducted user testing to evaluate and refine user flows, particularly within the Reader store, to ensure a smooth and intuitive interaction throughout the ecosystem.
