From Berlin to Tokyo: Designing Interfaces That Cross Cultures and Generations
Talk Synopsis
What if your “universal” UI isn’t universal at all? In this talk, Guillaume reveals surprising findings from a cross-cultural, cross-generational study comparing how users in Japan and Western Europe interact with the same everyday interfaces.
From contact forms to checkbox labels, we’ll unpack the subtle ways culture and age shape trust, usability, and conversion.
With vivid real-world examples and practical design takeaways, this session challenges default assumptions and equips you to design with clarity for diverse, global audiences.
If you’re building products beyond your bubble, this talk will sharpen your instincts, and your interfaces.
