About the event

By now, Accessibility Club Hamburg has become a bit of a habit — and we couldn't be happier about it. What started as the northern chapter has turned into a regular meeting point for everyone who cares about accessible digital products: developers, designers, writers, testers, product folks, and anyone who's simply curious. The format stays exactly what it's always been: informal, with a few informative speaker slots and plenty of time to mingle, chat and swap experiences.

Our first two Hamburg meet-ups in September 2025 and January 2026 filled the room — with great talks, a fantastic view over the city's rooftops, and conversations that carried on long after the last slide. On September 23rd we're doing it all again, and we'd love for you to be there. No expertise required, no need to know anyone beforehand — just bring your curiosity. See you in Hamburg!

Presentation title: Missed & Clicked Away: How we design toasts, snackbars, and other messages to be more user-friendly

When status, success, and warning messages disappear, many users lose critical information — even if they clicked them away themselves. Standard specifications and common time formulas often fall short here. Based on studies and insights from usability tests, Nina Gerling will give you an initial insight in this short presentation into how you can adapt notifications to the actual behaviors and cognitive challenges of people in all their diversity.

Presentation title: Color contrasts and tooling for screen, print and hardware

In this absolutely improvised session, Nina and Joschi will share some of their insights from working with colors and contrasts across different media — both digital, such as web and documents, and analog, such as print and hardware. They will play around with Joschi's recently released contrast tool, Pairette, and show you what is possible with it. Nina will bring a colorimeter and sample devices so that you can try for yourselves how to measure and evaluate colors on objects. Please don't expect a polished presentation, but perhaps a few "Ahas" and "Ohos"!
