At beyond tellerrand Düsseldorf 2022 frontend developer and accessibility expert Manuel Matuzović gave this insightful - and genuinely funny - talk on web accessibility and in particular on how information often gets lost when web developers focus almost exclusively - to the exclusion of semantics and a design's intent - on the visual aspects while translating requirements into HTML and CSS: Read more

I see numbers

Metaphors play a vital role in how human beings make sense of the world. The ways in which we view and describe both the world around us and abstract thoughts often are inherently metaphorical. When relating to time, for example, we often use spatial metaphors such as "to look forward to", "time moving forward", or "to turn back time". For some though, relating to time in terms of spatial concepts and relations can take on quite a literal meaning. I've always visualised numbers, ... Read more

Welcome Back: beyond tellerrand Opening Titles Düsseldorf 2021

Last week, I was at the 2021 Düsseldorf edition of beyond tellerrand. As most on-site events during the last two years, beyond tellerrand had been postponed until, earlier this year, they got the go-ahead that the event was finally allowed to take place again. In spite of the rather short time to prepare, Marc and his team once again put on a fantastic event. These beautiful opening titles celebrate the event's return to the limelight with the simple, but very appropriate, words "Welcome ... Read more

User Experience Design Methods & Deliverables

As I previously wrote about, design and user experience (UX) design are disciplines defined and governed by rules, principles, and constraints. The highly recommended Laws of UX provides an in-depth overview of principles and best practices in UX design. Coming from a slightly more hands-on perspective, designer Fabricio Teixeira compiled a comprehensive list of UX design methods & deliverables such as service blueprints, personas, or user journeys.

Kennedy recently published an article with 15 Tips for Better Signup / Login UX on Learn UI Design - a website through which he provides acclaimed courses on both UI and UX design. The article lists general suggestions such as autofocusing on the first field (i.e. the username, or rather: email, field), immediately validating form values, or making input labels clickable, as well as more specific - but no less expedient - ones like making password requirements explicit to ...

Second-order Affordances: Design & Quantum Superposition

A few years ago, having read a thought-provoking article by Csongor Bartus I wrote about design & quantum superposition. The main idea behind this article, and my interpretation, is that - similar to a particle, which exists in a state of quantum superposition - a design doesn't exist by itself but can only ever be realised in a given context and at a specific moment through observation by a user and possibly a device that design is observed with. The gist, ... Read more

Lösung für die COVID-19 Pandemie: Schnelltests als Zugangsberechtigung

Sorry, this entry is only available in German.Contrary to my usual writing habits the remainder of this post will be in German. The reason for this is that although the subject most certainly is of interest to everyone the specifics of the solution outlined in the following mostly apply to the current COVID-19 situation in Germany and my personal experience with that situation. The article therefore is mostly relevant to a German audience. If you're interested in discussing the potential for ... Read more
