Happy ‘first Friday of summer’ everyone! This week I’ve got a concise but valuable piece on the value of digital prototyping, an article highlighting a study on voice-first user interfaces (Siri, Echo etc.), and some tips on improving UX for colour-blind users. The prototyping article from Headscape is particularly relevant to me as it’s something we practice religiously at ResIM. Rounding things out this week is a post I wrote earlier this year on business rules and how they affect UX. Enjoy!
