Glue: Spotify’s Design Language

Glue stands for Global Language, Unified Experience. It refers to the team that manages Spotify’s Design Language, which I joined from the very beginning. We set out to maintain a cohesive, scalable and world-class user experience across all platforms on which Spotify was available.
We supplied the teams with toolkits and guidelines, and worked closely with engineering to create a robust library of components and interactions all consistently aligned across all platforms. Our team grew from 4 designers to around 25 designers, testers, developers and managers. With this team we kept updating our design language on all levels: visual designs, cross-platforms interactions and even strategy.

Now Playing View

When Spotify introduced podcasts and video shows, the Now Playing View required an update to support all new formats. We took advantage of this opportunity to improve this view’s clarity and scalability.
Based on the data collected of passed Now Playing Views, we prioritised the different actions based on need. The structure of the view follows the route the content takes from top to bottom. First you read what context you’re playing, followed by the actual song or video in that context. Further down you can see where exactly in the song or video you are. And lastly, the bottom of the view tells you where the audio is playing: either on your own device or an external device. The layout was optimised to scale to different screens, taking advantage of extra space where needed.Today the Now Playing View is visible on all mobile platforms.

Spotify Search

Spotify’s Search Experience was redesigned to take advantage of the new search engines the engineers had built. These engines were able to provide better and faster results, suggestions and corrections. The new design therefor embraced instant results and corrections. Matching characters are highlighted and the results are ordered based on most frequently searched content types. Since Search was one of the most frequently used features at Spotify, we started with a gradual rollout on iOS. After initial tweaks and fixes, the results were very positive. We continued rollout to Android and adapted the desktop search experience to follow a similar flow.

OFFF App 2012

Each year the OFFF Festival brings together a large community of creatives to enjoy lectures of inspiring motion graphic designers, illustrators, advertising agencies and production companies. The app created for OFFF 2012 tried to take another spin on a calendar. Through a circular interface, you could switch between dates and speakers.
By pulling a section out, you could read more and potentially save it as a favourite. The entire app was coded in HTML5, working cross-platforms and offline. This project was done in a small team where I was responsible for the information architecture and coding the final product. Design was done by Matilda Dackeval.
