Crowdsourced navigation platform Waze, which is owned by Google and yet remains a separate, but intertwined product relative to Google Maps, just got one of its biggest UI and design overhauls ever. The new look is much more colourful, and also foregrounds the ability for individual drivers to share their current emotions with Moods, a set of user-selectable icons (with an initial group of 30) that can reflect how you’re feeling as you’re driving.

Moods may seem like a relatively small user personalization option, but it’s actually a very interesting way for Waze to add another data vector to the crowdsourced info it can gather. In a blog post describing the feature, Waze Head of Creative Jake Shaw talks about the added Mood set, which builds upon the Moods feature previously available in Waze and greatly expands the set of expressible emotions.
