Hi there! The Search Project is my latest prototype that allow users to search images and have live results. Happy prototyping!

This is a prototype that demonstrates you some of the capabilities of Proto.io. You are welcome to import this project and use these interactions in your prototypes. In this prototype you will see swipe animations in all directions.

This is a UX design prototype for Pandora's Android app (from October 2014), adding a "Driving Mode" and lateral navigation between stations from the Now Playing screen. I took a challenge to redesign Pandora's Android app or add features at my discretion. Focusing on the Now Playing screen where users probably spend most of their time, I identified two areas in which I wanted to improve its UX: station identification and navigation, and its user experience while on the go. A 7 minute 25 second presentation of this demo with commentary is available on YouTube: http://youtu.be/LyH6Gl580OY A full write-up of an earlier, pre-Proto.io iteration of the design (along with a downloadable pdf) is available at http://edwinli.com/ux/portfolio/pandora-driving-mode/.
