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/.

A mobile app that aggregates pricing data for video games to help the user find the best deal possible. This was created as a project for a class on prototyping techniques.

An extended collection of fully animatable UI libraries like triangles, stars, arrows and more, let you bring your idea to life all within Proto.io.

I simulated a 10 second timer that counts down from 10 to 0. This is very simple to do. All you need to do is change the text property of the text value with a custom value and include a delay of 1 second. Then add a callback for the next number with a delay of 1 second. Repeat this until you get to the number 0. There is no need to use variables to simulate a timer.

This one-screen prototype demonstrates some of Proto.io animation functionality.
