An Interaction Prototyping Designer who believes products should be meaningful with loops of surprise and delight, previously at Waymo, Google, and Pinterest.

At ArtCenter working on my thesis: AR, AI, and motion interface. Looking at some new cognitive interfaces concepts too.


I'm Zhendong Li, but I go by Justeen Lee. With a firm vision of harmonious integration of hardware and software, I define, visualize, and prototype interactions between humans, interfaces, devices, and systems, via series of motion studies, arrays of sensor I/O's, and lines of code. Then I bring aha moments to people around me.
