Originally developed by Toyota engineer Shigeo Shingo, the poka-yoke principle can be used in interaction design to help prevent users from making mistakes (avoiding dreaded error messages altogether.) Poka-yoke roughly translates to “error-proofing.”


Communicate the value of the poka-yoke principle to non-designers and budding designers through an animated video and mobile prototype.

A short, animated video that illustrates the principle on a conceptual level and a low-fidelity mobile prototype that showcases the tactical applications of the principle in UX.

the power of motion and time to tell a story

I decided not to do a voiceover for this video while the majority of my peers did. This decision pushed me to focus heavily on storytelling by guiding my character through an emotional journey. I also wanted to challenge myself to stay away from a digital narrative that only showed the technical aspects of poka-yoke.
