Cirrus is an IoT home monitoring device, which allows users to unlock multiple doors and other locked objects with a wearable ring. This product-ecosystem includes the ring which acts as a master key, a mobile app, and specialized locks.

Project Brief

The requirement of this project was to craft an overall experience for the end user, not only in the digital form but in the physical as well.


The challenge was to lead users to actions that advanced the experience and narrative.


Students were asked to choose to design a home monitoring device, a boxed food experience, or a modification for personal mobility.

Project Information


Class: Behavior​

Instructor: Peter Stahl

Duration: Four weeks

Key Skills: Video production, storyboarding, writing, design research, visual design, digital prototyping, and physical prototyping​


Tools & Materials: Adobe Illustrator, Premiere, After Effects, video camera, hole saw, spray paint, foam, tungsten, and aluminum

Project Role: Individual project

  • Physical materials that constitute the envisioned experience, manifesting in a high-fidelity prototype that looks and feels like a finished product.


  • An on-screen prototype that navigates users through an out-of-box-experience narrative.

  • A short video (1-2 minutes) that documents the final envisioned experience and how it facilitates desired behavior change. This will serve as a stand-alone communication of the value of the design.

Design Research

Interviews, Insights, and Opportunities 

Prior to prototyping, I interviewed 39 individuals and had them tell me about their daily interactions with their keys. I wanted to know how they used them on a regular basis to help gain some insight into their points of frustration and delight.

After categorizing key insights and grouping them, I entered them into a spreadsheet by their respective classifications, which included:

  • Relationship and interaction between keys

  • Enjoyable aspects

  • Pain points

  • Desired changes


Affinity mapping insights gained from participants
