Moen wanted to bring voice interaction into their U by Moen shower. They wanted the ability to use that interaction on any voice device, but not build the voice interaction into the shower itself.

What Can It Do
To understand what interactions needed to be the focus of this product, I determined what users might want to say to a voice-controlled shower. I accomplished this through brainstorming the common activities they might want to try.
UTTERANCE EXPLORATION: Exploring the voice interactions for an initial prototype.
Understanding the Process
Once I had a sense of what people might attempt to do, I mapped out different possible high level interactions.
HIGH LEVEL FLOWS: Understanding how the utterances will interact with the shower.
Action and Reaction
Once the high level flows were then confirmed with the client, I focused on capturing the exact type of interactions we would want to capture in a prototype to be used for research sessions.
ALEXA INTERACTIONS: Capturing the interactions with Alexa for the prototype.
Capturing the Interaction
I then took the suggested Alexa interactions and captured what exactly the shower display would do. This would be used in the implementation of the prototype for the research sessions.
U BY MOEN INTERACTIONS: More detailed interactions with the shower control for the prototype.
To truly capture how people would use this product, I needed to observe their process. But it would be very awkward to ask to observe people in the shower. So I created a setup that would mirror a shower with the U by Moen installed. I did this by:
- Using an iPad with a U by Moen prototype on it to create visual and auditory feedback
- Displaying U by Moen interfaces on the inside and outside of the shower environment to allow for the most popular set-ups
- Having white boards set up as to replicate a standard shower environment
I then asked participants that were recruited based on the likelihood of having such a product to walk me through a shower experience that they might have using an Echo with a U by Moen.
LAB SETUP: A wide-angle view of the room where the research occurred.
How People Actually Wanted to Interact
The research revealed two things:
- How people actually wanted to interact with the shower using their voice
- What people would really say to perform these interactions
This helped me capture what the true terms for people would want to use for interacting with the device. In addition, it provided feedback for the client as to what people wanted to say in order to activate the Alexa Skill.
UTTERANCES: The captured statements participants made during testing, and how they could be coded for the final prototype.
I took all of this feedback and created final diagrams for how a skill could be built for any voice-activated AI interfacing with the U by Moen. These became essential for building out the final prototype. I took these diagrams and worked closely with a developer to finalize an Alexa Skill prototype that we handed off to the client.
FINAL INTERACTION FLOWS: Capturing how Alexa or other A.I.s will respond to voice commands.
We know that this project was a success because Moen:
- Moved forward with our suggestion that they focus on the Alexa interaction, which became the initial launch of the voice interaction
- Gained media attention for the implementation at events like CES
- Implemented the interactions with Apple and Google products
