Moen

Voice Design

Overview

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.

The Problem
How could we bring a voice interaction into a shower with a device that is not attached to the shower? What is the likelihood that users would actually interact with the shower via voice?
My Contributions
  • Lead interaction designer and user researcher
  • Prototype design
  • Participant recruiting
  • Session structure, including lab setup and script
  • Interaction flows for multiple devices
Challenges
  • Identifying the interactions
  • Capturing a shower experience without the shower
  • Identifying terms for the interactions
  • Creating the final deliverable

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.

Voice Commands Exploration

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

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

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

U BY MOEN INTERACTIONS: More detailed interactions with the shower control for the prototype.

Lab Research

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:

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

LAB SETUP: A wide-angle view of the room where the research occurred.

How People Actually Wanted to Interact

The research revealed two things:

  1. How people actually wanted to interact with the shower using their voice
  2. 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.

Utterance Patterns

UTTERANCES: The captured statements participants made during testing, and how they could be coded for the final prototype.

Interaction Diagrams

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 Flow

FINAL INTERACTION FLOWS: Capturing how Alexa or other A.I.s will respond to voice commands.

Outcome

We know that this project was a success because Moen:
