Pixel Watch — Tri Nguyen

The Problem

The smallest surface, the least room for ambiguity

A watch has no room for a contact list, a keyboard, or a long confirmation screen. Every comms interaction — calling, messaging, safety features — had to resolve almost entirely through voice, with the display used only to confirm, not to choose from.

My Role

Outlining the key flows for a multi-year launch

Pixel Watch was a multi-year effort from concept through detailed design and quality testing. I iterated on calling, messaging, and safety Assistant CUJs, was responsible for outlining the key flows, and helped lead the other designers through the launch.

Key Decisions

An 8-step voice-first system, annotated end to end

Every message flow — greeting, input, disambiguation, follow-on, verify, sending, sent — mapped as one continuous voice-first system, not a series of disconnected screens.
Confirmation states designed to be glanceable: a checkmark and an earcon, not a paragraph of text, tell you a message sent.
The same confidence-tiered disambiguation logic from the broader Comms UX Framework, adapted for a round face and voice-biased input.

Impact

A shared communication framework brought to the wrist

The work supported the shipped Pixel Watch launch, carrying calling and messaging flows from concept through detailed interaction design and quality testing. I outlined the key flows and helped guide other designers through the multi-year effort.

Adapting the broader Comms UX Framework for Wear OS established how voice-first communication could work on a small, round display. The annotated flows gave the team a shared reference for disambiguation, confirmation, and message delivery across the complete interaction.

These are delivery and system-level outcomes. I don't have verified adoption or usage metrics to report.
