Trio 8300

UI and GUI design for Poly's Trio 8300 — a button-interaction conference phone with a 2.5" screen, extending the touch-based experience of the Trio 8800 to a smaller, simpler device while keeping the Poly identity intact.

Overview

The Trio 8300 needed its own UI and GUI for a button-driven, 2.5" screen — designed so the interaction model still felt like family to the touch-based Trio 8800, without borrowing a touch interface the hardware couldn't support.

Keeping a family feeling across form factors

The real constraint wasn't the smaller screen — it was making a button-driven device feel like it belonged to the same family as its touch-based sibling, without pretending it had touch capabilities it didn't.
