Dex turns real-world moments into language lessons for kids 3–8. Instead of passive screen time, Dex invites kids to notice the world around them and talk back to it, transforming routines into learning opportunities. The result is a gentle rhythm of daily speaking, listening, and discovery that feels like play but compounds into real progress.

Industrial design
We collaborated with XIVO Design to create device shaped like a handheld magnifying glass with a camera on one side and a multi-touch screen on the other. Two tactile buttons keep controls simple: one to confirm, one to cancel. The device also includes a microphone, speaker, and accelerometer. Unlike tablets that encourage passive sitting, Dex's form factor invites children to hold it and carry it during active exploration—transforming how they engage with their environment.

Product photography
Using Google Gemini 3, we were able to create a unified visual language for ads, packaging, and the website. The images kept the device shape, colors, and proportions stable while letting us swap families, moods, and settings so every photo felt real and part of the same world.

Character Design
Children learn best when they connect with a character. We partnered with The Little Labs to design a friendly elephant who guides each activity and appears across our stories. The character greets kids, models tasks with simple cues, and celebrates progress with animations and audio. Consistent personality, voice, and pacing help build trust, so practice feels like a narrative that kids can follow and enjoy.

Audio Feedback
Our character responds to every pronunciation attempt by scaling from micro-reactions to full reward moments, while sound design shifts from gentle guidance to triumphant stingers. Together, the motion and audio create a loop that’s instantly understandable, playful, and measurably effective.

Interactive Nav
We developed high-fidelity prototypes to explore an interactive navigation system that would resonate with children by being both engaging and easy to use. These prototypes featured exposed sliders and customizable settings, giving the team the flexibility to test different configurations in real-time.
