VEE Wear UI/UX Demo on ATS3085S: App Samples, Video Decoder & Facer Integration

High-performance, visually rich smartwatch experiences are no longer the privilege of premium hardware. This demo showcases VEE Wear, MicroEJ’s compact wearable OS, running on the Actions ATS3085S/E SoC, a cost-effective MCU-based platform designed for mass-market smartwatches.
 
From smooth animations and fitness tracking apps to MCU video decoding and Facer watch face synchronization, this video demonstrates what embedded GUI excellence looks like on affordable hardware.

What This Demo Covers

In just over three minutes, this demo highlights three core capabilities of VEE Wear on the Actions ATS3085S/E SoC:

• Wearable UI app samples: fitness tracking, timers, weather, and training metrics powered by vector graphics and smooth animations
• Video Decoder for MCU playback: fluid motion design decoded entirely on the MCU, without a dedicated media processor
• Facer integration: seamless watch face pairing, catalog browsing, and syncing directly from the Wear Companion app

Rich Wearable UI Experiences on MCU-Based Hardware

VEE Wear’s embedded GUI stack enables manufacturers to deliver smartphone-like visual experiences on resource-constrained devices. This demo features a curated set of wearable app samples, including:

• Fitness tracking with heart rate monitoring and activity metrics
• Timer and stopwatch applications with animated interfaces
• Weather apps with dynamic visual feedback
• Training screens displaying average speed, distance, and performance data

All interfaces are rendered using vector graphics and optimized animations, maintaining smooth, responsive behavior while keeping power consumption under control.

Video Decoder – Motion Design on the MCU

One of the standout capabilities demonstrated in this video is MCU-level video decoding. The “Rabbit” motion design sequence plays back smoothly on the Actions ATS3085S/E, with no dedicated media hardware required.

This opens new possibilities for wearable manufacturers looking to differentiate their products through animated branding, onboarding experiences, or rich visual feedback, all without adding silicon cost.

Facer Integration – 500,000 Watch Faces on Any Smartwatch

This demo also showcases the full Facer integration workflow on a VEE Wear device:

• Quick pairing via the Wear Companion app on a smartphone
• Catalogue browsing directly from the Facer library of over 500,000 watch faces from 40,000 designers
• One-tap sync of a chosen watch face, including the Arcade Showdown face, a Facer official Street Fighter collaboration, directly to the smartwatch

With VEE Wear and Facer, manufacturers can offer their users the same level of personalization available on leading wearable platforms like WearOS or watchOS, at a fraction of the hardware cost.
