Halo – Open-Source Glasses Platform (brilliant.xyz)

Halo is an open-source smart‑glasses platform designed for makers, researchers and creators. The hardware pairs a micro color OLED POV display, optical‑grade lenses (including prescription/sunglass options), dual ultra‑compact bone‑conduction speakers, two mics with audio‑activity detection, an ultra‑low‑power optical sensor, 6‑axis IMU with tap detection, and Bluetooth 5.3. It runs an energy‑efficient Alif B1 SoC featuring a Cortex‑M55 CPU and NPU for on‑device AI, ZephyrOS with a Lua interface, a cross‑platform mobile app, and claims ~14‑hour battery life. Halo integrates with “Noa,” a cloud‑based AI agent for realtime multimodal conversations and persistent memory about what the device sees, hears and says; demo clips show applications like gardening help, sports coaching and contextual POI queries. For the AI/ML community this is notable because it combines low‑power edge ML (M55 NPU + optical sensor) with an open software stack, enabling experimentation with on‑device inference, sensor fusion and privacy‑sensitive workflows. Zephyr + Lua and the open hardware approach lower the barrier to building custom models, continuous personalization, and reproducible research in wearable multimodal perception. Tradeoffs to watch: offloading to Noa’s cloud agent boosts capability (persistent memory, complex reasoning) but introduces privacy and latency considerations. Overall, Halo is a practical platform for exploring lightweight multimodal agents, continual personalization, and novel edge/cloud co‑designs.
