Built by one person, for the road ahead.

HALO is an independent project by Guillermo Alarcon — a developer and creator based in Tokyo, building for the next generation of wearable displays.

The movies promised us a future where information just appears in front of us — directions floating over the street, no phone in hand, eyes up and on the world. When the Meta Ray-Ban Display glasses arrived, that future finally had a place to live. HALO started as a simple question: what if turn-by-turn navigation lived right in your glasses, clean and glanceable, instead of buried in your pocket?

So I built it. HALO brings turn-by-turn navigation, place search, a glanceable speedometer, and a heads-up view to the glasses, powered by Google Maps. Every build is tested on real hardware, on real streets here in Tokyo — not just in a simulator. If something feels off while you're moving, it gets fixed.
