Third Eye Kit
A three-part wearable navigation system: glasses for upper-body obstacles, shoes for ground-level hazards, and gloves with ultrasonic sensors for stairs and surfaces. GPS, fall detection, emergency alerts, all on 2G. Roughly $50 to build. Best Presentation Award, TEKNOFEST Black Sea 2022.
What it is
What is it?
The Third Eye Kit is the organization's first deliverable and its most thoroughly tested one. Three integrated components — glasses, shoes, gloves — each handle a different layer of the navigation problem.
Glasses detect upper-body obstacles: tree branches, signs, doorframes, people walking toward you.
Shoes detect ground-level hazards: curbs, holes, steps, objects underfoot.
Gloves carry ultrasonic sensors for navigating stairs, sensing surfaces, and reading terrain by hand — the user climbs by feel, not faith.
All three components connect to GPS. Live location is transmitted to family or caregivers. The kit detects falls and physiological distress and sends emergency alerts when something goes wrong. It works on 2G networks, which means it works in rural villages, dense urban environments, and anywhere in between. End-to-end build cost is roughly fifty dollars.

How it works
How does it work?
Each component carries a small set of ultrasonic distance sensors and a microcontroller. Distance readings translate into vibration patterns the user learns over a short training period — closer obstacles produce stronger, faster pulses; clear paths produce nothing. The components communicate over Bluetooth and connect through a paired phone for GPS, alerts, and remote monitoring.
The system is deliberately low-fidelity. There is no camera. There is no machine-learning model running in the cloud. The kit works offline, works on old hardware, and works in places where any of those dependencies would fail. The intelligence is in the design, not in the silicon.

The reason
Why we built it
Mainstream assistive technology assumes a user with money, infrastructure, and access to expensive devices. The Third Eye Kit is built on the opposite assumption: that the people who need this most are the ones the rest of the industry hasn't reached. ~$50, 2G, open-source. Independence shouldn't have a price tag, and where it does, the tag should be small enough that no one is excluded.
In practice
How is it used?
A user puts on the three components and pairs them with a phone. The kit calibrates to the user's gait, height, and stride during a brief setup. From there it operates passively — no buttons to press, no commands to issue. Vibrations on the gloves, shoes, and glasses tell the user what's around them. The phone handles GPS and emergency comms in the background.
A trusted contact (family member, caregiver) receives live location and an alert if the system detects a fall or physiological distress. The user controls who sees what.
We've tested the kit in real-world conditions across multiple countries — different terrains, different climates, different sound environments. The same device behaves differently in every place. Walls echo at different pitches. Hallways have different widths. Streets have different textures. Invention only succeeds when it listens.

What’s next
What’s the future of it?
Three priorities. First: a manufacturing partner who can produce the kit at the $50 target price at volume, so we can distribute it free or near-free to users who can't pay. Second: a training curriculum delivered through the upcoming Third Eye University so users learn the kit on day one, in their own language. Third: open-sourcing the full build — schematics, firmware, training materials — so any community anywhere can manufacture locally.
The award is not the goal. The goal is that no one has to wait for the world to remember that good navigation tools should exist for everyone.
