On the LIRAVA smart-glasses platform
A second pair of eyes, in any weather.
SpecialAssist guides blind travellers across indoor halls, sidewalks and streets — through rain, night, storm or tornado — and describes the world out loud, calmly, the moment it's asked.
"Front door ahead, 4 meters. It opens toward you."
"Bus stop 15 meters ahead on your right. A bench is beside it."
"Car from your left — hold here."
"A free table to your right, two steps. A chair is tucked under it."
"Bus 42 to Downtown is arriving."
The problem
Getting around shouldn't depend on the weather.
A white cane and a guide dog reach only a step or two ahead. Most smart aids lean on cameras alone — and fade in rain, fog and darkness. The gap is widest precisely when the world is hardest to read.
Who we design for
"I don't want to be guided. I want to know what's there, and decide for myself."
Maya commutes to work, runs her own errands, meets friends for coffee. Independent — and tired of routes that only work in good weather. What earns her trust: calm, accurate, hands-free — and honest when it's unsure.
The idea
Two jobs, one pair of glasses.
Take me anywhere
Real-time, all-weather navigation indoors and out — with spatial audio and haptics, completely hands-free. You walk at your own pace; guidance stays calm and sparse.
Tell me what's there
On-demand scene description — people, doorways, free seats, text and signs — read aloud in plain language, only the part that matters, the moment you ask.
How it works
From sensor to spoken word.
Safety-critical perception runs on the frame itself, in under 50 milliseconds — no waiting on a network when a step matters.
Sensors
LiDAR, cameras, motion sensors and mics read the scene.
Fusion
Filter, de-noise and map — millions of points become a clean picture.
AI perception
Obstacles, scene and a walkable path, recognised on-device.
Decision
Weather, context and priority decide what to say — and what to hold.
Audio out
Spatial sound, haptics and one calm voice — ears stay open.
All-weather resilience
It adapts as conditions turn.
The decision layer changes which sensors it trusts — so navigation never goes dark.
Clear
The full sensor suite runs, for maximum accuracy.
Rain & fog
Radar and filtered LiDAR take over from cameras.
Night
LiDAR plus infrared see clearly in the dark.
Storm
Alerts fire; it guides you to the nearest shelter.
When the storm hits.
A weather alert arrives over cellular. SpecialAssist drops everything else, pulls the alert, and becomes a single-minded guide to the nearest safe shelter — narrating every step.
The one rule
One voice, never crowded.
Three channels, strictly ranked — so the important thing is always the thing you hear.
Interrupts everything
Hazards cut in instantly, the moment they appear.
"Car from your left — hold."
Only when needed
Turn-by-turn cues, never chatter for its own sake.
"Bear right at the corner."
On demand
The rich description of the world, when you ask for it.
"A warm room, a dozen people."
The platform
The hardware you already have.
Every component on the LIRAVA frame already feeds the system — nothing extra to carry.
