Concept story • LifeLens

Walkthroughtheworld,
evenwhenyoucannotseeorhearit.

Close your eyes for ten seconds and try to cross a busy road. This is the starting point of LifeLens — a concept for AI-powered goggles that could quietly describe the world and caption voices in real time.

“Before, every crossing felt like a calculation of risk. With LifeLens quietly describing the world to me, I feel like the city finally wants me here.” — imagined blind user

Chapter 1 — Why this matters

Every number here is a street, a family, a life interrupted.

Annual deaths

0+

road deaths every year worldwide

Vision

0B

people living with vision impairment or blindness

Hearing

0B

people living with hearing loss

Chapter 2 — The street view

Instead of slides, here is the news feed of their day.

Blind men guiding each other across a chaotic city road
When one person without sight leads another, a single mistake can hurt all of them.
Group of blind people crossing a busy road with help from others
Every crossing is a negotiation with traffic, noise, and trust in strangers.
Blind man with white cane alone at a crossing
Alone at the curb, waiting for a gap in sound that might not be safe.
Deaf woman signing intensely during a conversation
For deaf people, even a simple sentence can become hard work to follow in a noisy world.
Blind men with white canes navigating traffic together
Side by side with traffic, one missed horn or broken signal can change everything.
Group of deaf school children signing together
In deaf schools, whole classrooms speak in their hands—while the outside world rarely answers in the same language.

Chapter 3 — Two imagined days

Before and if LifeLens existed.

Ayaan's view — Blind user
Before

Counting steps, memorising cracks in the pavement, hoping no bike was parked in his path today.

Turning point

One night, the sounds at a crossing blurred together — horns, music, shouting — and he froze on the edge.

If LifeLens existed

In our concept, LifeLens whispers: “Zebra crossing in 3 metres, car from the left, your friend Rahul ahead.” The city becomes information, not fear.

If LifeLens existed

Arjun's view — Deaf user
Before

In class, Arjun watched lips and guessed the missing words, laughing a beat late when everyone else did.

Turning point

When an alarm rang behind him, he only understood when he saw people stand up and run.

If LifeLens existed

In our concept, captions float on his lens: the teacher’s explanation, the joke, the words “I’m proud of you.” The alarm flashes as text before panic spreads.

Chapter 4 — The concept

A quiet companion that sees and listens for you.

LifeLens is currently a concept — a pair of AI-powered smart goggles that integrate computer vision, distance sensing (ultrasonic), motion detection (MPU6050), speech recognition and text display, with real-time processing on a Raspberry Pi. The device could detect obstacles, read text, caption speech, and keep loved ones informed when something goes wrong.

Eyes

Camera + AI that spots obstacles, cars, crossings, friends, doors, and text.

Ears

Speech-to-text engine that could place live captions on the lens for deaf users.

Safety net

If someone falls or stops responding, GPS and last image could notify family or helpers.

Chapter 5 — Our early sketches

Hardware concepts for blind and deaf users.

These are not finished products — they are prototype ideas we explored while thinking about how LifeLens could live on a real pair of goggles.

LifeLens Blind Version prototype: Camera, Ultrasonic Sensor, Raspberry Pi Zero W2, Speaker, Microphone, GPS Module, MPU6050, Battery

Blind version

Camera, Ultrasonic Sensor (HC-SR04), Raspberry Pi Zero W2, speaker, microphone, GPS module, MPU6050 motion sensor and battery for obstacle detection, navigation and fall-detection alerts.

LifeLens Deaf Version prototype: Camera, Sound Sensor (mic), Raspberry Pi Zero W2, Transparent Display, GPS Module, MPU6050, Battery

Deaf version

Camera, sound sensor (mic), Raspberry Pi Zero W2, transparent display, GPS module, MPU6050 and battery for live captions and safety alerts.

LifeLens is still an idea. But the lives it could touch are very real.

This site is our way of telling their story for the hackathon — connecting real struggles to a concept that could one day help blind and deaf people move through the world with more confidence.
