Walking guidance that speaks in steps.

Shravan is a walking guide for blind and low-vision people. A phone and one earbud tell you the next move, counted in your own steps. Then it checks that you made it.

02Hear a walk

Twelve steps on an Indian footpath.

  1. Shravan

    “Pothole, three steps ahead. Space on your left.”

  2. You

    You step left.

  3. Phone

    The motion sensors confirm the step.

  4. Shravan

    “Left is clear. Continue.”

One instruction at a time. Nothing new until the last one worked.

03The problem

Every walk is a chain of decisions.

Today a blind walker pieces each decision together from several tools. Each one knows part of the picture. None of them knows whether you acted on what it said.

  1. The white cane

    Knows
    The ground about a metre ahead.
    Misses
    A road from a footpath.

    Checks you acted · No

  2. A GPS app

    Knows
    The map.
    Misses
    The pothole in front of you.

    Checks you acted · No

  3. A vision app

    Knows
    What the scene looks like.
    Misses
    Where you should step.

    Checks you acted · No

  4. A stranger

    Knows
    The street, when you ask.
    Misses
    You have to ask, and then wait.

    Checks you acted · No

  5. Shravan design goal

    Knows
    The next safe move, counted in your steps.
    Misses
    It does not replace the cane. The cane stays.

    Checks you acted · Yes, with the phone’s motion sensors

A map speaks in metres. A walker counts steps.

04What you carry

A phone, one earbud and the cane you already trust.

That is the whole first version. A chest camera, an open earpiece and a shoe clip come later. Yellow tags mark the first version; black tags come later.

First version

  1. 01Your phone. Reads your steps with its own motion sensors and does the thinking.
  2. 02One earbud. One short instruction at a time. The other ear stays on the street.
  3. 03Your white cane. It stays. Shravan adds what lies beyond the first metre.

Comes later

  1. 04Chest camera. Reads the surface, free space, obstacles, people and vehicles.
  2. 05Open earpiece. Instructions without blocking street sound.
  3. 06Shoe clip. Learns your stride, pace and turning in the first 5 to 7 days. Then it comes off. The profile stays.

Then it closes the loop.

Other tools speak and move on. Shravan waits until your step confirms the last instruction, then gives the next one.

05Safety

It sheds intelligence, never safety.

As the battery runs down, guidance steps down with it. Three things never switch off.

On at every level

  • Fall detection
  • SOS
  • Location sharing
  1. 100–40%Full guidance.

    Everything on.

  2. 40–20%Lighter.

    Footpath detection only.

  3. 20–10%On demand.

    Navigation and safety always on.

  4. 10–5%Safety mode.

    Fall detection, SOS, location and trusted contacts.

  5. Under 5%Last word.

    It announces its state, sends the last location and keeps SOS alive.

If you fall.

  1. 01Shravan asks

    “Are you okay?”

  2. 02No answer?

    It opens live audio.

  3. 03Your people know

    Your location goes to the people you trust.

It never calls the police or a hospital on its own.

06Evidence

A trial has already shown that a phone can guide a blind walker.

13%
less time on the outdoor route
41%
fewer contacts with obstacles on the indoor route

Bars indexed so the cane and Google Maps equal 100.

Shravan builds on the same idea and goes past the end of the path: the fall, the ride, the person walking toward you, the phone at 8%.

10Questions

What people ask.

What is Shravan?

A walking guide in design for blind and low-vision people. A phone and one earbud give one instruction at a time, counted in your steps, and check that you moved before the next one.

Can I buy it?

Not yet. Shravan is a concept in design. Join the first walkers to hear when trials start.

Does it replace the white cane?

No. The cane stays. Shravan adds what lies beyond the first metre.

How is it different from a smart cane?

A smart cane warns about an obstacle. Shravan picks the next move, says it in steps and checks that it worked.

What will it cost?

The planned price is Rs 7,500 to Rs 12,999, inside the ADIP limit of Rs 15,000. Once Shravan is an approved aid, an eligible user would pay nothing.

Does it need the internet?

It is designed so that steps, route, fall detection and SOS work with no network. The optional cloud is used only when you ask for it, and never in the safety path.

Who is building it?
