2 – The Voice Interface

An AI voice app for the visually impaired, blind, and dyslexic like Lumyeye transforms a smartphone into an intelligent personal assistant, capable of describing the environment, reading texts aloud, and answering questions, without ever requiring tactile interaction. It is primarily aimed at people who are blind, visually impaired, or have a visual impairment, but can also benefit seniors or anyone with reading difficulties.

Unlike traditional applications that require touching the screen or using a mouse, a voice application for the blind is controlled solely by voice. The user dictates a command such as:

=> "Read me this bill."

=> "Tell me what's in front of me."

=> "What products are visible in this department?"

The application recognizes the voice, interprets the request and activates the correct function (taking a photo, reading, searching, etc.).

It was in our initial specifications, we didn't want any user manipulation, even when launching the application, just say "hey siri" or "OK google" to launch it.

3 – Intelligent Photo Capture

One of the app’s standout features is voice-guided photo capture. The user asks a question, the camera automatically takes a picture, and the image is analyzed by artificial intelligence.

It can identify:

  • Objects (e.g., glasses, keys, bag)

  • Documents (invoices, letters, bank statements)

  • Printed or handwritten text

  • Signs and directions (street, subway, store)

  • The contents of a fridge—or essentially anything placed in front of it!

The information is then delivered aloud, either as a word-for-word reading or as a smart summary, with the option for further interaction.

This means the user can take a folder full of papers, scan them one by one, and ask Lumyeye: “Tell me what you see?”

Lumyeye might respond: “I see an advertising flyer for a carpenter.” At that point, you can either move on to another document or request a full reading of that one.

4 – Character Recognition (OCR)

OCR is a technical term that stands behind every intelligent text reading.

The app uses OCR (Optical Character Recognition) to read text from images. OCR is essential for administrative documents, receipts, restaurant menus, and more, because it makes it possible to organize and structure blocks of text.

​

The app can extract and organize key information such as:

  • Amount to pay

  • Product name

  • Bank balance

  • Essential details from a letter

It can also distinguish between an article and an advertisement on a two-page spread and adapt the summary according to the type of document.

Similarly, when taking a photo, if you capture only part of a text that doesn’t belong to a complete block, OCR will detect it and avoid reading just fragments of words.

5 – Intelligent Voice Search

The app also allows users to perform voice-activated internet searches:

“What is Humira®, AbbVie used for?”
“How do I get to Colombus station from here?”
“Who is the president of Canada?”

With the help of a specialized AI, answers are spoken out loud, clear, and interactive: the user can ask follow-up questions without needing to start over.

Lumyeye keeps the conversation history active while the exchange is ongoing, so the user can ask several related questions on the same topic.

“Who was Napoleon?” → The voice app replies: Napoleon was…
“What were his major battle dates?” → Lumyeye continues on the subject.

However, once the conversation ends, everything is erased. Lumyeye does not store any of your interactions—zero!

6 – Independence and Accessibility: 20 Essential Things a Mobile Voice App Like Lumyeye Can Do

A voice app for the blind improves daily independence by turning visual information into audio. Here are 20 essential ways it can support everyday life:

  • Read a document aloud
    Take a photo of a letter or a bill, and the app reads it clearly without scanning or any manual steps. See a demo here.

  • Recognize a bill or coin
    Show your money and the app instantly tells you the value (€5, €2, €0.50…), even from a wallet. See a demo here.

  • Identify clothing in a closet
    Point to a shirt or pair of pants, and the assistant describes the color, type, and sometimes even the visible brand. See a demo here.

  • Read a restaurant menu
    Browse the menu independently—dishes, prices, specials—all read aloud so you can make your choice with confidence. See a demo here.

  • Recognize a product on a shelf
    While shopping, find out what’s inside a box, can, or package—without outside help.

  • Understand an administrative document
    From a contract to a government form, take a photo and the app reads every line clearly.

  • Locate restrooms in a public place
