Lazzus. Geopositioning app for blind and visual impaired people

What is Lazzus?

Navigate the city and explore your surroundings independently

Lazzus is an assistant that accompanies blind and visually impaired people as they move around, creating an auditory field of vision.

It points out useful things around you, such as pedestrian crossings, street intersections, stairs and businesses, helping you to get around safely and explore your surroundings more intuitively.

It also guides you to places you never thought you’d be able to go without someone’s help.

What sets Lazzus apart?

Lazzus uses two complementary and extremely powerful data sources: Google Places (the most up-to-date source in the market) and Open Street Map, which means the information it provides is more accurate and you can discover more places of interest.

It searches a 100-metre radius, which helps you explore because it only highlights information on things that are near you at any given time.

Lazzus has been tested and approved by the CIDAT, a leading centre for accessibility and support products for the blind, which is run by ONCE, Spain’s association for blind people.

It received the 2015 Vodafone Foundation "Mobile for Good" Award for Innovation in Communication."

It was also recognised with the 2015 Google Startup Award for mobile innovation.

What Lazzus users have to say...

"I use it on the bus. It’s great how it tells me what street number we’re at."
Gloria Montota (Álava)

"An excellent app! It’s amazing how many places it can recognise. I absolutely recommend it, it is very useful and easy to use."
Miguel Fernández (Madrid)

"A really good app that lets you move around more independently."
Concha de la Fuente (Algeciras)

"This is an excellent app and it is very good for those of us that don’t have any residual vision. I am extremely grateful to the creators [...] in the next update they could add a search button so we can put in an address and go from one place to the other."
Jesús Manuel Muñoz Guisado (Extremadura)

How does it work?

How do you want to explore?

You decide:

Beam mode tells you what there is in whichever direction you are pointing your mobile.

360º mode highlights everything in your immediate surroundings in every direction.

Transport mode is automatically activated when you travel by bus or car and tells you which streets you are passing, so you never get disorientated.
