Lazarus, a mobile application for Android that helps blind or visually impaired people to move around the city and perform simple tasks of daily life without the face-to-face help of a caregiver, family member or friend using only basic tools such as geolocation, voice recognition or the camera.
Lazarus has two types of users:
Blind users: people who need help in situations of confusion (like getting lost in a public space) or emergency (read a warning text, for example).
Helper users: volunteers willing to “lend” their eyes to those who can not see. Its function is to answer the questions of blind people by transcribing texts or describing images
What can the app do for blind people?
Lazarus has 5 basic options that can be used manually or with simple voice instructions.
1. Location: A lost user can instantly know where he is thanks to simplified maps, specially designed for people with visual disabilities, and GPS.
2. Close to me: This option indicates relevant spaces that are around the user in an area of 500 meters as: pharmacies, banks, post offices, supermarkets or coffee shops.
3. Look for me: This option allows the user to ask other people what is happening around him eg in situations of confusion or danger (knowing if a food is in a good condition or some pills without a box are the ones he have to take). The user only has to take a photograph and thanks to the help of volunteer users, will solve his doubts.
4. Read text: Lazarus automatically translates written texts into voice messages through an OCR process.
5. Describe object: Lazarus can recognize objects from the real-world in order to help you with your daily issues.
