For visually impaired people it is not easy to find out who and what is around them. A walking stick is the only support which can boost their morale and help them escape all the hurdles.
According to the WHO’s report, 285 million people are estimated to be visually impaired worldwide in which 39 million are blind and 246 million have low vision. 82 per cent people living with blindness are aged 50 and above.
India has one of the largest blind population. Taking it as responsibility a group of students of Maharaja Agrasen Institute of Technology have developed an automated assistive aid (White Guide), which requires very less adaptation to a new walking style. White Guide is an electronic device that can be attached to the conventional white cane. It detects the presence of obstacles using ultrasonic waves that are conveyed through intuitive audio patterns. White Guide has two key features, one is obstacle detection another is SOS and real time tracking of the person by the support.
The device has a synced Android application linked to it. The app registers all the data entered into the user’s profile such as contact numbers of up to 3 people and their e-mail id. The device contains an emergency button. On pressing this button, it gives an offline message to the contacts of the user mentioning the current location of the person, which can be tracked through the white Guide app or Google map.
