It's a innovative stick to help the visually disabled people. It helps the blind people to navigate their way easily without having to touch the obstacle.It detects the solid as well as liquid/water obstacle .It also helps them to know their location through GPS.

We are in the age of science and technology which have made our daily life more easier and comfortable.We have got smartphones, smart watches, smart home appliances and this trend of smart world is ever growing.So using such smart technology we aim to help visually impaired people for nagivation.Blindness­ is not just a medical condition but possesses the larger dimensions of social exclusion, stigma and neglect.Blind people are often taken by surprise by over-hanging branches, protruding air-conditioners and parked vehicles while navigating through unfamiliar terrain.According to the World Health Organisation, there are 285 million people estimated to be visually impaired worldwide and 90% of them live in developing countries.The main objective is to offer blind and visually impaired communities a smart device that gives them independent personal mobility outside the home.Smart blind stick is an innovative high-tech stick that will help visually impaired people to detect obstacles near them and nagivate their way.This technology is set to make lives better for the visually impaired human kind. The smart blind stick is integrated with ultrasonic sensor along with light and water sensing.This smart technology sends out ultrasound waves via a device attached to a standard white stick & it detects them on their return, and uses vibrations to inform users of any obstacles in their way.

This technology is set to make lives better for the visually impaired human kind. The smart blind stick is integrated with ultrasonic sensor along with light and water sensing. Ultrasonic sensors detects the obstacles ahead using ultrasonic waves. The sensor senses the obstacle and passes this data to microcontroller. The microcontroller then processes the data and calculates the distance. If the obstacle is far away then the circuit does nothing. If the obstacle is nearby then microcontroller send a signal to sound a buzzer. We have two modes for the distance. They are indoor mode and outdoor mode. Indoor mode, Objects that are 1.8meteres away are detected. Outdoor mode, objects that are 3meters away are detected.  If the sensor detects the water then the stick vibrates through the vibration motor which is linked with microcontroller. The buzzer and vibration motor is kept to alert the blind. It also detects the  brightness or darkness of light  in the room through light detector. we use RF based remote to help the blind find the stick if they forget where they kept it. Pressing on a remote button sounds a buzzer on the stick which alerts the more advance feature is the location can know his/her location through the mic assembled in the stick. For this feature we use GPS to track the one's location. The microcontroller is coded with GPS module to Know the location. Thus this system allows for 

  • obstacle and water detection
  • light detection
  • find a stick if it is misplaced by visually disabled people
  • location knowing


Target Location :

mostly urban areas

Target Audience :

visually impaired people

Scope :

Benefit :

According to recent National Population Senses 2011 the population of Blind is 96,000.Blindness is not only a health problem but also a social and economic problem.It helps them to grow both socially and economically.It makes travelling easier.It helps them during monsoon from the damaged water filled roads.
