Blind since old age have been using walking stick and also walking dogs for their mobility purposes. many different types of electronic travel aid are available: These use either ultrasound or laser beam. One of such devices is the laser cane that is similar to a long cane with built-in laser ranging facilities.Most use ultrasound for functioning.These use the reflectance property of the high frequency ultrasound and are available in different
models like:
1.Sonic torch
a hand held device and operates on the principle of transmittin ....etc

Abstract

Mobility for the blind is always a great problem.Just like a sighted, blind also needs to travel around inside
a closed premises like house, factory, office, school etc. They may also like to go for shopping, visiting friends and other places of their interest. Presently available electronic travelling aids like sonic path finder, sonic torch etc. are not suitable for using inside a closed premises such as school,factory, office etc. In this paper an electronically guided walking stick tha ....etc

Hello smart engineering people,

I'm a mature student doing my last semester in college.
I need to present the following project: a blind-stick that vibrates and buzzes when it is close to an obstacle. I'm using ULTRASONIC sensor.

Would anyone be kind and give me any hints? I don't know even what the block diagram should look like.

Please help.

Thank you.

Kind regards,

Blind stick is an innovative stick designed for visually disabled people for improved navigation. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. The blind stick is integrated with ultrasonic sensor along with light and water sensing. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. On sensing obstacles the sensor passes this data to the microcontroller. The microcontroller then processes this data and calculates i ....etc
