Project Summary

Visually impaired people find difficulties detecting obstacles in front of them, during walking in the street, which makes it dangerous. The smart stick is a solution to enable them to identify the world around. In this proposal we propose a solution, represented in a smart stick with infrared sensor to detect stair-cases and pair of ultrasonic sensor and laser distance sensor to detect any other obstacles in front of the user, within a range of one to four meters. Moreover, another sensor is placed at the bottom of the stick for detecting the moisture or surface of road. Buzzer warning messages and the vibration motor are activated when any obstacle is detected. This proposed system uses the microcontroller embedded system, vibration motor and Sensors. The stick is capable of detecting all obstacles in the range 1 to 4 meter during walking and gives a suitable respect message empowering blind to move twice his normal speed because she/he feels safe. The smart stick is of fast response, low power consumption, light weight.

Project Objectives

We have many reason to design smart stick for blind people: firstly, to make the blind people to feel free, it isn’t surrounded by wires as in belt. Secondly, it is easy to use because it is familiar and smart. Thirdly, smart stick is able to detect obstacles that exist on the ground (this is not available in glasses), which normally blind people faced obstacles such as stairs and sidewalks during walk.

Project Implementation Method

To detect and record information about the obstacles presence in a road, active or passive sensors can be used. In case of a passive sensor, the sensor just receives a signal. It detects the reflected, emitted or transmitted electro-magnetic radiation provided by natural energy sources. In case of using an active sensor, the sensor emits a signal and receives a distorted version of the reflected signal. It detects reflected responses from objects irradiated with artificially generated energy sources. These kind of active sensors are capable of sensing and detecting far and near obstacles. In addition, it determines an accurate measurement of the distance between the blind and the obstacle. Overall, in the obstacle detection domain.

Benefits of the Project

The Smart Stick acts as a basic platform for the coming generation of more aiding devices to help the visually impaired to be more safe. This system offers a reliable, portable, lowpower consumption and robust solution for navigation with obvious short response time. Though the system is hard-wired with sensors and other components, it's light in weight. Further aspects of this system can be improved via wireless connectivity between the system components, thus, increasing the range of the ultrasonic sensor and implementing a technology for determining the speed of approaching obstacles. While developing such an empowering solution, visually impaired and blind people in all countries were on top of our priorities.

Technical Details of Final Deliverable

Fig. 1 and Fig. 2, are some technical assumptions (diagrams) of our project which is not final as we will work on it, and our main objective is how to enhance its functionality and reliability. we are also work how to increase its obstacle detection ability through increasing of its sensors quantity and other ways, IN.SHAH.ALLAH our this efforts will increase its efficiency.
