Presentation Day

Design and do the poster for Presentation Day

This month I design and do the poster to my project for presentation day. This poster is combination all about objective, application, methodology, diagram, description, result, benefit and conclusion.

Demostration for this project created by myself

Result and Conclusion for project

This is flow of operation.

 This is a flow of basic operation for this project. Development of smart blind cane is using ping ultrasonic sensor and voice module. PIC 16F877A will programmable the function that a cane want operate. The ultrasonic is function to send the transmitted pulse and feedback the receiver pulse to determine the distance in front. The voice module is function to feeds warning back, in the forms of voice messages and buzzer, to users.

            Firstly, if there obstacle and barrier in front, and the ultrasonic sensor will send the signal to circuit microcontroller. The microcontroller read the language of c programming that flow how the PIC function to ultrasonic sensor and voice module. The cane detected by ultrasonic sensor to determine the distance of barrier in front. After that, when signal microcontroller will active a transistor drive relay circuit for switching ON the relay. This project is using two of transistor drive relay. Then, the signal is send to the voice module and feed the warning to user. The circuit will cause the relay to another transistor drive relay circuit unit switching ON to stop or cutoff the voice warning. The buzzer is use direct incoming supply between switching ON with PIC. When the distance of barrier detected, the buzzer will produced a sound. Finally, the user can communicate with users the barrier detection in front by voice alert and buzzer.

This is my finally pic for my project.

Conclusion

The main purpose of this study is to produce a prototype that can detect objects or obstacles in front of users and feeds warning back, in the forms of voice messages and vibration, to users. Combination of ultrasonic sensors and a microcontroller function for detection and distance stick and obstacles in front of. This project is to people with disabilities that are blind to facilitate the movement and increase safety.

The smart blind cane is successfully designed consistent with all the objectives achieved. The first objective is achieved by applied the programmable distance and barrier detection system ultrasonic sensor. Develop a product or hardware that can determine distance and detect barriers in front barriers. The second objective is achieved by complete the design to investigate the design smart blind cane using ultrasonic sensor, PIC, voice module and buzzer. The third objective is achieved by design to provide data on a navigation system based use ultrasonic sensor for barrier detection and studies that to help visual-impaired to move in front very well and safety navigate.

One of the most important difficulties faced by the visually challenged persons is constraints in independent mobility and navigation. They primarily use the white cane as a mobility aid allowing them to detect close by obstacles on the ground. The detection of objects above knee height is almost impossible and is a major hindrance for them.  Developments in embedded systems have opened up a vast area of research and development for affordable and portable assistive devices for the physically challenged.

This project aimed at the design and implementation of a detachable unit which acts to augment the functionality of the existing white cane, to allow knee-above obstacle detection. This unit consists of an ultrasonic ranger and a vibrator controlled by a microcontroller to offer an increased detection range of three meters. The distance information is conveyed to the user through non-interfering multi-frequency vibratory stimuli, the frequency of vibration indicating the proximity of obstacles. This unit is also capable of detecting fast moving obstacles.

A lot of effort has been put in the electromechanical design of this unit conveying the vibrations effectively and ensuring that it is easily attachable on the existing white canes without sighted assistance. A crucial design optimization goal was cost the unit has been developed as a low cost device which is affordable by the poor in developing countries.

Besides that, we get the benefit for this project. This project is an automatic system that uses ultrasonic sensors to be detecting the obstacles in front by a micro controller.  Adding security features for the disabled (blind). Facilitate the people with disabilities to move freely.  This project will operate to help all of the blind people in the world to make them easier to walk everywhere they want. This project was done to help the blind to move in front very well.

This smart blind cane by using technology system is successfully achieving the objective. That can detect objects or obstacles in front of users and feeds warning back, in the forms of voice messages and buzzer, to users. This project is to people with disabilities that are blind to facilitate the movement and increase safety.
