Obstacle sensing cap for Blinds
Project Area of Specialization Mechatronics EngineeringProject SummaryThe Multidirectional obstacle sensing cap is made for the blinds or low vision person. This device provides a sense of sight to the person using it but intimating them about the obstruction which they cannot detect through their blind stick, most commonly the head level obstacles like, banners, branches of trees, low height door and many other like that. The device is made by using a microcontroller (Arduino) which allows users a simple pathway to creating interactive objects that can take input from switches and sensors, and control physical outputs. An ultrasonic sensor is also used to drive input to the microcontroller and generate desired output when needed. A buzzer is attached as well to the output of the sensor.
Project ObjectivesThe objective is to reduce the head level injuries which a blind person faced in their daily life routine.
Head level accidents are most common problem a blind person faces in their entire life, and many more some can come through from the sides as well, while turning to side the blind person can have injury if there is some obstacle aside him. This device allows the person to detect the head level obstacles in front of him and aside the person. As research of The World Health Organization (WHO) reported that there are 285 million visually impaired people worldwide. Among these individuals, there are 39 million who are totally blind. There have been several systems designed to support visually impaired people and to improve the quality of their lives. Unfortunately, most of these systems are limited in their capabilities. Our aim is to address and present most of the issues of these systems to pave the way for visually impaired people & design device that ensure safety and independent mobility to visually impaired people.
Project Implementation Method| Features | Description |
| Analysis Type | The system needs to provide fast processing for the exchanged information between user and the sensors. |
| Coverage | The system needs to provide services indoor & outdoor to improve the quality of visual impaired people's life. |
| Time | The system should perform evenly in Day time and nighttime. |
| Range | It is the distance between the user and the obstacle to be detected by the system. Ideal minimum range is 0.5m whereas the maximum should be more than 5m. |
| Object Type | The system should not avoid the sudden appearance object, means system should detect static as well as dynamic object both. |

Technical Details of Final DeliverableThe technology which is being in this device is Arduino/Genuino Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. You can tinker with your UNO without worrying too much about doing something wrong, worst-case scenario you can replace the chip for a few dollars and start over again.
"Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past, or outdated boards see the Arduino index of boards
