Arduino Based Color Detection for Visual Impaired

2019

Blindness is the condition of poor visual perception, estimation from World Health Organization state that 285 million people are visually impaired worldwide, 39 million are blind and 246 million have low vision. A Blind person with proper training can function like any person with perfect vision, but there are the small things that can improve the quality of a blind person life, like color detection which is the focus of this project. Being able to detect color can help in many ways, like identifying colors of clothes or even identifying uniquely colored objects (e.g. paper money) and appreciating art. The project will help overcome challenges that visually impaired people face in daily basis, by creating a way to detect colors and providing unique biofeedback for each color. The proposed embedded system imbibes Arduino microcontroller which reads the RGB data from the color sensor TCS 230 which when processed further classify the color based on the lookup table programmed within the controller. The color so identified is displayed along with the RGB combination and also audio feedback of the color identified is given using DF player interfaced with Arduino. During the testing the embedded system the success rate of identification of colors was found to be 93%.

A colour recognition device for the visually disabled people

Indonesian Journal of Electrical Engineering and Computer Science

Visually disabled people rely on the sense of touch and sense of hearing to help them recognise anything in their everyday life. Colours, however, is also important in giving information about things such as the colour of cash note (blue, green, red, orange and purple), the colour of spices (yellow turmeric, red chilli, green chilli) and colour of cloth. Without a sense of visual, they are not able to recognise colour and perceive the beauty of colour. This study was conducted to develop a colour recognizer for visually ‎disabled people‎. Colour recogniser used the colour sensor to sense the colour, microcontroller to recognise the colour and notify the user using a speech generator and speaker. The device is powered by dry cell batteries and designed to be user-friendly, practical and portable. The testing is done to show that this device was able to sense and differentiate 12 primary colours in the RGB colour wheel and validated the accuracy of this devices.

Assist System for Visually Impaired People to Recognize Pure Colours

Visually impaired individuals are growing segment in this era. Developing tools for visually impaired people is not a recently emerged problem. But developing computer aided tools are still developing area for visually impaired people. Assist system for visually impaired people refers to system that is able to assist or guide people with vision loss, ranging from partially sighted to totally blind, by means of sounds of commands. Our developed system involves detecting pure colours for visual impaired people to identify colour of clothes and medicine based on the pure colour packets. This collection of insights is laid out in audio format to assist with identifying pure colour of clothes. This system can use instead of traditional way of identifying above mentioned matters. Traditional ways are, they use white cane for mobility and get assist from second person. To identify pure colour of clothes, they get help from another party. To overcome the white cane mobility challenge, this proposed system "Assist system for visually impaired people" could be a solution for constraints in independent mobility, identifying colours in efficient manner. The system is made to identify colours using TCS230 Colour Sensor and Ardunio Board. Ultimate goal of this system is to uplift the life style of visually impaired people by making them more independent and aware of their surroundings by hearing sound. The system has been tested in real time by both blindfolded and blind people at different indoor and outdoor locations, demonstrating that it operates adequately.

Object Identification and Colour Recognition for Human Blind

2004

Navigation Assistance for Visually Impaired (NAVI) is a vision substitute system designed to assist blind people for autonomous navigation. NAVI working concept is based on 'image to sound' conversion. The vision sensor, which is mounted on a sunglass, captures the image infront of blind user. NAVI processing unit processes the captured image and enhances the significant vision data by employing a set of image processing procedures. The processed information is then presented as a structured form of acoustic signal and it is conveyed to the blind user using a set of earphones. This paper proposes a new object identification and colour recognition module for NAVI system. Image processing techniques are proposed to identify objects in the captured image and then the processed image is transformed into stereo sound patterns. Colour information from the interested object is evaluated to determine the colour of the object. The colour output is informed to the blind user through 'verbal voice'.
