Abstract - This paper represents a system which explores
the reality of color in relation to sound and dedicated firstly to blind people, the challenges they live with, their psychology and their emotions. It’s an exploration of the infinite range of colors that they have either never been able to see or that they have lost the possibility to see. The system developed is based on the concept of synesthesia: a ‘liaison’ between color and sound, color that becomes sound. This paper synthesizes a wider range of study regarding people with diverse psychological and movement conditions. Finally we conclude with a portable prototype device that has been validated and patented. It is capable of detecting color and transforming it into sound: a color sensor identifies colors and transforms this data into musical notes. The prototype is totally adaptable to the requirements of the end user meaning that the user can choose the best combination between color and sound in order to improve their communication with the environment. We are now developing a mathematical theoretical background in order to formalize the correspondence between color and musical space.

1. INTRODUCTION:-
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. Color represents one of the most important and conditioning aspects of the reality that surrounds us. It has the great capability of moving us, impressing us and of creating meanings and symbolic values which, consequently, play a part in the culture and traditions of each one of us. In general color isn’t perceived uniquely through our eyes but © 2017, IRJET

also thanks to other aspects of a cultural type, through our conscience and subconscious. Aspects like primordial images, symbolism, cultural influences and traditions as well as personal experiences all form part of our singular and personal way of perceiving color. Color is associated to feelings and basic life concepts such as romance, tranquility, hate, happiness, sadness, etc. as concluded by the many studies that have been made on the subject: the symbolism which belongs to color walks hand in hand with common imagination .Color, associated with either hearing or touch, represents one of the most common combinations in this field. Color is connected to other senses besides sight. Blind people create concepts based on their personal experience and according to their point of view and imagination. They associate descriptive words and every day conversation to feelings, things they read, tactile experiences, hearing, taste and smell. Just because a blind person cannot ‘see’ color, this does not take away from the fact that they can interpret it in their own personal way. It is a device capable of detecting colors and transforming them in to musical notes or melodies inspired by the concept of synaesthesia which plays a fundamental role in the whole of the project. It represents an innovative study from a theoretical and technological point of view and it includes all the important ingredients in a proposal of social credibility as it encloses a wide range of problematic situations and disabilities. It counts on an important technological component, with the programming of the software of the device and the modeling of an original color/sound concept.
2. LITERATURE SURVEY:Assistive systems are being developed for different kinds of visually impaired people to improve the life quality and safety of such people including indoor navigation and way finding, display reading, banknote recognition, rehabilitation, and many more. Xuedong Yang developed a system for blind people to select clothes based on cloth pattern and colors in a cloth shop independently. This is a camera based system that can handle clothes with complex pattern and recognize clothes into four categories (plaid, stripped, pattern less, and irregular) and identify 11 colors : red, orange, yellow, green, cyan, blue, purple, pink, black, grey and white. FAIZ .M. HASANUZZAMAN proposed a system to automatically recognize banknote of any currency to assist visually impaired people. This is also a camera based ISO 9001:2008 Certified Journal
