Visually impaired persons have difficulty in business that dealing with banknote. This paper proposed a Malaysian banknotes detection system using image processing technology and fuzzy logic algorithm for the visually impaired. The Malaysian banknote reader will first capture the inserted banknote image, sending it to the cloud server for image processing via Wi-Fi medium. The cloud server is established to receive the banknote image sending from the banknote reader, processing them using perceptual hashing based image searching and fuzzy logic algorithm, then return the detected banknote’s value results back to the banknote reader. The banknote reader will display the results in terms of voice message played on the mini speaker attached on it, to allow visually impaired persons knowing the banknote’s value. This hardware mechanism reduces the size and costs for the banknote reader carried by the visually impaired persons. Experimental results showed that this Malaysian banknotes detection system reached an accuracy beyond 95% by running test on 600 different worn, torn and new Malaysian banknotes. After the banknote image being taken by the banknote reader’s camera, the system able to detect the banknote value in about 480 mili-seconds to 560 mili-seconds for a single sided banknote recognition. The banknotes detection speed was also comparable with human observers reading banknotes, with the response of 1.0908 second per banknote slight difference reading time. The IoT and image processing concepts were successfully blended and it provides an alternative to aid the visually impaired person their daily business transaction activities in a better way.

In This Paper we present a real time domain obstacle detection system for the visually impaired persons to improve their mobility in daily life with the help of obstacle detection sensor installed in their walking stick .System is having a lower cost so it is easily purchasable so it can have a major significance in life of visually impaired persons. This Paper proposes a system to detect any object attached to the floor regardless to their height [1]. Obstacle on the floor in the front of user can be reliably detected in real time using the proposed system implemented by the IR sensor installed on the walk stick of the visually impaired person. Project also contains a navigation system for visually impaired persons to make the life of such persons easier up to some extent. This project is suited for the area where the possibility of blind person is high (like blind school, college)[6]. For transport facility of blind we have first decided the common bus roots of blind then we have placed RF tag to all those buses with unique code. At the second side we have placed RF reader, microcontroller and voice processor. The RF reader receive unique code, microcontroller process this code with defined code, if match found, voice processor get activated and starts speaking bus name, initial destination and final destination. The obstacle detection is also included in the project with voice. The system aims at increasing the mobility of visually impaired people by offering new sensing abilities.

Many visually impaired individuals are found to be too passive or too aggressive in their social interactions. Lack of assertive behavior is related to the concept of learned helplessness. Components of assertive behavior are described with suggestions for enabling the visually impaired person to develop these skills. The underlying concepts of assertion training are explained along with specific techniques to be utilized in the school or rehabilitative setting. With a structured intervention resulting in improved assertiveness skills, blind or partially sighted individuals can increase their effectiveness in communicating with others and can feel more in control of their lives.

This chapter shows how elements of gamification, i.e. game thinking and game mechanics, can be integrated into a collaborative navigation system for visually impaired persons in order encourage them to travel independently and thus improve their quality of life and self-confidence. The system supports independent navigation in unknown places by mediating help from another visually impaired person, who is familiar with the particular place. Our system utilizes a thermal user interface to introduce an additional communication channel and thus to increase the usability of the system. The system has been successfully enhanced by game elements and illustrates the potential of introducing game elements into these systems.

Walking Stick

Visual impairment burdens the people heavily in today’s fast-moving culture. Although there are several measures for this impairment, many people skip such chances in fear of their economic condition. In view of helping those people, a sophisticated stick is designed using sensors like ultrasonic sensor, IR sensor and Arduino ICs. Electronically designed walking stick helps to trace the locations using GPS module and to avoid collisions through detection of objects at a certain range of distance from the person in all directions. Sensor placed beneath the bottom of the stick enables the identification of pits/hindrances on the ground. The visually impaired person will be alerted with a voice message generated using the voice recorder which records the response of all the sensors operating in different tracks. In this paper, GSM and sensors together have initiated the role of smart walking stick in the life of several human kinds.

Objective: to analyze mental health in the face of visual impairment, identifying the stages of psychological distress in the encounter with the not seeing. Method: This is an exploratory study with a qualitative approach. Fifteen adults with visual impairment attended at a specialized ophthalmology ambulatory in a university hospital in the city of Natal, Rio Grande do Norte, Brazil were studied, from June to August 2015, through a semistructured interview. The speeches were analyzed based on the theory of mourning. Results: the results showed that the mental health of the visually impaired person is structured through a normative apparatus constituted of individual and social attributes dynamically constructed. These attributes are related to the constitution of stages of mourning, characterized by shock, denial, bargaining, depression, and acceptance. The mental health of the visually impaired person contemplates the phases of normal mourning, established before the condition of visual loss, as structuring mode in a process of personal reconstruction, reflected in the ways of walking the life, proper from each one. Conclusion: With this study, it was possible to understand the ways of constitution and reconstitution of people in dealing with a new condition, the one of visual impairment, providing caregivers, family, and society with an ethical spirit and solidarity, more compliant and humane in the to deal with people with disabilities.

Visual impairments often pose serious restrictions on a visually impaired person and there is a considerable number of persons, especially among aging population, which depend on assistive technology to sustain their quality of life. Development and testing of assistive technology for visually impaired requires gathering information and conducting studies on both healthy and visually impaired individuals in a controlled environment. We propose test setup for visually impaired persons by creating RFID based assistive environment – Visual Impairment Friendly RFID Room. The test setup can be used to evaluate RFID object localization and its use by visually impaired persons. To certain extent every impairment has individual characteristics as different individuals may better respond to different subsets of visual information. We use virtual reality prototype to both simulate visual impairment and map full visual information to the subset that visually impaired person can perceive. Time-domain color mapping real-time image processing is used to evaluate the virtual reality prototype targeting color vision deficiency.

Image processing has become one of the most important branches of computer science, especially after entering into several areas of life such as medicine, engineering and various sciences. In our current research, we have developed a system of image recognition based on image characteristics and some content information using the most important artificial intelligence algorithms, a fuzzy logic algorithm, to obtain complete image information using small values ranging from 0 to 1. The program was executed on a set of standard database called the WANG database. It holds the contents of 1000 images from the Corel stock photo database, in JPEG format. The system was evaluated using the recall method. This method calculates the proportion of correct results identified by the system as correct results with correct result identified by the classic system.
