Abstract The purpose of this paper is to present a multichannel ultrasonic range finder which was designed for the navigation system for blind people. A substantial number of consultations with blind people in the Blind People Centre in Krakow have shown that the navigation and obstacle detection with a help of a white stick only, is not sufficient enough to assure a high safety level. Electronic aids which are being designed for blind people should be mobile, comfortable and low-powered. That is why the MOBIAN© (a mobile safety system for the blind) project is being carried out by the authors to create a highly reliable safety navigation system for blind people. It could not only improve blind people quality of life but also their safety, especially when they are walking in unknown areas. As a part of this project, the multichannel ultrasonic range finder was designed, produced and tested. The tests have proven the device is capable of detecting objects from different directions in a range over 4 m. The device interface is easy to manage and can be controlled by almost any microcontroller or FPGA chip. The designed range finder is to be implemented in the electronic assistant project for blind people. Other systems, including the industrial ones, for instance, mobile robots or gates that count people entries, could benefit from this multichannel range finder. Usually, some low-cost ultrasonic range finders use two transducers for each channel (a transmitter and a receiver). The designed device employs only one transducer per channel which minimizes the end-device size and cost and at the same time provides with the main functionality. Novelty of this device is its multichannel design and the emplacement of the ultrasonic transducers, which can be used due to the application of the multichannel analog multiplexer. Thus, it is possible to detect obstacles, even the inclined ones, with higher reliability and increase the safety of blind people while walking. Also, this design and the transducers’ placement allow to detect obstacles much quicker, when the blind user suddenly turns.

<p class="0abstract">The issue of lacking reference books in braille in most public building is crucial, especially public places like libraries, museum and others. The visual impairment or blind people is not getting the information like we normal vision do. Therefore, a multi languages reading device for visually impaired is built and designed to overcome the limitation of reference books in public places. Some research regarding current product available is done to develop a better reading device. This reading device is an improvement from previous project which only focuses on single language which is not suitable for public places. This reading device will take a picture of the book using 5MP Pi camera, Google Vision API will extract the text, and Google Translation API will detect the language and translated to desired language based on push buttons input by user. Google Text-to-Speech will convert the text to speech and the device will read out aloud in through audio output like speaker or headphones.   A few testings have been made to test the functionality and accuracy of the reading device. The testings are functionality, performance test and usability test. The reading device passed most of the testing and get a score of 91.7/100 which is an excellent (A) rating<strong>.</strong></p>

Nowadays, blind or impaired people are facing a lot of problems in their daily life since it is not easy for them to move, which is very dangerous. There are about 37 million visually impaired people across the globe according to the World Health Organization. People with these problems mostly depend on others, for example, a friend, or their trained dog while movıng outside. Thus, we were motivated to develop a smart stick to solve this problem. The smart stick, integrated with an ultrasonic sensor, buzzer and vibrator, can detect obstacles in the path of the blind people. The buzzer and vibration motor are activated when any obstacle is detected to alert the blind person. This work proposes a low-cost ultrasonic smart blind stick for blind people so that they can move from one place to another in an easy, safe and independent manner. The system was designed and programmed using C language. Keywords: Arduino Uno, Arduino IDE, ultrasonic sensor, buzzer, motor.

Sense Of Touch

Deaf and blind people find very difficult to communicate to other people. The latest technological development helps the people having disabilities particularly deaf and blind people to communicate to other people. These people can able to communicate with the help of their sense of touch. So the advance sensors integrating with the recent technology assists the people with disability for communicating with the other people. In this paper Glove based sensors combined with the Artificial Intelligence is demonstrated so that the deaf and blind people can communicate to other people in a big conference or any public places. It is also proved that the device developed is a low cost wearable device which is affordable to such a weaker section of people having disabilities. Raspberry-pi and mobile device are cantered around the sensors to process and communicate. With the help of the device demonstrated in this paper people with disabilities specially deaf and blind can involve freely in day to day regular activities.

Twenty-nine visually handicapped subjects participated in a research project in which a daily newspaper was transmitted into their homes and read to them with the help of speech synthesis. With the use of computer and telecommunication techniques, almost the entire newspaper was transmitted; this is an important change in providing news to blind people. Questions of interest in this study included the subjects’ reactions to the reading device and their use of the different reading facilities offered. Reactions were, in general, very favorable. The project demonstrated the importance to the subjects of receiving a newspaper at the same time sighted people received theirs and the chance to choose what to read easily. The intelligibility of the synthetic speech was considered high. Although the subjects read a lot, they mainly used few of the available commands. In areas in which it was possible to compare their reading habits with those of sighted persons, striking similarities were found.
