This system incorporates an acceleration sensor in the baton, transmits data to a player via radio signals, and acts as a haptic interface by generating vibrations. In this paper, we experimentally evaluate responses to the stimulus of the visual and the tactile senses in order to verify that a haptic interface can substitute for vision in scenarios that involve real-time tasks, such as music lessons. In the first experiment, we verify that clue motions are important for both the visual and a tactile senses. Next, we test the new method of communicating strength. Thismethod uses not vibration strength but oscillating time for vibrations of the haptic device. The results of the experiment confirm that the technique is effective. </span>

Locating objects in an image is a very useful task for robotic navigation and visually impaired persons. The ultimate goal of my work is to position the recognized objects in the image. Objects are detected using Adaboost techniques and also recognized from the real-time images. Objects are detected using AdaBoost classifier. SIFT features are extracted from the objects found in the image and classified using Support Vector Machine, and the position of an objects are estimated. We proposed IOLE algorithm to estimate the location of object in an image

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.

Environmental classification is very useful for visually impaired persons and Robotic applications. The main objective of this work is to detect and recognize the objects present in a scene and identify the environment based on the occurrence probability of the objects in the scene. Objects from the real-time images are detected and recognized by means of RetinaNet. Occurrence probabilities of the recognized objects are used to identify the environment.

Studies have shown inadequate reading materials for the visually impaired in Nigeria. Information technology has greatly advanced the provision of information to the visually impaired in other industrialized climes. This study investigated the extent of application of information technology to the transcription of reading materials for the visually impaired in Nigeria. The study adopted survey research design of the ex-post facto to select 470 personnel as respondents. A questionnaire titled Information Technology Use Scale (α=0.74), and Interview Schedule (α=0.75), were used. Data were analyzed using descriptive statistics and Pearson Product Moment Correlation. The findings indicate that information technology in transcription was low and a significant positive relationship between application of information technology and transcription of information materials (r=0.62: p<0.05). The study recommended among others that Multi-National Corporations should be sensitized to extend their Corporate Social Responsibility (CSR) activities to help in procuring modern information technology devices and software to enhance transcription.
