Portable Camera Based Assistive Text Reading from Hand Held Objects for Blind Person

ABSTRACT: We propose a camera-based assistive text reading framework to help blind persons to read text labels from hand-held objects in their day to day lives Self-Dependency of blind people is very important in their day-to-day lives. This paper presents a cost effective prototype system to help blind persons to shop independently. As we know printed text is everywhere like product names, instructions on medicine bottles, restaurant menus, signed boards etc. To read these text blind and visually impaired people need some help? This paper presents a camera-based assistive product label reader for blind persons to read information of the products. It is hard to detect text due to the variations of text font, sizes, color text, clutter background and different orientation. In this paper Camera is used to captured the image of the product .Then captured image is processed internally using different algorithms such as text localization and text recognition algorithm to extract text the label from image by using MATLAB .The extracted text label is converted to audio output using text to speech converter and it is pronounced as audio to the blind person.

Portable Gadget Based Assistive and Label Reading For Blind Person: A Review

Portable Gadget Based Assistive and Label Reading For Blind Person: A Review

D. Dakopoulos et al [10] proposed a camera based technique to identify the hand-held objects. From cluster of background an object is identified. For that region of interest (ROI) are used. Novel text localization algorithm is used to get the gradient features of edge pixels using Adaboost model and region of interest (ROI) is found out. These texts are binarized and threshold value is obtained for that text character. Finally speech output is obtained from the binarized text character. This project also used for the blind person in their daily lives. Firstly, we have to shake the object to recognize the text. But, now it will automatically recognize the text character in the hand of blind person. It is also converting the text into binaries but optical character recognition (OCR) software is used here. Then finally speech output is obtained.

which is a Python program and should be copied to Raspberry Pi. The HTML file has a basic user interface with two buttons. When the button is pressed, a PHP program is executed that writes a string to the process.txt file based on the pressed button. The .txt file stores the last URL information for the button. C. Voice to text: The third process we provide for difficult hearing that others can not learn. In order to help them in accordance with the Parliamentary Act, we have used this auxiliary device for the deaf. This procedure recognizes the voice signal and assigns a minimum voltage threshold that begins to input the voice signal through the voice application AMR, and then retrieves and maintains the converted text on the LCD. First the Bluetooth connection must be setup between the AMR voice app and the HC-05 module by entering the default password 1234/0000. After the connection setup the person can be able to give the voice input, the AMR voice app converts the voice to the text format. The converted text string is send to the Raspberrypi module using Bluetooth. Upon receiving the text string it displayed on the LCD display.

An Improved Text detection based on Morphological Operations and Inpainting

ABSTRACT: Dictation using speech recognition input method for mailing devices for blind. This Application is used for Visually Challenged people to access mail efficiently. The main benefit of this system is that the use of keyboard is completely eliminated. The user will have to respond through voice and mouse click only. Thus reliance of visually. The users of this system would not need to have any basic information regarding keyboard shortcuts or where the keys are located. All functions are based on simple mouse click operations making it very easy for any type of user to use this system Impaired on other people for their activities related to mail can be reduced. This application proposes an android application, designed specifically for visually impaired people. This application provides a voice based mailing service where they could read and send mail on their own, without any guidance. The users have to use certain keywords which will perform certain actions for e.g. Read, Send, Compose Mail, Address Book etc. The VMAIL system can be used by a blind person to access mails easily and efficiently This makes internet a completely useless technology for the visually impaired and illiterate people. Even the systems that are available currently like the screen readers TTS and ASR do not provide full efficiency to the blind people so as to use the internet. As nearly 285 million people worldwide are estimated visually impaired it become necessary to make internet facilities for communication usable for them also. Therefore we have come up with this project in which we will be developing a voice based email system which will aid the visually impaired people who are naive to computer systems to use email facilities in a hassle free manner. The users of this system would not need to have any basic information regarding keyboard shortcuts or where the keys are located. All functions are based on simple mouse click operations making it very easy for any type of user to use this system.

Blind Assistant

Blind Assistant

Project researched by Chucai Yi Roberto W. Flores Ricardo Chincha YingLi Tian Is a camera-based system intended to help blind or visually impaired individuals discover their daily requirements. This suggested scheme will identify objects on a camera-based network and on corresponding-based recognition. Here data sets of daily necessities have been gathered, and Speed-Up Efficient Functions and Scale Invariant Feature Transform feature descriptors have been used to conduct object recognition. Multiple camera system is constructed by putting a camera at key places in the enclosed environment of a blind user's daily routines. The cameras supervise the situation around these set places and tell blind people of the places of their requested products. Matching-based image recognition is conducted throughout this phase to locate items. Then the program will submit the most comparable item, even if it matches the length, and advise the blind person to get near to its place. Later, the camera connected to the disabled person will conduct more identification to confirm the presence of the requested item.

Navigation Dialog of Blind People: Recovery from Getting Lost

Navigation Dialog of Blind People: Recovery from Getting Lost

When blind people travel independently, it may happen that they get lost. This happens when they can not find any useful navigation points. Use of existing GPS based navigation systems is of no use as the maps do not provide appropriate navigation points and the GPS localization is imprecise (tens of meters, where the lost blind person needs preci- sion at highest in meters). In such situation blind people typically use one of two following meth- ods to recover. First they can ask people in their surrounding for help. Second they can call friend or dedicated assistance center. The first method is currently more favorable for blind people, but they have experience with both methods. In each method the dialog has different structure due to the different context information available to the help- ing person (called navigator) and lost blind person. In our research we focus on the second method, navigation through mobile phone call. Balata et al. (2013b) showed that such method is usable and navigator can successfully guide blind person in outdoor environment. This is because the blind person is able to efficiently describe his/her po- sition. Balata et al. (2013a) found that there is

Exploring haptic interfacing with a mobile robot without visual feedback

Exploring haptic interfacing with a mobile robot without visual feedback

Search and Rescue scenarios are often complicated by low or no visibility conditions, because of smoke or dust. The lack of visual feedback causes significant stress for human rescue workers. If a group of robots could overcome the navigation and localisation problems, they would become assistants to a human rescue worker. Trials were held with professional fire fighters; however it became clear that the human subjects by no means were prepared to give up their procedural routine. Following on from these (disappointing) findings we are exploring the context for using a robotic device in no-visibility conditions. In such conditions a haptic interface seems a natural solution and we investigate and experiment with how a human and a semi-autonomous robot can develop cooperation and become a team. The final aim is to design a robotic system and interface that will provide the human with some trust and confidence. In this paper we explore the basic design requirements for haptic human-robot interaction, starting from reviewing the interaction between a blind person and a guide dog.

ABSTRACT: Blind stick or white cane is introduced to blind people after the First World War as a mobility tool to

In [5] the Voice Enabled Smart Walking Stick for Visually Impaired persons was proposed. Their proposed system consists of a simple walking stick equipped with ultrasonic sensors to give information about the environment such as object detection, pit sensing and water sensing. GPS technology is integrated with preprogrammed locations to determine the optimal route that the blind should navigate. Also, a voice enabled equipment switching is provided to help the blind person in private domain. The proposed system used two Ultrasonic detectors which are Pit sensor and Water sensor; GPS receiver, GSM module, Voice synthesizer, ATmega328/P microcontroller, relay, speaker and battery. The GSM module and relay are for the purpose of switching on the equipment. It helps in transferring the information about the needed operation to be performed on the equipment and generates the resultant switching action. The central merit of this system is that it helps the blind people in both inside and outside, care-free navigation. The GPS based blind device with user input interface signals the blind person when he/she reaches the destination by voice. The integration of room equipment switching along with this system makes it even more useful, thus making it suitable for both indoor and outdoor environment. The smart stick not only aids in detecting obstructions placed at a distance in front of the user, but also provides real time assistance via GPS. The information regarding barriers is given through voice alerts that eradicate the problem of understanding vibration patterns which was used in previous systems. Their system is a reasonable budget navigational aid for the visually impaired. The cost effectiveness of the proposed solution leads to compromises in performance. Some improvements that could be made are as follows: Increasing the range of the ultrasonic sensor, and implementing a technology to determine the speed of the approaching obstacle. Also, running this integrated set of hardware requires an alternative to the battery. It should also accommodate wide varying grips for flexible handling. Their proposed combination of various working units makes a real-time system that monitors position of the user and provides dual feedback making navigation more safe and secure.

Designing Of Navigation System for Blind People Using Gps & Gsm Techniques

Designing Of Navigation System for Blind People Using Gps & Gsm Techniques

[5] ABDEL ILAH NOUR ALSHBATAT: The system is Automated Mobility and Orientation System for Blind or Partially Sighted People Currently, blind people use a traditional cane as a tool for directing them when they move from one place to another. Although, the traditional cane is the most widespread means that is used today by the visually impaired people, it could not help them to detect dangers from all levels of obstacles. In this context, we propose a new intelligent system for guiding individuals who are blind or partially sighted. The system is used to enable blind people to move with the same ease and confidence as a sighted people. The system is linked with a GSM-GPS module to pin-point the location of the blind person and to establish a two way communication path in a wireless fashion. Moreover, it provides the direction information as well as information to avoid obstacles based on ultrasonic sensors. A beeper, an accelerometer sensor and vibrator are also added to the system. The whole system is designed to be small, light and is used in conjunction with the white cane. The results have shown that the blinds that used
