Project Summary

Virtual Blind Assistance is being developed to guide blind persons via voice instructions in indoor and outdoor  environment. The assistance will detect objects, recognize them and guide the blind person to plan his path. The objects to be detected and recognized include house furniture, humans and walls , vehicles , and other things  

The blind person wear glasses in which camera is attached also that  person have hand free and a mobile phone so that when a person see anything from camera send  the input to your mobile phone then mobile phone process it and give the audio to the hand free by this method blind person know the things that is in front of him

Project Objectives

• To assist a blind person in his daily life without interaction of human being.

• To include feature of object detection and object recognition.

• After recognizing object, the system will play an audio to guide the blind person.

• it includes all aspect of life , like moving ,news paper  reading and other things reading , meeting people and their behavior , shopping , face detection , food checking , and all aspect of life

Project Implementation Method

 

During the Implementation phase, the project plan is put into motion and the work of the project is performed. It is important to maintain control and communicate as needed during implementation. Progress is continuously monitored and appropriate adjustments are made and recorded as variances from the original plan.

Hence as part of execution we broke our Virtual Assistance to modules for a broad view of the project and to strategize easily for further implementation and tracking through out.

Modules

Developing your own Voice Assistant App

For now we will be using custom voice assistance provided to us by the gTTS, STT or TTS free libraries provided open source, for later on broad production and our own identity we might be developing our personal assistant voice api.

Voice/speech to text (STT)

This is the process of converting speech signal into digital data (e.g., text data). The voice may come as a file or a stream. You can use CMU Sphinx for its processing.

Text to speech (TTS)

This is the process of converting digital data (e.g., text data) into speech signal. The voice may come as a file or a stream. We might use gTTS for its processing.

This process translates text / images in a human speech. It is very useful when, for instance, a user wants to hear the correct pronunciation of a foreign word.

Intelligent tagging and decision making

Intelligent tagging and decision making serve for interpreting the user's request. For example, in our current perspective the user may ask: 'I want to reach certain destination'. The technology will tag few appropriate path and suggest you a few according to your interests. We are overseeing multiple APIs for our certain needs.

Image recognition

Image recognition is the most important part of our virtual assistant project and the mighty module we are focusing on, we’ve considered and have been working on OpenCV because of the bigger community size that could help us in any point of error. We will be considering deep learning model be practiced and matching accuracy of our need in OpenCV through image recognition/ object detection/ classification, clustering/ or mapping.

Benefits of the Project

Virtual assistants can make it feel like secretaries have come back in style. Some examples includes for major perspective for Blinds are:

• Guiding you through your path of the destination of your choice
• Guiding you safely throughout
• Reading your email and messages to you and even replying,
• Finding out the weather forecast and reporting news you’re interested in hearing.
• help during meeting with new people and old people tell their age , behavior , looks etc
• help during shopping , currency exchange 
• Read documents , newspaper  and email
• Tell about the environment during walk like moving people , vehicle , playing children etc
• Providing reminders so you never miss a meeting,.
• Adding items to your to-do list,
• Making conference calls for you so you don’t have to remember to bring the number,
• Finding flights, lodging and restaurants for you locally or when you travel,

Technical Details of Final Deliverable

In the final deliverable we will integrated system in which Bluetooth glasses , Bluetooth hand free and mobile are attach to each other through hand free , and mobile is connected to a cloud server

, so we will show following functionality during final testing of the project

A blind person wear a glasses along with the hand free and a mobile phone in his pocket, so when person start walking the things that can see by camera will detect using Open CV and then that result will send to mobile and then mobile process it through Cloud server using deep learning algorithms and then cloud server tell the result of the things to the mobile and mobile send that result to the hand free using text to speech and blind understand the  

It tell about the following things:

• Outdoor environment :  like moving people , moving vehicle , playing children
• Indoor environment : like taking with people and their behavior , face detection ,
• Path planning for blind person
• Shopping item selection and tell blind about that things

here is the diagram for our final Deliverable  :
