An Efficient Interaction of Blind People with System using Braille and Image Coordinates Positioning Methodology

Abstract

This research work focus on the study of blinder performance for which very few of research has been analysed, but this research work was taken into account for using E-speech, Speech coordinate positioning and colour coding system for improving their performance. It consists of different mode of operations along with suitable kits. It is used to communicate the information between blind people and system without help of others. By using Braille and colour coding kit blind user can easily type words, numbers, and symbols with colours. This system helps blind person to recognize text and colour selected by text to speech synthesis. While they typing text and selecting colour it will spell for them to recognize whether they have given correct input or not. It is a major tool helps blind people to communicate with system. The typed words are recognized to deliver the audio of the typed words using Braille system. The collections of words are stored in the corpus. This has inherited the problem of concatenation junctions and its time delay in concatenating larger units in case of generating polysyllables. To overcome the above mentioned problem the corpus is used here in English. Next speech to coordinate positioning used to draw basic drawing like circle, straight line, rectangle, polygon and square etc. Here this SCP user interface get 2 types of input first is getting voice input. This method is to get voice input where this system let the user to select appropriate tool from the user interface by spelling them and it should be followed by necessary coordinates to complete the drawing successfully. With this input the system can draw basic objects easily. And another method is getting input using track pad coordinates from blind people for drawing objects. A track pad will be provided to the blind people for drawing objects. By using fingers they can draw basic drawing in track pad. The coordinates from the drawing pad will be recorded and shown in screen as actual object.
