Survey on Flux Sensor Based Text Recognition System

There are several barriers for the blind people to communicate with the external world through mobile phones or computers. For people with visual disabilities, the mode of Human Computer Interaction (HCI) primitively designed for sighted people are highly inconvenient to use. Different devices are invented to overcome this problem using Braille language. This paper audits some current problems that are frequently encountered when visually impaired people access computer facilities using 'conventional' techniques such as Braille displays, speech synthesis equipment and screen enlargement techniques. Good communication is crucial to our relationships and membership of social groups for them to be satisfying and meaningful. A person, who is deaf-blind or has sensory impairments, depends on communication that is clear, concise and accessible for a good quality of life. They may face great difficulty in knowing for certain what is happening around them or in communicating with those they meet. Deaf-blind people use many different methods of communication. The method or methods used will depend on the amount of residual sight, hearing and any additional disabilities the individual has. It will also depend on whether the individual has learned formal language before becoming deaf-blind.
