Wireless and uninstrumented communication by gestures for deaf and mute based on Wi-See technology

The fact that technology is advancing as per Moore's law, the attention towards deaf and mute individuals with hi-tech technology is not much.Deaf and mute have to communicate through sign language even for pithy things.And also many people did not understand this language.Now-a-days gesture is becoming an increasingly popular means of interacting with computers.This paper sheds light of an proposed potential idea relying on latest technology named Wi-See which was developed in Washington, US.This technology actually uses our conventional Wi-Fi signals for home automation by gesture recognition.So, depending upon this hi-tech technology, my modified application idea is towards deaf and dumb, especially, one who cannot speak, but knows English language for communication.Since wireless signals do not require line-of-sight and can traverse through walls, proposed idea can be very useful to expressed views by speechless people without requiring instrumentation of the human body with sensing devices.The whole idea is based on Doppler shift in frequency of Wi-Fi signals.Instead of controlling home appliances as by Wi-See, this idea extends its view for speech or words through speakers installed.Each successive pattern of English alphabet generated by Doppler shift by gestures in air, can be recorded and matched with predefined pattern, which when processed, be outputed through speaker as combined letter word ,inspired by English digital dictionary having prediction and correction algorithm.
