This research aimed developing a superior level supporting system and related terminal for the cognitive defectives to simple warning devices. The practical purpose was developing a vision reconstruction system using auditory input based on theory of comprehensive cognition. In cerebral anatomy, at some spots, visual and auditory neural tracts approach closely and new neural tract used to be activated as a compensatory mechanism for the defective area. These facts were tried to be enhanced by this vision reconstruction system (Audiovision). The “ Audiovision” system was developed for acquiring front visual information and for delivering it to the subject as an auditory signal. This system simulates visual stimulation not as a simple warning device. Additionally bone conduction earphone was adopted for more efficient delivery of auditory signal. The fusion technology of audio and vision, which is the core technology of the Audiovision system, was the nation’ s first attempt and we have already secured a patent-based technologies. Since existing researches were limited to simple assist technology with single function or extreme IT-oriented technology, the comfort of subject was not fully considered. Since this research project is practically achievable and could prodcue a commercial version, a practical benefit for the blinded person is possible and this point is merit of this research project. The Audiovision system has a property that a higher function can be provided according to the level of training. Novices can start with low-resolution information. If subjects are trained to recongnize the auditory output signal, the resolution of visual data can be increased for higher resolution vision reconstruction. Using the 4th component of audiotory sense, sound color, superior function of Audiovision to reconstruct color or texture of objects will be possible. Other perspectives of this product are as below:
① In routine living, the dead zone of vision can be detected.
② In industrial area where noise and obstacles exist, comprehensive cognitive function can be enhanced.
③ By adding IR stereo camera function, this system can be modified to military product. -> Vision supporting system during lightl-less operation
④ This system can be applied on a dead zone detection system for the next generation smart car
