SonicVisioN's airborne ultrasonic imaging technology enables the Blind and mobile robots to perceive objects. Observation of blind persons using Kay's very high resolution ultrasonic spatial sensors over a period of many years has generated insights to mobility which may not otherwise have occurred. The sensor is mounted on the head of a blind person and the output stereo sounds fed to the ears by miniature earphones to produce immediately a dynamic real-time neural image of object space.
Comprehension is learned over a period of time.

The two outputs from the FFT processor can then be further processed by software to model the auditory neural system so as to generate high resolution location of objects forming the environment. Software to provide the visual display of location of multiple objects in a field of view of 90 degrees is developed. This can be used by a teacher to better understand the spatial significance of the sounds. Software for classification and identification of objects is under continuous development.
