The problem of using the cane is the users should actively use it to grope anything infront of him. The cane can not detect the other obstruction which is far from the users and it absolutely makes the users uncomforted.Another problem is the white cane just only can detect by groping or tactile objects.The application of ultrasound wave on white cane for the visually impaired person is based on sonar to detect any obstruction toward the man.
