Acoustics help blind people start to see the global world The EU-funded CASBLiP project was conceived to integrate the image processing and acoustic mapping technologies right into a single, portable gadget that could be worn by blind people and help them to navigate outside. The University of Laguna proved helpful to adjust its acoustic mapping program and the University of Bristol refined its picture processing algorithms sildenafiluk.org . These devices includes a gyroscopic sensor developed by the University of Marche also, Italy. This component, called the head-positioning sensor, detects the way the wearer moves his head. It feeds back again the position of the top and the direction it is facing, so the relative position of the sounds being performed to the wearer also move as expected.
