Development of Sensors to Aid the Blind
From: Medical Design Technology - 12/11/2013

Researchers from the University of Wollongong have advanced our understanding
of the most effective echolocation techniques, which could be used to develop
better navigation aids for the blind and to create high-tech robots to rescue
people from disaster scenes.

Robotics engineer Dr Shérine Antoun led the study, which will be published in
the December issue of IEEE Sensors Journal. By setting up a navigation
experiment using techniques learnt form observing how blind people use
ultrasonic mobility aids to navigate corridors (whether they track the wall
of the corridor, the free space or a combination of the two), the researchers
have discovered a wealth of previously unknown data contained in the
backscattered ultrasonic echo and have developed an optimal sensor scan
motion.
