Sensory 6*: Ultrasonic Mobility Aid for the Blind

The objective of this paper is to introduce the Sensory 6, a new hands-free ultrasonic travel aid (ETA) for the blind and to describe the process which culminated in its development. The main function of any ultrasonic ETA is to extend the user’s perception to include the environment beyond body space. Ultrasonic ETAs extend the user’s space by using the principle of ultrasonic radar. Essentially, high frequency ultrasonic signals are emitted when an object is present within the functional range, a portion of the sound waves is reflected back to the ETA Receiving transducers detect these returned sound waves and translate them into signals that the user can interpret. Being able to sense distant objects can affect the lifestyle of the blind in several ways, to help the user locate obstacles and to serve as an environmental sensor. An environmental sensor can be used to locate obstacles, but generally its more important function is to help the user develop concepts of space.
