[rehab] echolocation

[Gene Bourquin DHA]

RJ,
In simple terms, echolocation is the use of sound to know where objects are in the environment, and where you are in relation to those objects.  The term 'reflected sound' is also use.  Daniel Kish, practitioner who is blind, is a specialist on this topic.  You can read about echolocation at this URL: http://en.wikipedia.org/wiki/Human_echolocation
O&M is not static field, although I would judge our progress as slow.  Many of the practices we use are decades old.  That said, new research and finding are made and written about each year.  For example, recent research on cane use and cane equipment (tips) has found significant benefit to using a constant contract technique in detecting drop offs.  Also, streets, intersections, and traffic signals are changing all the time, because of technology.  Your instructor should be able to address the changes and instruct you fully in crossing streets.
I hope that helps.  I'll look forward to hearing others' input.

Best.
Gene

> To the ONM specialists on this list, What is echolocation, and what is its purpose? Secondly, people have told me orientation and mobility is a nonchanging discipline, that the Techniques are all the same. I took mobility eleven years ago, and now I'm taking it again. Will I notice any changes? RJ
