Very good condition with little to no wear to covers. Internally clean and bright.
Communicating comes naturally to us. Most people use speech very early in their lives for this purpose without thinking twice about it.
It is therefore understandable, though regrettable, that in our communicating world, people who cannot speak are isolated from the rest of society. In the past ten years or so, however, various graphic communication systems (using pictures, symbols and words) have been develed so that non-speakers also may express their needs and ideas by pointing to the different components of a communication display.
But, when the aphonia is caused by a motor deficiency which also affects control of the upper limbs, pointing with a finger can be difficult. Various adaptations or technical aids must therefore be developed so that the use of a communication display can either be made possible or easier.
This book contains a variety of practical ideas already being put to use in this field. They have been gathered from difference centres both in North America and overseas. Most descriptions are concise and no detailed diagrams are provided. The intent is not to give hard and fast recipes, since every non-speaking person has specific needs requiring tailor made solutions, but rather that these ideas may, in turn, serve as a catalyst for others.
