FINAL OBSERVATIONS
In many cases it is not easy to predict which communication methods will be more suitable or more effective. Two suggestions may help in the decision process.
It is much more suitable to act with flexibility, teaching two or more different methods which can suit different communication needs. It is usual that the same child learns to communicate his /her needs, for example, partly with gestures and partly through the use of signal-tags.
The most important thing is being able to communicate and therefore the disabled people can set up meaningful, adequate and functional relations with other people.
