Picture Exchange Communition System
The Picture Exchange Communication System is an example of low technology in autism treatment. Low technology in the treatment of autism and related pervasive
developmental disorders involves any assisting technology that requires
no batteries or electricity to run.
Any time a parent or professional uses an object, visual representation or written text, he is using a form of low technology. This simple approach is one of the most valuable interventions in the treatment of autism and related pervasive developmental disorders.
Low technology is used in the home, school and community setting and is inexpensive and accessible to those involved with the child. This form of technology is helpful in that it can provide visual aids that foster understanding.
It is also the least intrusive form of technology. People do not need to use complex equipment in order to use low technology. Common, everyday prompts, guestures and visual aids are used naturally.
