All compounds indexed in Chemical Abstracts since 1965 (vol. 62) have been allotted a Registry Number, based on an algorithm for generating a machine-language representation of the two-dimensional and stereochemical arrangements of atoms and groups of chemical compounds. The... 

Technology-based AAC systems have taken two forms hardware designed specifically for this application and software that runs on mass market computer hardware. Three basic components comprise AAC systems. These are the language representation method (including acceleration techniques), the user interface, and the outputs. Generally, a multidisciplinary team evaluates the current and projected skills and needs of the individual, determines the most effective language representation method(s) and physical access technique (s), and then selects a system with characteristics that are a good match.
