A visual communication device for displaying combinations of written words which are entered by manipulation of an efficiently organized keyboard. The keyboard has certain keys specifically dedicated to a set of the words recurring most frequently in common conversational language as well as keys corresponding to discrete letters of the alphabet for spelling less-frequently used words. The keyboard is backed up by an extensive list of common terms stored in a memory. Each word is automatically fetched from the memory and displayed on a multi-digit alpha-numerical readout as soon as a number of leading characters sufficient to identify the word has been entered; thus, dispensing the operator from keying the remaining characters. In this first version, the device can be used by a person with auditory or vocal disability to quickly enter phrases in the readout by a much lesser number of manipulations than would be required if each word had to be spelled one letter at a time on the keyboard.
