Color-coded data input system method and apparatus

A method of learning operations on a color-coded data input device comprising the steps of:

• providing a student with a sector-color-coded data input device having a plurality of keys wherein each of said keys is associated with at least one key symbol and each of said key symbols is covered with a removable colored applique whose color correlates with a predetermined color code which divides the plurality of keys into sectors, and a set of color-coded flash cards comprising a card for each key symbol which corresponds to the predetermined sector-color-code of the plurality of keys of the input device wherein each of said cards comprises a facsimile of a portion of the sector-color-coded data input device which contains the key symbol associated with the card;
• and
• flashing the set of cards so that the student views the cards one at a time in order to learn where the key symbols are located on the sector-color-coded data input device.

A set of flash cards for teaching operations on a sector-color-coded input device having a predetermined sector-color-code and a plurality of keys wherein each key corresponds to at least one key symbol and each at least one key symbol is associated with a color, said set of flash cards comprising a card for each key symbol on the sector-color-coded input device, each of said cards having front and back sides wherein said front side comprises a reproduction of the key symbol in a form which is uniform for the entire set and said back side comprises a reproduction of at least one of a right half and a left half of the sector-color-coded unit which contains the key symbol indicated on the front side of the card.
