The invention also includes adhesive backed colored appliques matching the sector-color-coding which can be removably applied to the fingers or another support to provide a means for initial learning of the method prior to practicing the method. Finally, the keyboard is covered with the color appliques according to the predetermined sector color code and a look-away image of the predetermined sector-color-coded keyboard is provided to prevent the user from looking at the keyboard while typing. This system can also be applied to other multiple finger actuated input devices. | InventorApplicationNo. 951139 filed on 09/25/1992US Classes:434/227, Keyboard operation (e.g., typing, key punching, etc.)434/233Means on hand or finger for indicating finger to be usedField of Search434/159, Alphabet letter formation, recognition, or sequencing434/227, Keyboard operation (e.g., typing, key punching, etc.)434/233Means on hand or finger for indicating finger to be usedExaminersPrimary: Mancene, GeneAssistant: Thomas, L.
