International ClassG09G 500AbstractA data-entry device having manually operable input means arranged in zones for operation by corresponding fingers of a user. The device includes means for color coding such that each zone is assigned a color and successive zones display colors ordered according to their relative positions within a spectrum-ordered color pattern. In one embodiment the device includes a keyboard, such as for a computer or typewriter, wherein the keys of the keyboard are color-coded according to a spectrum-ordered color pattern. The invention also provides a method of color coding a data-entry device.Field of SearchIncluding keyboardPortable (i.e., handheld, calculator, remote controller) Light source associated with each key Transparent substrate having light entrapment capability (i.e., waveguides) Keyboard operation (e.g., typing, key punching, etc.) Means on hand or finger for indicating finger to be used Color-coded key-board Key-board including keys grouped to facilitate positioning of typist's fingers To or from coded mark inversion BODILY ACTUATED CODE GENERATOR For handicapped user Including keyboard or keypad Keyboards For keyboard On keyboard |
