Abstract

Data input may be effected with a keyboard including a first keypad having five keys and a second keypad having five keys. The keys of the first keypad are correlated with columns of a 5×5 matrix including 25 cells, where each of the five keys of the first keypad is associated with one column. The keys of the second keypad are correlated with rows of the 5×5 matrix, where each of the five keys of the second keypad is associated with one row. Each combination consisting of one key from each of the first and second keypads is thereby associated with one of the 25 cells in the 5×5 matrix, and each cell of the 25 cells contains content. One key from each of the first and second keypads activated, and the content from one of the 25 cells is input based on the activated keys. This input is repeated until data entry is complete.

Claims

1. A keyboard data input system operatively coupleable with a device including a processor and a display, the keyboard data input system comprising:

a first keypad including five keys, wherein each of the five keys of the first keypad is correlated with one column of a 5×

5 matrix including 25 cells;

a second keypad including five keys, wherein each of the five keys of the second keypad is correlated with one row of the 5×

5 matrix,

wherein each combination consisting of one key from each of the first and second keypads is thereby associated with one of the 25 cells in the 5×

5 matrix, and wherein each cell of the 25 cells contains content; and

an accessory finger guide positionable over the first and second keypads, the accessory finger guide including restraining members that prevent a user'"'"'s fingertips from depressing the keys of the first and second keypads until a prescribed amount of pressure is applied by the user'"'"'s fingertips.
