Optimization of Key Frequency in Keyboard Using Mathematical inclusion of Design

Computer Engineering

A keyboard for computers has a plurality of alphabetic characters assigned to keys in three rows corresponding to letter assignments in upper row, middle row and lower row. Keyboard contains a set of keys divided into four sections as Text Entry Section, Navigation Section, Numeric Keyboard Section and Function Key Section. The standard QWERTY keyboard layout was developed in late 1800’s. Since then, people got acquainted with the same layout; so was retained for the computer keyboards. The conventional keyboard layout was earlier designed for the mechanical typewriters to avoid piling up striking levers on one another; so, it was not efficient to be used with the modern computer systems. In order to improve the key arrangements for the efficient and faster typing, the anatomy of human finger must be analyzed. It includes the distribution of the load properly on the stronger fingers for the more key pressing while the dynamic fingers to more movements; so that, maximum advantage of the layout may be yielded
