ABSTRACT:
An ergonomically developed key input system for use with a computing or electronic handheld device that uses chording to type at increased speeds. The key input system includes a set of finger input keys corresponding to the fingers of a user's hands that are divided into at least three subkeys, each subkey adapted to be engaged simultaneously with any other subkey. Simultaneous engagement of the finger subkeys creates an input signal that corresponds to a grouping of input values, which are translated by software to display a word or perform a function. Thumb keys may be used in conjunction with the finger input keys to perform additional functions. The key input system disclosed utilizes a chording principle to type words and perform computing functions with only slight movements of a user's hands from an initial relaxed position.
