ABSTRACT:
A data entry system for use with one hand that includes nine primary keys and four secondary keys. The nine primary keys are arranged in three symmetrical rows of three keys each and, thereby, form three symmetrical columns of three keys each. These primary keys are positioned and constructed for operation by the index finger, the middle finger, and the ring finger of a user. Two secondary keys are positioned proximal the primary keys so that when the user's hand is properly positioned on the keypad, the user's thumb is naturally proximal the thumb keys (for right hand use). Likewise, two secondary keys are positioned proximal the primary keys such that when the user's hand is properly positioned on the keypad, the user's pinky finger is naturally proximal the secondary key (for right hand use). For left handed users, the data entry system is also provided with a selector switch which inverts the characteristics of the two sets of secondary keys. Depending on whether a primary or a secondary key has been depressed and on whether two keys are concurrently depressed, the data entry system permits entry of a pre-programmed character or function at the release of one key, at the concurrent and non-sequential depression of one primary and one secondary key, or at the concurrent sequential depression of two primary or two secondary keys. Thereby, the thirteen key layout described provides for efficient, comprehensive data entry using one hand.
