Abstract
A rounded keypad device capable of being operated with only one finger comprises the invention. The keypad device includes a keypad having keys, which are positioned within a movement radius of the finger of an operator and have the English letters required for forming desired words or numbers or functions to be executed. The keys are arranged in a high using-frequency key section involving first set keys among the keys of the keypad, the first keys being assigned to English letters and functions that are relatively frequently used when inputting letters and function executing instructions. The first keys being positioned in a round configuration which is defined around the eye's focal point on the keypad and in a minimum movement radius of the finger of the operator, along a first virtual circle. The keypad also includes a second low-using frequency key section comprising remaining second set of keys among the keys of the keypad, the second keys being assigned to English letters and functions that are relatively infrequently used when inputting letters and function executing instructions. The second set of keys is arranged in a rounded configuration concentric with the rounded configuration of the first set of keys and having a radius larger than the minimum movement radius. Various mode and function switches are also provided and the geometric configurations can be used with a variety of keypads and for inputting a variety of devices.
