Abstract: This is an input devices that allows any type of character to be quickly and easily entered into any computing device with one hand, while being held by the same hand. The characters are arranged in arrays that can be displayed in a format of rows and columns. The user maneuvers the cursor through the tables using wheel type directional switches that can index continuously if desired. Normally, the thumb moves one wheel, or a ball, which can move the cursor over both rows and columns, and the index finger moves the other wheel or ball which changes the characters in the rows or columns allowing access to an unlimited number of characters. When the user arrives at the desired character, a switch controlled by one of the other fingers on the same hand then enters that character into the device. Double clicking, or pressing the switch quickly twice can make necessary adjustments to the character as desired, such as capitalizing a letter, or adding an umlaut.
