Abstract
A compact input device for fast text input. Ten perimeter regions are defined in a decagon shaped ring on a touch pad, and nine more center regions arranged in a 3 by 3 matrix are defined at the center of the perimeter regions. In alphanumeric mode, each of the ten perimeter regions represents a numeral or a character of the same order, found on a corresponding key of the ten numeric keys, 0 to 9, found on a standard 12-key telephone keypad. All perimeter regions synchronously switch to another group of characters of the same order, in accordance with the direction of a swipe on any of the perimeter regions. A tap on a perimeter region selects the character represented by the region at the moment. In addition, it is capable of operating in a standard 12-key telephone keypad mode, pointing device mode, and symbol mode.
