Character and text unit input correction system
View Patent ↗An input device is disclosed that includes a sensor for editing characters and text units. The sensor has an elongate configuration and is laterally-oriented with respect to sides of the input device. The input device also includes a plurality of keys for entering individual characters or multiple characters that form the text units. By contacting the sensor, an incorrectly-entered text unit may be selected and replaced with an intended text unit. In order to select the incorrectly-entered text unit, the sensor may be contacted in a position that corresponds with a position of the text unit with respect to a display screen.
1. An input device comprising:
an alphanumeric region having a plurality of depressible keys for entering characters associated with text units that are displayed on a display screen; and
an elongated, laterally-oriented, and touch-sensitive sensor positioned adjacent the alphanumeric region, the sensor having a plurality of zones distributed along a length of the sensor, each zone corresponding with a position at which the text units are rendered on a line of the display screen, and the sensor having a configuration wherein contacting one of the zones transmits a signal for selecting one of the text units positioned at a corresponding location on the line of the display screen.
2. The input device recited in claim 1 , wherein the length of the sensor is at least four times a width of the sensor.
3. The input device recited in claim 1 , wherein the sensor is positioned behind the alphanumeric region.
4. The input device recited in claim 1 , wherein the input device is a keyboard.
5. The input device recited in claim 1 , wherein the sensor is positioned adjacent the alphanumeric region.
6. The input device recited in claim 1 , further comprising at least one text unit sensor supporting input element to assist in editing the text units.
7. The input device recited in claim 6 , wherein the input element includes three discrete keys.
8. The input device recited in claim 6 , wherein the input element includes a toggle key.
9. The input device recited in claim 6 , wherein the toggle key is a three-way toggle key.
10. The input device recited in claim 1 , wherein the zones are unmarked areas along the length of the sensor.
11. The input device recited in claim 1 , wherein the sensor is positioned directly behind the alphanumeric region.
