FINGER SENSING DEVICE AND METHOD |
| 摘要 |
A finger sensing device includes a first conductive plate, wherein the area between the finger and the first conductive plate increases in response to the finger moving in a first direction proximate the first conductive plate. A second conductive plate is located proximate the first conductive plate, wherein the area between the finger and the second conductive plate decreases in response to the finger moving in the first direction proximate the second conductive plate. A first capacitance detector is coupled to the first conductive plate for measuring a first capacitance between the finger and the first conductive plate. A second capacitance detector is coupled to the second conductive plate for measuring a second capacitance between the finger and the second conductive plate. |

1. A finger sensing device comprising:
a first conductive plate, wherein the area between the finger and the first conductive plate increases in response to the finger moving in a first direction proximate the first conductive plate; a second conductive plate located proximate the first conductive plate, wherein the area between the finger and the second conductive plate decreases in response to the finger moving in the first direction proximate the second conductive plate; a first capacitance detector coupled to the first conductive plate for measuring a first capacitance between the finger and the first conductive plate; and a second capacitance detector coupled to the second conductive plate for measuring a second capacitance between the finger and the second conductive plate. |
