Method and system for determining proximity of an object |
| 摘要 |
A first sensor detects whether an object is within a first region that surrounds the first sensor. A second sensor detects whether the object is within a second region that surrounds the second sensor. The first and second sensors are omnidirectional capacitive electrodes. In response to the first sensor detecting that the object is not within the first region, a device determines that the object is not proximate to a particular side of the first and second sensors. In response to the first sensor detecting that the object is within the first region, and the second sensor detecting that the object is within the second region, the device determines that the object is not proximate to the particular side. In response to the first sensor detecting that the object is within the first region, yet the second sensor detecting that the object is not within the second region, the device determines that the object is proximate to the particular side. |

1. A method performed by at least one device for determining proximity of an object, the method comprising:
with a first sensor, detecting whether the object is within a first region that surrounds the first sensor; with a second sensor, detecting whether the object is within a second region that surrounds the second sensor, wherein the first and second sensors are omnidirectional capacitive electrodes, and wherein the object is unrestricted to approach the first and second sensors from front and rear sides of the first and second sensors; in response to the first sensor detecting that the object is not within the first region, determining that the object is not proximate to a particular side of the first and second sensors, wherein the particular side is one of the front and rear sides; in response to the first sensor detecting that the object is within the first region, and the second sensor detecting that the object is within the second region, determining that the object is not proximate to the particular side; and in response to the first sensor detecting that the object is within the first region, yet the second sensor detecting that the object is not within the second region, determining that the object is proximate to the particular side. |
