Abstract:
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.
