Abstract: This disclosure generally provides an input device with near-field and far-field receiver electrodes. Using resulting signals captured by these receivers, the input device generates a near-field capacitive image and a far-field capacitive image. In one embodiment, the near-field capacitive image contains information identifying a location of an input object in a first plane in free space, while the far-field capacitive image contains information indentifying a location of the input object in a second plane in free space. Further, the first and second planes may be parallel planes where the first plane is closer to an input surface of the input device than the second plane. In one embodiment, the input device compares the information in the near-field and far-field images in order to determine a state of the input object.
