Methods, systems and devices are described for determining positional information for objects using a sensing device. The various embodiments provide improved user interface functionality by facilitating user input with both objects that are at the surfaced and objects that are away from the surface. The sensor device includes a processing system and a sensor array of sensing electrodes adapted to capacitively sense objects in a sensing region. First, the processing system is configured to determine positional information for objects at the surface in a first portion of the sensing region. Secondly, the processing system is configured to determine positional information for objects that are away from the surface and in a second portion of the sensing region, where the first portion of the sensing region is between the surface and the second portion of the sensing region. |
